The last gun action surface took place on Tuesday 3 December 1974. A signal sent by the Captain A.P.Hoddinott was relayed to FOSM, Aussie Navy, Canadian Navy and the Yanks and read "The reek of cordite has passed from the Royal Navy's Submarine Service. Last gun action surface conducted at 031330 zulu. Time to first round,36 seconds. May the art of submarine gunnery rest in peace but never be forgotten." The gun was Auriga's fitted on the Andrew after refit. Hope this clears up a few questions. D.B.F.
