Britain backs BAE Systems and Rolls-Royce expansion with £6 billion plan to start SSN-AUKUS production in 2027 and double submarine output

The UK government has committed £6 billion to support BAE Systems and Rolls-Royce in expanding submarine production capacity, with SSN-AUKUS construction scheduled to begin in 2027 and a stated objective of doubling submarine output. The investment will fund facility upgrades at Barrow-in-Furness and propulsion manufacturing at Rolls-Royce's Derby and Bristol sites. The plan is central to Britain's obligations under the AUKUS trilateral agreement and represents the largest single commitment to UK submarine industrial capacity in decades, with implications for both domestic naval procurement and Australia's future submarine fleet.
