What if Japan used Yamato and Nagato at Guadalcanal instead of Hiei and Kirishima?
Short answerThe battle becomes larger and costlier, but logistics and the range of the night engagement mean an American victory remains possible.
NotesThe heavier Japanese battleships could inflict substantially more American casualties if Japan could supply and deploy them. Victory would still not be automatic: the same operational course could produce a narrow American success, particularly depending on how close the forces meet in darkness.
