Don't worry about HOW it could be done... just tell me how it should BE.
Thanks for the information guys, I'm going to shoot to have this done in a day or two, so keep it coming.
(BTW, the radars respect the earth curvatures if we set them to and the game engine already has built in plenty of features to account for different detection ranges against targets with varying radar profiles)
Adding the high diving capability is like adding a whole new class of weapons so that might have to wait, although I can easily make their cruise altitude higher than other missiles, as well as make all the seaskimmers actual seaskimmers.
