OTV-6 (X-37B)

The Boeing X-37, also known as the Orbital Test Vehicle (OTV), is a reusable uncrewed spacecraft. It is boosted into space by a launch vehicle, then re-enters Earth's atmosphere and lands as a spaceplane. The X-37 is operated by the United States Air Force for orbital spaceflight missions intended to demonstrate reusable space technologies. It is a 120%-scaled derivative of the earlier Boeing X-40.
