Full form of ABM
1. Anti Ballistic Missile
Anti ballistic missile (ABM), Weapon designed to intercept and destroy ballistic missiles. Effective ABM systems have been sought since the Cold War, when the nuclear arms race raised the specter of complete destruction by unstoppable ballistic missiles. In the late 1960s both the U.S. and the Soviet Union developed nuclear-armed ABM systems that combined a high-altitude interceptor missile (the U.S. Spartan and Soviet Galosh) with a terminal-phase interceptor (the U.S. Sprint and Soviet Gazelle).
