Did you have that backwards? Did you mean to recommend having a Destroyer escort all warships? Certainly you need to have something escort transports of enemy air or subs will pick them off. I really think folks will come to want more subs. In a sea battle, subs are the best cannon fodder, especially in the attack. But I digress . . . Send Subs to bolster the Aussies by sending them to New Zealand first and then to Aussie coast. This could help amplify protection of Austrailia by delaying any invasion. I bolster most strategic places with lots of infantry since it is very hard for the Japanese to build a large number of transports to support a large amphib landing. When I have a fleet where there is both naval and airbases, I send the planes to land on the island. This way, if an enemy attack comes, I can decide how many planes to scramble, and what types to use. This also allows me to use one hit on a carrier without losing the planes. I am also looking at invading Alaska as the Japanese, but I haven’t done it yet.
