The two-place T-33 jet was designed for advanced pilot training and was developed from the single-seat F-80 fighter by lengthening the fuselage to accommodate a second cockpit. The T-33 made its first flight in 1948, and production continued until 1959, with 5,691 built. In addition to its use as a trainer, it served as a drone director, towed targets, and in some cases retained two machine guns for gunnery training and employment as a combat aircraft. It also served as an airborne target to dispense chaff and emit electronic countermeasures. One of the world's best-known aircraft, it served with the air forces of more than twenty nations over several decades. Power came from a single Allison J33-A-35 turbojet engine delivering 5,400 pounds of thrust. This "Shooting Star" joined the 5th Fighter Interceptor Squadron in July 1961 and was retired in 1988.
