There was supposed to be one coming out called Destroyer command or something. I dont know more than that about it.
Its a neglected area though. There was a game called fighting steel about 3 years ago but I wouldnt really call it a sim. Its of a tactical level wargame. You control surface warships in it. However, the graphics are dated, it uses statistical odds rather than physics to determine hits, making it more a wargamer type as opposed to simulation. Also, there are lots of things missing. Aircraft, land, and many other things make this not that great of a game. Its kind of fun but it could have been so much better. Janes Fleet command is another, again not really a simulator so much as it is a strategy game. The Destroyer command one is your best bet whenever it comes out I think.
