Motto:

HMS Tireless (S88), a Trafalgar-class submarine, is the second submarine of the Royal Navy to bear this name. She was launched in March 1984 sponsored by Mrs Sue Squires, wife of Admiral 'Tubby' Squires, and commissioned in October 1985.

Over the next six years, Tireless completed numerous exercises and visits around the world, including a trip to the Arctic in 1991. Five years after that, she entered refit in early 1996, and returned to sea in 1999.

On 12 May 2000 Tireless suffered a loss of coolant accident, and put into the port of Gibraltar for what was hoped would be quick repairs to a minor crack in a coolant pipe. However, the damage transpired to be more extensive that was first hoped, and the boat remained at Gibraltar, creating diplomatic tensions between Spain and Britain, until she left on 2 May 2001, nearly a year later. During that year, all Trafalgar-class submarines were inspected for similar problems.

On 19 April 2004, Tireless and USS Hampton (SSN-767) rendezvoused under the Arctic ice and surfaced together at the North Pole.

Tireless again angered Spain in 2004 when the boat put into Gibraltar from 9 July to 15 July for what were explained as "technical reasons." Britain assured Spain that the port call was unrelated to the British celebrations, on 21 July, of the 300th anniversary of the capture of Gibraltar from Spain.
