![]() ![]() A few served as flying testbeds up until 1977. ![]() The type remained in service as a reconnaissance aircraft until 1969. While never seeing combat as a bomber, reconnaissance RB-47s would occasionally come under fire near or within Soviet air space. The B-47 was also adapted to perform a number of other roles and functions, including photographic reconnaissance, electronic intelligence, and weather reconnaissance. The B-47 was in service as a strategic bomber until 1965, at which point it had largely been supplanted by more capable aircraft, such as Boeing's own B-52 Stratofortress. Over 2,000 were manufactured to meet the Air Force's demands, driven by the tensions of the Cold War. This would be soon followed by much larger contracts.ĭuring 1951, the B-47 entered operational service with the United States Air Force's Strategic Air Command (SAC), becoming a mainstay of its bomber strength by the late 1950s. Facing off competition such as the North American XB-45, Convair XB-46 and Martin XB-48, a formal contract for 10 B-47A bombers was signed on 3 September 1948. Suitably impressed, in April 1946, the USAAF ordered two prototypes, designated "XB-47" on 17 December 1947, the first prototype performed its maiden flight. With its engines carried in nacelles underneath the wing, the B-47 represented a major innovation in post- World War II combat jet design, and contributed to the development of modern jet airliners. ![]() ![]() Another key innovation adopted during the development process was the swept wing, drawing upon captured German research. The primary mission of the B-47 was as a nuclear bomber capable of striking targets within the Soviet Union.ĭevelopment of the B-47 can be traced back to a requirement expressed by the United States Army Air Forces (USAAF) in 1943 for a reconnaissance bomber that harnessed newly developed jet propulsion. The Boeing B-47 Stratojet (Boeing company designation Model 450) is a retired American long- range, six-engined, turbojet-powered strategic bomber designed to fly at high subsonic speed and at high altitude to avoid enemy interceptor aircraft. ![]()
