What it is

A two-stage missile guided by ground radar commands, with a fragmentation warhead detonated near the bomber. Deployed in 1954 around American cities, it was the first operational guided surface-to-air system in the Western world.

The Germans developed the Wasserfall earlier, which did not reach service, and the USSR deployed the S-25 Berkut in 1955; the Nike Ajax's primacy is as the first operational system in the West.

What it led to

  • the Soviet SA-2 and the Hawk and Patriot missiles
  • integrated air-defence systems
  • deterrence against bombers
