Could King George V have used 4.5-inch guns so scarce 5.25-inch mounts went to the Dido class?
Short answerYes. The change could have freed mounts for Dido and possibly accelerated battleship construction.
NotesThe proposed reallocation was sensible. Substituting 4.5-inch guns on the King George V class would make more 5.25-inch weapons available for Dido-class cruisers. It might also have reduced a production bottleneck and sped completion of the battleships themselves.
