After studying the map and the initial setup, I think that although a G1 air raid on UK will be feasible, it will not be compatible with a G2 Sea Lion (and possibly a G3 Sea Lion as well, though that is harder to plot out).
Germany has 6 fighters/TACs and a bomber that can reach UK, and one fighter that can’t (Norway). If you attack with 5 Fighters/TACs and a bomber, you expect 1 AA hit, and the battle will then be two threes and three fours against two twos and three fours. Basically even, and expecting a mutual annihilation. (Also, two of the attacking fours get degrated to threes when their matching fighter gets destroyed, so effectively they’re fours that have to get hit first), so that battle really is almost dead even. Therefore, you’ll want to attack with all seven aircraft that can attack, getting reduced to 6 and winning while losing about 2/3s of your air force. That leaves 5 subs, one fighter, and the Baltic Fleet to destroy as many UK ships as possible. The Baltic fleet can destroy the Cruisers in SZ112, but may lose a cruiser to do so (~50%). Two subs can destroy the destroyer and transport. Three subs and a plane can destroy one battleship+escort, but the other Battleship and escort will survive. They plus the carrier, TAC, and destroyer in Gibraltar can attack SZ112, which means that you can’t just load it up with transports, and if you build enough to defend that SZ (An aircraft carrier, landing two of your surviving planes is your best bet, which would let you buy two more transports), you probably don’t have enough transports to take UK on G2 if they build all infantry.
G3 might be doable, but the permutations get out of control.
I think, if you’re going to do Sea Lion, you’ll need to focus your air force on destroying UK’s navy, rather than strafing their air force.
I feel a little bit better now.
