I am today announcing the largest investment in the United Kingdom’s naval bases since the end of the Cold War.

As set out in the Strategic Defence Review, improving readiness and strengthening our ability to generate maritime forces at pace is central to the Government’s approach to national security in an increasingly uncertain world. Our naval bases are critical national infrastructure, and their condition directly affects the availability, credibility and effectiveness of the Royal Navy.

As confirmed in the Defence Investment Plan, I can announce today that the Government is delivering Project Royal Oak, which is the collective name we have given to the extensive strategic investment we have committed for improvements to His Majesty’s Naval Base Clyde in Faslane, His Majesty’s Naval Base Devonport, and His Majesty’s Naval Base Portsmouth. Collectively, this represents approximately £26bn^[1] of investment over the next ten years to increase the readiness, availability and lethality of the Royal Navy.

• Investments at HMNB Clyde are governed by the Clyde Transformation Programme. This will see a multi-decade, multi-billion-pound transformation of the site covering everything from dock infrastructure, training and accommodation facilities. It will also include Programme Euston which will see three new floating docks and shoreside infrastructure for submarine maintenance with a renewed focus on asset management that will sustain infrastructure over the long term. There will also be a separate, offsite engineering facility established to boost maintenance capacity. This comprises £15.1bn over the next decade.
• In the South-West, forecast investment of £7.1bn over the next decade at HMNB Devonport will deliver major upgrades and new and replacement infrastructure across the Naval Base and Dockyard. Devonport is the UK centre for submarine deep maintenance and supports the Continuous At Sea Deterrent, submarines, ships, sailors and the Royal Marine Commando Force. The programme includes upgrades to 15 Dock, modernisation of 10 Dock, work on 14 Dock to enable submarine defueling to recommence, and wider renewal and maintenance across the site. This reflects both previous under-investment in infrastructure and a changing operational requirement.
• On the Solent, forecast investment of £3.9bn at HMNB Portsmouth will ensure recovery from years of disinvestment alongside vital modernisation to meet the emergent demands of a Hybrid Navy which is maximised for warfighting readiness. This includes Project Bentham to upgrade jetties, berthing and support systems; a Capability Accelerator to support the Hybrid Navy and fast-track technological development; a Skills Development Centre for apprentice and adult learning; and expansion of the Royal Navy Warfighting Centre.

Taken together, these projects will modernise docks, jetties, engineering facilities and support infrastructure across the naval estate, ensuring our bases are resilient, capable and fit to support current and future fleets.

In these uncertain times, this investment will ensure that the Royal Navy is better placed to meet the challenges it faces, strengthen deterrence, and protect the United Kingdom’s security and interests at home and overseas. The House will be kept informed as these projects progress.
