Our version was various versions of the KC-135 back then.
We had a KC-135 Burning Wind back-ender - he’s gone now - RIP - signals collection
The KC-135 Cobra Ball, of course, collected images and film (of some sort or another)
Then there was the E-8 J-STARS aircraft.
There may be other, newer variants of such. Dunno
Cobra Ball, Combat Sent. Two different missions.
Combat Sent is a trip.
