Thinking about it some more, a radar altimeter is only effective to ~2000 feet so it’s probably going to be a relatively close range highly-directional beam which would make it harder for a seeker head to find but also means you’d need a truck close to the airfield perimeter, painting aircraft on final approach. WRT last minute painting, I guess the E model would help a bit with that: > the AGM-88E Advanced Antiradiation Guided Missile (AARGM), features the latest software, enhanced capabilities intended to counter enemy radar shutdown At 870k USD a pop you wouldn’t want to be lobbing a lot of them, though - as you say, it’s going to cheaper to build jammers than countermeasures to destroy them.
