A whole fleet of submarines that protect the United Kingdom from nuclear threats has been removed from service after being deemed unfit for use. The development comes as the head of the UK’s military warned that current threats, particularly from Russian President Vladimir Putin, exceed those of the Cold War era.
Astute-Class Submarines Docked
According to a report by the Mail on Sunday, all five Astute-class submarines—which are responsible for safeguarding the submarines carrying Trident nuclear missiles—have been docked and are undergoing repair work. Military experts fear this leaves the UK’s undersea internet and power cables more susceptible to Russian hybrid warfare attacks.
A naval source told the newspaper that a lack of investment over decades in backup infrastructure to maintain the submarines safely contributed to the current situation.
Ministry of Defence Response
A Ministry of Defence spokesperson stated: ‘Strengthening and sustaining our submarine capability is a top priority, and we are taking decisive action to ensure its long-term resilience. The Strategic Defence Review has underscored the critical importance of sustained and targeted investment across the Defence Nuclear Enterprise, and we are unwavering in our efforts to deliver the resources, infrastructure, and support necessary to meet current and future operational demands.’
The spokesperson added: ‘We do not routinely comment about specific submarine operations and availability, but British waters are always protected with a range of assets including warships, patrol aircraft and submarines.’
The MoD has faced recent criticism over security breaches and mechanical failures. On Saturday, a technical issue was detected on the UK’s largest warship while docked in Norway. Earlier in the week, it was reported that more than 40 suspected security breaches are reported to the MoD daily, including thousands of reports of lost hardware such as phones and laptops, as well as assets considered attractive to terrorists.
Former Minister’s Warning
Quoted by the Mail, a former Labour security minister commented: ‘The attack submarines are fundamental for looking after our ballistic missile submarines. The fact that there has not been money invested in dry docks, in the maintenance facilities, in the men required to maintain and repair the submarines, in the spare parts for those submarines is why we have got to this position. It is just unacceptable and puts us in a very difficult position. If we haven’t even got an attack submarine available for use, then things are looking pretty bad.’
Chief of Defence Staff’s Assessment
Chief of Defence Staff Sir Richard Knighton told BBC Radio 4’s Today programme on Friday that the UK is in the ‘most dangerous period’ due to Russia’s use of cyber attacks, technology smuggling, reckless sabotage, and assassination attempts to test and challenge defences. He said: ‘In my 35-year career, this is the most dangerous period that I have known, and as a consequence, it is important that we enhance the capability and the readiness of our armed forces alongside our allies to deter our adversaries from doing something daft.’
The situation underscores the critical need for sustained investment in the UK’s naval infrastructure to maintain national security amid rising global tensions.
