HMS Triumph (S93)

HMS Triumph was a Trafalgar-classnuclear submarine of the Royal Navy and was the seventh and final boat of her class. She was the nineteenth nuclear-powered hunter-killer submarine built for the Royal Navy. Triumph was the tenth vessel, and the second submarine, to bear the name. The first HMS Triumph was a 68-gun galleon built in 1561.

Triumph was laid down in 1987 by Vickers Shipbuilding and Engineering. The boat was launched in February 1991 by Mrs. Ann Hamilton, wife of the then Armed Forces Minister Archie Hamilton. She was commissioned in October that same year.

After returning to her base at Devonport for the final time in late 2024, Triumph was decommissioned in July 2025, being the last boat of her class in service.
