A Japanese partnership offers two routes to a conventional successor: buy an established Soryu-derived design or join the proposed 3,000-ton Japanese programme. British Astute-style sensors could form part of the joint design. Canada might join such a procurement effort, and Australia might also reconsider if its contemporary French programme continued to struggle. Two boats based in the Falklands would add South Atlantic awareness and deterrence, leaving four available from Britain.
