I am wondering whether this question is in scope or not. If we had a Military.SE, it would be easy to redirect this question there, but that is not the case.
It seems to me like this question strictly has to do with the navigational system of a missile and thus is not related to aviation. Furthermore, the elements discussed in that question are not equally applicable to aircraft. As such, I believe it is off topic.
As said in the answer to another meta question:
we want to stay away from questions about the tactical/strategic function of the ordinance, it's damage capabilities or it's guidance system.
BUT, I have not voted to close, as I realize it is very close to a borderline. Terminal phase navigation on missiles can be used to target aircraft (but then again, so can shotguns, and I'm pretty sure those are off topic).
We do have a ``missiles'' tag, but questions with that tag usually do have aircraft somewhere in the question.
- missiles being shot from planes
- or missiles that target planes
- or systems that protect planes from missiles
A lot has been said about this question, as an Area51 question, another meta post and a chat discussion can prove. But does the question at the top fall out of scope?
