The Boeing B-50 is a strategic bomber developed in the late 1940s as an improvement over the earlier B-29 Superfortress. It features a pressurized cabin, advanced engines, and increased payload capacity, allowing it to carry both conventional and nuclear weapons. The B-50 was primarily used by the United States Air Force during the Cold War. First flown in 1947, the B-50 entered service in 1949 and served until the mid-1960s. It played a crucial role in the U.S. military's long-range bombing capabilities and was also used for aerial refueling missions. The aircraft was eventually phased out as newer models, like the B-52 Stratofortress, became available.
