The North American Aviation Corporation AGM-28 Hound Dog was a supersonic, jet powered, air-launched cruise missile. The Hound Dog was initially given the designation B-77, later re-designated GAM-77, and finally being designated AGM-28. Hound Dog was originally envisioned as a temporary stand off weapon for the B-52, to be used until the AGM-48 Skybolt air launched ballistic missile could be deployed. Instead the Skybolt was canceled and the Hound Dog was deployed for 15 years until the missile was replaced by newer weapons.
Hound Dog development was initiated on March, 15, 1956. The Hound Dog cruise missile engine, airframe and warhead were adaptations of technology developed in the SM-64 Navaho cruise missile. In July 1960, the Hound Dog reached initial operational capability with the first B-52 unit.
One Hound Dog was located under each wing of the B-52, between the fuselage and the inboard engines. The mission of the Hound Dog was to attack segments of the air-defense system in the Soviet Union so that the launching B-52 could penetrate to its primary target. The Hound Dog had a circular error probability of 2.2 miles (3.7 km), acceptable for a weapon equipped with a nuclear warhead. The thermonuclear warhead carried by the Hound Dog was the W28 Class D. The W28 warhead could be configured to yield an explosion between 70 Kilotons and 1.45 Megatons.
