Good thread , this ! I think that every airforce had trouble using conventional bombers to hit Naval vessels until the advent of dive bombers in the 1930's . Even the Skua was a better bet than most normal bombers & the Dauntless was in a class of its own during the Pacific campaign . I don't think you can really count the Kamikases as they were really just piloted cruise missiles & probably would n't have been a particularly popular mode of combat with allied fliers !
