No just for Singapore but for the rest of Allied colonies in WESTPAC such as the DEI and the Philippines, you need airpower and not just more planes and better planes but better developed airfields with shelters and revetments and taxiways and established maintenance facilities and robust AAA and good early warning.
There is a good book called "Fortnight of Infamy" that details the first two weeks of the air war in WESTPAC and it does a pretty good job of showing just how unprepared for war the Allied air forces were because the infrastructure to support modern air forces had not been developed yet. The Americans could have had P-51 Mustangs, the British could have had Spitfires of the latest variant, and the Dutch could have had F4U Corsairs and it would not have made that much of difference because we didn't have the infrastructure developed to support those forces.
P-40s(with the Fighting Tigers in China and in Burma) could fight toe to toe with the best Japanese aircraft. Stupidly Japan didn't believe in putting armor on their fighter planes.
