@LT04:
It wasn’t so much getting there that was an issue I gained ground but then he would replace his subs from stock so if I needed to get a second wave I had to have the navy escort the transports back.
Also if the FTR’s didn’t hit the sub he would have them submerge.
I’m not saying this is the best strategy it was just a simple and fairly inexpensive (as far a navy’s go) way to buy time before you have enemy troops setting up beach heads on your door step.
If subs submerge, you can still move your fleet through or into those zones as if there were no units, so if it’s just subs and you have enough of a fleet to withstand an attack from them, you can plow through at full speed as if they weren’t there by just sending one plane to each territory - they’ll either sink or submerge and you can move your fleet 2 spaces every time. (However you may not want to leave those subs hanging around your supply lines to your main fleet, but that’s another story.)
