The Polaris missile was a submarine-launched, two-stage solid-fuel nuclear-armed ballistic missile (SLBM) built during the Cold War by Lockheed for the United States Navy. It was designed to be used as part of the US Navy's contribution to the United States' arsenal of nuclear weapons, replacing the Regulus cruise missile. Known as a Fleet Ballistic Missile (FBM), it first flew from Cape Canaveral on January 7, 1960.
Following the Polaris Sales Agreement in 1963 Polaris missiles were also carried on UK submarines between 1968 and the mid 1990s.
Polaris began to be replaced in the US Navy by Poseidon beginning in 1972. In the 1980s both were replaced by Trident I.
