The MIM-3 Nike Ajax was the first operational surface-to-air missile (SAM) system deployed by the United States, developed in the late 1940s and early 1950s to defend against the threat of high-altitude Soviet bombers during the Cold War. Designed by Bell Laboratories and Western Electric, it used a two-stage propulsion system with a solid-fuel booster and a liquid-fuel sustainer, giving it the ability to reach targets at high speeds and altitudes. Equipped with three separate high-explosive fragmentation warheads, the Nike Ajax was intended to maximize the probability of destroying large, heavily built strategic bombers.

Production of the Nike Ajax began in 1951, with thousands of missiles manufactured and deployed at over 200 sites across the United States and allied nations. The system officially entered service in 1954, quickly becoming the backbone of continental air defense. Despite its effectiveness, the missile had limitations, including reliance on liquid fuel that was hazardous to handle and limited effectiveness against maneuvering or supersonic targets. These shortcomings prompted the development of its successor, the nuclear-capable Nike Hercules.

The Nike Ajax gained notoriety as both a pioneering defense system and a reflection of Cold War anxieties. While it was never used in combat, its widespread deployment symbolized the seriousness of the perceived Soviet bomber threat and represented a major step forward in missile defense technology. By the early 1960s, it was gradually phased out in favor of the more advanced Nike Hercules, yet its legacy endures as the foundation of modern surface-to-air missile defense systems.
