Faslane Naval Base , aka HMS Neptune, is a Royal Navy base situated on the River Clyde in Scotland. The base serves as home base to the UK's fleet of Trident nuclear armed submarines, as well as conventional nuclear submarines. Nearby Coulport naval base acts as the storage facility for Trident.
Faslane was first constructed used as a base in World War II. During the 1960s, the United Kingdom began negotiations with the United States of America regarding the purchase of a Polaris nuclear missile system to be fired from 5 specially constructed submarines. In the end, only four were constructed:
- HMS Resolution
- HMS Repulse
- HMS Renown
- HMS Revenge
- HMS Vanguard
- HMS Victorious
- HMS Vigilant
- HMS Vengeance
Faslane is also home to the Royal Navy's other classes of submarine, including the fleet of hunter killer submarines: the Trafalgar class; and the Swiftsure class.
