Could Canberra-class LHDs replace Bay-class ships and be crewed by the Royal Fleet Auxiliary in peacetime?
Short answerNo. Canberra-class ships are full warships and closer replacements for Albion and Bulwark, while the RFA-crewed Bay class should remain as complementary amphibious lift.
NotesA Canberra-class LHD would be more than a larger Bay-class auxiliary. The Canberra design is a full warship requiring a naval crew and is closer to a replacement for Albion and Bulwark. An RFA-crewed Bay-class landing ship provides a different kind of capacity alongside combatants. The later answer argues that Britain should have retained at least four Bay-class ships instead of reducing the force after transferring one to Australia.
