Would navies field cruisers with guns larger than eight inches by 1942?
Short answerProbably, given the Alaska class, British interest in 9.2-inch guns, and the German panzerschiffe.
NotesThe Alaska class supplies the 12-inch example. British interest in 9.2-inch guns offers another route beyond the conventional eight-inch heavy cruiser. The answer also names the German panzerschiffe. These examples support continued interest in larger cruiser armament, without identifying a specific P-class programme as the German example.
