Perhaps I am missing something here.
In the battle of Coral Sea and again at Midway, the enemies engaged each other solely by aircraft alone and the opposing fleets suffered damage and destruction solely by aircraft alone.
And it was the action of these aircraft that altered the intentions of the fleets - in the case of Coral Sea, the planned invasion of Port Moresby was abandoned and in the case of Midway, the invasion of Midway island was abandoned.
There were no engagements by surface ships or actions by submarines that influenced the course of either battle. The order to abandon the Port Moresby invasion was mainly due to the fact that the Japanese suspected there were more Allied carriers in the area...in otherwords, for the fear of more air attacks.
Except for the fact that, except for land-based aircraft at Midway itself, all those air sorties were flown off ships. Ergo to say it was "only aircraft" is stretching things a little. It took a lot of naval resources, not just the carriers themselves, to get both sets of forces ready for action around Midway.
Strategic change occurs when your overall objectives are forced to change. That didn't happen due to fighters at the BoB, and it didn't happen solely because of coral sea or midway. They were big operational successes, but they were not overwhelming strategic victories 9as is so often touted for them0 because they did not lead to any change in Japanese objectives at the time, or allied objectives either 9well maybe watchtower was made possible I guess)
Again, 'fraid I disagree. The extent to which an action is or is not strategic is largely dependent on each side's primary strategic centre of gravity. It is entirely possible for a battle to have major strategic consequences even if an adversary's strategy doesn't change.
Take the Battle of Britain as an example. Until that time Hitler had the luxury of, for the most part, embarking on a sequential series of campaigns with a common objective. Everything was moving in one direction and he was never forced to fight a true 2-front effort. After the BoB, the entire strategic calculus had changed. Hitler had to face the prospect of a 2-front war which any good student of military history will tell you is a recipe for disaster. Fortunately for the Allies, Hitler's megalomania refused to concede that he could possibly lose and so he pressed ahead. His strategic objective remained unchanged but the context surrounding that strategy had shifted seismically against him...it's just that he refused to respond to that change. The ultimate result was disaster for his aspirations of global dominion.
Bottom line...you don't have to force a change of adversary objective to result in a strategic impact. If the enemy is too stupid to realize that the situation has changed, they may well press ahead with original plans, to their own detriment.
