I think we are more likely to see a Laser Weapon onboard which also deals this defense before we ever see a hard kill missile, so many variables and ways in which the interceptions have to be perfect and what happens when we see something like a Starstreak MIRV type air to air missile, the starstreak manpad already have 3 dart submunitions that get released after the missile has fired and traveled up to a certain distance, what if someone does that with a air to air missile. waay too many complication where now to defeat a single missile you are firing multiple interceptors and you are able to track each independent submission. A very difficult ask if you ask me, trying to have more interceptors than the other guy has missiles with submunitions, plus an additional dedicated radar to detect and track it, and b/c its an air to air missile, its incredibly maneuverable unlike a ballistic trajectory that can be predicted.
