Hi guys,
I'm pretty sure the US Navy is not going to give permission, to be honest. :-
Why not? There already have been many games featuring US Navy ships/ subs eg USS Ticonderoga, USS John Young, Strike Fleet, PHM Pegasus, Operation Spruance, Harpoon Classic, Harpoon Adbvanced Naval warfare, Silent Hunter 1 & 2, Tom Clancy's SSN, 688 Attack Sub, 688 Hunter Killer, Fleet Command, Red Storm Rising, Destroyer, Destroyer Command etc etc etc. Honestly this permission thing is getting out of hand, I can understand it when dealing with commercial companies who don't wish their logos used indescriminately but not so much with public institutions like navies. The Sonalysts games were originally developed using publically available Jane's data whilst the current releases feature unclassified USNI (US Naval Institute) data.
