Midway with Shokaku and Zuikaku would be far less secure

How might Midway have changed if Shokaku and Zuikaku had joined the Japanese striking force?

Two additional fleet carriers would add reconnaissance, strike, and fighter capacity, making American carrier losses more likely even if Japan still lost several carriers.

The counterfactual assumes Shokaku and Zuikaku arrive with full air groups, giving Japan six fleet carriers against three American carriers. This does not guarantee a Japanese victory. Two more air groups would add reconnaissance, strike, and defensive air capacity. Japan might still lose four carriers, but the United States could lose Enterprise, Hornet, or all three carriers in the exchange. The counterfactual demonstrates how carrier numbers affect the many simultaneous variables of scouting, attacks, and air defence.
