Defensive warning: AN/AAR-57

Countermeasure AN/ALE-47

I don't think they had radar lock, I think they were firing IR missiles. They wouldn't have had much time to respond, and IR missiles are normally much smaller than beyond visual range radar missiles, which would explain how all 6 pilots survived.

Rumor is there was a problem with the IFF identification system sync. If that's true, the Kuwaiti pilot just saw 3 jets coming into their airspace with no IFF working, under a very compressed timeframe with lots of inbound UAS and potentially aircraft.

"AN/AAR-57" Yes the small yellow subwoofer looking things that people speculate endlessly about. Supposedly BAE systems marketing released a picture of the whole system LOL, who needs spies if you have a marketing dept, also supposedly just about everything about this is classified. They supposedly come in four packs and there are "many" public pictures of them one under each cockpit rail on the F15 and the other two are unknown location? Or maybe the mythology online that they come in four packs is false and they actually come in two packs which seems more likely. Plausibly they install 4-packs on helicopters not fixed wing.

I could see some logic in not putting cams pointing forward because theoretically the pilot is looking where they're going and not putting one facing back because flight time to impact is so low they can't evade anyway, but a side attack is survivable if detected early enough... Also facing back they're going to be "seeing" their own exhaust most of the time.

The total non-reaction by the pilots in the public videos would indicate that if those planes even had -57s they were not working or not working well enough to matter or not working fast enough to matter.

I would agree some monster sized BVR missile will be easier to detect. In practice does it matter if the missile detector works at short range if the attacker would likely be in guns mode at short enough range anyway?
