With the utmost respect, I don’t understand how your points relate to not lowering the costs of transports, carriers, or aircraft.
Assuming you support the idea of lowering the cost to build a navy in general to encourage building them without the need for silly national objectives; if you only lower the costs of subs, destroyers, cruisers, and battleships, then the cost of the aircraft carrier and aircraft combination is now out of whack causing them to lose the dominance they are suppose to have.
Making transports cost $7 and having no defensive capabilities, made the transportation of materials even more expensive, which had no effect in the Atlantic because the US HAS to go there.
But in the Pacific, raising the cost to transport men and material and MORE SPECIFICALLY, the transports losing there defensive capabilities, made building a Navy to defend the transports, even more expensive, making it even more inefficient for the US to engage the Japanese.
So then that forced the stupid Japan 6 VC rule, to force the US to spend its resources inefficiently.
I agree with you that the old idea of building only a few ships and a boatload of transports was not fun, EVEN THOUGH, technically, in the old transport rule, a transport represented the transport ships, the landing craft, and escorts.
What’s the difference, spend 24 IPC’s for 3 transports that defend at 1 with the old rule, or spend 24 IPC’s for 2 destroyers that defend at 2 with the same 3 transports with the same rule. This would assume two destroyers would cost 6 IPC’s and transports would cost $4 IPC’s.
