HMS Trenchant
HMS Trenchant, a powerful hunter-killer submarine with an illustrious ancestor. HMS Trenchant, the fifth of the seven Trafalgar-class submarines built at Barrow, was launched on 3 November 1986 in front of a special guest – war hero Vice Admiral Sir Arthur Hezlet, who commanded the wartime Trenchant with notable success. The admiral would have been struck by the huge advances made between his boat and the current Trenchant, not the least in her propulsion.

All Royal Navy submarines are nuclear-powered, giving them virtually unlimited range and the ability to stay submerged for as long as the crew's food supply holds out.
Although she has been around for more than two decades, Trenchant is an impressively powerful war machine.
She was given a major refit and overhaul in the first half of the last decade, during which time her nuclear reactor was refuelled, at which time she was also fitted with state-of-the-art Sonar 2076, which is being built into the new Astute-class boats which will replace Trenchant and her sisters

Military experience
Irvine Lindsay joined the Royal Navy as a Midshipman in 1983, and has spent the majority of his career at sea in various ships and submarines.
After his initial training in the surface Navy in HM Ships Torquay, Sheraton and Liverpool, he qualified as a Ship’s Diving Officer in 1986. He then served as a junior warfare officer in the Falkland Island Patrol Vessel HMS Sentinel, the destroyer HMS Edinburgh and the offshore fishery protection vessel HMS Guernsey before volunteering for the Submarine Service in 1989.
Qualifying for his submarine ‘Dolphins’ in HMS Spartan in 1990 he served in warfare appointments in HMS Unicorn, HMS Turbulent and HMS Triumph, passing the Submarine Command Course, known as ‘Perisher’, in 1997. He was selected for the 1st Joint Advanced Command and Staff Course, graduating with an MA in Defence Studies from Kings College London, before returning to sea in HMS Trafalgar as Executive Officer.
His first shore appointment in 17 years was to the staff of Commander British Forces Gibraltar as the Maritime Operations Officer. He subsequently served on the staff of Commander-in-Chief Fleet and then for Flag Officer Sea Training running the Submarine Command Team Trainer in Faslane. Following promotion in 2006, he commanded the Trident missile submarine HMS Vanguard and had the unusual distinction of conducting deterrent patrols as captain of both Port and Starboard Crews. On relinquishing command he had the good fortune to serve on the Navy Staff in the British Embassy in Washington DC.
Selected for further sea command after 12 months ashore Irvine is delighted to be back in the best job in the Royal Navy, as Commanding Officer of the nuclear attack submarine HMS Trenchant.
