I built an Acc and 2 trns G1. I did almost exactly this strategy mentioned, and put my conglomerated navy without subs of course off of west germany. Feigning the Sealion.
This was awesome, of course the UK fell back, and huddled in england. I then split my navy - one small arm taking Gibraltar, the other cruiser,remaining sub/subs, and planes, and smashed the last bit of UK fleet. My build - placed in West Germany -was also 4 subs and some planes.
This put me in an excellent position. By the end of G2 I had a battleship and fully loaded acc of the coast of Gibraltar - which was mine - with transports - with full loads sitting in GIB and Morocco. 4 Subs off of west germany mixed with air cover, meant britain couldn’t do a damn thing to stop me - they saved money for a bigger navy and built a few more ground units. Axis ground elements in Europe spent time cleaning up the pro-allied neutrals and so on. and getting into position against Russia.
G3 I toyed HARD with invading Canada, it really almost made sense to, but I knew it wouldn’t make me money and I would lose a trn and units to the US eventually. so… Combat ships and 1 trn Navy went back up to W.G. coast, 1 trn went into Med to get units closer to egy (then later took F. Mdgscr, and other african coast.) another trn, went south, along africa’s west coast and took territory, - God I WISHED Argentina was a Pro Axis Neutral!!!
All in all, I would do this again and again, it was fun, it worked well, there were tons of options, and it caused my opponent all kinds of strife and tribulation. ALSO, if your opponent is going heavy pacific in GLOBAL, this is a SERIOUS PLOY for US EAST COAST Invasion. Even with my opponent going KGF, he had built excess transports, and his navy was only equal to mine, as some elements had gone to Canada. This was a REAL sleeper, and if he had payed a little less attention, or didn’t have good buys, G3 or G4 could have been a successful EUS capital crush. Definetely try this out.
The final result of all this action was that I got to make a choice with my navy, either to destroy American fleet, or British fleets as they advanced. I opted to kill the Americans as for me it made more $ sense, I cleaned up and made over 70 IPC’s difference by the time I lost my navy into his, it was an excellent trade.
Note
A weakness I found was that the Russian Navy partivularily by R4 isn’t detroyed and threatens Berlin, be careful. My russian opponent even built an ACC when he saw my navy go south, it was a btch dealing with it later.
