An aircraft carrier is a warship that serves as a seagoing airbase, equipped with a full-length flight deck and hangar facilities for supporting, arming, deploying and recovering shipborne aircraft. Typically it is the capital ship of a fleet, as it allows a naval force to project seaborne air power far from homeland without depending on local airfields for staging aircraft operations. Since their inception in the early 20th century, aircraft carriers have evolved from wooden vessels used to deploy individual tethered reconnaissance balloons, to nuclear-powered supercarriers that carry dozens of fighters, strike aircraft, military helicopters, AEW&Cs and other types of aircraft such as UCAVs. While heavier fixed-wing aircraft such as airlifters, gunships and bombers have been launched from aircraft carriers, these aircraft have not landed on a carrier due to flight deck limitations.
The escort carrier or escort aircraft carrier, also called a "jeep carrier" or "baby flattop" in the United States Navy (USN) or "Woolworth Carrier" by the Royal Navy, was a small and slower type of aircraft carrier used by the Royal Navy, the Royal Canadian Navy, the United States Navy, the Imperial Japanese Navy and Imperial Japanese Army Air Force in World War II. They were typically half the length and a third the displacement of larger fleet carriers, more-lightly armed and armored, and carried fewer planes. Escort carriers were most often built upon a commercial ship hull, so they were cheaper and could be built quickly. This was their principal advantage as they could be completed in greater numbers as a stop-gap when fleet carriers were scarce. However, the lack of protection made escort carriers particularly vulnerable, and several were sunk with great loss of life. The light carrier was a similar concept to the escort carrier in most respects, but was fast enough to operate alongside fleet carriers.
The Invincible class was a class of light aircraft carrier operated by the Royal Navy. Three ships were constructed: HMS Invincible, HMS Illustrious and HMS Ark Royal. The vessels were built as aviation-capable anti-submarine warfare (ASW) platforms to counter the Cold War North Atlantic Soviet submarine threat, and initially embarked Sea Harrier aircraft and Sea King HAS.1 anti-submarine helicopters. With cancellation of the aircraft carriers renewal programme in the 1960s, the three ships became the replacements for Ark Royal and Eagle fleet carriers and the Centaur-class light fleet carriers, and the Royal Navy's sole class of aircraft carrier.
A light aircraft carrier, or light fleet carrier, is an aircraft carrier smaller than the standard carriers of a navy. The precise definition of the type varies by country; light carriers typically have a complement of aircraft only one-half to two-thirds the size of a full-sized fleet carrier. A light carrier was similar in concept to an escort carrier in most respects; however, light carriers were intended for higher speeds to be deployed alongside fleet carriers, while escort carriers were typically relatively slow and usually defended equally slow convoys, as well as providing air support during amphibious operations.
HMS Chaser (D32/R306/A727) was an American-built Attacker-class escort carrier that served with the Royal Navy during the Second World War.
HMS Nabob (D77) was a Ruler-class escort aircraft carrier which served in the Royal Navy during 1943 and 1944. The ship was built in the United States as the Bogue-classUSS Edisto (CVE-41) but did not serve with the United States Navy. In August 1944 the ship was torpedoed by the German submarine U-354 while participating in an attack on the German battleship Tirpitz. Nabob survived the attack, but upon returning to port, was considered too damaged to repair. The escort carrier remained in port for the rest of the war and was returned to the United States following it. Nabob is one of two Royal Navy escort carriers built in the United States which is listed as lost in action during World War II. The ship was sold for scrap by the United States but found a second life when purchased and converted for mercantile use under her British name, Nabob. Later renamed Glory, the ship was sold for scrapping in 1977.
The 1942 Design Light Fleet Carrier, commonly referred to as the British Light Fleet Carrier, was a light aircraft carrier design created by the Royal Navy during the Second World War, and used by eight naval forces between 1944 and 2001. They were designed and constructed by civilian shipyards to serve as an intermediate step between the expensive, full-size fleet aircraft carriers and the less expensive but limited-capability escort carriers.
HMS Venerable (R63) was a Colossus-class aircraft carrier of the Royal Navy. She served for only the last few months of World War II, and in 1948 she was sold to the Netherlands and renamed HNLMS Karel Doorman, taking part in the military clash in 1962 in Western New Guinea. Subsequently, she was sold to Argentina and renamed ARA Veinticinco de Mayo, later taking part in the Falklands War.
HMS Perseus was a Colossus-class light fleet aircraft carrier built for the Royal Navy during World War II. The ship was initially named HMS Edgar, but she was renamed in 1944 when the Admiralty decided to convert her into an aircraft maintenance carrier. She was completed in 1945, after the end of World War II, and she made a trip to Australia late in the year. Upon her return to the UK in early 1946, Perseus was placed in reserve. The ship was recommissioned in 1950 to serve as the trials ship for the steam catapult then under development. Over 1,600 test launches were conducted before the catapult was removed in 1952 and she was converted for use as a ferry carrier to transport aircraft, troops and equipment overseas. She was reduced to reserve again in 1954 and sold for scrap in 1958.
USS St. Simon (CVE-51), an escort aircraft carrier originally classified as an auxiliary aircraft carrier, was laid down on 26 April 1943 at Tacoma, Washington, by the Seattle-Tacoma Shipbuilding Corporation, under a Maritime Commission contract ; reclassified as an escort aircraft carrier, CVE-51, on 15 July 1943; launched on 9 September 1943; sponsored by Mrs. R. H. Lewis, the wife of Major General R. H. Lewis, Commanding General, Northwestern Sector, Fort Lewis, Washington; assigned to the Commercial Iron Works, Portland, Oregon, for the completion of construction; and delivered to the Royal Navy, under lend-lease, on 31 December 1943.
USS Willapa (AVG-53/ACV-53/CVE-53) was a Bogue-class escort carrier built during World War II for the United States Navy. Never seeing American service, the ship was transferred to the United Kingdom as part of Lend-Lease. The escort carrier was renamed HMS Puncher (D79) of the British Ruler class and crewed by the Royal Canadian Navy with aircrew from the Fleet Air Arm. Primarily used as an aircraft transport, Puncher took part in operations along the Norwegian coast towards the end of the war. Following the war the ship was converted for mercantile service and renamed Muncaster Castle, Bardic and Ben Nevis, before being broken up in 1973.
The Tiger class were a class of three British warships of the 20th century and the last all-gun cruisers of the Royal Navy. Construction of three Minotaur-class cruisers began during World War II but, due to post-war austerity, the Korean War and focus on the Royal Air Force over the surface fleet, the hulls remained unfinished. Against a background of changing priorities and financial constraints, approval to complete them to a modified design was given in November 1954 and the three ships – Tiger, Lion and Blake – entered service from March 1959.
HMS Prince of Wales (R09) is the second Queen Elizabeth-class aircraft carrier and the Fleet Flagship of the Royal Navy. Prince of Wales is not fitted with catapults and arrestor wires, and is instead designed to operate STOVL aircraft; the ship is currently planned to carry up to 48 F-35B Lightning II stealth multirole fighters and Merlin helicopters for airborne early warning and anti-submarine warfare, although in surge conditions the class is capable of supporting 70+ F-35B. The design emphasises flexibility, with accommodation for 250 Royal Marines and the ability to support them with attack helicopters and troop transports up to and larger than Chinook size.
Landing platform helicopter (LPH) is a term used by some navies to denote a type of amphibious warfare ship designed primarily to operate as a launch and recovery platform for helicopters and other VTOL aircraft. As such, they are considered a type of helicopter carrier.
HMS Unicorn was an aircraft repair ship and light aircraft carrier built for the Royal Navy in the late 1930s. She was completed during World War II and provided air cover over the amphibious landing at Salerno, Italy, in September 1943. The ship was transferred to the Eastern Fleet in the Indian Ocean at the end of the year. Unicorn supported the aircraft carriers of the fleet on their operations until the British Pacific Fleet (BPF) was formed in November 1944. She was transferred to Australia in early 1945 to support the BPF's operations during Operation Iceberg, the Allied invasion of Okinawa in May. To shorten the time required to replenish the BPF's carriers, the ship was based in the Admiralty Islands and in the Philippine Islands until the Japanese surrender in August. Unicorn was decommissioned and placed in reserve when she returned to the UK in January 1946.
The Royal Navy built three aircraft maintenance carriers for its Fleet Air Arm before and during World War II. The Abyssinia Crisis of 1934–35 demonstrated to the Admiralty that it needed a depot ship to support the aircraft carriers in active service, just like submarine and destroyer tenders supported those types. Begun just before the start of World War II in 1939, HMS Unicorn was the first ship built in any navy that could "carry out the full range of aircraft maintenance and repair work in addition to the ability to operate aircraft from the flight deck". Unicorn proved the value of the concept and two similar support ships, Perseus and Pioneer were converted into aircraft maintenance ships by modifying light carriers while still under construction. Unlike Unicorn, neither Pioneer nor Perseus were able to land aircraft; they had to be craned aboard.
The following is a timeline of fleet aircraft carriers of the Royal Navy of the United Kingdom. The first British aircraft carrier was HMS Argus, a converted liner hull.
1850 Naval Air Squadron was a Fleet Air Arm (FAA) naval air squadron of the United Kingdom’s Royal Navy (RN). It formed in the United States at RN Air Section Brunswick as a fighter squadron in August 1944, with Vought Corsair aircraft before joining HMS Reaper to cross the Atlantic. On arrival in the UK it expanded its aircraft absorbing part of the disbanded 1849 Naval Air Squadron. After working up at HMS Gadwall, at RNAS Belfast, HMS Gannet, at RNAS Eglinton and HMS Wagtail, at RNAS Ayr, the squadron undertook deck landing training on HMS Venerable during February 1945, before joining her sister ship, HMS Vengeance. The ship sailed for the Far East to join the British Pacific Fleet and the squadron went ashore to HMS Valluru at Tambaram and HMS Garuda, at Coimbatore, in southern India in June for weapon training and dive bombing practice, becoming part of the 13th Carrier Air Group. With the end of the Second World War it returned to the UK and disbanded at HMS Siskin, at RNAS Gosport, in August 1946.
