The first of the UK Royal Navy's (RN's) Vanguard-class nuclear-powered ballistic missile submarines (SSBNs) will begin its Life Extension (LIFEX) programme in 2015 as part of a planned deep maintenance period at Babcock's Devonport dockyard.

HMS Vanguard will be the first of the four Vanguard-class Trident ballistic missile boats to commence the LIFEX programme. This is intended to extend the boats' service life so as to enable the RN to maintain continuous at-sea deterrence (CASD) until the planned Successor boats enter service.

The Successor SSBN programme was confirmed in the 2010 Strategic Defence and Security Review (SDSR), with a class of four boats currently planned.
