The Boeing B-50 Superfortress is a retired American strategic bomber. A post–World War II revision of the Boeing B-29 Superfortress, it was fitted with more powerful Pratt & Whitney R-4360 radial engines, stronger structure, a taller tail fin, and other improvements. It was the last piston-engined bomber built by Boeing for the United States Air Force, and was refined into Boeing's final such design, the prototype B-54. Although not as well known as its direct predecessor, the B-50 was in USAF service for nearly 20 years.
