The ABM-1 Galosh (Soviet designation A-350 GRAU 5V61) was a Soviet, nuclear armed surface-to-air anti-ballistic missile. The Galosh (NATO reporting name, formerly SH-01) was a component of the A-35 anti-ballistic missile system. Its primary mission was to destroy U.S. Minuteman and Titan intercontinental ballistic missiles targeting Moscow. The ABM-1 was introduced during the 1960s with mechanically steered semi-active radar guidance. It contained a high-yield nuclear warhead, comparable to the U.S. Nike Zeus.
