Do these AI Uboats have to 'exist'?
The imagination would be good enough for me.
Let the AI radio a convoy and when I'm close and in position I send my ok and the wolfpack leader orders to attack.
Or I radio the convoy position and have to shadow it. After a while I get response of two comrades at the other side of the convoy to be in position and I start the attack.
The convoy has some random chosen ships with 'torpedo damage function' - they'll be hit by 'magnetic eels of the imaginary comrades'.
Two DDs leave the screen and start to DC an area somewhere on the other side of the convoy...
I even scripted a single player mission like that (U42 Wolfpack) back in 2005.
