The Lockheed T2V SeaStar, later called the T-1 SeaStar, is a carrier-capable jet trainer for the United States Navy that entered service in May 1957. Developed from the Lockheed T-33 (itself derived from the Lockheed P-80 Shooting Star), it was powered by one Allison J33 engine.

Design and development

Starting in 1949, the U.S. Navy used the Lockheed T-33 for land-based jet aircraft training. The T-33 was a derivative of the Lockheed P-80/F-80 fighter and was first named TO-2, then TV-2 in Navy service. However, the TV-2 was not suitable for operation from aircraft carriers. The persisting need for a carrier-compatible trainer led to a further, more advanced design development of the P-80/T-33 family, which came into being with the Lockheed designation L-245 and USN designation T2V. Lockheed's demonstrator L-245 first flew on 16 December 1953 and production deliveries to the US Navy began in 1956. [1]

Compared to the T-33/TV-2, the T2V was almost totally re-engineered for carrier landings and at-sea operations with a redesigned tail, naval standard avionics, a strengthened undercarriage (with catapult fittings) and lower fuselage (with a retractable arrestor hook), power-operated leading-edge flaps (to increase lift at low speeds) to allow carrier launches and recoveries, and an elevated rear (instructor's) seat for improved instructor vision, among other changes. Unlike other P-80 derivatives, the T2V could withstand the shock of landing on a pitching carrier deck and had a much higher ability to withstand sea water-related aircraft wear from higher humidity and salt exposure.

Operational history

The only version of the T2V was initially designated T2V-1 when it entered service, but was redesignated T-1A SeaStar under the 1962 United States Tri-Service aircraft designation system, the designation under which it would spend the majority of its career.

The T-1A was replaced by the North American T-2 Buckeye but remained in service into the 1970s.

<span class="mw-page-title-main">McDonnell FH Phantom</span> Early US twinjet fighter aircraft

The McDonnell FH Phantom is a twinjet fighter aircraft designed and first flown during World War II for the United States Navy. The Phantom was the first purely jet-powered aircraft to land on an American aircraft carrier and the first jet deployed by the United States Marine Corps. Although only 62 FH-1s were built it helped prove the viability of carrier-based jet fighters. As McDonnell's first successful fighter, it led to the development of the follow-on F2H Banshee, which was one of the two most important naval jet fighters of the Korean War; combined, the two established McDonnell as an important supplier of navy aircraft.

The Lockheed P-80 Shooting Star was the first jet fighter used operationally by the United States Army Air Forces (USAAF) during World War II. Designed and built by Lockheed in 1943 and delivered just 143 days from the start of design, production models were flying, and two pre-production models did see very limited service in Italy just before the end of World War II. Designed with straight wings, the type saw extensive combat in Korea with the United States Air Force (USAF) as the F-80.

The McDonnell F2H Banshee is a single-seat carrier-based jet fighter aircraft designed and produced by the American aircraft manufacturer McDonnell Aircraft. It was an early jet fighter operated by United States Navy and United States Marine Corps, as well as being the only jet-powered fighter to ever be deployed by the Royal Canadian Navy. The aircraft's name is derived from the banshee of Irish mythology.

The Lockheed T-33 Shooting Star is an American subsonic jet trainer. It was produced by Lockheed and made its first flight in 1948. The T-33 was developed from the Lockheed P-80/F-80 starting as TP-80C/TF-80C in development, then designated T-33A. It was used by the U.S. Navy initially as TO-2, then TV-2, and after 1962, T-33B. The last operator of the T-33, the Bolivian Air Force, retired the type in July 2017, after 44 years of service.

<span class="mw-page-title-main">North American AJ Savage</span> Carrier-based bomber aircraft

The North American AJ Savage is an American carrier-based medium bomber built for the United States Navy by North American Aviation. The aircraft was designed shortly after World War II to carry atomic bombs and this meant that the bomber was the heaviest aircraft thus far designed to operate from an aircraft carrier. It was powered by two piston engines and a turbojet buried in the rear fuselage. The AJ-1 first became operational in 1950 and several were based in South Korea during 1953 as a deterrent against North Korea. Of the 140 built, plus three prototypes, 30 were reconnaissance aircraft. Inflight-refueling equipment was deployed on the Savage in the mid-1950s. The bomber was replaced by the Douglas A3D Skywarrior beginning in 1957.

The Lockheed Model 10 Electra is an American twin-engined, all-metal monoplane airliner developed by the Lockheed Aircraft Corporation in the 1930s to compete with the Boeing 247 and Douglas DC-2.

The Lockheed P-2 Neptune is a maritime patrol and anti-submarine warfare (ASW) aircraft. It was developed for the US Navy by Lockheed to replace the Lockheed PV-1 Ventura and PV-2 Harpoon, and was replaced in turn by the Lockheed P-3 Orion. Designed as a land-based aircraft, the Neptune never made a carrier landing, but a small number were converted and deployed as carrier-launched, stop-gap nuclear bombers that would have to land on shore or ditch. The type was successful in export, and saw service with several armed forces.

The Martin P4M Mercator was a maritime reconnaissance aircraft built by the Glenn L. Martin Company. The Mercator was an unsuccessful contender for a United States Navy requirement for a long-range maritime patrol bomber, with the Lockheed P2V Neptune chosen instead. It saw a limited life as a long-range electronic reconnaissance aircraft. Its most unusual feature was that it was powered by a combination of piston engines and turbojets, the latter being in the rear of the engine nacelles.

The Ryan FR Fireball was an American mixed-power fighter aircraft designed by Ryan Aeronautical for the United States Navy during World War II. It was the Navy's first aircraft with a jet engine. Only 66 aircraft were built before Japan surrendered in August 1945. The FR-1 Fireball equipped a single squadron before the war's end, but did not see combat. The aircraft ultimately proved to lack the structural strength required for operations aboard aircraft carriers and was withdrawn in mid-1947.

The Lockheed R6V Constitution was a large, propeller-driven, double-decker transport aircraft developed in the 1940s by Lockheed as a long-range, high-capacity transport and airliner for the U.S. Navy and Pan American Airways. Only two of the aircraft were ever built, both prototypes. Although these two planes went into service with the Navy, the Constitution design ultimately proved underpowered and too large for practical airline use at the time. Although the Martin JRM Mars flying boat had a slightly longer wingspan, the Constitution remains the largest fixed-wing aircraft type ever operated by the U.S. Navy.

The Vought F6U Pirate was the Vought company's first jet fighter, designed for the United States Navy during the mid-1940s. Although pioneering the use of turbojet power as the first naval fighter with an afterburner and composite material construction, the aircraft proved to be underpowered and was judged unsuitable for combat. None were ever issued to operational squadrons and they were relegated to development, training, and test roles before they were withdrawn from service in 1950.
