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.
