They only built 15 and and only two display models with inert motors are left now. They are 20 years old anyhow and if any live ones were left the motors would probably just explode. On top of that there aren't any F-15s modified to launch it any more.I thought we tested ASAT missiles launched from F-15s back in the '80s. Can't we just use one of those? Or, perhaps, the satellite in question is too high.
