The Martin X-23A PRIME (Precision Reentry Including Maneuvering reEntry) was a small lifting body re-entry vehicle tested by the United States Air Force in the mid-1960s. Unlike ASSET primarily used for structural and heating research the X-23 PRIME was developed to study the effects of maneuvering during re-entry of Earth’s atmosphere including cross-range maneuvers up to 710 statute miles (1143 km) off of the ballistic track.
