The Resolution class was a class of four nuclear ballistic missile submarines (SSBN) built for the Royal Navy as part of the UK Polaris programme. Each submarine was armed with up to 16 UGM-27 Polaris A-3 nuclear missiles.
A submarine-launched ballistic missile (SLBM) is a ballistic missile capable of being launched from submarines. Modern variants usually deliver multiple independently targetable reentry vehicles (MIRVs), each of which carries a nuclear warhead and allows a single launched missile to strike several targets. Submarine-launched ballistic missiles operate in a different way from submarine-launched cruise missiles.
A ballistic missile submarine is a submarine capable of deploying submarine-launched ballistic missiles (SLBMs) with nuclear warheads. These submarines became a major weapon system in the Cold War because of their nuclear deterrence capability. They can fire missiles thousands of kilometers from their targets, and acoustic quieting makes them difficult to detect, thus making them a survivable deterrent in the event of a first strike and a key element of the mutual assured destruction policy of nuclear deterrence.
The George Washington class was a class of nuclear-powered ballistic missile submarines deployed by the United States Navy. George Washington, along with the later Ethan Allen, Lafayette, James Madison, and Benjamin Franklin classes, comprised the "41 for Freedom" group of submarines that represented the Navy's main contribution to the nuclear deterrent force through the late 1980s.
The James Madison class of submarine was an evolutionary development from the Lafayette class of fleet ballistic missile submarine. They were identical to the Lafayettes except for being initially designed to carry the Polaris A-3 missile instead of the earlier A-2. This class, together with the George Washington, Ethan Allen, Lafayette, and Benjamin Franklin classes, composed the "41 for Freedom" that was the Navy's primary contribution to the nuclear deterrent force through the late 1980s. This class and the Benjamin Franklin class are combined with the Lafayettes in some references.
The Delfinen-class submarines were the first class of submarines constructed for the Royal Danish Navy following World War II. They were designed and built within Denmark, with first three boats of the class financed by Denmark. The fourth was financed by the United States under the Cost Share program. Constructed between 1956 and 1963, the class comprising four submarines entered service in 1961 and the last taken out of service in 1990. Replaced by the Norwegian Kobben class, three of them were scrapped while a fourth was converted into a museum ship and remains on display at the Aalborg Maritime Museum.
HMS Onyx was an Oberon class submarine of the Royal Navy.
A submarine-launched cruise missile (SLCM) is a cruise missile that is launched from a submarine. Current versions are typically standoff weapons known as land-attack cruise missiles (LACMs), which are used to attack predetermined land targets with conventional or nuclear payloads. Anti-ship cruise missiles (ASCMs) are also used, and some submarine-launched cruise missiles have variants for both functions.
The Le Redoutable-class submarine was a ballistic missile submarine class of the French Navy. In French, the type is called Sous-marin Nucléaire Lanceur d'Engins (SNLE), literally "Missile-launching nuclear submarine". When commissioned, they constituted the strategic part of the naval component of the French nuclear triad, then called Force de frappe.
The latest HMS Warspite was the third of Britain's nuclear-powered submarines, and the second of the Valiant class. After entering service in 1967 she collided with a Soviet submarine the following year. A mechanical failure associated with the submarine's nuclear reactor in 1991 led to the boat being laid up at HMNB Devonport where she awaits disposal.
HMS Sealion (S07) was a Porpoise-class submarine.
HMS Repulse (S23) was a Resolution-class ballistic missile submarine of the Royal Navy.
HMS Renown (S26) was the third of the Royal Navy's Resolution-class ballistic missile submarines.
HMS Rorqual (S02) was a Porpoise-class submarine launched in 1956. She was built by the Vickers shipyard in Barrow-in-Furness, Cumbria, England. The boat was named for both the rorqual, a family of whale, and the earlier Second World War-era submarine of the same name.
The Natsushio-class submarines were a pair of submarines constructed and operated by the Japan Maritime Self-Defense Force during the Cold War. They were a development of the Hayashio-class submarines and are sometimes considered the same class. They were small and limited in capability but were thought to be a successful class. They entered service in 1963–1964 and were deleted in 1978.
HMS Lowestoft was a Rothesay-class or Type 12 class anti-submarine frigate of the British Royal Navy. Lowestoft was reconstructed in the late 1960s to largely the same pattern as the third group of Leander-class frigates, with new radar and fire control and a hangar and pad for a Westland Wasp helicopter for longer range, anti-submarine, engagement. In the late 1970s it was converted as the prototype towed array frigate for the Royal Navy, but retained its full armament. Lowestoft was sunk as a target on 8 June 1986 by HMS Conqueror using a Tigerfish torpedo. She was the last Royal Naval target to be sunk still displaying her pennant number.
HMS Whitby was a Whitby-class or Type 12 anti-submarine frigate of the Royal Navy of the United Kingdom built by Cammell Laird and Co Ltd, Birkenhead. She was launched on 2 July 1954 and commissioned on 10 July 1956.
HMS Cachalot (S06) was a Porpoise-class submarine. Her keel was laid down on 1 August 1955 by Scotts Shipbuilding and Engineering Company at Greenock. She was launched on 11 December 1957, and commissioned on 1 September 1959.
HMS Narwhal (S03) was a Porpoise-class submarine of the Royal Navy. She was launched on 25 October 1957.
HMS Spearhead was a S-class submarine of the third batch built for the Royal Navy during World War II. She survived the war and was sold to Portugal. She was scrapped in 1967.
