The future Royal Navy submarine HMS Anson was recently floated out at BAE Systems' Barrow-in-Furness site in Cumbria.
The submarine is currently undergoing the next phase of its test and commissioning programme. It is scheduled to leave Barrow next year for sea trials with the Royal Navy.
The future Anson is the fifth Astute-class nuclear-powered submarine to be built by BAE Systems. Once completed, it will have a length of 97 metres, a hull diameter of 11.3 metres, a submerged displacement of over 7,400 tonnes, and a maximum speed of 30 knots.
Armament will include Spearfish torpedoes and Tomahawk cruise missiles.
