Boeing B-47 Stratojet jet bomber

The Boeing B-47 Stratojet jet bomber was a medium range and size bomber capable of flying at high subsonic speeds and primarily designed for penetrating 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 it never saw major combat use, it was the mainstay of U.S. Air Force Strategic Air Command strategic striking power in the 1950s.
