The Pratt & Whitney TF33-P-3 engine is the engine variant of the Pratt and Whitney TF33 engine that is installed on the B52-H aircraft. The TF33 is the military version of the Pratt & Whitney JT3D which is a low-bypass-ratio engine built around the Pratt & Whitney J57 turbojet core. The JT3 made its first flight on a Boeing 707-120 aircraft on June 22, 1960.

The TF33 powered the first flight of the Air Force's B-52H Stratofortress on March 6, 1961. The Air Force also used it for transports such as the Lockheed C-141 Starlifter and Boeing C-135B Stratolifter. In 1973, the Air Force selected a TF33 model for its E3A Airborne Warning and Control System (AWACS) airplane manufactured by Boeing.
