The shipyard counterfactual then moves into the operational campaign. Additional carriers might have brought more aircraft to the Battle of the Coral Sea and the Battle of Midway, where early losses sharply limited Japan's ability to consolidate its gains. Even so, Japan could not ultimately defeat the combined industrial power of the United States, Britain, and the British Empire. The plausible strategic aim was to win overwhelming early victories, fortify the captured perimeter, and erode the Allies' willingness to continue the war. In that logic, shipyard capacity and extra carriers mattered because they increased the resources available during the short opening window. The conclusion returns to Fushimi's preference for impressive ships over the practical infrastructure needed to build and sustain a larger force.

Extra carriers at Coral Sea and Midway
The carrier counterfactual matters because more early air power might have changed Japan's opening battles and bought time, not because it could erase Allied industrial superiority.
