I wouldn't look for subs in the near future. A Sub would only exist to sink shipping and without individually controlled ships, and an easier ship control interface, there wouldn't be much use for them.
As it is now, you control a Task Force. One CV, one Cruiser/Battleship and 4 Destroyers. But any course you program in, the entire fleet follows it. Imagine plotting the course of a Bomber formation and have to try to defend against fighters the same way you would have to if they were a Task Force.
Subs would be nice, however I think you can hold off till AHIII or so.
