Trident nuclear submarine concludes record underwater deployment

By · Via The Guardian Politics · Published by Everything Blog

In short

The British submarine HMS Vengeance has completed a record 217-day mission, far exceeding the three-month deployments originally planned when the class was designed in the 1990s. Crews of about 140 sailors are enduring prolonged isolation under strict radio silence without external resupply to cover for severe servicing delays. Meanwhile, the first replacement vessel, HMS Dreadnought, will not enter service until approximately 2032. To address infrastructure backlogs blamed on past spending cuts, the Labour government recently unveiled a £26 billion, 10-year investment plan for key naval bases.

A Trident nuclear submarine has concluded a record seven-month deployment, returning to the Faslane naval base in Scotland, where its crew are expected to be greeted by senior members of the government .

HMS Vengeance began its patrol on 12 April and spent 217 days submerged before returning on Sunday, leaving the country when Keir Starmer was in Downing Street and Manchester United were third in the Premier League.

Its tour underwater surpasses the old 205-day record, set by the previous crew, raising questions about the strains placed on sailors and the reliability of ageing submarines sent on the extended missions.

“Patrols are getting longer and longer,” said David Cullen, a nuclear expert with the Basic thinktank. “The fleet was designed around three-month tours, and that was considered to be a long time to be stuck underwater in a metal box with no contact with the outside world.”

The increase in the time spent at sea reflects the slow pace of submarine maintenance, prompting Labour to blame spending cuts implemented by the Conservatives, though naval chiefs insist there is a…
