Sixth Astute Class submarine launched in Cumbria
The Royal Navy’s penultimate Astute Class attack submarine attack submarine has been launched at BAE Systems in Barrow-in-Furness, Cumbria.

HMS Agamemnon is the sixth of seven Astute Class submarines, all of which have been designed and built at BAE’s Barrow shipyard, which was founded in 1871 and launched its first submarine in 1886.
The 7,400 tonnes nuclear-powered boat rolled out of the Devonshire Dock Hall and entered the water for the first time on October 3, 2024.
Steve Timms, managing director, BAE Systems Submarines, said the launch is ‘a hugely significant milestone’.
“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 HMS Agamemnon to this stage,” Timms said in a statement. "Submarines are a vital component of the UK's defence capabilities and we must now work collectively to ensure HMS Agamemnon is ready to join her sister submarines in service with the Royal Navy."
HMS Agamemnon will now begin the next phase of its test and commissioning programme, before leaving Barrow for sea trials with the Royal Navy.
