Like the title says, I think there should be a spy plane unit type. With all the stealth changes and now the production facility changes I think there is a clear recon role. I use planes to gather intelligence all the time and I assume other players do as well, but the best I can do is send interceptors which the enemy immediately sees. Normally that's fine, you just achieve air superiority first, then you know everything, but it would be better if there was a stealth aircraft that had poor combat capabilities but long range and high speed.
Interceptors can already detect stealth units anyway, this would give people an incentive to maintain patrols other than defending a stack and make the air war much more interesting and consequential. It could justifiably be added to either the aircraft or secret tech trees.
