@the-spaceman Seems like a good start. A few thoughts to throw into the mix:
I would say UK’s naval priorities should be first the Baltic fleet, then any stray transports, then any stray subs. The subs don’t do any convoy damage or anything like that, so they’re really just targets of opportunity; it’s not like you can safely leave British transports unattended anyway because of the German bomber, so the subs aren’t doing that much more harm. The Baltic fleet is top priority because it allows Germans to cheaply conquer Norway/Finland/Karelia, and because it’s too expensive for Germany to sanely replace.
The Australian transport can flee across Argentina to the Atlantic, but I would leave the destroyer behind to block a J2 attack on Australia – I think it does more good slowing down Japan and keeping some of the UK income than it does to get a destroyer added to your Atlantic fleet, like, 3 turns later. For similar reasons, I usually won’t move the starting US Pacific fleet to the Atlantic. If the Allies took unusually heavy naval losses, then maybe it’s worthwhile, but the Pacific fleet is earning you nothing the whole time it’s in transit through the Panama Canal. Having a few starting boats in the Pacific – even just CV, ftr, DD, tran – means that if you ever do need to upgrade the Pacific fleet into a formidable force because Japan is grabbing Alaska and Hawaii or whatever, then you can do so with one turn of purchases. If you can’t quickly reinforce the US Pacific fleet to the point where it can drive away the Japanese navy, then you might be forced to buy 10 infantry for the Western US instead or something similarly expensive and wasteful.
It doesn’t always make sense to build a huge Atlantic fleet at all as the Allies – sometimes you can sink the Italian fleet using primarily air power and subs, and/or build a pair of factories in Egypt, South Africa, India, or Australia. Some games you won’t have enough good safe factory sites, and some games you’ll need a big fleet because, e.g., Germany is heavy on air power (so you need protection for your transports) but short on infantry (so invading France is really attractive). On the other hand, if Germany trades its entire air force to wipe out your boats on G1, builds a factory in France on G1, and then drops 6 infantry there on G2, maybe just let the Atlantic navy go for several turns and rely on factories instead, or have the British build factories and let the Americans reinforce with a fleet into Morocco after they build up.
