Navy Lookout – A submarine returned home to the Clyde today following the longest ever patrol by a British nuclear deterrent-carrying boat. This submarine left Faslane in late August and has been away for 204 days. This breaks the record achieved in 2023, an extraordinarily long time for the crew to spend underwater. This submarine was relieved in the last few days by another boat that sailed last week, following significant delays in getting it ready for sea. The length of patrols has been rising sharply over the last few years. The last eight deterrent patrols have all exceeded five months in duration. Today’s homecoming is another epic achievement, even if spending almost half a year underwater is becoming ‘normal’.
