Project Nike was a U.S. Army project proposed in May 1945 by Bell Laboratories to develop a line-of-sight anti-aircraft missile system. By 1953 the project delivered the United States' first operational anti-aircraft missile system, the Nike Ajax. Many technologies and rocket systems used for developing the Nike Ajax were re-used in other projects, many given the "Nike" name. The missile's first-stage solid rocket booster became the basis for many types of rockets, including the Nike Hercules and Nike Smoke.
