Royal Navy: Nuclear Submarines

Contribution

My Lords, the Royal Navy has a fleet of nine submarines currently in service. It operates four Vanguard class nuclear-powered and nuclear-armed submarines in Operation Relentless, the continuous at-sea deterrent, which has been successfully maintained for over 56 years. The Vanguard class will be sequentially replaced by four Dreadnought class submarines, which will enter service in the 2030s. Additionally, five Astute class nuclear-powered and conventionally armed submarines are in service, with two more under construction.
