About Submarine Delivery Agency (SDA)

The Submarine Delivery Agency (SDA) is an Executive Agency of the UK's Ministry of Defence (MOD). They were established in April 2018 to manage the procurement, in-service support and disposal of UK nuclear submarines, which are some of the most complex equipment in the world. They deliver capabilities to the Royal Navy that are essential to the Continuous at Sea Deterrent (CASD), which is the cornerstone of our national security.
