The Boeing B-52 Stratofortress has eight engines.
The B-52 was designed as a long-range strategic bomber and originally used eight turbojet engines mounted in four twin-engine pods beneath its wings. Later B-52H aircraft use eight Pratt & Whitney TF33 turbofan engines.
The aircraft’s eight-engine arrangement reflects the propulsion technology and mission requirements of the early jet era. Its large fuel capacity, swept wings, and long range allowed it to conduct intercontinental missions. The B-52 first flew in 1952 and entered U.S. Air Force service in 1955.
The B-52 is sometimes confused with later bombers that have fewer engines, such as the four-engine B-1B Lancer. The planned modernization of B-52H aircraft with eight Rolls-Royce F130 engines changes the engine type, not the number of engines.
