Big Blue Blanket
The big blue blanket was an air defense system devised by John Thach during World War II for protecting American warships from attack by Japanese kamikazes. History and tactics As the American island hopping campaign got closer to Japan, the Japanese military began to employ suicide operations more extensively. As Allied losses mounted, a system for countering incoming suicide aircraft was developed. Thach, serving on Admiral Halsey's and Admiral McCain's staff as air operations officer, developed a plan that called for the constant presence of the blue-painted Hellcats and Corsairs over the fleet at all hours. He recommended larger combat air patrols (CAP) stationed farther away from the carriers, a line of picket destroyers and destroyer escorts placed 50 or more miles from the main body of the fleet to provide earlier radar intercepts, and improved coordination between the fighter director officers on board the carriers. Thach also called for dawn-to-dusk fighter sweeps o ...

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 ...

Battle Of Mindoro
The Battle of Mindoro (Filipino: ''Labanan sa Mindoro'') was a battle in World War II between forces of the United States and Japan, in Mindoro Island in the central Philippines, from 13–16 December 1944, during the Philippines Campaign. Troops of the United States Army, supported by the United States Navy and U.S. Army Air Forces (USAAF), made an amphibious landing on Mindoro and defeated Imperial Japanese Army (IJA) forces there. There was no significant opposition from the Imperial Japanese Navy, nor from the Japanese Army and Navy Air Forces, except for ''kamikaze'' (suicide) attacks on American ships. The Japanese force in Mindoro was not large, and was eliminated in three days. The Army was assisted in the campaign by guerrillas from the local Filipino population. The U.S. captured Mindoro to establish airfields there, which would be in fighter range of Lingayen Gulf in northern Luzon Island, where the next major amphibious invasion of the Philippines was planned. ...

Troopship
A troopship (also troop ship or troop transport or trooper) is a ship used to carry soldiers, either in peacetime or wartime. Troopships were often drafted from commercial shipping fleets, and were unable land troops directly on shore, typically loading and unloading at a seaport or onto smaller vessels, either tenders or barges. Attack transports, a variant of ocean-going troopship adapted to transporting invasion forces ashore, carry their own fleet of landing craft. Landing ships beach themselves and bring their troops directly ashore. History Ships to transport troops were used in Antiquity. Ancient Rome used the navis lusoria, a small vessel powered by rowers and sail, to move soldiers on the Rhine and Danube. The modern troopship has as long a history as passenger ships do, as most maritime nations enlisted their support in military operations (either by leasing the vessels or by impressing them into service) when their normal naval forces were deemed insufficient fo ...

Aircraft Carrier
An aircraft carrier is a warship that serves as a seagoing airbase, equipped with a full-length flight deck and facilities for carrying, arming, deploying, and recovering aircraft. Typically, it is the capital ship of a fleet, as it allows a naval force to project air power worldwide without depending on local bases for staging aircraft operations. Carriers have evolved since their inception in the early twentieth century from wooden vessels used to deploy balloons to nuclear-powered warships that carry numerous fighters, strike aircraft, helicopters, and other types of aircraft. While heavier aircraft such as fixed-wing gunships and bombers have been launched from aircraft carriers, these aircraft have not successfully landed on a carrier. By its diplomatic and tactical power, its mobility, its autonomy and the variety of its means, the aircraft carrier is often the centerpiece of modern combat fleets. Tactically or even strategically, it replaced the battleship in the ro ...

Delayed Action Fuse
A delay-action bomb is an aerial bomb designed to explode some time after impact, with the bomb's fuzes set to delay the explosion for times ranging from very brief to several weeks. Short delays are used to allow the bomb to penetrate before exploding: "a delay action bomb striking the roof of a tall building will penetrate through several floors before bursting". A short delay would also prevent a fighter-bomber or ground-attack aircraft getting caught in the blast of its own bomb after a low-altitude attack. Longer delays were intended to disrupt salvage and other activities, to spread terror in areas where there could still be live bombs and to attack bomb disposal workers. Such bombs were used widely by British, American, and German forces during World War II. One use was to hamper and delay reconstruction and repair of bombed airfields. Towards the end of the war both British and German bombs became ''de facto'' mines, with a secondary fuze mechanism activated by light tilti ...

Radar
Radar is a detection system that uses radio waves to determine the distance (''ranging''), angle, and radial velocity of objects relative to the site. It can be used to detect aircraft, ships, spacecraft, guided missiles, motor vehicles, weather formations, and terrain. A radar system consists of a transmitter producing electromagnetic waves in the radio or microwaves domain, a transmitting antenna, a receiving antenna (often the same antenna is used for transmitting and receiving) and a receiver and processor to determine properties of the objects. Radio waves (pulsed or continuous) from the transmitter reflect off the objects and return to the receiver, giving information about the objects' locations and speeds. Radar was developed secretly for military use by several countries in the period before and during World War II. A key development was the cavity magnetron in the United Kingdom, which allowed the creation of relatively small systems with sub-meter resolution. Th ...

Destroyer Escort
Destroyer escort (DE) was the United States Navy mid-20th-century classification for a warship designed with the endurance necessary to escort mid-ocean convoys of merchant marine ships. Development of the destroyer escort was promoted by the British need in World War II for anti-submarine ships that could operate in open oceans at speeds of up to 20 knots. These "British Destroyer Escort"s were designed by the US for mass-production under Lend Lease as a less expensive alternative to fleet destroyers. The Royal Navy and Commonwealth forces identified such warships as frigates, and that classification was widely accepted when the United States redesignated destroyer escorts as frigates (FF) in 1975. From circa 1954 until 1975 new-build US Navy ships designated as destroyer escorts (DE) were called ocean escorts. Similar types of warships in other navies of the time included the 46 diesel-engined ''Kaibōkan'' of the Imperial Japanese Navy, 10 ''Kriegsmarine'' F-class escort ...

Combat Air Patrol
Combat air patrol (CAP) is a type of flying mission for fighter aircraft. A combat air patrol is an aircraft patrol provided over an objective area, over the force protected, over the critical area of a combat zone, or over an air defense area, for the purpose of intercepting and destroying hostile aircraft before they reach their target. Combat air patrols apply to both overland and overwater operations, protecting other aircraft, fixed and mobile sites on land, or ships at sea. Known by the acronym CAP, it typically entails fighters flying a tactical pattern around or screening a defended target, while looking for incoming attackers. Effective CAP patterns may include aircraft positioned at both high and low altitudes, in order to shorten response times when an attack is detected. Modern CAPs are either GCI or AWACS-controlled to provide maximum early warning for defensive reaction. The first CAPs were characteristic of aircraft carrier operations, where CAPs were flown to ...

Air Defense
Anti-aircraft warfare, counter-air or air defence forces is the battlespace response to aerial warfare, defined by NATO as "all measures designed to nullify or reduce the effectiveness of hostile air action".AAP-6 It includes surface based, subsurface ( submarine launched), and air-based weapon systems, associated sensor systems, command and control arrangements, and passive measures (e.g. barrage balloons). It may be used to protect naval, ground, and air forces in any location. However, for most countries, the main effort has tended to be homeland defence. NATO refers to airborne air defence as counter-air and naval air defence as anti-aircraft warfare. Missile defence is an extension of air defence, as are initiatives to adapt air defence to the task of intercepting any projectile in flight. In some countries, such as Britain and Germany during the Second World War, the Soviet Union, and modern NATO and the United States, ground-based air defence and air defence aircraf ...

Vought F4U Corsair
The Vought F4U Corsair is an American fighter aircraft which saw service primarily in World War II and the Korean War. Designed and initially manufactured by Chance Vought, the Corsair was soon in great demand; additional production contracts were given to Goodyear, whose Corsairs were designated FG, and Brewster, designated F3A. The Corsair was designed and operated as a carrier-based aircraft, and entered service in large numbers with the U.S. Navy in late 1944 and early 1945. It quickly became one of the most capable carrier-based fighter-bombers of World War II. Some Japanese pilots regarded it as the most formidable American fighter of World War II and its naval aviators achieved an 11:1 kill ratio. Early problems with carrier landings and logistics led to it being eclipsed as the dominant carrier-based fighter by the Grumman F6F Hellcat, powered by the same Double Wasp engine first flown on the Corsair's initial prototype in 1940. Instead, the Corsair's early deployme ...
