Nuclear-powered attack submarine is launched

The sixth of seven Royal Navy attack nuclear-powered submarines has been launched.

The Astute-class HMS Agamemnon, named after the ancient Greek king, was hoisted into the water by BAE Systems in Barrow-in Furness.

Astute class are the most powerful attack submarines ever operated by the Royal Navy.

Agamemnon Commanding Officer, Cdr David Crosby, said there was "plenty to do until we get to exit Agamemnon from Barrow, but the entire workforce should be full of pride for what they have achieved with this build so far".

Agamemnon, a 318ft-long (97m) vessel, will now begin the next phase of its test and commissioning programme, BAE Systems said.

The first five submarines, HMS Astute, HMS Ambush, HMS Artful, HMS Audacious and HMS Anson, have been handed over to the Royal Navy.

The final boat in the fleet, Agincourt, is being built.

BAE Systems said the vessels' nuclear technology meant the submarines never need to be refuelled and, by manufacturing their own oxygen and drinking water for crews, the boats were able to circumnavigate the globe without surfacing.

BAE Systems Submarines' managing director, Steve Timms, said submarines were a "vital component of the UK's defence capabilities".

"The design and build of a nuclear-powered submarine is incredibly complex and a truly national endeavour and I pay tribute to the thousands of highly-skilled people who have helped get Agamemnon to this stage."
