Project Nike Project Nike, (Greek: Νίκη, "Victory", pronounced [nǐːkɛː]), was a U.S. Army project, proposed in May 1945 by Bell Laboratories, to develop a line-of-sight anti-aircraft missile system. The project delivered the United States' first operational anti-aircraft missile system, the Nike Ajax, in 1953. A great number of the technologies and rocket systems used for developing the Nike Ajax were re-used for a number of functions, many of which were given the "Nike" name (after Nike, the goddess of victory from Greek mythology).
