In short: Developed in just 30 months, the AGM-28 Hound Dog was a nuclear-armed cruise missile designed to penetrate Soviet air defenses. Surprisingly, the Strategic Air Command discovered they could use the missile's turbojet engine to provide extra thrust for the B-52 bombers carrying them, helping the planes escape airbases faster.

Conceived in 1959 as a temporary standoff weapon until the GAM-87 Skybolt was ready, the Hound Dog became a mainstay of the U.S. nuclear deterrent for 15 years. It was designed to neutralize Soviet surface-to-air missile sites, which threatened the viability of the American bomber fleet. By launching the missile from outside the range of enemy defenses, B-52 crews could strike targets while remaining at a safe distance. The weapon was powered by a Pratt & Whitney J52-P-3 turbojet, optimized for a short, high-power flight life of six hours, after which it was expected to self-destruct.

The missile's versatility was a key feature. It could be launched at various altitudes and featured a 'dogleg' flight profile designed to lure enemy fighters away from the primary target. Beyond its offensive role, the Hound Dog served a unique logistical purpose. SAC developed procedures to run the missile's engine while it remained attached to the B-52's pylons, effectively turning the cruise missile into a booster rocket that allowed heavily loaded bombers to take off and climb more rapidly during a potential surprise attack.

Technological evolution defined the Hound Dog's service life. Early models relied on inertial navigation corrected by a star tracker, but later versions incorporated radar-absorbent materials to reduce their radar cross-section and added terrain-following capabilities. Although the U.S. tested advanced guidance systems like Terrain Contour Matching (TERCOM) and anti-radiation seekers, the missile was never used in combat. By the time the last Hound Dog was retired in 1978, it had been superseded by newer systems like the AGM-86 ALCM, leaving behind a legacy of innovation that bridged the gap between early cruise missiles and modern precision weaponry.
