Submarine Delivery Agency

The SDA is an executive agency of the Ministry of Defence (MOD). We manage the procurement, in-service support, and disposal of UK nuclear submarines. These are some of the most complex equipment in the world. Our mission is to deliver available and capable submarines for the Royal Navy in defence of the nation. We deliver capabilities to the Royal Navy that are essential to the Continuous at Sea Deterrent (CASD) - the cornerstone of our national security. Show more Show less
