AGM-28 Hound Dog Missile



   The Hound Dog was SAC's first air-launched missile.  One was carried under each wing of the B-52G Stratofortress.  Their mission was to attack and destroy enemy air defenses, such as fighter aircraft bases, communication centers, and anti-aircraft missile batteries thus clearing the way for the bomber to more successfully strike its target.  It was named after the popular Elvis Presley song, "You Ain't Nothing But a Hound Dog."
    Each Missile had a J52 jet engine.  In addition to its own fuel tank, the missiles were integrated with the Stratofortress fuel system.  This permitted their use as auxiliary engines.  For example, a heavily loaded B-52 could use them on takeoff in addition to its own eight jet engines.
    The Hound Dog was originally designated B-77, but this was quickly changed to GAM-77 and later changed again to AGM-28.  The AGM-28 missile program began on March 15, 1956 when Headquarters Air Force issued a General Operations Requirement (GOR 148) for an air-to-surface missile to be carried on the B-52 strategic manned bomber. On 16 October 1958, Headquarters USAF awarded a Hound Dog production contract to North American Aviation, Inc.
      In February 1958, growing concern about both the perceived unfavorable shift in the strategic balance and the increasing vulnerability of penetrating bombers prompted USAF to accelerate the Hound Dog. On 21 December 1959, General Thomas S. Power, Commander in Chief of the Strategic Air Command, formally accepted the first production model Hound Dog missiles in a ceremony conducted at North American Aviation's Downey, California plant. Headquarters Air Force finalized the Hound Dog missile program at the end of fiscal year 1959 when it approved a force of 29 B-52 squadrons equipped with Hound Dog missiles. The first launch of the missile from a B-52, first designated GAM-77, then AGM-28, took place in April 1959.
    The Hound Dog utilized a delta wing configuration, and a self-contained inertial auto-navigation guidance system. It has a range of 350 miles and a speed of Mach 2 at over 55,000 feet. It carried a 1,742-pound warhead (four megatons) approximately 500 nautical miles from its launch point at high altitude and supersonic speed, or approximately 200 nautical miles from its launch point at low altitude and subsonic (1,000 feet at Mach .83) profile.  Accuracy was adaquate considering the four megaton warhead, but two other problems hindered the missile. Reliability was a constant concern and in addition the two five-ton missiles, carried on pylons, degraded B-52 flight performance.
    North American delivered the first production Hound Dog in December 1959. SAC launched its first AGM-28 in February 1960; by the following July, one wing was operational with the weapon, although the first airborne alert with it did not take place until January 1962.
     The numbers of Hound Dogs in the B-52 fleet rapidly grew from 54 in 1960, rising to 230 the next year, 547 in 1962, and 593 in 1963. 600 Hound Dogs were produced from 1957 to 1963. Twenty-three Hound Dog-equipped B-52 squadrons were operational by 30 June 1962, and by August 1963 29 SAC wings were operational with the AGM-28. Hound Dog production ended in March 1963 and the number of operational missiles declined in the late 1960s and early 1970s to about 308 in 1976.
     After thirteen years of service in the Strategic Air Command, the last Hound Dog missile was removed from alert on 30 June 1975. Nearly three years later, on 15 June 1978, the 42d Bombardment Wing, Loring AFB, Maine, destroyed the last last Hound Dog missile and removed it from the SAC inventory.
