HMS Tireless

HMS Tireless at the North Pole in 2004.

The Trafalgar-class is a class of nuclear-powered submarines in service with the major members of the British Commonwealth. They are a direct follow-up to the Swiftsure-class and were, until the introduction of the Astute-class, the Royal Navy's most advanced submarines.

With thirty-four boats in commission, they form the core of the nuclear powered hunter-killer submarine forces of the British, Canadian and Australian navies. Most submarines in the class have been fitted with the ASDIC 2076 system, which the Royal Navy describes as the most advanced ASDIC in service with any navy in the world.
