What good is defensive radar if it is turned off?
You turn it on when you really need it. We never did in my sefvice (we did pack up to go to Israel in ‘74, but didn’t- I think Nixon just wanted the Russians to think about that)
For other reasons we and Israel are no threat to their bases.
I guess the homemade drones that are are handled by other means.

Pretty good, actually, when equipped with a Tracking Adjunct (telescope) System.
