I'm not so sure about an AI subs not going from surface to submerged. Maybe it is only a US Fleetboat issue.
If you could look into the U-Boat side you will find many Russian Submarines when fired upon with deck guns will submerged to escape. I have seen them do this to me so often that I have stopped firing at them with the deck gun and instead only use torpedoes now.
Another thing I would like to see is TMO, RSRD, and RFB also have playable U-boats for the Pacific. They were there so why not be able to switch sides so instead of coming across an AI U-Boat you could actually be that U-boat passing through the Luzon Straits, hiding in the Bungo for unwary US Naval vessles or taking your chances by slipping into a harbor or two?
I have never looked into it but isnt there a multplayer aspect to this game??
I used to play 688 Hunter Killer in a virtual Navy back in the 90's and it was so much fun to be able to play against other humans. AI's are predictable but against another human the simulation became very real and very personal. Some missions were COOP and some were simply hunter and kill ... my favorite mission was one where there were 8 submarines in the water in close proximity and the goal was last man standing. It took me 6 hours to hunt down the last man but we called it a draw since we both had done such a good job of avoiding detection.
What a fabulous mission it would be to have U-Boat and Fleet Boats in a mission together and all human controlled. One protecting the convoy by listening for the enemy the other risking everything to come in for the kill.
