The B-47 was the world's first swept-wing bomber. It flew its maiden flight in 1947. The B-47 served primarily as a bomber for the Strategic Air Command, with the ability to carry conventional or nuclear weapons. Some B-47s were modified for weather and reconnaissance duties. The B-47 never dropped a bomb in combat and was retired from service in the mid-1960s.

This XB-47, S/N 46-066, is the only surviving prototype of the Stratojet left in the world. Only two were manufactured by Boeing in 1947.

This aircraft is on loan to Octave Chanute Aerospace Museum from the National Museum of the United States Airforce.
