I did the interview with HiTech where he broke the news on Submarines. It was at the '01 Con. If I understood his concept correctly, there will likely be wolfpacks that will operate like fleets, i.e. you set waypoints for them. When they come within range of an enemy fleet or convoy, you'ld spawn a uboat and make your attack. The idea was to allow players to do the fun part (attack and evade) while avoiding the boredom that constituted 99.999% of submarine duty. He mentioned that there would be a dedicated ASW platform, some type of player-commanded sub-chaser, as well as ASW weapons for aircraft. Personally, I hope you'll be able to spawn from ports as well. Imagine how much more perilous it will be to CV camp near an enemy port in that case.
