If ABDA Command had Dutch and Australian light carriers, would that change the East Indies campaign?
Short answerYes: independent reconnaissance and air strikes could alter cruiser battles and make Japanese torpedo attacks more hazardous, but both sides would adapt.
NotesA pair of roughly 25-knot light carriers could give an ABDA formation its own reconnaissance and strike aircraft while operating around two capital ships. Japanese torpedo bombers would be working near the edge of their range, so defending fighters could impose losses and disrupt attacks. The carriers would also change how Allied cruisers find and threaten an opponent. No fixed result follows because Japanese plans and tactics would adapt to the additional Allied air power.
