How would a squadron of the triple-4.7-inch cruisers fare in the Guadalcanal battles?
Short answerThey could put a large volume of shells onto destroyers and light cruisers, but their shorter gun range would make Japanese heavy cruisers a serious problem.
NotesProperly designed triple 4.7-inch turrets could give these hypothetical cruisers a very high rate of fire. Japanese destroyers would be particularly vulnerable to the volume of shells, and light cruisers would also face heavy fire. Their guns would have less range than six-inch or eight-inch cruiser weapons. Japanese heavy cruisers would therefore be a serious problem for the squadron.
