RNAD Coulport

The Royal Armaments Depot at Coulport, eight miles from Faslane, is responsible for the storage, processing, maintenance and issue of key elements of the UK’s Trident Deterrent Missile System and the ammunitioning of all submarine-embarked weapons.

It also stores conventional armaments for Royal Navy vessels.

Because of the nature of its work, the site is subject to the most stringent external security regulators who authorise the depot to process nuclear weapons and provide support to nuclear submarines berthed at the Explosive Handling Jetty.
