Submarine squadron

A submarine squadron (SUBRON) is a naval formation or unit in such states such as the United Kingdom, United States, and Russia/Soviet Union. In France the equivalent unit is the escadrille des sous-marins nucléaires d'attaque (ESNA), part of the French submarine forces (and before the Second World War, escadrilles de sous-marins).

Submarine flotillas became submarine divisions in 1952.HMS Finwhale was a Porpoise-class submarine belonging first to Faslane's 3rd Submarine Squadron and then to Singapore's 7th Submarine Squadron (United Kingdom).

From the early 1960s the structure was:

In 1971 HMNB Clyde at Faslane in Scotland was home to the Third Submarine Squadron of Nuclear Fleet and Diesel Patrol Submarines, 'the fighters', and the 10th Submarine Squadron consisting of the four Polaris submarines, 'the bombers'. The Base also conducted the training of all submarines before they joined their Squadrons and this was known as 'work up'. On the decommissioning of the Polaris submarines the 10th Submarine Squadron re-equipped with Vanguard-class ballistic missile submarines.

1st Submarine Squadron was located at HMS Dolphin during the early 1990s. In 2001, the five Swiftsure-class submarines were part of the 1st Submarine Squadron based at Faslane and the seven Trafalgar-class boats were with the Second Submarine Squadron at Devonport.
