@crockett36 the US will always be able to out navy Japan if it spends more than 85%-90% of its IPCs in the pacific. If the US goes 100% in the pacific with a balanced naval build (multiples of 1 Carrier, 1-2 Subs, 1-2 Destroyers, 2 Fighters/Tac Bombers) you will eventually defeat the Japanese if the Indians don’t die early.
Additionally, I’ve been experimenting with using the Australians. If you use your Australian income to purchase carriers, and fighters for those carriers, it allows the Americans to buy a more submarine-heavy fleet. The sub-heavy fleet ordinarily would not be able to defend against the Japanese navy, but with the ANZAC reinforcements, it can get close without worrying about defense.
