Eh I was talking about the 1980's, as the OP mentioned, otherwise I would have mentioned C-17Actually only 2 of those could. The C-141 has been retired for over 10 years. And the KC-135 doesn't have anywhere to mount it. But putting them on C-130 gunships sounds awesome!
KC-135 has been converted into just about everything, command posts, jamming aircraft, sigint aircraft, observation aircraft, weather aircraft, should be able to mount it in a similar way to the AC-130 after a similar amount of conversion as any of those conversions, though probably should have just said C-135
