Standard Link 16 IDs work, for the most part, in all cockpits these days. Even Typhoon these days!
I would not envisage any issues with an E-7 operating within the NATO hierarchy. Any issues are generally very easy to work around but, I’m quite sure that it’s link architecture would embed without any problems.
More importantly, the E-7 has very comfortable seats, unlike the E-3 back destroyer!
