Well, what can England possibly have in SZ 3 on UK 1 that Germany would attack?
2 Transports, 2 Fighters, Battleship, Carrier, Destroyer, Russian Submarine, right?
Best possible the Germans can expect to have, reasonably, on G2 to attack that with is 2 Submarines, Destroyer, Transport, 5 Fighters, Bomber.
You should be able to sink the entire enemy fleet with reasonable fighter losses.

Attacker: 3 Fighters, Bomber - 13 Punch - 2 Hits

Germany wins with 2 Fighters, Bomber and England has no fleet now. That means they need to build air force AND capitol ships to defend their transports before they can build transports. (Or at least it locks America’s capitols in the North Atlantic protecting British transports.)
As for Germany’s losses? That’s easily recovered if you want to build fighters instead of tanks, tanks being an item I don’t normally use as Germany too often anyway.
