So now that you're all done with the technical part, how about some strategy?

AIP subs deny you access to a coastal sea zone, what are your options?

1. Find another way in, maybe use giant flying wings/zeppelins to land your troops (actually I just want the tech developed for civvie use).
2. Do the Pearl Harbor and start the war with the bombing of the subs while they're in port/vulnerable/pin-pointed.
3. Get your own AIP hunter subs in there somehow, that's gonna be a long journey.
4. Build a giant airborne fishing net connected to an EMP generator (3 giant flying wings/zeppelins) and sweep the sea zone frying any subs that come in contact with the net.
5. Call the Ghostbusters.
6. Call in the Thunderbirds.
7. Use decoys: send in a large remote-controlled fleet of cheap WW2 Liberty Ships equipped with massive decoying devices to completely blind the subs, the rest of your force stay sharp to shut down the decoys at any moment and detect the subs that started moving.
8. Send in Kapitain in the Jahre Viking, with a keel that deep chances are he'll ram the subs.

Any other simple solutions? #7 seems pretty reasonable, if you can't hear you can't aim and if you can't aim you can't shoot and if you do shoot you can only hit a worthless decoy.
