Reports that every British Astute-class attack submarine is out of service have raised concerns about the Royal Navy’s ability to protect undersea cables and support the U.K.’s nuclear deterrent.

Britain’s entire fleet of Astute-class attack submarines is reportedly out of service and awaiting maintenance or repair work, raising fresh questions about the Royal Navy’s readiness as Russian naval activity increases around British waters.

The reported status of the fleet was highlighted in an X post, which pointed to concerns that the Royal Navy’s hunter-killer submarines are currently unable to deploy.

According to the Daily Mail, all five of Britain’s Astute-class submarines are laid up while awaiting maintenance and other repairs.

“In a fresh humiliation for Britain’s Armed Forces, all five of its Astute class submarines are currently laid up awaiting maintenance and other repair work,” the Daily Mail reported.

“Military experts have also warned that the Navy’s lack of available nuclear-powered attack submarines – which carry up to 38 Spearfish torpedoes and a battery of Tomahawk missiles – leaves the UK’s sub-sea internet and power cables dangerously vulnerable to sabotage by [Russia],” the report said.

The concern is not limited to the attack submarines’ offensive role. The Astute-class boats also help protect Britain’s larger Vanguard-class submarines, which carry Trident ballistic nuclear missiles and form the sea-based leg of the United Kingdom’s nuclear deterrent.

The reported submarine problems come as the Royal Navy is facing additional questions over the condition of major vessels. The Daily Mail noted that the revelations followed a report that one of Britain’s flagship aircraft carriers, valued at 3.5 billion pounds, had broken down again and been forced into port in Norway for repairs.

“The extraordinary revelations come just a day after the Mail told how one of Britain’s flagship £3.5billion aircraft carriers had broken down again and was forced into port in Norway for repairs,” the report said.

Lord West, a former First Sea Lord and Labour security minister, said the attack submarine situation was alarming.

Lord West said it was “unacceptable” and “very worrying” that the Astute submarines were out of action.

“The attack submarines are fundamental for looking after our ballistic missile submarines,” he added.

A second X post also circulated the report as the issue drew wider attention.

The Telegraph reported that all five Astute-class hunter-killer boats are waiting for maintenance and repairs, while a sixth submarine that has been commissioned into the fleet is not yet ready to deploy.

“All five of the UK’s Astute-class hunter-killer boats are awaiting maintenance and repairs. A sixth, which was commissioned into the fleet, is not yet ready to deploy,” The Telegraph reported.

The Telegraph said naval commanders warned the situation damages Britain’s credibility at a time when Russia has increased naval activity around British waters by one-third over the past year.

“Naval commanders have said the situation makes the UK look ‘toothless’ in the eyes of Russia, which has ramped up naval activity around British waters by a third in the past year,” the report said.

Cdr. Ryan Ramsey, a former nuclear submarine captain, called the lack of available attack submarines a major warning for the British government and defense industry.

Urging Sir Keir Starmer and “major industry players” to “get a grip,” Ramsey told The Telegraph: “We look toothless. The Russians know we can’t put submarines to sea. None of this makes sense to me. You lose credibility against the Russians if you can’t maintain that deterrence at sea. This problem has been hidden for decades. Everyone knew this was coming, but it got kicked down to the next person in charge.”

The reported maintenance backlog places pressure on Britain’s broader defense posture. The Astute-class submarines are designed to track hostile vessels, defend critical undersea infrastructure and help secure the Vanguard submarines that carry the U.K.’s nuclear weapons.

The reports have added to scrutiny of the Royal Navy’s readiness after repeated problems involving major platforms, including submarines and aircraft carriers. With the attack submarine fleet reportedly unable to deploy, former commanders and military figures are warning that Britain’s ability to project strength and protect key assets is being called into question.
