AGM-131 SRAM II subclass of nuclear missile
The AGM-131 SRAM II ("Short-Range Attack Missile") was a nuclear air-to-surface missile intended as a replacement for the AGM-69 SRAM. The solid-fueled missile was to be dropped from a B-1B Lancer, carry the W89 warhead and have a range of 400 km. However, the program was canceled by President George H. W. Bush for geopolitical reasons just as the first flight-test missile was delivered.Specifications
