Her Majesty's Naval Base, Devonport (HMNB Devonport), is one of three operating bases in the United Kingdom for the Royal Navy (the others being HMNB Clyde and HMNB Portsmouth). HMNB Devonport is located in Devonport, in the west of the city of Plymouth. Having begun as Royal Navy Dockyard in the late-17th century, it is now the largest naval base in Western Europe and is the sole nuclear repair and refuelling facility for the Royal Navy. Shipbuilding ceased at Devonport in the early 1970s, but ship maintenance work has continued: the now privatised maintenance facilities are operated by Babcock Marine who took over in 2007.
HM Naval Base Devonport is the home port of the Devonport Flotilla which includes the largest ship in the Royal Navy HMS Ocean and the Trafalgar-class submarines. Devonport will no longer be used as a base for attack submarines after these move to Faslane by 2017, and the Type 45 destroyers are based at Portsmouth. However, Devonport retains a long-term role as the dedicated home of the amphibious fleet, survey vessels and half the frigate fleet.
