The AGM-131A SRAM (Short Range Attack Missile) II was a short-range, self-guided nuclear weapon designed during the Cold War, but it was canceled before entering production. It was a follow-on to the original AGM-69 SRAM, which entered service in the 1970s.
The air-launched, rocket-propelled SRAM II had a range of 250 miles and carried a single nuclear warhead in the kiloton range. It also incorporated a digitally-controlled warhead with improved safety features.
Full-scale development began in 1987, but the SRAM II program ended in 1991 as part of an arms control initiative and because of production problems with the missile's motor. This was moved from the fourth building to the Cold War Gallery on March, 18, 2026 and is located under the B-1 aircraft.
