The UK government has confirmed a further £8.4 billion investment in its nuclear submarine programme, reinforcing its commitment to maintaining the country’s strategic deterrent. The announcement was made by Prime Minister Andy Burnham during a visit to Barrow-in-Furness, Cumbria, where the submarines are being built. The funding is intended to support tens of thousands of jobs and around 22,000 apprenticeships across the UK’s defence supply chain.

The new investment forms part of the ongoing development of four nuclear submarines, with the first, HMS Dreadnought, expected to enter service in the 2030s. Of the total sum, £5.9 billion will be allocated to BAE Systems in Barrow, with the remaining £2.5 billion distributed across other suppliers nationwide.

Burnham emphasized the importance of ensuring that the funding benefits British workers and industries, particularly in regions that have faced long-term economic challenges. “Keeping this country safe is the first responsibility of any government,” he stated, adding that the focus would be on “British money, spent on British workers, British firms and British skills.”

Defence Secretary Wes Streeting also highlighted the critical role the submarines play in the UK's national security, describing them as "the ultimate deterrent to our adversaries in an increasingly dangerous world."

However, the announcement drew criticism from opposition Conservative figures who characterized the £8.4 billion as part of previously agreed funding. Shadow Defence Secretary James Cartlidge noted that the expenditure had been outlined in the Defence Investment Plan (DIP) approved under Sir Keir Starmer’s administration. While welcoming progress on the Dreadnought programme, Cartlidge expressed concern over a lack of clarity regarding other elements of the Strategic Defence Review, in particular the planned procurement of up to 12 attack submarines.

Cartlidge further criticized Burnham for not endorsing a clear path toward meeting the NATO defence spending target of 3% of GDP, a commitment urged by former Chancellor John Healey upon his resignation as Defence Secretary.

The Green Party also voiced opposition to the focus on nuclear weapons, with Dr. Ellie Chowns describing the investment as a misallocation of resources. “For families across Britain, real security does not mean pouring billions into weapons that must never be used,” she said. Chowns advocated for a shift towards investment in the clean and green economy, warning against dependence on what she termed "cold-war era tech."

The renewed funding signals continued government prioritization of the UK’s nuclear deterrent amid evolving global security challenges, while debates persist over defence spending priorities and strategic direction.
