HMNB Clyde

HMNB Clyde

Her Majesty's Naval Base (HMNB) Clyde (also HMS Neptune) is one of three operating bases in the United Kingdom for the Royal Navy (the others being HMNB Devonport and HMNB Portsmouth). It is the service's headquarters in Scotland and is best known as the home of the United Kingdom's strategic nuclear deterrent, in the form of nuclear submarines armed with Trident missiles.

HMNB Clyde lies on the eastern shore of Gare Loch in Argyll and Bute, Scotland, to the north of the Firth of Clyde and 25 mi (40 km) west of the city of Glasgow. The submarine base encompasses a number of separate sites, the primary two being:

• Faslane, 25 miles from Glasgow;
• RNAD Coulport, beside Loch Long, 8 mi (13 km) west of Faslane.

Faslane is also a Defence Equipment and Support site, operated in dual site organisation with Great Harbour, Greenock, by Babcock Marine and Technology, and managed by Serco Denholm.
