How would better Imperial Japanese Army and Navy cooperation affect Japanese war plans?
Short answerStandardized equipment, fewer parallel production lines, and better information sharing could increase what Japan's industry produced and improve planning.
NotesDuplication was a major cost of rivalry between the Imperial Japanese Army and Navy. Standardizing guns, aircraft, and production lines would concentrate scarce industrial capacity instead of sustaining parallel systems. Shared, accurate information would also improve planning. Cooperation alone would still leave Japan's wider strategic problems unresolved.
