The X-38 was a technology demonstrator for the proposed Crew Return Vehicle (CRV) for the International Space Station. It was an unpiloted lifting body designed at 80 percent of the size of a CRV. (Two later versions were planned at 100 percent of the CRV size.) It was patterned after a lifting-body shape first employed in the Air Force-NASA X-24 lifting-body project in the early to mid-1970s.

In tests it was dropped by a B-52 from altitudes of up to 45,000 ft (13,700 m), gliding at near transonic speeds before deploying a drogue parachute to slow it to 60 mph (95 km/h). Its descent continued under a 7,500 ft² (700 m²) parafoil wing, the largest ever made.

Flight control was mostly autonomous, backed up by a ground-based pilot.

The X-38 project was cancelled on April 29, 2002 due to budget concerns.
