B-47 Stratojet

The Boeing B-47 Stratojet was a medium-range and medium-size jet bomber capable of flying at high subsonic speeds and primarily designed for penetrating the airspace of the Soviet Union. A major innovation in post-World War II combat jet design, it helped lead to the development of modern jet airliners.

The Boeing B-47 Stratojet was a medium-range and medium-size jet bomber capable of flying at high subsonic speeds and primarily designed for penetrating the airspace of the Soviet Union. A major innovation in post-World War II combat jet design, it helped lead to the development of modern jet airliners. While the B-47 never saw major combat use, it remained a mainstay of the U.S. Air Force's Strategic Air Command (SAC) during the 1950s and early 1960s. The B-47 arose from a 1943 U.S. Army Air Forces requirement for a jet bomber and reconnaissance aircraft that could reach Nazi Germany in the event that Great Britain fell. The next year, the requirement evolved into a formal request for a bomber with a specified speed of 500 mph (800 km/h) or more, a range of 3,500 mi (5,600 km), and a service ceiling of 40,000 ft (12,200 m). It envisioned using the General Electric TG-180 turbojet engine, then in development. The subsequent von Kármán mission inspected Nazi Germany laboratories from... less
