What changes if a B-17 hit by flak crashes into a Japanese carrier at Midway?
Short answerThe carrier could be lost, and an early Japanese withdrawal in response might prevent the historical carrier battle from unfolding at all.
NotesJapanese carriers emphasized air-group capacity more than the ability to absorb an impact of this scale, leaving any of the Midway force in serious danger from a crashing heavy bomber. The older or lighter carriers were especially vulnerable, but the operational decision that follows matters more. If the loss warns the Japanese that strong American forces are present and prompts withdrawal, the carrier fleet may survive for a different battle and the familiar Midway sequence never occurs.
