HMS Tireless

HMS Tireless

HMS Tireless was decommissioned after nearly 30 years of largely secret and silent service at an emotional service in HM Naval Base Devonport on 19 June 2014.

In the past twelve months HMS Tireless has spent just seven weeks in her base port following a deployment to the Mediterranean, a busy displaced maintenance period in Faslane, and a final East of Suez deployment. The submarine becomes the third Trafalgar Class vessel to be decommissioned in Plymouth.

The submarine worked right up to the end and, unusually, was the centre of world events when she helped in the search for the missing Malaysian Airlines flight MH370 with her underwater sonar.
