The investment provides a long-term boost to UK defence contractors, particularly BAE Systems and Rolls-Royce, supporting jobs and supply chains. However, the lack of new funding and ongoing uncertainty about overall defence spending may limit positive market sentiment.
UK Prime Minister Andy Burnham announced an £8.4 billion investment for the Dreadnought-class nuclear submarine programme, aimed at preparing HMS Dreadnought for service by the 2030s. The funding will support the construction of four submarines to replace the Vanguard-class, with £5.9 billion going to BAE Systems and £2.5 billion to the supply chain. The investment is expected to sustain 47,000 jobs and create 22,000 apprenticeships by 2035. The announcement follows the Defence Investment Plan published under former PM Keir Starmer, which set total defence investment at £298 billion over four years. Critics, including shadow defence secretary James Cartlidge, noted the funding was previously confirmed and questioned the lack of detail on attack submarine procurement and the pathway to 3.5% GDP defence spending by 2035. The submarines will be powered by Rolls-Royce nuclear propulsion systems and carry Trident 2 D5 missiles.
