Of special note is the main armament of the Washington/ North Carolina. They were designed to carry 12 - 14" (50 caliber) rifles in three quadruple turrets. This was a new, unproven design and the armament was changed to the 9 - 16" (45 caliber) rifles in three triple turrets. The change was made when the Japanese failed to sign the 1936 London Naval Treaty. The main armament change was made in November 1937 after the keel of the North Carolina had been laid. The United States had expected the Japanese not to ratify the treaty so the quadruple 14" and the triple 16" turrets had been deliberately designed to be almost the same size and weight. Only minor alterations to barbette structures and turret fittings were required deliberate design compromises had been accepted and the barbette diameters and foundations were compatible for either gun design. The Navy did good on this one as future events in WW2 would show.
