This is a model of unknown scale of the HAST (high-altitude supersonic target), developed by Beech Aircraft for the U.S. military during the 1970s as a target for missiles fired from U.S. ranges. It flew at a maximum speed of Mach 4 and at an altitude in excess of 100,000 feet. The missile was guided by pre-launch programming and ground control. This artifact was donated by John and Cynthia Heyde to NASM on an unknown date.
This object is on display in James S. McDonnell Space Hangar at the Steven F. Udvar-Hazy Center in Chantilly, VA.
