Japan has maintained a steady throughput of ships and is expected to need another destroyer design after its large Aegis system equipped vessels. Italy also appears in the proposed grouping alongside Australia and Britain. France is treated as a possible additional participant because of Horizon ancestry and a similar replacement timeline, with its nuclear-carrier and possible nuclear-escort discussions left as an unresolved difference. Strong air defense is a shared requirement in this comparison. Broader capability also matters: Type 26 and Type 31 illustrate ships with an emphasis on particular roles while retaining flexibility beyond them. Type 26's Royal Navy anti-submarine role is specifically distinguished from being exclusively an anti-submarine ship.
