Hercules Missile on launcher

And off it goes


Development of the Nike Hercules took place in the early 1950s and deployment commenced in 1958. A total of 145 missile batteries were deployed. Most of which were converted Nike Ajax units. Deactivation of Nike Hercules batteries, in the United States, commenced in the early 1970s and was completed by 1975, with the exception of batteries remaining in Alaska and Florida. These batteries were deactivated in the late 1970s. Foreign countries, mainly NATO allies, deployed this system as well.


During the Cold War there were many aspects to the air defense of Canada and the United States. Most of the public did not know of these sites or duties, but they were a 24/7 operation and a vital part of the air defense network. Nike Missile Systems were the last line of defense and were placed around strategic targets or large cities, which had strategic value.
