The submarine base encompasses a number of separate sites, the primary two being: Faslane, 25 miles from Glasgow; RNAD Coulport, beside Loch Long, 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. The naval shore establishment at Faslane is HMS Neptune, Naval personnel appointed to the base who do not belong to a seagoing vessel make up Ship's Company. Both the Gare Loch and Loch Long are sea lochs extending northwards from the Firth of Clyde. The base serves as home base to Britain's fleet of nuclear-powered and nuclear-armed submarines, as well as conventionally armed nuclear-powered submarines, supported by the 43 Commando Fleet Protection Group Royal Marines. In command of HMNB Clyde is the Naval Base Commander (Clyde), Commodore Donald Doull, who succeeded Commodore Mark Gayfer in Summer 2018. The base is home to a number of lodger units including Flag Officer Scotland and Northern Ireland (FOSNI) (who is also Rear Admiral Submarines), the Northern Diving Group and the Scottish Headquarters of the Ministry of Defence Police. It is base to 3,000 service personnel, 800 of their families and 4,000 civilian workers, largely from Babcock Marine, forming a major part of the economy of Argyll and Bute and West Dunbartonshire. By 2020 all 11 Royal Navy submarines will be based on the Clyde at Faslane, seeing the number of people directly employed at the base rising to 8,200. In 2018, the Secretary of State for Scotland at the time, David Mundell said: "The UK’s entire submarine fleet will be based at Faslane by 2020. This will reinforce Scotland’s vital role in protecting our country, and guarantee skilled, secure jobs on the Clyde for years to come." Safety and accidents at Faslane Exercise Evening
