The Lockheed T2V SeaStar, later called the T-1 SeaStar, was a turbojet trainer aircraft for the U.S. Navy that entered service in May 1957. It was developed from the Lockheed T-33 and powered by one Allison J33 engine.

Design and development

It was based upon the Lockheed L-245 design of an updated T-33/P-80 reworked into a naval version for carrier operations. The Navy used the T-33 as the TV-2 (intially TO-2) starting in 1949 for land based jet aircraft training, but this model was not usable on aircraft carriers. Based on the more advanced design development of the P-80 family, the T2V had to be almost totally re-engineered for carrier landing 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), and 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. The Navy did also fly a number of T-33s for land-based training operations, designated TV-2, which should not be confused with the T2V (T-1 SeaStar).

Operational history

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

It was replaced by the T-2 Buckeye but remained in service into the 1970s.
