I don’t quite follow, are you saying the earlier Brit Carriers included major (12” or better) gun turrets?
The caption says “Churchill on carrier in Newfoundland, 1941.” If the caption refers to the big picture, that’s a battleship he’s walking on, not an aircraft carrier. If it refers to the inset picture of Churchill, FDR, and Stalin, that’s in Yalta, in 1945, not in Newfoundland in 1941.
My comment was a bit of obscure and pedantic humor. The Japanese did build some hybrid battleship/aircraft carriers, but they proved not useful in either role.
