For those doing the maths at home:

An F35 who obligingly flies top-towards-you (not exactly something you can do, but hey, maybe they're turning) is all of 10m tall.

An AIM-120C can very comfortably hit a target at 100km.

At that range, the F-35 takes up 26 arcseconds, or 0.007 degrees. That's roughly about the size of this period, at a distance of 3 meters away.

Good luck spotting that in a sky of roughly the same colour, full of other objects.

    Just for reference: JWST has an optical resolution of 0.07 arcseconds. It’s a mirror 22 feet in diameter though, not something you’d put inside a missile guidance package.

    JWST operates in space, i.e. there is no atmosphere blurr to take into account.

    Oh yeah I’m not suggesting we make a missile with JWST mounted on the front!

    Well but I am!

    Although, we would still need to get it back here... Okay so first we send two more rockets after it! One to return it on and one with the/a human engineer on board to pack it back up.

    I mean we can hardly have it return while unpacked. That would damage the delicate heat baffles! And we need those to shield it from the rockt engine at the back of our missile so it doesn't start targeting itself because it no longer knows where it is/isn't...

    Yeah, sure. But that doesn't matter if you point the AI at it with a really good zoom lens, though. And then you have a ton of them, pointed in an directions, like the compound eye of a fly. F35 spotted.
