The British government awarded a $7.8 billion contract to BAE Systems on July 29, 2026, to continue construction of the Royal Navy’s next-generation Dreadnought-class nuclear-armed submarines.

The contract forms part of a wider $11.2 billion government funding package approved by Parliament to support Britain’s nuclear deterrent program through the next decade. Prime Minister Andy Burnham announced the investment during a visit to BAE Systems’ shipyard in Barrow-in-Furness, northwest England, where all four Dreadnought-class submarines are being built.

The new funding will advance construction of the four submarines, HMS Dreadnought, HMS Valiant, HMS Warspite and HMS King George VI, which are expected to enter service in the early 2030s and gradually replace the Royal Navy’s aging Vanguard-class fleet.

Supporting the UK’s Nuclear Deterrent

The Dreadnought-class submarines will assume responsibility for Britain’s Continuous At-Sea Deterrent (CASD), ensuring the country maintains an uninterrupted nuclear deterrent patrol capability, in place since 1969 under Operation Relentless.

The vessels will be the largest and most advanced submarines ever built for the Royal Navy. Each submarine will displace more than 17,000 tons, measure over 500 feet (152 meters) in length and carry a crew of around 130 personnel. Although slightly larger than the Vanguard-class submarines they replace, they have the same mission: maintaining the UK’s strategic nuclear deterrent.

The latest contract covers continued production of all four submarines. Construction of HMS Dreadnought will continue toward sea trials before its planned entry into service early next decade. Funding will also support completion of HMS Valiant through to sea trials while advancing fabrication and outfitting work on HMS Warspite and HMS King George VI.

The program is being delivered by BAE Systems in partnership with the Ministry of Defense’s Defense Nuclear Enterprise.

Broader Defense Investment

The $7.8 billion contract represents the fourth major production phase of the Dreadnought program and is included within a broader $11.2 billion package approved by Parliament to maintain and renew Britain’s nuclear deterrent.

Government officials said the investment is intended not only to modernize the Royal Navy’s submarine fleet but also to strengthen the UK’s defense industrial base and support thousands of skilled manufacturing jobs across the country.

Prime Minister Burnham said the investment would strengthen both national security and economic development. “Keeping this country safe is the first responsibility of any government – but security is not only about what we build, it is about who builds it, and who benefits from it,” Burnham said.

“The submarines produced in Barrow will protect Britain for decades to come, and the 47,000 jobs and apprenticeships will change lives both in this town and in dozens of places like it.”

Defense Secretary Wes Streeting described the submarines as central to Britain’s national security strategy.

“Our nuclear-armed submarines are essential to keeping the UK secure, acting as the ultimate deterrent to our adversaries in an increasingly dangerous world,” Streeting said. “This milestone investment breathes new life into Barrow’s historic traditions and secures our commitment to deliver Dreadnought Class submarines by backing British industry.”

Boost for British Defense Industry

Beyond its military significance, the Dreadnought program is one of Britain’s largest industrial projects, supporting a nationwide supply chain involving thousands of companies.

According to the government, the UK’s Defense Nuclear Enterprise currently supports around 47,000 jobs across the country, including more than a quarter based in Barrow-in-Furness. Around 8,000 jobs are linked to submarine refit work in Devonport, while another 5,000 are based at Faslane in Scotland, home to Britain’s submarine fleet.

Employment across the nuclear enterprise is expected to increase to around 65,000 jobs by 2030, while approximately 22,000 apprenticeships are planned by 2035.

More than 6,000 UK-based companies contribute to the submarine supply chain. BAE Systems said about 30,000 jobs nationwide are currently supported by the Dreadnought program alone, including more than 7,000 employees working directly on the submarines.

During its most recent financial year, the company spent approximately $1.7 billion through the Dreadnought supply chain. Total expenditure has reached around $11.8 billion across more than 1,500 British suppliers.

The company has also invested about $1.3 billion in expanding and modernizing its Barrow shipyard, increasing its workforce from around 11,000 employees to approximately 16,000 over the past four years.

Government officials said productivity at the Barrow shipyard has improved by about 40% over the past three years, reflecting continued investment in facilities, technology and workforce development.

Long-term strategic capability

The Dreadnought program is considered one of the UK’s most important long-term defense projects, ensuring Britain maintains an independent sea-based nuclear deterrent for decades.

“The Dreadnought program is of vital strategic importance to the UK, underpinning the security of our nation and our allies for decades to come,” BAE Systems Chief Executive Charles Woodburn said.

“Its delivery depends on the strength of our national industrial base, with thousands of skilled workers right across the country playing their part in the mission to deliver this critical capability to the Royal Navy.”

The investment also reinforces Barrow-in-Furness’ position as the center of Britain’s submarine construction industry. In 2025, King Charles III granted the town Royal Port status in recognition of its longstanding contribution to UK defense and submarine manufacturing.

Alongside shipbuilding activities, BAE Systems continues to invest in local education, skills development and community projects through the Team Barrow partnership and the $266 million Barrow Transformation Fund.

With construction progressing on all four submarines, the Dreadnought program is expected to remain one of Britain’s largest defense and industrial initiatives throughout the 2030s, ensuring the Royal Navy can sustain its continuous nuclear deterrent while supporting tens of thousands of highly skilled jobs across the United Kingdom.
