The nuclear powered submarine HMS Tireless has returned to Devonport at the end of her last deployment. The 30 year old boat has been helping in the search for the missing Malaysian airliner off Australia.

Most of her life has been spent as a hunter-killer submarine on top secret missions beneath the Atlantic Ocean, but three years ago she completed the longest deployment ever by a Royal Navy submarine on a ten month world tour.
