The Lockheed T-33 Shooting Star was an American subsonic jet trainer developed from the P-80/F-80 fighter by lengthening the fuselage to accommodate a second cockpit. First flying in 1948, it became a widely used advanced trainer by the U.S. Air Force and Navy, as well as numerous air forces worldwide, earning the nickname “T-Bird.” Beyond training, it served in roles like drone director, target towing, and even limited combat in some countries. Its long service life extended into the 21st century with some operators, making it one of the most successful jet trainers ever produced.
