United States Naval Construction Battalions, better known as the Navy Seabees, form the U.S. Naval Construction Force (NCF). The Seabee nickname is a
On 28 December 1941, Adm. Moreell requested authority to commission three Naval Construction Battalions. His request was approved on 5 January 1942 by Admiral Nimitz.

It was the site of racial strife to the point that the camp was fenced in and placed under armed guard. The Seabees were trucked to and from the docks in cattle trucks. Two naval supply depots were located at Waiawa Gulch. At wars end 12,500 African Americans would serve in the Construction Battalions.

During World War II Seabees were tasked outside the NCF in the USMC, NCDUs, and UDTs.
In early May 1943, a two-phase "Naval Demolition Project" was ordered by the Chief of Naval Operations "to meet a present and urgent requirement" for the invasion of Sicily. Phase-1 began at Amphibious Training Base (ATB) Solomons, Maryland with the creation of Operational Naval Demolition Unit # 1. Six Officers led by Lt. Fred Wise CEC and eighteen enlisted reported from Camp Peary dynamiting and demolition school. Seabees called them "Demolitioneers".
Naval Combat Demolition Units (NCDUs) consisted of one junior CEC officer, five enlisted, and were numbered 1–216. After that first group had been trained, Lt. Commander Draper Kauffman was selected to command the program. It had been set up in Camp Peary's "Area E"(explosives) at the dynamiting and demolition school. Between May and mid-July, the first six NCDU classes graduated at Camp Peary. While the program was at Camp Peary the men were given head-of-the-line privileges at the mess hall. The program was moved to Fort Pierce where the first class began mid-July. Despite the move, Camp Peary remained Kauffman's primary recruit center. "He would go back to the dynamite school, assemble the (Seabees) in the auditorium and say, ''"I need volunteers for hazardous, prolonged and distant duty."'' Fort Pierce had two CB units assigned, CBD 1011 and CBMU 570. They were tasked with the construction and maintenance of obstacles needed for demolition training.
The invasion of Normandy had 34 NCDUs. When the first ten arrived in England they had no CO. Lt. Smith (CEC) assumed the role, splitting them up to train with the 146th, 277th and 299th Combat Engineers. As more NCDUs arrived they did the same, with 5 combat engineers attached to each NCDU. Group III (Lt. Smith) did research and development and is credited with developing the Hagensen Pack. NCDUs had a 53% casualty rate at Normandy. Four from Utah beach later took part in Operation Dragoon.
With Europe invaded, Admiral Turner requisitioned all available NCDUs from Fort Pierce for integration into the UDTs for the Pacific. That netted him 20 NCDUs that had received Presidential Unit Citations and another 11 that had gotten Navy Unit Commendations. Prior to Normandy 30 NCDUs had embarked to the Pacific and another three had gone to the United States Eighth Fleet, Mediterranean. NCDUs 1–10 were staged at Turner City on Florida Island in the beginning of 1944. NCDU 1 was briefly in the Aleutians in 1943. The first NCDUs in combat were 4 and 5 with the 4th Marines on Green Island, Papua New Guinea and Emirau Island. Later, NCDUs 1–10 were combined to form the short-lived UDT Able. NCDUs 2, 3, 19, 20, 21 and 24 were assigned to MacArthur's 7th Amphibious Force and were the only NCDUs remaining at the war's end.

Prior to Operation Galvanic and Tarawa, V Amphibious Corps had identified coral as an issue for future amphibious operations. RADM Richmond K. Turner, Kelly Turner, commander V Amphibious Corps had ordered a review to get a grip on the problem. VAC found that the only people having any applicable experience with the material were men in the Naval Construction Battalions. Lt. Thomas C. Crist, of CB 10, was in Pearl Harbor from Canton Island where he had been in charge of clearing coral, coral heads. His being in Pearl Harbor was pivotal in Underwater Demolition Team, UDT history. While there he learned of the Adm. Turner's interest in coral blasting and met with him. The Admiral tasked Lt. Crist to develop a method for blasting coral under combat conditions and putting together a team to do it. Lt. Crist started by getting men from CB 10, but got the remainder from the 7th Construction Regiment. By 1 December 1943 he had close to 30 officers and 150 enlisted at Waipio Amphibious Operating Base on Oahu.
In November the Navy had a hard lesson with coral and tides at invasion of Tarawa, Tarawa. It prompted Adm. Turner to request the creation of nine Underwater Demolition Teams to address those issues. Six teams for VAC in the Central Pacific while the other three would go to III Amphibious Corps in the South Pacific. UDTs 1 & 2 were formed from the 180 men Lt. Crist had staged. Seabees make up the majority of the men in teams 1–9, 13 and 15. How many Seabees were in UDTs 10 and 12 is not listed, for UDT 11 they composed 20% of the team.
UDT officers were mainly CEC. UDT 10 had 5 officers and 24 enlisted originally trained as OSS Operational Swimmer Groups, Maritime Unit: Operational Swimmer Group II, but the OSS was not allowed to operate in the Asiatic-Pacific Theater, Pacific Theater. Adm. Nimitz needed swimmers and approved their transfer from the OSS to his control. The MU men brought with the swimfins they had trained with and the Seabees made them a part of UDT attire as quickly as the Navy Supply Corps, Supply dept. could get them. In the Seabee dominated teams the next largest group of UDT volunteers came from the joint Army-Navy Scouts and Raiders school that was also in Fort Pierce. Additional volunteers came from the Explosive ordnance disposal (United States Navy), Navy's Bomb disposal School, Marine Corps and U.S. Fleet.
The first team commanders were Cmdr. E.D. Brewster (CEC) UDT 1 and Lt. Crist (CEC) UDT 2. Both Teams were "provisional" totaling the 180 men Lt Crist had put together from the 7th NCR. Those men were put through five weeks of training by a United States Marine Corps Amphibious Reconnaissance Battalion, Marine Corps Amphibious Reconnaissance Battalion. They wore fatigues, life-vests and were expected to stay in their rubber boats like the NCDUs. At Kwajalein Adm.Turner ordered daylight reconnaissance, recon. It was apparent to the Seabees that staying in the boats would not get the Admiral the military intelligence, intel he wanted. Cmdr. Brewester's men all wore swim trucks under their fatigues. Ensign Lewis F. Luehrs, and Charp. Bill Acheson spent 45 minutes in the water in broad daylight and were the first team members recovered. Still wet and in their trunks they reported directly to Adm. Turner. He concluded what they had done was the only way to get accurate intelligence on submerged obstacles and conveyed that opinion to Chester Nimitz, Adm. Nimitz. At Engebi Cmdr. Brewster was wounded. The success of UDT-1 not following USMC Recon protocol rewrote the UDT mission model and training regimen. Ens. Luehrs and Charp. Acheson were each awarded a Silver Star for their initiative while unintentionally creating the UDT "naked warrior" image. Diving masks were uncommon in 1944 and some men had tried using goggles at Kwajalein.Naked Warriors, Cdmr. Francis Douglas Fane USNR (Ret.), St. Martin's Press, New York, 1996, p. 828 Diving masks were a rare item in Hawaii so Lt. Crist and CB Chief Howard Roeder had requested supply get them. A fortuitous observation by one of the men spotted a magazine advertisement for diving masks. A priority dispatch was made to the States that appropriated the store's entire stock. The UDTs adopted goggles independent of the OSS. When UDTs 1 and 2 returned to Hawaii Chief Acheson and three other UDT Officers were transferred to the 301st dredging CB. The 301st had 12 dredges saving Teams from blasting channels, but needed divers to get the job done. Ensign Leuhrs made Lt. and was a member of UDT 3 until he was made XO of team 18. Commander Brewster's purple heart got him out of the UDTs and elevated to Commander 7th NCR instead of back to CB 10.
Adm. Turner also requested the formation of a Demolition Training Center at Kihei. It was approved. The actions of UDT 1 provided the training model, making UDT training distinctly different from Fort Pierce's NCDU program. Lt. Crist was briefly the first training officer and emphasized swimming and recon until he was made CO of UDT 3. When UDT 3 returned from Leyte in the fall of 1944 it became the school instructors with Lt. Crist again OIC of training. The classes now included: Night operations (military), night ops, weapons, bivouacking, small Military tactics, unit tactics, along with coral and lava blasting. In April 1945, team 3 was sent to Fort Priece to instruct there. Lt. Crist was promoted to Lt. Cmdr. and sent back to Kihei. Team 3 would train teams 12–22. UDT 14 is called the first "all fleet team" even though it had Seabees from Team Able and the CO and XO were both CEC. UDT 15 was the last team formed of NCDUs. Teams 12–15 were sent to Iwo Jima. Three cleared the shoreline for five days, D+2-D+7. After July 1944 new UDTs were only USN. In 1945, CBMU 570 was tasked to the UDT coldwater training center at ATB Oceanside, CA.
On Guam team 8 requested permission to build a base. It was approved by AdComPhibsPac, but disapproved by Island Command. Team 8 turned to the CBs on the island and got everything needed. Coral paving got placed the night before Admiral Nimitz inspected, giving teams 8 & 10 a glowing review.
By V-J day 34 teams had been formed.
Teams 1–21 saw actual deployment with the Seabees providing over half of the men in those teams. The Navy did not publicize the existence of the UDTs until post-war and when they did they gave credit to Lt. Cmdr. Kauffman and the Seabees. During World War II the Navy did not have a rating for the UDTs nor did they have an insignia. Those men with the CB rating on their uniforms considered themselves Seabees that were doing underwater demolition. They did not call themselves "UDTs" or "Frogmen", but rather "Demolitioneers" reflecting where Lt. Cmdr. Kauffman had recruited them from, the CB dynamiting and demolition school.
UDTs had to be of standard recruiting age, Seabees older could not volunteer. Mid-year 1945, in preparation for the cooler waters around Japan, a cold water training center was created. With it came a more demanding physical examination, physical. Team 9 lost 70% of the team to this change.
Postwar, MCB 7 was tasked with projects at the UDT training facility on St. Thomas, Virgin Islands
see Notes
In early 1946 the 53rd NCB was deployed with Operation Crossroads for the nuclear testing at Bikini Atoll. It was designated Task Unit TU 1.8.6. 53's project list included observation, instrument and communication towers, radio beacons, seismic huts, photo reference crosses, general base and recreational facilities, as well as dredging the lagoon. In addition, recreational facilities were constructed on Japtan Island for the ships crews of the Operation. The Battalion also assisted the relocation of the natives. They disassembled both the Community center and church for reassembly on Rongerik Atoll. In August the battalion was decommissioned with men transferred to CBD 1156 that was then commissioned on Bikini. The TU 1.8.6 designation transferred to the CBD. CBD 1156 remained for nine days after the second test.
UDT 3 was designated TU 1.1.3 for the operation. On 27 April 1946, seven officers and 51 enlisted embarked at CBC Port Hueneme for Bikini. Their assignment was to retrieve water sample (material), samples from ground zero of the Baker blast. In 1948, the displaced bikinians put in a request that a channel to the island Kili Island, Kili where they had been relocated be made. This was given to the Seabee detachment on Kwajelin who requested UDT 3 assist.
The 121st CB was decommissioned in December and re-designated CBD 1504. In January 1947 CBs 104 and 105 were reactivated. The 30th NCR was home-ported on Guam composed of CBDs 1501-13 and NCB 103. In 1949, the 103rd was made a Mobile Construction Battalion (MCB) while CBs 104 and 105 were made Amphibious Construction Battalions(ACBs). From 1949 until 1968 CBs were designated MCBs. In 1949, MCB 1 was reactivated at Naval Amphibious Base Little Creek, VA. In June 1950 the NCF totaled a few thousand.
The outbreak of the Korean War led to a call-up of 10,000 from the Seabee Reserve. Seabees landed at Battle of Inchon, Inchon during the assault, installing causeways dealing with enormous tides and enemy fire. Their actions there and elsewheres underscored the necessity of having CBs. During that war the authorized size of a CB was 550 men. When the truce was declared there was no CB demobilization as there had been at the end of World War II.
During the Korea, the U.S. realized the need of an air station in the region. Naval Air Station Cubi Point, Cubi Point in the Philippines was selected. Civilian contractors were approached for bids. After seeing the Zambales Mountains and the maze of jungle, they claimed it could not be done. The Navy then turned to the Seabees. The first to arrive was CBD 1802 to do the surveying. Naval Mobile Construction Battalion Three, MCB 3 arrived on 2 October 1951 to get the project going and was joined by MCB 5 in November. Over the next five years, MCBs 2, 7, 9, 11 and CBD 1803 all contributed to the effort. They leveled a mountain to make way for a nearly runway. NAS Cubi Point turned out to be one of the largest earth-moving projects in the world, equivalent to the construction of the Panama Canal. Seabees there moved of dry fill plus another 15 million that was hydraulic fill. The $100 million facility ($ in dollars) was commissioned on 25 July 1956, and comprised an air station and an adjacent pier that was capable of docking the Navy's largest carriers.
Seabee Teams
The World War II precursor to Seabee teams was the PT Advance base Detachment of the 113th CB. Each man was cross-trained in at least three trades with some qualified as corpsmen and divers. During Vietnam the requirement of being skilled in three trades was continued. The first Seabees referred to as "Seabee Teams" were CBDs 1802 and 1803. They were followed by Detachments Able and Baker. The U.S. State Department learned of the teams and concluded they could have a Cold War purpose. They could be U.S. "Good Will Ambassadors" to third world countries to counter the spread of Communism, a military version of the Peace Corps. These 13-man teams would construct schools, drill wells or build clinics creating a positive image for the U.S. They were utilized by the United States Agency for International Development and were in S.E. Asia by the mid-1950s. Then in the early sixties, the U.S. Army Special Forces were being sent into rural areas of South Vietnam to develop a self-defense force to counter the Communist threat and making use of the Seabee teams at these same places made sense to the CIA. To start, twelve "Seabee teams, with Secret Clearances, were sent with the Army's Special Forces in the CIA funded Civilian Irregular Defense Group program (CIDG)"Commander Naval Construction Battalion U.S. Pacific Fleet, Tân Sơn Nhất, Republic of Vietnam, Completion Report 1963–1972.
/ref> in the years 1963–1965. By 1965 the U.S. Army had enough engineers in theater to end Seabee involvement with Special Forces. At first teams were called Seabee Technical Assistance Teams (STAT) and were restricted to two in theater at a time. Teams after STAT 1104 were renamed Seabee Teams and by 1969 there were 17 in theater. As a military force Seabee Teams received many awards for heroism. Teams were sent to other nations as well. The Royal Thai government requested STATs in 1963 and ever since the Seabees have continued to deploy teams. Construction Civic Action Details or CCAD CCADs or "See-Kads" are larger civic action units of 20–25 Seabees with the same purpose as Seabee Teams. The CCAD designation is not found in the record prior to 2013.
Operation Highjump
In December 1946, 166 Seabees sailed from Port Hueneme on the USS Yancey and USS Merrick assigned to Operation Highjump. They were part of Admiral Richard E. Byrd's Antarctic expedition. The U.S. Navy was in charge with "Classified" orders "to do all it could to establish a basis for a (U.S.) land claim in Antarctica"."Operation Highjump" ''Air & Space Magazine'', July 2007, Smithsonian Institution, Washington, DC

/ref> In 1948, CBD 1510's men were transferred to CBD 1504 when it was replacing CB 121 as island Public Works. That year the CIA created the NTTU as a "cover" and made access highly restricted to the base. The CIA station had Capitol Hill, Saipan, Capitol Hill constructed to administer its operations at a cost of $28 million. The station covered the northern half of Saipan including, East Field (Saipan), Kagman Field, Marpi Point Field, and the four radio towers. "Brig. Gen. Edward G. Lansdale, Pentagon expert on guerrilla warfare, shared with Gen. Maxwell D. Taylor, President Kennedy's military adviser, on "Resources for Unconventional Warfare in SE. Asia."....that the "CIA maintains a field training station on the island of Saipan ... the installation is under Navy cover and is known as the Naval Technical Training Unit. The primary mission of the Saipan Training Station is to provide physical facilities and competent instructor personnel to fulfill a variety of training requirements including Espionage, intelligence tradecraft, communications, counter-intelligence and psychological warfare techniques. Training is performed in support of CIA activities conducted throughout the Far East area." The Seabees cease listing the Public Works assignments at NAS Tanapag in 1953 while the CIA remained until 1962. However, MCB 9 deployed to Saipan in 1954 with one of their projects being the up-grading of the Public Works shops. MCB 10 Det Bravo deployed to Saipan from July 1957 until February 1958 with projects unlisted.
* A year before the Bay of pigs and Cuban Missile Crisis the CIA took a "top secret" urgent/immediate project to the Seabees.Radio Swan: Seabees Part of Cold War History, Seabee Magazine online, Kenneth Van Belkum, Cmdr. CEC (retired), OIC of Det. Tango, Seabee Museum, Port Hueneme, CA
/ref> The agency wanted two 220' radio towers with a supporting airstrip, dock, and quonsets erected on Swan Islands, Honduras, Swan Island, built asap, with no construction plans for the Seabees. The station would be independent-self sufficient. Det Tango of MCB 6 was given the project. LSTs 1046 and 1056 delivered men and materials from CBC Quonset Point. The Seabees had the CIA's "Radio Swan" on the air in short order. Naval Intelligence: NAVFACs The Navy built 22 Naval Facilities (NAVFACs) for its Sound Surveillance System (SOSUS) to track Soviet submarines. They were in service 1954–79 with Seabees staffing all the Public works. In the 1980s the number of tracking stations was halved with the advent of the Integrated Underwater Surveillance System (IUSS). The NAVFACs were decommissioned by further advances in technology, the end of the Cold War and disclosures by John Anthony Walker, John Walker to the Soviets. The Seabees have also been tasked building Naval Communication facilities. One at Nea Makri Greece was built by MCB 6 in 1962 and upgraded by NMCB 133. United States Naval Communications Station Sidi Yahya El Gharb, Naval Comm Station Sidi Yahya was first built in World War II another is NavCommSta Guam. It started out on the island as the Joint Communications Agency (JCA) in 1945.
In 1964, at the height of the Cold War, Seabees were assigned to the State Department because listening devices were found in the Embassy of the United States in Moscow. Those initial Seabees were "Naval Mobile Construction Battalion FOUR, Detachment November". The U.S. had just constructed a new embassy in Warsaw. After what had been found in Moscow Seabees were dispatched and found many "bugs" there also. This led to the creation of the Naval Support Unit in 1966 as well as the decision to make it permanent two years later. That year William Darrah, a Seabee of the support unit, is credited with saving the U.S. Embassy in Prague, Czechoslovakia from a potentially disastrous fire. In 1986, "as a result of reciprocal expulsions ordered by Washington and Moscow" Seabees were sent to "Moscow and Leningrad to help keep the embassy and the consulate functioning".
The Support Unit has a limited number of special billets for select NCOs, E-5 and above. These Seabees are assigned to the Department of State and attached to Diplomatic Security. Those chosen can be assigned to the Regional Security Officer of a specific embassy or be part of a team traveling from one embassy to the next. Duties include the installation of alarm systems, CCTV cameras, electromagnetic locks, safes, vehicle barriers, and securing compounds. They can also assist with the security engineering in sweeping embassies (electronic counter-intelligence). They are tasked with new construction or renovations in security sensitive areas and supervise private contractors in non-sensitive areas. Due to Diplomatic protocol the Support Unit is required to wear civilian clothes most of the time they are on duty and receive a supplemental clothing allowance for this. The information regarding this assignment is very scant, but State Department records in 1985 indicate department security had 800 employees, plus 1,200 Marines and 115 Seabees. That Seabee number is roughly the same today.

Camp Nomad was a NMBC-74 project at Ras Al Mishab for MAG 26. Camps were constructed for both the 1st and 2nd Marine Divisions as well as Hq complexes for MEF I and II. In Saudi Arabia, Seabees built numerous camps, galleys, runways, aprons, helicopter, helo zones, plus two 500-bed Fleet Hospitals near Jubail, Al-Jubayl. The 3rd NCR was activated to provide a command echelon. NMCBs 24 and 74 also deployed in support of the Marines.

In Afghanistan, the Seabees' main task was the construction of multiple forward operating bases. NMCB 133 deployed to FOB Camp Rhino and help build Kandahar Airfield where a detention facility was constructed as well. O Since 2002, Seabees have provided civic action support in the Philippines, most notably near Abu Sayyaf's jungle training area in the southern Philippines. Seabees work with Army, Marines, and Air Force under the Joint Special Operations Task Forcem -Philippines. Seabees have supported the War on Terror ever since the invasion with numerous deployments over the years.

Trainees begin "A" School (trade school) upon completion of Recruit Training Command, Great Lakes, Illinois, boot: 4 weeks classroom, 8 weeks hands-on. From "A" School, trainees most often report to a NMCB or ACB. There recruits go through four-weeks of Expeditionary Combat Skills (ECS) which is also required for those who report to a Navy Expeditionary Combat Command. ECS is basic training in: map reading, combat first aid, recon, and other combat-related skills. Half of each course is spent on basic marksmanship to qualify with an M16 rifle#M16A3, M16 rifle and the Beretta M9, M9 service pistol. Those posted to Alfa Company of a NMCB may be assigned to a crew-served weapon: Mk 19 grenade launcher, MK 19 40mm grenade launcher, the M2 Browning, .50-caliber machine gun, or the M240 machine gun. Many reserve units still field the M60 machine gun. Seabees were last U.S. military to wear the U.S. Woodland camouflage uniform or the Desert Camouflage Uniform. They now have the Navy Working Uniform NWU Type III and use All-purpose Lightweight Individual Carrying Equipment, ALICE field gear. Some units, with the Marines, will use USMC-issue Improved Load Bearing Equipment (ILBE).

Marine Corps, Seabees outside the NCF
*When the 18th, 19th and 25th CBs were transferred to the Marine Corps they each were reduced by one company plus 1/5th of Hq Co to match the organization of a USMC battalion. B Co from the 25th CB and C Co from the 18th CB were used to form the 53rd CB. The other company was used to form the 121st CB.
*Due to Seabees being given advanced rank upon enlistment, enlisted Marines referred to construction battalions as "sergeant's battalions". USMC sergeants do not pull guard duty, so the ranked Seabees would not be assigned. The NCOs of the 18th wore USMC chevrons and not USN "crows" on their uniforms.
*USN insignia on USMC issue.
*Seabees were shore party for the Marines on Bougainville, Peleliu, Guam, Purata Island, Roi-Namur, Saipan, Iwo Jima, and Okinawa. The Marines deployed them as combat engineers at Cape Gloucester, Tarawa, and Tinian.
*The first Marines assigned to a CB were attached to CBD 1010 on Guam. The 2nd Separate Marine Engineer Battalion was next, assigned to the 27th NCR with two former USMC CBs; the 25th and the 53rd. In mid-August 1944 the 1st Separate Marine Engineer Battalion was assigned to the 30th NCR. Prior, 100 Marines were assigned to the 71st CB on Bougainville.

*In 1977, the U.S. Embassy in Moscow suffered a severe fire prompting the construction of a new one in 1979. At the construction site of the new embassy twenty to thirty Seabees were assigned to oversee 800 plus Russian construction workers. This prompted the Russians to embed bugs in construction materials prior to delivery to the construction site. The success of the KGB in bugging the new embassy only reinforced the State Department's need for the Seabees.

On 28 December 1941, Adm. Moreell requested authority to commission three Naval Construction Battalions. His request was approved on 5 January 1942 by Admiral Nimitz. The 1st HQ Construction Company was used to commission the 1st Naval Construction Detachment, which was assigned to Operation Bobcat. They were sent to Bora Bora

Concurrently, the other requested companies had been approved. BuDocks took Companies 2 & 3 to form the 1st Naval Construction Battalion at Charleston, South Carolina. HQ Companies 4 & 5 were used for the 2nd CB. All four companies deployed independently. CBs 3, 4, & 5 were deployed the same way. CB 6 was the first battalion to deploy as a Battalion.
Before all this could happen, BuDocks had to address the dual command issue. Naval regs stated unit command was strictly limited to line officer

. On 19 March 1942, Knox gave the CEC complete command of all NCF personnel. Almost 11,400 would become CEC during WWII with 7,960 doing CB service. Two weeks earlier, on 5 March all CB personnel were officially named "Seabees".
The first volunteers were tradesmen that received advanced rank for their trade skills. This resulted in the Seabees being the highest-paid group in uniform. To recruit these men, age and physical standards were waived up to age 50. Until November 1942 the average Seabee was 37, even so, all received the same physical training

ordered the Selective Service System to provide CB recruits. Enlistees could request CB service with a written statement certifying that they were trade qualified. This lasted until October 1943 when voluntary enlistment in the Seabees ceased until December 1944. By war's end, 258,872 officers and enlisted had served in the Seabees.

Advance Bases
The Office of Naval Operations created a code identifying Advance Base (AB) construction as a numbered metaphor for the size/type of base. That code was also used to identify the "unit" that would be the administration for that base. These were Lion, Cub, Oak and Acorn with a Lion being a main Fleet Base (numbered 1–6). Cubs were Secondary Fleet Bases 1/4 the size of a Lion (numbered 1–12). Oak and Acorn were the names given air installations, new or captured (airfield or airstrip). Cubs quickly gained status. The speed with which the Seabees could make one operational led the Marines to consider them a tactical component. Camp Bedilion shared a common fence-line with Camp Rousseau at Port Hueneme and was home to the Acorn Assembly and Training Detachment (AATD) As the war progressed, BuDocks realized that logistics required that Advance Base Construction Depots (ABCDs) be built and CBs built seven. When the code was first created, BuDocks foresaw two CBs constructing a Lion. By 1944 an entire Regiment was being used. The invasion of Okinawa took four Construction Brigades of 55,000 men. The Seabees built the infrastructure needed to take the war to Japan. By war's end CBs had, served on six continents, constructed over 300 bases on as many islands.

Marine Corps
USMC historian Gordon L. Rottman wrote "that one of the biggest contributions the Navy made to the Marine Corps during WWII was the creation of the Seabees". In exchange, the Corps would be influential upon the CB organization and its history. After the experience of Guadalcanal the Department of War decided that the Marines and Seabees would make all subsequent landings together. That arrangement led to numerous Seabee claims that they had landed first, even leaving signs on the beach asking the Marines "What took you so long?" The Seabees in the UDTs made an effort of this that their mates in the CBs approved of. When the first three CBs were formed the Seabees did not have a base of their own.

On Tinian the 6th Construction Brigade was attached to V Amphibious Corps.
* Two sections of CBMU 515 saw combat with the 22nd Marines on Guam.
*When the decision was made to construct Marine Corps Base, Camp Pendleton in 1942, BuDocks issued the main contracts to civilian contractors. However, the base project was so large that some smaller contracts were awarded to the Seabees, one of which was a Quonsent Camp for USMC instruction of Naval Construction Battalions in area 25(Vado del Rio). Seabees were also involved in the construction of Camp Del Mar in area 21 and erected a temporary construction camp close by while they were assigned.
When the war ended the Seabees had a unique interservice standing with the U.S. Marine Corps. Seabee historian William Bradford Huie wrote "that the two have a camaraderie unknown else-wheres in the U.S. military". Even though they are "Navy" the Seabees adopted USMC fatigues with a Seabee insignia in place of the EGA. At least 10 CB units incorporated USMC insignia into theirs. Admiral Moreell wrote, tongue in cheek, that the Marines were the best fighting men in the Pacific, but one had to serve 90 days with the Seabees to qualify to as a "Junior Bee".
Naval Combat Demolition Units
In early May 1943, a two-phase "Naval Demolition Project" was ordered by the Chief of Naval Operations "to meet a present and urgent requirement" for the invasion of Sicily. Phase-1 began at Amphibious Training Base (ATB) Solomons, Maryland with the creation of Operational Naval Demolition Unit # 1. Six Officers led by Lt. Fred Wise CEC and eighteen enlisted reported from Camp Peary dynamiting and demolition school. Seabees called them "Demolitioneers".
Naval Combat Demolition Units (NCDUs) consisted of one junior CEC officer, five enlisted, and were numbered 1–216. After that first group had been trained, Lt. Commander Draper Kauffman was selected to command the program. It had been set up in Camp Peary's "Area E"(explosives) at the dynamiting and demolition school. Between May and mid-July, the first six NCDU classes graduated at Camp Peary. While the program was at Camp Peary the men were given head-of-the-line privileges at the mess hall. The program was moved to Fort Pierce where the first class began mid-July. Despite the move, Camp Peary remained Kauffman's primary recruit center. "He would go back to the dynamite school, assemble the (Seabees) in the auditorium and say, ''"I need volunteers for hazardous, prolonged and distant duty."'' Fort Pierce had two CB units assigned, CBD 1011 and CBMU 570. They were tasked with the construction and maintenance of obstacles needed for demolition training.
The invasion of Normandy had 34 NCDUs. When the first ten arrived in England they had no CO. Lt. Smith (CEC) assumed the role, splitting them up to train with the 146th, 277th and 299th Combat Engineers. As more NCDUs arrived they did the same, with 5 combat engineers attached to each NCDU. Group III (Lt. Smith) did research and development and is credited with developing the Hagensen Pack. NCDUs had a 53% casualty rate at Normandy. Four from Utah beach later took part in Operation Dragoon.
With Europe invaded, Admiral Turner requisitioned all available NCDUs from Fort Pierce for integration into the UDTs for the Pacific. That netted him 20 NCDUs that had received Presidential Unit Citations and another 11 that had gotten Navy Unit Commendations. Prior to Normandy 30 NCDUs had embarked to the Pacific and another three had gone to the United States Eighth Fleet, Mediterranean. NCDUs 1–10 were staged at Turner City on Florida Island in the beginning of 1944. NCDU 1 was briefly in the Aleutians in 1943. The first NCDUs in combat were 4 and 5 with the 4th Marines on Green Island, Papua New Guinea and Emirau Island. Later, NCDUs 1–10 were combined to form the short-lived UDT Able. NCDUs 2, 3, 19, 20, 21 and 24 were assigned to MacArthur's 7th Amphibious Force and were the only NCDUs remaining at the war's end.

Underwater Demolition Teams (UDT)s
Prior to Operation Galvanic and Tarawa, V Amphibious Corps had identified coral as an issue for future amphibious operations. RADM Richmond K. Turner, Kelly Turner, commander V Amphibious Corps had ordered a review to get a grip on the problem. VAC found that the only people having any applicable experience with the material were men in the Naval Construction Battalions. Lt. Thomas C. Crist, of CB 10, was in Pearl Harbor from Canton Island where he had been in charge of clearing coral, coral heads. His being in Pearl Harbor was pivotal in Underwater Demolition Team, UDT history. While there he learned of the Adm. Turner's interest in coral blasting and met with him. The Admiral tasked Lt. Crist to develop a method for blasting coral under combat conditions and putting together a team to do it. Lt. Crist started by getting men from CB 10, but got the remainder from the 7th Construction Regiment. By 1 December 1943 he had close to 30 officers and 150 enlisted at Waipio Amphibious Operating Base on Oahu.
In November the Navy had a hard lesson with coral and tides at invasion of Tarawa, Tarawa. It prompted Adm. Turner to request the creation of nine Underwater Demolition Teams to address those issues. Six teams for VAC in the Central Pacific while the other three would go to III Amphibious Corps in the South Pacific. UDTs 1 & 2 were formed from the 180 men Lt. Crist had staged. Seabees make up the majority of the men in teams 1–9, 13 and 15. How many Seabees were in UDTs 10 and 12 is not listed, for UDT 11 they composed 20% of the team.
UDT officers were mainly CEC. UDT 10 had 5 officers and 24 enlisted originally trained as OSS Operational Swimmer Groups, Maritime Unit: Operational Swimmer Group II, but the OSS was not allowed to operate in the Asiatic-Pacific Theater, Pacific Theater. Adm. Nimitz needed swimmers and approved their transfer from the OSS to his control. The MU men brought with the swimfins they had trained with and the Seabees made them a part of UDT attire as quickly as the Navy Supply Corps, Supply dept. could get them. In the Seabee dominated teams the next largest group of UDT volunteers came from the joint Army-Navy Scouts and Raiders school that was also in Fort Pierce. Additional volunteers came from the Explosive ordnance disposal (United States Navy), Navy's Bomb disposal School, Marine Corps and U.S. Fleet.
The first team commanders were Cmdr. E.D. Brewster (CEC) UDT 1 and Lt. Crist (CEC) UDT 2. Both Teams were "provisional" totaling the 180 men Lt Crist had put together from the 7th NCR. Those men were put through five weeks of training by a United States Marine Corps Amphibious Reconnaissance Battalion, Marine Corps Amphibious Reconnaissance Battalion. They wore fatigues, life-vests and were expected to stay in their rubber boats like the NCDUs. At Kwajalein Adm.Turner ordered daylight reconnaissance, recon. It was apparent to the Seabees that staying in the boats would not get the Admiral the military intelligence, intel he wanted. Cmdr. Brewester's men all wore swim trucks under their fatigues. Ensign Lewis F. Luehrs, and Charp. Bill Acheson spent 45 minutes in the water in broad daylight and were the first team members recovered. Still wet and in their trunks they reported directly to Adm. Turner. He concluded what they had done was the only way to get accurate intelligence on submerged obstacles and conveyed that opinion to Chester Nimitz, Adm. Nimitz. At Engebi Cmdr. Brewster was wounded. The success of UDT-1 not following USMC Recon protocol rewrote the UDT mission model and training regimen. Ens. Luehrs and Charp. Acheson were each awarded a Silver Star for their initiative while unintentionally creating the UDT "naked warrior" image. Diving masks were uncommon in 1944 and some men had tried using goggles at Kwajalein.Naked Warriors, Cdmr. Francis Douglas Fane USNR (Ret.), St. Martin's Press, New York, 1996, p. 828 Diving masks were a rare item in Hawaii so Lt. Crist and CB Chief Howard Roeder had requested supply get them. A fortuitous observation by one of the men spotted a magazine advertisement for diving masks. A priority dispatch was made to the States that appropriated the store's entire stock. The UDTs adopted goggles independent of the OSS. When UDTs 1 and 2 returned to Hawaii Chief Acheson and three other UDT Officers were transferred to the 301st dredging CB. The 301st had 12 dredges saving Teams from blasting channels, but needed divers to get the job done. Ensign Leuhrs made Lt. and was a member of UDT 3 until he was made XO of team 18. Commander Brewster's purple heart got him out of the UDTs and elevated to Commander 7th NCR instead of back to CB 10.
Adm. Turner also requested the formation of a Demolition Training Center at Kihei. It was approved. The actions of UDT 1 provided the training model, making UDT training distinctly different from Fort Pierce's NCDU program. Lt. Crist was briefly the first training officer and emphasized swimming and recon until he was made CO of UDT 3. When UDT 3 returned from Leyte in the fall of 1944 it became the school instructors with Lt. Crist again OIC of training. The classes now included: Night operations (military), night ops, weapons, bivouacking, small Military tactics, unit tactics, along with coral and lava blasting. In April 1945, team 3 was sent to Fort Priece to instruct there. Lt. Crist was promoted to Lt. Cmdr. and sent back to Kihei. Team 3 would train teams 12–22. UDT 14 is called the first "all fleet team" even though it had Seabees from Team Able and the CO and XO were both CEC. UDT 15 was the last team formed of NCDUs. Teams 12–15 were sent to Iwo Jima. Three cleared the shoreline for five days, D+2-D+7. After July 1944 new UDTs were only USN. In 1945, CBMU 570 was tasked to the UDT coldwater training center at ATB Oceanside, CA.
On Guam team 8 requested permission to build a base. It was approved by AdComPhibsPac, but disapproved by Island Command. Team 8 turned to the CBs on the island and got everything needed. Coral paving got placed the night before Admiral Nimitz inspected, giving teams 8 & 10 a glowing review.
By V-J day 34 teams had been formed.
Teams 1–21 saw actual deployment with the Seabees providing over half of the men in those teams. The Navy did not publicize the existence of the UDTs until post-war and when they did they gave credit to Lt. Cmdr. Kauffman and the Seabees. During World War II the Navy did not have a rating for the UDTs nor did they have an insignia. Those men with the CB rating on their uniforms considered themselves Seabees that were doing underwater demolition. They did not call themselves "UDTs" or "Frogmen", but rather "Demolitioneers" reflecting where Lt. Cmdr. Kauffman had recruited them from, the CB dynamiting and demolition school.
UDTs had to be of standard recruiting age, Seabees older could not volunteer. Mid-year 1945, in preparation for the cooler waters around Japan, a cold water training center was created. With it came a more demanding physical examination, physical. Team 9 lost 70% of the team to this change.
Postwar, MCB 7 was tasked with projects at the UDT training facility on St. Thomas, Virgin Islands

Cold War
When World War II ended the Cold War began. Seabee service during this period supported a broad spectrum of the national interest; nuclear testing, two wars, embassy security, space race, CIA, military communications, international relations, pure science, and Camp David.Postwar interlude: Siberia-China
On V-J-Day CB 114 was in the Aleutians. In September 1945 the battalion sent a detachment to the USSR to build a Fleet Weather Central. It was located outside Petropavlovsk-Kamchatsky on the Kamchatka Peninsula. The original agreement gave the Seabees 3 weeks to complete the base. Upon arrival the Russians told them they had 10 days and were amazed it was done in 10. It was one of two that Stalin agreed to. V-J-Day brought about Operation Beleaguer and the repatriation of the Japanese Army from China. Elements of the 33rd CB Regiment were involved: CBs 83, 96, 122 and 32nd Special. These units landed at Tsingtao and Tangku in November 1945 attached to the 6th Marine Division. CB 42 and A Co. 33rd Special landed at Shanghai with Naval Advance Base Unit 13. With the war over, the ongoing discharge men eligible left only enough for one CB and the two CB Specials. The men were consolidated in the 96th with the other CBs decommissioned. In December the 96th started airfields at Tsingtao and Chinwangtao in support of III Marine Amphibious Corps operations. May 1946 CB III Marine Amphibious Corps was ordered to inactivate the 96th CB on 1 August. The 96th was transferred to the 4th Marines, 1st Marine Division and deactivated from them.Nuclear tests
In early 1946 the 53rd NCB was deployed with Operation Crossroads for the nuclear testing at Bikini Atoll. It was designated Task Unit TU 1.8.6. 53's project list included observation, instrument and communication towers, radio beacons, seismic huts, photo reference crosses, general base and recreational facilities, as well as dredging the lagoon. In addition, recreational facilities were constructed on Japtan Island for the ships crews of the Operation. The Battalion also assisted the relocation of the natives. They disassembled both the Community center and church for reassembly on Rongerik Atoll. In August the battalion was decommissioned with men transferred to CBD 1156 that was then commissioned on Bikini. The TU 1.8.6 designation transferred to the CBD. CBD 1156 remained for nine days after the second test.
UDT 3 was designated TU 1.1.3 for the operation. On 27 April 1946, seven officers and 51 enlisted embarked at CBC Port Hueneme for Bikini. Their assignment was to retrieve water sample (material), samples from ground zero of the Baker blast. In 1948, the displaced bikinians put in a request that a channel to the island Kili Island, Kili where they had been relocated be made. This was given to the Seabee detachment on Kwajelin who requested UDT 3 assist.
The 121st CB was decommissioned in December and re-designated CBD 1504. In January 1947 CBs 104 and 105 were reactivated. The 30th NCR was home-ported on Guam composed of CBDs 1501-13 and NCB 103. In 1949, the 103rd was made a Mobile Construction Battalion (MCB) while CBs 104 and 105 were made Amphibious Construction Battalions(ACBs). From 1949 until 1968 CBs were designated MCBs. In 1949, MCB 1 was reactivated at Naval Amphibious Base Little Creek, VA. In June 1950 the NCF totaled a few thousand.
Korean War
The outbreak of the Korean War led to a call-up of 10,000 from the Seabee Reserve. Seabees landed at Battle of Inchon, Inchon during the assault, installing causeways dealing with enormous tides and enemy fire. Their actions there and elsewheres underscored the necessity of having CBs. During that war the authorized size of a CB was 550 men. When the truce was declared there was no CB demobilization as there had been at the end of World War II.
During the Korea, the U.S. realized the need of an air station in the region. Naval Air Station Cubi Point, Cubi Point in the Philippines was selected. Civilian contractors were approached for bids. After seeing the Zambales Mountains and the maze of jungle, they claimed it could not be done. The Navy then turned to the Seabees. The first to arrive was CBD 1802 to do the surveying. Naval Mobile Construction Battalion Three, MCB 3 arrived on 2 October 1951 to get the project going and was joined by MCB 5 in November. Over the next five years, MCBs 2, 7, 9, 11 and CBD 1803 all contributed to the effort. They leveled a mountain to make way for a nearly runway. NAS Cubi Point turned out to be one of the largest earth-moving projects in the world, equivalent to the construction of the Panama Canal. Seabees there moved of dry fill plus another 15 million that was hydraulic fill. The $100 million facility ($ in dollars) was commissioned on 25 July 1956, and comprised an air station and an adjacent pier that was capable of docking the Navy's largest carriers.
Seabee Teams
The World War II precursor to Seabee teams was the PT Advance base Detachment of the 113th CB. Each man was cross-trained in at least three trades with some qualified as corpsmen and divers. During Vietnam the requirement of being skilled in three trades was continued. The first Seabees referred to as "Seabee Teams" were CBDs 1802 and 1803. They were followed by Detachments Able and Baker. The U.S. State Department learned of the teams and concluded they could have a Cold War purpose. They could be U.S. "Good Will Ambassadors" to third world countries to counter the spread of Communism, a military version of the Peace Corps. These 13-man teams would construct schools, drill wells or build clinics creating a positive image for the U.S. They were utilized by the United States Agency for International Development and were in S.E. Asia by the mid-1950s. Then in the early sixties, the U.S. Army Special Forces were being sent into rural areas of South Vietnam to develop a self-defense force to counter the Communist threat and making use of the Seabee teams at these same places made sense to the CIA. To start, twelve "Seabee teams, with Secret Clearances, were sent with the Army's Special Forces in the CIA funded Civilian Irregular Defense Group program (CIDG)"Commander Naval Construction Battalion U.S. Pacific Fleet, Tân Sơn Nhất, Republic of Vietnam, Completion Report 1963–1972./ref> in the years 1963–1965. By 1965 the U.S. Army had enough engineers in theater to end Seabee involvement with Special Forces. At first teams were called Seabee Technical Assistance Teams (STAT) and were restricted to two in theater at a time. Teams after STAT 1104 were renamed Seabee Teams and by 1969 there were 17 in theater. As a military force Seabee Teams received many awards for heroism. Teams were sent to other nations as well. The Royal Thai government requested STATs in 1963 and ever since the Seabees have continued to deploy teams. Construction Civic Action Details or CCAD CCADs or "See-Kads" are larger civic action units of 20–25 Seabees with the same purpose as Seabee Teams. The CCAD designation is not found in the record prior to 2013.
Camp David
Camp David is officially known as Camp David, Naval Support Facility Thurmont, as it is technically a military installation. The base is staffed by the CEC, Seabees, and Marines. "In the early 1950s, Seabee BUs, UTs and CEs took over routine maintenance of the base and additional rates were added for administrative functions. Today Seabees still man the base public works and see that the Groundskeeping, grounds are in an impeccable condition." "Selectees undergo a single scope Background check, background investigation to determine if they qualify for a Security clearance, Top Secret Sensitive Yankee White (YW) clearance. All personnel in Presidential support activities are required a "Yankee White" security clearance. The tour lasts 36 months." When the base has a larger construction project a Construction Battalion from the fleet can be tasked. NMCBs Naval Mobile Construction Battalion 5, 5 and Naval Mobile Construction Battalion 133, 133 have drawn these assignments.Antarctica: Science
Operation Highjump
In December 1946, 166 Seabees sailed from Port Hueneme on the USS Yancey and USS Merrick assigned to Operation Highjump. They were part of Admiral Richard E. Byrd's Antarctic expedition. The U.S. Navy was in charge with "Classified" orders "to do all it could to establish a basis for a (U.S.) land claim in Antarctica"."Operation Highjump" ''Air & Space Magazine'', July 2007, Smithsonian Institution, Washington, DC/ref> The Navy sent the Seabees to do the job starting with the construction of Little America (exploration base) IV as well as a runway for aerial mapping flights.

making Antarctica an annual deployment site. Their task was the construction and maintenance of scientific bases for the National Science Foundation. The first "wintering over" crew included 200 Seabees. They cleared an ice runway at McMurdo Sound, Mcmurdo for
the advance party of Deep Freeze II to fly to South Pole Station. Naval Mobile Construction Battalion 1, MCB 1 was assigned for Deep Freeze II.
Antarctica added to the Seabee's list of accomplishments:
*Tractor train Traverse (climbing), traverses covering hundreds of miles.
*Bases built: McMurdo Station, South Pole Station, Byrd Station, Palmer Station, Siple Station, Ellsworth Station, Brockton Station (Antarctica), Brockton Station, Eights Station, Plateau Station, Hallett Station, and Little America (exploration base), Little America IV and Little America V
*MCB 1s construction of a nuclear power plant which got them a Navy Unit Commendation.
*NMCB 71s construction of a Buckminster Fuller Geodesic dome at So. Pole Station. It became a symbolic icon of the United States Antarctic Research Program (USARP).

Vietnam War
Seabees were in Vietnam twice in the 1950s. First in June 1954, as elements of Operation Passage to Freedom and then two years later to map and survey the nation's roads. Seabee teams 501 and 502 arrived January 1963 and are recorded as the first Seabees of the Vietnam War
The Vietnam War (also known by other names) was a conflict in Vietnam, Laos, and Cambodia from 1 November 1955 to the fall of Saigon on 30 April 1975. It was the second of the Indochina Wars and was officially fought between North Vietnam a ...
. They went to Dam Pau and Tri Ton to build Special Forces camps. In 1964, ACB 1 was the first CB in the theatre. In 1965, Marines and Seabees made an amphibious landing at Chu Lai and entire Naval Construction Regiments followed.Seabees in Action in Vietnam, Naval Facilities Engineering Command, U.S. GPO 1968 O-323-015. Seabees supported the Marines at Khe Sanh and Chu Lai Base Area, Chu Lai combat bases in addition to building numerous aircraft-support facilities, roads, and bridges. Every mile of road improved equated to 100' of bridgedeck constructed. They also worked civic action projects throughout the country. In June 1965, Construction Mechanic 3rd Class Marvin Glenn Shields, Marvin G. Shields of Seabee Team 1104 was at the Battle of Dong Xoai. He was posthumously awarded the Medal of Honor and is the only Seabee to receive the award. Seabee Teams were deployed throughout the War. They typically built schools, clinics, or drilled wells. In 1966, Seabees repaired the airfield at Khe Sanh Combat Base, Khe Sahn laying aluminum matting covering 3,900'x60' in four days. General Westmoreland "called it one of the most outstanding military engineering feats of the war." MCB 4 had a det at Con Thien
Con Thien (Vietnamese: Cồn Tiên, meaning the "Hill of Angels") was a military base that started out as a U.S. Army Special Forces camp before transitioning to a United States Marine Corps combat base. It was located near the Vietnamese Dem ...
whose actions were a near repeat of Battle of Đồng Xoài, Dong Xoai.
In 1968, the Marine Corps requested that the Navy make a change. The Marines were using "MCB" for Marine Corps Base while the Navy was using "MCB" for Mobile Construction Battalion, it was causing confusion in logistics. The Navy agreed and added "Naval" to MCB creating the NMCBs that now exist. During that year the 30th NCR had five battalions in the Da Nang area and two at Chu Lai. The 32nd NCR had three battalions tasked near Phu Bai and one at Dong Ha. In May 1968 two reserve battalions RNMCB 12 and 22 were activated, bring the total number of battalions in Vietnam to 21. Both ACBs were in theater as well as CBMUs 301 and 302. In 1968, NMCB 10 drew an atypical Seabee "task" supporting the 101st Airborne. It happened again in 1969 when CBs 10, 40 and 121 sent EOs to Fire base Fury. During 1969 the number of Seabees in theater reached 29,000, from there their draw-down began. The last battalion withdrew late 1971 with the last Seabee teams out a year later. When it was over they had sent 137 Seabee teams, built 15 CB camps, and deployed 22 battalions. Construction Battalion Maintenance Unit 302, CBMU 302 became the largest CB ever at over 1400 men and was homeported at Cam Rahn Bay. On 23 April 1975 it was announced that U.S. involvement in Vietnam was over.
That day CB 4 started construction of a temporary camp for Operation New Life on Guam. In seven days 2,000 squad tents were erected and numbered 3,500 when done.
During Vietnam the Seabees had a few uniform variations. One was the stenciling of unit numbers across the back of the field jacket M-65. Another was the collar and cover devices for enlisted E4-E6. The Navy authorized that the "crow" be replaced by the rating insignia of each trade. Nametags were another, they started out white with a multicolored seabee. In 1968, the USMC OD green pattern was copied. The NAVCATs became the only Seabees to ever be authorized to wear a shoulder patch.
NAVCATs Naval Construction Action Teams
CBMU 302 had 23 NAVCATS(Naval Construction Action Teams) total with 15 the most active at one time. Teams were numbered 1-23. They were Vice Admiral Elmo Zumwalt's expansion of the Seabee Team concept. He submitted it in November 1968 to General Creighton Abrams commander of Military Assistance Command, Vietnam.
Agent Orange
Many Seabees were exposed to the defoliant herbicide while in Vietnam. NCBC Gulfport was the largest storage depot in the United States for agent orange. From there it was shipped to Vietnam.Agent Orange clean at Navy Seabee base is the focus at public meeting, reported by Natalie Campen, WLOX TV, Gulfport, MS, July 9, 2013 at 3:04 PM CDT/ref> In 1968, the NCBC received 68,000 barrels to forward.''The History, Use, Disposition and Environmental Fate of Agent Orange'', Chapt 7: Monitoring Studies of Former Agent Orange Storage Sites in Mississippi and Johnston Island, Alvin L. Young, Springer Publishing, 2008
/ref> Long term barrel storage began in 1969. That lasted until 1977. The site covered 30 acres and was still being cleaned up in 2013.
Space race: NASA/Tektite I
In 1960, a MCB 10 detachment built a Project Mercury telemetry and Ground station, ground instrumentation station on Canton island. On 28 January 1969 a detachment of 50 men from Amphibious Construction Battalion 2 plus 17 Seabee divers began installation of the Tektite habitat in Great Lameshur Bay at Lameshur, U.S. Virgin Islands. The Tektite program was funded by NASA and was the first scientists-in-the-sea program sponsored by the U.S. government. The Seabees also constructed a 12-hut base camp at Viers that is used today as the Virgin Islands Environmental Resource Station. The project was a by product of the space race. It caused the U.S. Navy to realize the need for a permanent Underwater Construction capability that led to the formation the Seabee Underwater Construction Teams". At present NASA is working on the Human mission to Mars, Moon to Mars program. In 2015, ACB 1 was involved in moving the Orion's Boilerplate (spacecraft), Boilerplate Test Article (BTA). ACB 1 was tasked in August 2019 in a test recovery exercise of the Orion spacecraft. ACB 2 was put through the same task a year later in August 2020.CIA and Naval Intelligence/Communication support
* After the Seabees left Camp Peary the CIA moved into the base and now refer to it as "the Farm". * During World War II NAS Tanapag, Saipan was a "major propaganda site of the Office of War Information" (OWI). In 1947, CBD 1510 began maintaining NAS Tanapag for the NTTU (Naval Technical Training Unit).Cold War covert activities on Saipan, elsewhere in the region, Posted on Dec 21 2004, Saipan Tribune/ref> In 1948, CBD 1510's men were transferred to CBD 1504 when it was replacing CB 121 as island Public Works. That year the CIA created the NTTU as a "cover" and made access highly restricted to the base. The CIA station had Capitol Hill, Saipan, Capitol Hill constructed to administer its operations at a cost of $28 million. The station covered the northern half of Saipan including, East Field (Saipan), Kagman Field, Marpi Point Field, and the four radio towers. "Brig. Gen. Edward G. Lansdale, Pentagon expert on guerrilla warfare, shared with Gen. Maxwell D. Taylor, President Kennedy's military adviser, on "Resources for Unconventional Warfare in SE. Asia."....that the "CIA maintains a field training station on the island of Saipan ... the installation is under Navy cover and is known as the Naval Technical Training Unit. The primary mission of the Saipan Training Station is to provide physical facilities and competent instructor personnel to fulfill a variety of training requirements including Espionage, intelligence tradecraft, communications, counter-intelligence and psychological warfare techniques. Training is performed in support of CIA activities conducted throughout the Far East area." The Seabees cease listing the Public Works assignments at NAS Tanapag in 1953 while the CIA remained until 1962. However, MCB 9 deployed to Saipan in 1954 with one of their projects being the up-grading of the Public Works shops. MCB 10 Det Bravo deployed to Saipan from July 1957 until February 1958 with projects unlisted.
* A year before the Bay of pigs and Cuban Missile Crisis the CIA took a "top secret" urgent/immediate project to the Seabees.Radio Swan: Seabees Part of Cold War History, Seabee Magazine online, Kenneth Van Belkum, Cmdr. CEC (retired), OIC of Det. Tango, Seabee Museum, Port Hueneme, CA/ref> The agency wanted two 220' radio towers with a supporting airstrip, dock, and quonsets erected on Swan Islands, Honduras, Swan Island, built asap, with no construction plans for the Seabees. The station would be independent-self sufficient. Det Tango of MCB 6 was given the project. LSTs 1046 and 1056 delivered men and materials from CBC Quonset Point. The Seabees had the CIA's "Radio Swan" on the air in short order. Naval Intelligence: NAVFACs The Navy built 22 Naval Facilities (NAVFACs) for its Sound Surveillance System (SOSUS) to track Soviet submarines. They were in service 1954–79 with Seabees staffing all the Public works. In the 1980s the number of tracking stations was halved with the advent of the Integrated Underwater Surveillance System (IUSS). The NAVFACs were decommissioned by further advances in technology, the end of the Cold War and disclosures by John Anthony Walker, John Walker to the Soviets. The Seabees have also been tasked building Naval Communication facilities. One at Nea Makri Greece was built by MCB 6 in 1962 and upgraded by NMCB 133. United States Naval Communications Station Sidi Yahya El Gharb, Naval Comm Station Sidi Yahya was first built in World War II another is NavCommSta Guam. It started out on the island as the Joint Communications Agency (JCA) in 1945.
Naval Support Unit: Department of State/Embassy security
In 1964, at the height of the Cold War, Seabees were assigned to the State Department because listening devices were found in the Embassy of the United States in Moscow. Those initial Seabees were "Naval Mobile Construction Battalion FOUR, Detachment November". The U.S. had just constructed a new embassy in Warsaw. After what had been found in Moscow Seabees were dispatched and found many "bugs" there also. This led to the creation of the Naval Support Unit in 1966 as well as the decision to make it permanent two years later. That year William Darrah, a Seabee of the support unit, is credited with saving the U.S. Embassy in Prague, Czechoslovakia from a potentially disastrous fire. In 1986, "as a result of reciprocal expulsions ordered by Washington and Moscow" Seabees were sent to "Moscow and Leningrad to help keep the embassy and the consulate functioning".
The Support Unit has a limited number of special billets for select NCOs, E-5 and above. These Seabees are assigned to the Department of State and attached to Diplomatic Security. Those chosen can be assigned to the Regional Security Officer of a specific embassy or be part of a team traveling from one embassy to the next. Duties include the installation of alarm systems, CCTV cameras, electromagnetic locks, safes, vehicle barriers, and securing compounds. They can also assist with the security engineering in sweeping embassies (electronic counter-intelligence). They are tasked with new construction or renovations in security sensitive areas and supervise private contractors in non-sensitive areas. Due to Diplomatic protocol the Support Unit is required to wear civilian clothes most of the time they are on duty and receive a supplemental clothing allowance for this. The information regarding this assignment is very scant, but State Department records in 1985 indicate department security had 800 employees, plus 1,200 Marines and 115 Seabees. That Seabee number is roughly the same today.
Cold War winds down
As the Cold War wound down, new challenges and changes came for the Seabees starting with the increased incidence of terrorism. This was in addition to ongoing Seabee support missions for USN/USMC bases worldwide. Cold War Facilities still required support, like the UGM-27 Polaris, Polaris and UGM-73 Poseidon, Poseidon submarines at Holy Loch, Naval Station Rota, Spain, Rota. In 1971, the Seabees began the huge project on Naval Support Facility Diego Garcia, Diego GarciaSeabee History: After Vietnam, Published: 16 Apr 2015, NHHC, Official U.S. Navy web site/ref> in the Indian Ocean. It was completed in 1987 at a cost of $200 million. With the extended construction timeline, it is difficult to inflation-adjust that cost into today's dollars. The complex accommodates the Navy's largest ships and cargo planes. The base served as a staging facility for Operations Desert Shield and
Desert Storm
The Gulf War was a 1990–1991 armed campaign waged by a 35-country military coalition in response to the Iraqi invasion of Kuwait. Spearheaded by the United States, the coalition's efforts against Iraq were carried out in two key phases: ...
. Additionally, Seabees were also tasked upgrading and expanding Naval Air Station Sigonella, Sicily for the United States Sixth Fleet.
In 1983, a truck bomb demolished the 1983 Beirut barracks bombings, Marine's barracks in Beirut, Lebanon. From the Beirut International Airport Druze militia artillery harassed the Marines. NMCB-1 was in Rota and sent its AirDet to construct bunkers for the Marines. EO2 Kirt May became the first Seabee post-Vietnam to receive a Purple Heart while on this mission.
CN Carmella Jones became the first female Seabee when she cross-rated to Equipment Operator during the summer of 1972.
International terrorism
The Cold war did not end until 1991 and 9/11 was further off yet, but SW2 Robert Stethem was executed by the Lebanese Shia Islam, Shia militia Hezbollah when they hijacked TWA Flight 847 in 1985. Stethem was a Navy diver (United States Navy), diver in UCT 1. The Navy named in his honor. On 24 August 2010, during a shipboard ceremony, Stethem was posthumously honored to the rank of Steelworker (United States Navy), Master Chief Constructionman (CUCM) by the Master Chief Petty Officer of the Navy and given the Prisoner of War Medal.Persian Gulf War
Over 5,000 Seabees served in the Gulf War. In August 1990 the 1st Marine Expeditionary Force (I MEF) was assigned NMCBs 4, 5, 7, and 40.Seabee History: After Vietnam, Apr 2015, NHHC, Official USN web site/ref> The first Seabees in theater were a Det from ABC 1, followed by a Det from ACB 2 and then CBUs 411 and 415. Mid September Air-Dets from the four battalions deployed to construct air fields for Marine Air Groups (MAG) 11, 13, 16, and 25 of the 3rd Marine Air Wing. NMCB 7 was the first Battalion to arrive. Camp Nomad was a NMBC-74 project at Ras Al Mishab for MAG 26. Camps were constructed for both the 1st and 2nd Marine Divisions as well as Hq complexes for MEF I and II. In Saudi Arabia, Seabees built numerous camps, galleys, runways, aprons, helicopter, helo zones, plus two 500-bed Fleet Hospitals near Jubail, Al-Jubayl. The 3rd NCR was activated to provide a command echelon. NMCBs 24 and 74 also deployed in support of the Marines.
Iraq, Afghanistan, and the War on Terror
Seabees deployed in both initial invasions of the War in Afghanistan (2001-2021), Afghanistan War and War in Iraq, Iraq War. All active and reserve NMCBs and NCRs were deployed to building to work on civil infrastructure.Seabee History: The US Navy in Operation Enduring Freedom, 2001–2002: 18 Aug. 2017, NHHC, Official U.S. Navy web site/ref> One of the most visible tasks assigned to the NCF was the removal of statues of Saddam Hussein in Baghdad. In Afghanistan, the Seabees' main task was the construction of multiple forward operating bases. NMCB 133 deployed to FOB Camp Rhino and help build Kandahar Airfield where a detention facility was constructed as well. O Since 2002, Seabees have provided civic action support in the Philippines, most notably near Abu Sayyaf's jungle training area in the southern Philippines. Seabees work with Army, Marines, and Air Force under the Joint Special Operations Task Forcem -Philippines. Seabees have supported the War on Terror ever since the invasion with numerous deployments over the years.

At present, there are six active-duty Naval Mobile Construction Battalions (NMCBs) in the United States Navy, split between the Pacific Fleet and the Atlantic Fleet. 30th Naval Construction Regiment is located on Guam. Naval Construction Battalion Center Port Hueneme Ca. is homeport to the Regiment's battalions. * Naval Mobile Construction Battalion 3 * Naval Mobile Construction Battalion 4 * Naval Mobile Construction Battalion 5 22nd Naval Construction Regiment is stationed at Naval Construction Battalion Center (Gulfport, Mississippi) the homeport to the Atlantic fleet CBs. * Naval Mobile Construction Battalion 1 * Naval Mobile Construction Battalion 11 * Naval Mobile Construction Battalion 133 NCF Reserve From the 1960s through 1991, reserve battalions were designated as "Reserve Naval Mobile Construction Battalions" (RNMCBs). After 1991 "Reserve" was dropped with the integration of reserve units within the NCF making all battalions NMCBs * Naval Mobile Construction Battalion 14, HQ Gulfport, MS. detachments in five states and Puerto Rico. * Naval Mobile Construction Battalion 18, HQ Port Hueneme, CA., detachments in six states and Guam. * Naval Mobile Construction Battalion 22, HQ Port Hueneme, CA. detachments in five states. * Naval Mobile Construction Battalion 25, HQ Port Hueneme, CA. detachments in six states. * Naval Mobile Construction Battalion 27, HQ Gulfport, MS. detachments in seven states. Detachment: A construction crew that is "detached" from the battalion's "main body" deployment site. The size is determined by the project scale and timeline. Battalion: The battalion is the basic NCF unit with a HQ Company plus four Construction Companies: A, B, C, & D. CBs are organized to function as independent self sufficient units. Regiment: Naval Construction Regiments (NCRs) provide a higher echelon command to three or four CBs operating on close proximity. Naval Construction Groups 1 and 2: In 2013, Seabee Readiness Groups (SRGs) were decommissioned, and re-organized as NCG-1 and NCG-2. They are regimental-level command groups tasked with administrative and operational control of CBs, as well as conducting pre deployment training for all assigned units. NCG-2 is based at CBC Gulfport while NCG-1 is at CBC Port Hueneme. Seabee Engineer Reconnaissance Team (SERTs) SERTs are the Marine expeditionary unit (special operations capable), Special operations capable element of the NCF developed by the First Naval Construction Division (1st NCD) in Operation Iraqi Freedom. They are intended to provide engineering assessments in the field in support of the United States Marine Corps Reconnaissance Battalions. A team has two CEC officers and eight enlisted Seabees, augmented by additional personnel as needed. A team has three elements: liaison, security, and reconnaissance. The liaison (LNO) element has an officer and two communications specialists responsible for communicating the assessments and intelligence. Reconnaissance has the other officer, who is the Officer-in-Charge (OIC), a Builder (US Navy), BU or Steelworker (US Navy), SW chief petty officer, cpo with bridge construction experience. The team has a corpsman or medically trained member, the remainder are selected for being the most qualified in their trade. All are required to have the Seabee Warfare pin. In 2013, 1st Naval Construction Division along with SERT's were decommissioned. Today, UCTs performance demonstrate the SERT concept for NECC.Seabees outside the NCF
Amphibious Construction Battalions (PHIBCBs) ACBs (or PHIBCB) were preceded by the pontoon assembly CBs formed during World War II. On 31 October 1950, MCBs 104 and 105 were re-designated ACB 1 and ACB 2, and assigned to Naval Beach Groups. ACBs report to Surface warfare, surface U.S. Navy type commands#Commander, Naval Surface Forces, TYCOMs. Additionally, in an ACB half the enlisted are a construction rate while the other half are fleet. Construction Battalion Maintenance Units When during World War II these units had 1/4 the personnel of a CB. Their task was to assume maintenance of bases once CBs had completed construction. Today, CBMU's provide public works support at Naval Support Activities, Forward Operating Bases, and Fleet Hospital/Expeditionary Medical Facilities during wartime or contingency operations for a Marine Expeditionary Force (MEF), Marine Expeditionary Group (MEG), or NSW. They also provide disaster recovery support to Naval Regional Commanders in Contiguous United States, CONUS. * CBMU 202 Naval Base Little Creek, VA **det Jacksonville * CBMU 303 Navy Expeditionary Combat Force, Naval Base San Diego, Ca. **det Port Hueneme **det Pearl Harbor NAVFAC Engineering & Expeditionary Warfare Center Ocean Facilities Department.Ocealoopn Facilities Department, NAVFAC Engineering & Expeditionary Warfare Center, Washington Navy Yard, DC./ref> Gives support to the Fleet through the support of Underwater Construction Teams.

After basic UCT training a diver is qualified as a 2nd Class Diver. Training is 26 weeks at the Dive school at Panama City, Florida.
It includes a tactical training phase for advanced combat and demolitions skills.
The training qualifies divers as Underwater Construction Technicians skilled in: seafloor excavation, hydrographic surveys, search and recovery, engineering reconnaissance, and precision demolitions. Senior NCOs are schooled for their supervisory positions whether construction or demolition.
UCT divers can apply for selection to support the Naval Special Warfare Development Group.
Public Works: U.S. Naval Bases
These units have CEC officers leading them and enlisted Seabees for the various crews. About one-third of new Seabees are assigned to Public Works
Public works are a broad category of infrastructure projects, financed and constructed by the government, for recreational, employment, and health and safety uses in the greater community. They include public buildings ( municipal buildings, sc ...
Departments (PWD) at naval installations both within the United States and overseas. While stationed at a Public Works Department, a Seabee can get specialized training and experience in multiple facets of their rating. Many bases have civilians that augment Public Works, but the department is a military operation.
Combat Service Support Detachments (CSSD) / Naval Special Warfare (NSW)
The Seabee detachments have several hundred supporting Naval Special Warfare (NSW) units based out of Coronado, CA, and Virginia Beach, VA. Field support can include camp construction, camp and vehicle maintenance, power generation, transportation logistics, and water purification. The assignment requires additional training in first aid, small arms, driving, specialized equipment, and qualifying as Expeditionary Warfare Specialists. With that qualification a Seabee can be classified as 5306 – Naval Special Warfare (Combat Service Support) or 5307 – Naval Special Warfare (Combat Support). They also can apply for selection to support the Naval Special Warfare Development Group.
Training and Rates
Trainees begin "A" School (trade school) upon completion of Recruit Training Command, Great Lakes, Illinois, boot: 4 weeks classroom, 8 weeks hands-on. From "A" School, trainees most often report to a NMCB or ACB. There recruits go through four-weeks of Expeditionary Combat Skills (ECS) which is also required for those who report to a Navy Expeditionary Combat Command. ECS is basic training in: map reading, combat first aid, recon, and other combat-related skills. Half of each course is spent on basic marksmanship to qualify with an M16 rifle#M16A3, M16 rifle and the Beretta M9, M9 service pistol. Those posted to Alfa Company of a NMCB may be assigned to a crew-served weapon: Mk 19 grenade launcher, MK 19 40mm grenade launcher, the M2 Browning, .50-caliber machine gun, or the M240 machine gun. Many reserve units still field the M60 machine gun. Seabees were last U.S. military to wear the U.S. Woodland camouflage uniform or the Desert Camouflage Uniform. They now have the Navy Working Uniform NWU Type III and use All-purpose Lightweight Individual Carrying Equipment, ALICE field gear. Some units, with the Marines, will use USMC-issue Improved Load Bearing Equipment (ILBE).
Current rates: The current ratings were adopted by the Navy in 1948.
* BU : Builder (United States Navy), Builder
* CE : Construction electrician (United States Navy), Construction Electrician
* CM : Construction mechanic (United States Navy), Construction Mechanic
* EA : Engineering aide

At Uniformed services pay grades of the United States#Enlisted pay grades, paygrade E-8, the Builder, Steelworker, and Engineering Aid rates combine into a single rate: Senior Chief Constructionman (CUCS). Before NAVADMIN 054/21, at the E-9 paygrade they were referred to as a Master Chief Constructionman (CUCM).
Before NAVADMIN 054/21, the remaining Seabee rates combined only at the E-9 paygrade:
* Master Chief Equipmentman (EQCM) for Equipment Operator and Construction Mechanic.
* Master Chief Utilitiesman (UCCM) for Construction Electrician and Utilitiesman.
Per NAVADMIN 054/21: Constructionman Master Chief (CUCM), Equipmentman Master Chief (EQCM) and Utilities Constructionman Master Chief (UCCM) renamed Seabee Master Chief (CBCM). Those Master Chiefs already in CUCM, EQCM or UCCM ratings were to be automatically converted to CBCM on 15 March 2021, but current source ratings badges were to be retained.
Navy diver (United States Navy), Diver is a qualification that the various rates can obtain with three grades: Basic Underwater Construction Technician/ NEC 5932 (2nd Class Diver), Advanced Underwater Construction Technician/ NEC 5931 (1st Class Diver), and Master Underwater Construction Technician/ NEC 5933 (Master diver). Seabee divers are attached to five principal commands outside the NCF:

These are CEC officer billets only. Those at Port Hueneme are with the highly technical NFESC "Dive Locker Team". * United States Navy systems commands, Navy System Commands, e.g., NAVSEA or NAVAIR. These are CEC officer billets only. * NEDU/NDSTC (Navy Experimental Diving Unit Navy Diving & Salvage Training Center)
The "Seabee" and Unit insignias
On 1 March 1942 the RADM Moreell recommended that an insignia be created to promote ''esprit de corps'' in the new CBs to ID their equipment as the Air corps did to ID squadrons. It was not intended for uniforms. Frank J. Iafrate, a civilian file clerk at Quonset Point Advance Naval Base, Davisville, Rhode Island, who created the original "Disney Style" Seabee. In early 1942 his design was sent to RADM Moreell who made a single request. That the Seabee being set inside a letter Q, for Quonset Point, be changed to a hawser rope and it would be officially adopted. The Seabees had a second Logo. It was of a shirtless constructionman holding a sledge hammer with a rifle strapped across his back standing upon the words "Construimus Batuimus USN". The figure was on a shield with a blue field across the top and vertical red and white stripes. A small CEC logo is left of the figure and a small anchor is to the right. This logo was incorporated into many CB Unit insignias. During World War II, artists working for The Walt Disney Company, Disney Insignia Department designed logos for about ten Seabee units including the: 60th NCB, 78th NCB 112th NCB, and the 133rd NCB. There are two Disney published Seabee logos that are not identified with any unit. The end of World War II brought the decommissioning of nearly all of the CBs. They had been in existence less than four years when this happened and the Navy had not created a Historical Branch or Archive for the NCF. So, there was no central archive for Seabee history. As time passed, first with Korea and then Vietnam, Construction Battalions were reactivated with the units having no idea what the World War II insignia had been so they made new ones.Qualification badges and Unit awards
The military qualification badge for the Seabees is known as the Seabee combat warfare specialist insignia (SCW). It was created in 1993 for both officers and enlisted personnel attached to qualifying units: NMCBs, ACBs, UCTs, or NCRs. Its designer, Commander Ross S. Selvidge, CEC, USNR, was the first to wear the insignia.
The Fleet Marine Force Insignia or Fleet Marine Force pin (FMF pin), is for USN officers or enlisted trained and qualified to support the USMC. It comes in three classes : enlisted, officer, and chaplain. For requirements, see: Fleet Marine Force Warfare Specialist (EFMFWS) Program per OPNAV Instruction 1414.4B.
The Peltier Award is given annually to the "Best of Type" active duty Construction Battalion. It was instituted by Rear Admiral Eugene J. Peltier CEC in 1960. He was Commander of BuDocks 1959–1962.
Seabee barge carriers
There were six Seabee (barge), "Seabee" ships built: the SS ''Cape Mendocino'' (T-AKR-5064), the , and three operated by Lykes Brothers Steamship Company. (the SS Doctor Lykes, the SS Tillie Lykes, and the SS Almeria Lykes). The NCF is the principal user of Seabee barges. Barges are shuttled to and from the mother ship, facilitating the unloading of containerized cargo wherever needed. These ships have an elevator system for lifting the barges out of the water at the stern onto the vessel. Barges, loaded or not are elevated to one of the three decks and then moved forward towards the bow on a track to be stored. The ship can carry 38 barges, 12 each on the lower decks and 14 on the upper. The 38 barges have a total capacity for 160 shipping containers. They have a Draft (hull), draft of 2.5', and measure 97'x35'. Besides the barges, the ship has a fuel storage capacity of nearly 36000 m³(9,510,194 gal.) built in its sides and double hull, allowing it to double as a fuel transport. The ships were purchased by the Military Sealift Command.Museums
The U.S. Navy Seabee Museum is located outside the main gate of Naval Base Ventura County, Port Hueneme, Ca. In July 2011 the new facility opened with galleries, grand hall, theater, storage, and research areas.
The Seabee Heritage Center is the Atlantic Coast Annex of the Seabee Museum in Port Hueneme. It opened in 1995. Exhibits at the Gulfport Annex are provided by the Seabee Museum in Port Hueneme.
The Seabee Museum and Memorial Park in Davisville, Rhode Island was opened in the late 1990s. A Fighting Seabee Statue is located there.

B Co from the 25th CB and C Co from the 18th CB were used to form the 53rd CB. The other company was used to form the 121st CB.
*Due to Seabees being given advanced rank upon enlistment, enlisted Marines referred to construction battalions as "sergeant's battalions". USMC sergeants do not pull guard duty, so the ranked Seabees would not be assigned. The NCOs of the 18th wore USMC chevrons and not USN "crows" on their uniforms.

At the construction site of the new embassy twenty to thirty Seabees were assigned to oversee 800 plus Russian construction workers. This prompted the Russians to embed bugs in construction materials prior to delivery to the construction site. The success of the KGB in bugging the new embassy only reinforced the State Department's need for the Seabees.
