HMS Anson, the fifth of seven Astute class attack submarines being built for the Royal Navy, has been launched at Barrow-in-Furness, Cumbria.

The 7,400-tonne nuclear-powered submarine, officially named at a ceremony in December, emerged from the Devonshire Dock Hall and entered the water for the first time earlier today (April 20). The launch was a special moment for the Barrow shipyard, which is celebrating its 150th year and a long and proud relationship with the Royal Navy.

Anson will now begin the next phase of its test and commissioning programme, before leaving Barrow for sea trials with the Royal Navy next year.  

“The launch marks an important milestone in the Astute program and seeing Anson enter the water at such an advanced state is a tangible demonstration of everyone’s hard work over the years. Designing and building nuclear-powered submarines is a national endeavor and days like this bring a huge sense of pride for our workforce, our partners in the submarine enterprise, and our UK supply chain, not to mention our communities. We now look forward to a successful test and commissioning phase and working alongside Anson’s crew to prepare the submarine for operations with the Royal Navy.” said Steve Timms, Managing Director BAE Systems Submarines.
