OK, say push came to shove. What about the logistics of a space based system already engaged, if they had not been already attacked and destroyed by anti-satellite weapons?
I don’t know, but it seems to me that a laser space based system would have a better chance of defending itself from an incoming object than an aircraft system which requires a significant chain of support to keep it flying in the theater of operation.
The main problems I see with aircraft based platforms are where and when to deploy them. As most actors out there such as Iran would likely not launch from their own territory it would be easy to get around such a system.
