The UGM-27 Polaris missile was a two-stage solid-fueled nuclear-armed submarine-launched ballistic missile (SLBM). As the United States Navy 's first SLBM, it served from 1961 to 1980. In the mid-1950s the Navy was involved in the Jupiter missile project with the U.S. Army , and had influenced the design by making it squat so it would fit in ...
The Gilbert U-238 Atomic Energy Lab is a toy lab set designed to allow children to create and watch nuclear and chemical reactions using radioactive material. The Atomic Energy Lab was released by the A. C. Gilbert Company in 1950.
The US Navy's first nuclear-powered submarine, USS Nautilus became operational on 17 January 1955. [17] One reason the Royal Navy lagged behind its American counterpart was the lack of a high-ranking champion who would push nuclear submarine development. [18] This changed when Admiral Lord Mountbatten became First Sea Lord in April 1955. [19]
Bettis Atomic Power Laboratory, operated by Westinghouse, developed the basic reactor plant design used in Nautilus after being given the assignment on 31 December 1947 to design a nuclear power plant for a submarine. [14] Nuclear power had a crucial advantage in submarine propulsion because it is a zero-emission process that consumes no air ...
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 130 metres (430 ft), breadth 10.1 metres (33 ft), height 9 metres (30 ft) and the displacement 8,400 long tons (8,500 t) submerged and 7,600 long tons (7,700 t ...
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.
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] Defensive armament consisted of six 533-millimetre (21 in) torpedo tubes. [4]
The base serves as home base to Britain's fleet of Vanguard-class nuclear-powered and nuclear-armed submarines, as well as conventionally armed nuclear-powered submarines, supported by the 43 Commando Fleet Protection Group Royal Marines. [24] In command of HMNB Clyde is the Naval Base Commander (Clyde), Commodore Sharon Malkin.
