I agree with Jen, the dilemma for the US is where to concentrate on the first 3 turns. Having experimented with a J2 or J3 attack on the US fleet in the pacific, I am now reluctant to leave my US fleet anywhere near the possibility of attack on J2 or J3. I move it to SZ64 (Panama) asap now and defend the west coast with ground/air units. That way I save the pacific fleet and can build a reasonable task force in the atlantic to cause some havoc against the Germans/Italians. Also if the jap fleet has gone hunting the US fleet, then I declare war on the japs with the UK/Anzacs and use my transports to take as many islands as possible which is great nuisance value (as well as generating more income for the allies) and turns the attention of the japs back to the DEI/Australia etc. I use the two turns it takes the jap fleet to get back into action (against the UK and Anzacs) to build some nice BB’s and CV’s for the yanks, join up with the intact pacific fleet and then off I go hunting.
Its about buying time as the allies…do as much as you can to avoid engaging the japanese fleet too early, it is too strong.
So to summarise, retreat the pacific fleet to safety, build in the atlantic the first 2 turns (2CV’s, a BB, 4 destroyers and 3 or 4 transports will do the job) and then concentrate on building up the pacific fleet thereafter.
I target Norway (vide Gibraltar) as the yanks when possible in order to build a US factory on Germanys doorstep. The atlantic build also gives the German player something to think about when considering sealion.
Just my experiences.
