The steelwork structure for the command deck module of the fifth Astute class submarine, to be called HMS Anson, has been delivered to BAE Systems' Devonshire Dock Hall build facility.
The 80 tonne module will house the accommodation areas for the Royal Navy crew, including the commanding officer’s cabin, mess facilities, galley, laundry and ward room, as well as the main control room.
The nuclear submarine was constructed in the shipyard’s main steelwork and fabrication facility, before being moved to to the build hall. It will now undergo shot blast and painting.
HMS Anson is expected to enter Royal Navy service in 2020, following on from HMS Astute, Ambush, Artful and Audacious.
