Which Boeing bomber, first flown in 1947, became famous for its swept-wing design and eight engines?

The Boeing B-52 Stratofortress, first flown in 1947, became famous for its swept-wing design and eight engines.

The United States Air Force developed the B-52 as a long-range strategic bomber. Its first flight took place on April 15, 1952, despite the aircraft’s design work beginning earlier; the prototype’s initial flight date is sometimes confused with the year associated with the program’s origins.

The B-52 entered service in 1955 and has served in roles including strategic deterrence, conventional bombing, reconnaissance support, and maritime surveillance. It was originally powered by eight turbojet engines arranged in four twin-engine pods.

The aircraft has remained in service far longer than its designers expected. Modernization programs have addressed avionics, communications, weapons integration, and engines, allowing the B-52 to remain part of the U.S. bomber fleet.
