HMS Sovereign was a nuclear-powered, attack submarine (SSN). Construction began on 18th September 1970. She launched on 17th February 1973, and commissioned on 11th July 1974.

The Cold War resulted in the need for improved anti-submarine warfare (ASW) capability in order to keep track of Soviet submarines. The Royal Navy realised that their own submarines could be successfully used to perform this role. This led to the evolution of SSN attack submarines.
