It hit an apogee of over 3,600 miles? That’s deep into outer space and could take out a lot of satellites. Too bad we don’t have a space-based defense system for such vehicles.
Not really. Space is really big and satellites are really small, widely scattered and moving fast. ASAT is a whole 'nother critter compared to ballistic trajectory.
And we do have effective space defense. I've seen it, touched it, know how it works.
