Helicopter Combat Support Squadron Seven
Helicopter Combat Support Squadron Seven (HC-7) was a helicopter squadron of the United States Navy established on 1 September 1967 and disestablished on 30 June 1975. History Helicopter Combat Support Squadron ONE, (HC-1) was reorganized to create several additional helicopter squadrons. The existing HC-1 Detachments based at NAS Atsugi and NAAF Ream Field, Naval Outlying Landing Field Imperial Beach were redesignated Helicopter Combat Support Squadron SEVEN (HC-7). Established with sixteen officers and seventy-five enlisted men on 1 September 1967. Upon establishment, HC-7 was tasked with multiple missions including Logistics, Vertical Replenishment, Seventh Fleet Flagship, Aerial Mine Countermeasure, Oceanographic, home station search and rescue (SAR) and combat search and rescue (CSAR).

SEATO
The Southeast Asia Treaty Organization (SEATO) was an international organization for collective defense in Southeast Asia created by the Southeast Asia Collective Defense Treaty, or Manila Pact, signed in September 1954 in Manila, the Philippines. The formal institution of SEATO was established on 19 February 1955 at a meeting of treaty partners in Bangkok, Thailand. The organization's headquarters was also in Bangkok. Eight members joined the organization. Primarily created to block further communist gains in Southeast Asia, SEATO is generally considered a failure because internal conflict and dispute hindered general use of the SEATO military; however, SEATO-funded cultural and educational programs left longstanding effects in Southeast Asia. SEATO was dissolved on 30 June 1977 after many members lost interest and withdrew. Origins and structure The Southeast Asia Collective Defense Treaty, or Manila Pact, was signed on 8 September 1954 in Manila, as part of the American T ...

HS-6
Helicopter Sea Combat Squadron SIX (HSC-6), is a helicopter squadron of the United States Navy. It was established as Helicopter Antisubmarine Squadron SIX (HS-6) on 1 June 1956. Its nickname is ''Screamin’ Indians''. On 8 July 2011 it was redesignated Helicopter Sea Combat Squadron SIX (HSC-6). It is based at Naval Air Station North Island, is part of Carrier Air Wing 17 and deploys aboard the aircraft carrier . History Helicopter Anti-Submarine Squadron SIX (HS-6) was established on 1 June 1956 aboard midway between the islands of Formosa and Okinawa. Initially, the squadron flew the Sikorsky HO4S-3, but two years later transitioned to the Sikorsky HSS-1N Seabat greatly enhancing the ability of the squadron to conduct anti-submarine warfare (ASW). In April 1960, the squadron joined Carrier Anti-Submarine Group 53 aboard . In March 1962 the squadron again changed aircraft when the Sikorsky HSS-2 Sea King entered the fleet. In September of that year the HSS-2 was redesi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
1969 EC-121 Shootdown Incident
On 15 April 1969,DPRK supreme leader Kim Il-sung's 57th birthday a United States Navy Lockheed EC-121M Warning Star of Fleet Air Reconnaissance Squadron One (VQ-1) on a reconnaissance mission was shot down by a North Korean MiG-21 aircraft over the Sea of Japan. The plane crashed off the North Korean coast and all 31 Americans (30 sailors and 1 Marine) on board were killed, which constitutes the largest single loss of U.S. aircrew during the Cold War era. The plane was an adaptation of a Lockheed Super Constellation and was fitted with a fuselage radar, so the primary tasks were to act as a long range patrol, conduct electronic surveillance, and act as a warning device. The Nixon administration did not retaliate against North Korea apart from staging a naval demonstration in the Sea of Japan a few days later, which was quickly removed. It resumed the reconnaissance flights within a week to demonstrate that it would not be intimidated by the action while at the same time a ...

Destroyer
In naval terminology, a destroyer is a fast, manoeuvrable, long-endurance warship intended to escort larger vessels in a fleet, convoy or battle group and defend them against powerful short range attackers. They were originally developed in 1885 by Fernando Villaamil for the Spanish NavySmith, Charles Edgar: ''A short history of naval and marine engineering.'' Babcock & Wilcox, ltd. at the University Press, 1937, page 263 as a defense against torpedo boats, and by the time of the Russo-Japanese War in 1904, these "torpedo boat destroyers" (TBDs) were "large, swift, and powerfully armed torpedo boats designed to destroy other torpedo boats". Although the term "destroyer" had been used interchangeably with "TBD" and "torpedo boat destroyer" by navies since 1892, the term "torpedo boat destroyer" had been generally shortened to simply "destroyer" by nearly all navies by the First World War. Before World War II, destroyers were light vessels with little endurance for unattended o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of United States Navy Destroyer Leaders
In the 1930s, the United States Navy built two classes of flotilla leaders, the ''Porter'' class, and the ''Somers'' class. Due to the regulations of the London Naval Treaty, these 13 ships had a displacement of 1,850 tons, compared to the 1,500 tons of a "standard" destroyer. When the treaty ended with the outbreak of World War II in Europe in 1939, the much larger ''Fletcher'' class was constructed, making the differentiation irrelevant. Following the war, destroyer leader (DL) was a hull classification symbol used by the U.S. Navy from the 1950s until 1975. These ships were more commonly called frigates, although they were much larger than frigates of other navies. They were intended to be larger and more capable than destroyers and to lead a destroyer task force. During the 1975 USN ship reclassification these ships were reclassified as guided missile destroyers (DDG) or guided missile cruisers (CG). The last one of these ships was decommissioned in 1999. A total of 41 ship ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
South Vietnam
South Vietnam, officially the Republic of Vietnam ( vi, Việt Nam Cộng hòa), was a state in Southeast Asia that existed from 1955 to 1975, the period when the southern portion of Vietnam was a member of the Western Bloc during part of the Cold War after the 1954 division of Vietnam. It first received international recognition in 1949 as the State of Vietnam within the French Union, with its capital at Saigon (renamed to Ho Chi Minh City in 1976), before becoming a republic in 1955. South Vietnam was bordered by North Vietnam to the north, Laos to the northwest, Cambodia to the southwest, and Thailand across the Gulf of Thailand to the southwest. Its sovereignty was recognized by the United States and 87 other nations, though it failed to gain admission into the United Nations as a result of a Soviet veto in 1957. It was succeeded by the Republic of South Vietnam in 1975. The end of the Second World War saw anti-Japanese Việt Minh guerrilla forces, led by communist fi ...

HC-3
Hemicholinium-3 (HC3), also known as hemicholine, is a drug which blocks the reuptake of choline by the high-affinity choline transporter (ChT; encoded in humans by the gene ''SLC5A7'') at the presynapse. The reuptake of choline is the rate-limiting step in the synthesis of acetylcholine; hence, hemicholinium-3 decreases the synthesis of acetylcholine. It is therefore classified as an indirect acetylcholine antagonist. Acetylcholine is synthesized from choline and a donated acetyl group from acetyl-CoA, by the action of choline acetyltransferase (ChAT). Thus, decreasing the amount of choline available to a neuron will decrease the amount of acetylcholine produced. Neurons affected by hemicholinium-3 must rely on the transport of choline from the soma (cell body), rather than relying on reuptake of choline from the synaptic cleft. Toxicity Hemicholinium-3 is highly toxic because it interferes with cholinergic neurotransmission. The LD50 of hemicholinium-3 for mice is about 35 ...

Boeing Vertol CH-46 Sea Knight
The Boeing Vertol CH-46 Sea Knight is a medium-lift tandem-rotor transport helicopter powered by twin turboshaft engines. It was designed by Vertol and manufactured by Boeing Vertol following Vertol's acquisition by Boeing. Development of the Sea Knight, which was originally designated by the firm as the Vertol Model 107, commenced during 1956. It was envisioned as a successor to the first generation of rotorcraft, such as the H-21 "Flying Banana", that had been powered by piston engines; in its place, the V-107 made use of the emergent turboshaft engine. On 22 April 1958, the V-107 prototype performed its maiden flight. During June 1958, the US Army awarded a contract for the construction of ten production-standard aircraft, designated as the YHC-1A, based on the V-107; this initial order was later cut down to three YHC-1As though. During 1961, the US Marine Corps (USMC), which had been studying its requirements for a medium-lift, twin-turbine cargo/troop assault helicopter, ...
