Vanguard Class Submarine Life Extension Programme
UK (maintenance and refit) · Ongoing (original service life 25 years, extended to bridge gap to Dreadnought class) · £560 million (for HMS Victorious refit); part of a larger £3.5 billion FMSP contract for through-life support of Vanguard and Astute classes.
The judgement call
Account action unavailableThe life extension programme is crucial to bridge the gap until the Dreadnought class submarines enter service, ensuring the continuity of the UK's nuclear deterrent. - These complex refits involve extensive work on the reactor, propulsion, and combat systems. - The programme highlights the significant investment required to maintain strategic defence capabilities over decades.
Key engineering challenges
Extending the operational life of complex nuclear-powered submarines safely and effectively. - Upgrading critical systems and components to ensure continued reliability and capability. - Managing the refit and maintenance schedules to maintain continuous at-sea deterrence. - Addressing material fatigue and obsolescence issues in ageing platforms.
