F35 is as maintenance heavy as an F-16.
Lol, I still stand by my word. F-35s would destroy any 4th generation air force.
F35 still has many drawbacks. Though it would be interesting to see how it would fair against a NATO/MAJOR-NONE NATO alleys air force. A while back a read that F16s were able to track and take down F35s in war games.
Stealth fighters by nature are far more maintenance heavy. The F35 is a complete system consisting of ground detection pods, EW pods, all built into the airframe itself. Even the stealth coating has to be maintained to pristine as even a small scratch or bird poop can cause major deviations in the RCS leading to the stealth fighters detection. Taking these minor details in prospective it is far more maintenance heavy than the F16s.
Also Pakistan has apparently inducted Chinese ground based radars capable of detecting stealth fighters. Anyways I doubt Pakistan or Israel would ever have any conflict. Way to far from one another and the US would prevent it far before
