You are both right, we are not to modify USNI data because it's licenced by USNI. But really I never intended to change USNI data itself, only to add additional gameplay notes just like SCS did. Or if not, at least a separate table of contents entry with mod documentation. So USNI (or even SCS) text would be not touched at all. Maybe wrong words used while asking...
P.S. The only USNI data I would LOVE to change is the 50nm Maverick range
Come on, this missile woudln't reach 50nm even unguided in supersonic lofted ballistic launch :P , I doubt if it reached 25nm this way. If lofted at Mach 1.5 from 50k feets and used optimal trajectory then MAYBE it would reach (or rather glide) to 30-33nm...
50nm ??? NO WAY :P
