Actually I didn't. And which satellites were the intended targets?
My first assignment in the USAF was at VAFB working on the space shuttle program. That mission doesn't sound familiar. But, if we were going to snag Russian satellites it would have been above my classification at that time.
It’s been awhile since I read about that, so I did some searching. It seems the long cross range glide capability was due to the military requirement to have a single orbit abort return to California after a launch at Vandenberg.
Apparently, in addition to that, there were military plans to do single orbit missions to snag satellites from polar orbits, both ours and theirs. Of course, there never was a Shuttle launch from Vandenberg, but the Shuttle was stuck with the large wings.
