The Royal Navy's newest nuclear submarine has been rolled out of its dockyard in west Cumbria.

The 7,400-tonne Audacious, which is capable of firing Tomahawk missiles, was built at BAE System's site in Barrow at a cost of about £1.4bn.

The 320ft (97m) long Astute-class vessel will now undergo preliminary tests ahead of sea trials next year.

Three other Astute-class submarines are at different stages of construction at the Barrow yard.

The submarine, which will be one of a fleet of seven, is also armed with Spearfish torpedoes, fitted with the latest sonar capability and powered by a nuclear reactor.

The Astute-class are the largest and most advanced attack submarines operated by the Royal Navy.

A Royal Navy spokesman said: "Ahead of Audacious, HMS Astute, Ambush and Artful are already contributing to operations and are well placed to protect both the Queen Elizabeth-class aircraft carriers and the Continuous At Sea Deterrent.

"The nuclear submarine remains the hallmark of a first-rate maritime power. Audacious, and the men and women of the Royal Navy submarine service, will give the UK a decisive advantage for decades to come."
