I welcome the hon. Gentleman’s interest in this area. There is currently one decommissioned submarine undergoing dismantling at Rosyth Dockyard (HMS Swiftsure). A further 22 decommissioned submarines are awaiting disposal: six are at Rosyth Dockyard, all defueled, and 16 at Devonport Dockyard, of which four are defueled and 12 are awaiting defueling.
