USS George Washington, the first U.S. missile submarine, successfully launched the first Polaris missile from a submerged submarine on July 20, 1960. The A-2 version of the Polaris missile was essentially an upgraded A-1, and it entered service in late 1961. It was fitted on a total of 13 submarines and served until June 1974.
Polaris missile launch from HMS Revenge in 1983 Sixteen tubes for Polaris A3 Submarine-launched ballistic missiles were carried, in two rows of eight. [ 4 ] The missiles had a range of 2,500 nautical miles (2,900 mi; 4,600 km), [ 7 ] [ 8 ] and each missile could carry three 200 kt (840 TJ) nuclear warheads. [ 9 ]

The construction was unusual in that the bow and stern were constructed separately before being assembled together with the American-designed missile compartment. The design was a modification of the Valiant-class fleet submarine, but greatly extended to incorporate the missile compartment between the fin and the nuclear reactor. The length was ...
The UGM-73 Poseidon missile was the second US Navy nuclear-armed submarine-launched ballistic missile (SLBM) system, powered by a two-stage solid-fuel rocket.It succeeded the UGM-27 Polaris beginning in 1972, bringing major advances in warheads and accuracy.
The Navy's Special Projects Office, charged with developing the Polaris-Submarine weapon system and the Fleet Ballistic Missile capability, has developed a statistical technique for measuring and forecasting progress in research and development programs. This program evaluation and review technique (code-named PERT) is applied as a decision ...
The ship was assigned to the 10th Submarine Squadron (United Kingdom) where it operated as the first of the UKs new Polaris based nuclear deterrent. [2]Her Polaris system was updated in 1984 with the Chevaline IFE (Improved Front End) that included two new warheads and re-entry bodies and penaids, super-hardened to resist ABM attack, replacing the original three ET.317 warheads.
The United States had deployed nuclear weapons aboard submarines for the purpose of deterrence since 1959, using the SSM-N-8 Regulus cruise missile.However, this was intended to act merely as a stop-gap, as the Regulus was limited both by its size – the greatest number of missiles capable of being taken to sea was five aboard USS Halibut – range and speed, as well as the fact that the ...
