Many, many years ago, I was involved with the “A-Sat” or, anti-satellite rocket engine. It was a relatively small rocket engine which could be mounted to the belly of an F-15 which would climb at a certain angle and launch it.
A bunch of us young engineers were to mount it in a test cell for firing. I asked one of the older guys what kind of warhead would be mounted when it was used. He said “none”. It was simply an inertia weapon! It only had to get in the path of its target and run into it. Made perfect sense. Satellites are pretty fragile...
Sounds like a fun project to be on!
Have you done similar things since?
