Main Body
On 14 July 2026, HM Government announced a £26 billion, 10-year programme to modernise docking facilities, waterfront infrastructure and related works at HMNB Clyde, HMNB Devonport and HMNB Portsmouth. HM Government described the programme as the UK’s largest naval infrastructure effort since the Cold War and said it was intended to strengthen Royal Navy readiness.
According to HM Government, the investment was directed at the Royal Navy’s three main naval bases and would focus on waterfront and docking capacity needed to sustain naval operations. HM Government also said the programme would create thousands of skilled jobs, particularly in Scotland and the South West of England.
The announcement followed the wider UK defence funding plan, as GPS previously reported. On 30 June 2026, HM Government said it had added £15 billion for the Armed Forces, taking the Defence Investment Plan to £298 billion and setting annual defence spending on a path toward nearly £80 billion by 2029.
The practical significance was that HM Government linked naval infrastructure renewal to operational readiness and skilled employment. HM Government had also tied the wider June defence package to drones, nuclear deterrent upgrades and next-generation fighter aircraft, placing the naval base works within a broader programme to prepare the Armed Forces for future conflict.
