The Lockheed T-33 Shooting Star (or T-Bird) is a subsonic American 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.
