Still to be determined is whether the NGJ system will be exportable to other JSF-buying nations. The NGJ is designed to defend the F-35 against heavily protected surface-to-air missiles (SAM) and suppress integrated enemy air defenses such as the SA-20.
Advanced SAM systems might be used by Iran, for example, to defend nuclear weapons, ballistic missile and key command-and-control sites. U.S. analysts say only a stealthy, high-flying, supercruise aircraft can avoid destruction in the heart of such defenses.
I'd like to point out that deep strike is typicaly made by a strike package, not just by a formation of fighters. That means that the Joint Force will already proven jammer kit to support that strike package.
Also, I seriously doubt F-35 is how you go after nuke sites. There are other ways to peel that onion.
The future may include the NGJ on UAV's being used to escort jam with the f-35, but it doesn't seem to be a requirement
As soon as you start jamming, "stealth" becomes somewhat moot, right?
But you did read my mind.
