Britain's latest nuclear submarine arrived in Gibraltar this morning. HMS Audacious, a hunter/killer submarine is paying first visit to The Rock. She is considered to be one of the world's most potent submarines armed with torpedoes and Tomahawk cruise missiles.

HMS Audacious is the fourth Astute-class nuclear-powered fleet submarine and one of the biggest submarines ever built for the Royal Navy. She displaces almost 8,000 tons.
