Would a Canberra-class design meet the proposed Royal Navy LHD requirement?
Short answerNo; a Trieste-like ship, probably somewhat larger and properly equipped for F-35Bs, would be a better basis.
NotesThe Canberra class is rejected as a direct model because its aviation facilities are not arranged for sustained F-35B operations. The Italian Trieste is offered as a more suitable starting point, though the British ship might need to be slightly larger. That choice aligns the amphibious hull with the earlier proposal for ships able to supplement the strike carriers in an emergency. A ski jump alone does not provide the full aviation facilities needed to operate those aircraft.
