This is a model of unknown scale of the Soviet's first antiballistic missile (ABM), the three-stage liquid-fuel Galosh. With a range of approximately 350 kilometers and a nuclear warhead, it was designed to destroy incoming U.S. intercontinental and submarine-launched ballistic missiles. The Galosh was first deployed in 1968 at several fixed sites around Moscow, and it is still in service at these locations. John and Cynthia Heyde donated this model to NASM in the late 1980s.
This object is on display in James S. McDonnell Space Hangar at the Steven F. Udvar-Hazy Center in Chantilly, VA.
