The Boeing AGM-69 SRAM (Short-Range Attack Missile) was a nuclear air-to-surface missile. It had a range of up to 110 nautical miles (200 km; 130 mi), and was intended to allow US Air Force strategic bombers to penetrate Soviet airspace by neutralizing surface-to-air missile defenses.
The SRAM was designed to replace the older AGM-28 Hound Dog standoff missile which was tasked with the same basic role. The Hound Dog was a very large missile that could only be carried in pairs by the B-52, so some aircraft were tasked with suppressing Soviet missile and radar sites while others would carry on to strike their strategic targets. The SRAM was so much smaller that a number could be carried along with other weapons, allowing a single aircraft to blast a nuclear path through to its targets.
The SRAM entered service in 1972 and was carried by a number of aircraft, including the B-52, FB-111A, and the B-1B. In September 1980 a ground fire raised concerns about the safety of the warhead, and in 1990 they were temporarily removed from service while safety checks were carried out. These revealed a number of the missiles' rocket motors had developed cracks that could have resulted in them exploding when launched.
The SRAM was removed from service in 1993. The weapon was to be replaced by the AGM-131 SRAM II and the new W89 warhead, but the program was terminated at the end of the Cold War.
