This is a mockup of the Polaris A-3, the third and last version of the U.S. Navy's first generation submarine-launched ballistic missile. It was deployed between 1964 and 1981. Sixteen were carried on each Polaris submarine. The A-3 had a range of 2,500 nautical miles and carried three W58 thermonuclear warheads, each with a yield of 200 kilotons. Lockheed Missiles and Space made this mockup and the Navy's Bureau of Weapons donated it to NASM in 1962.
Transferred from the United States Navy, Bureau of Weapons.
