Watch the simulated launch of a nuclear shell from "Atomic Annie", an American atomic gun, during Exercise Keystone in September 1954. “Atomic Annie” was the US Army’s largest artillery weapon at the time. It weighed 85 tons, but was fully mobile and manned like any other piece of artillery. The simulation was carried out during a period when NATO had decided to shift the emphasis of its defence policy to greater dependency on the use of nuclear weapons.
