HMS Audacious (S122)

The Royal Navy’s Astute Class nuclear-powered submarines are among the most sophisticated underwater vehicles ever constructed. HMS Audacious, the fourth submarine in the range, was launched in April 2017.

£1.2 billion contract awarded for new attack submarine


HMS Audacious is employed in a variety of important roles. These include covert intelligence gathering and strategic strike using the fearsome Tomahawk Land Attack Missile.

The crew of HMS Audacious also undertake a number of defence engagement, charity and outreach tasks in the community around Barrow-in-Furness, where she was constructed.


HMS Audacious has provision for up to 38 weapons in six 21-inch torpedo tubes. She is capable of firing Tomahawk Block IV land-attack missiles (with a range of 1,000 miles) and heavyweight Spearfish torpedoes, which can attack targets up to 14 miles away (and this range can be increased to 30 miles at low speed).
