AGM-69 SRAM

The Boeing AGM-69 SRAM (Short-Range Attack Missile) was an air-to-surface missile with a nuclear warhead. 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...
