The “G” (USAF, or did you fly the short-lived Navy “G”?) was a specialty platform, not too many were converted from “Es” and i think most were converted to unmanned drones and expended as targets some time ago.
USAF still has “Es” and some RF-4Cs in inventory as target drones. But those are running out and they’re starting to convert F-16s.
Flew the “G” stateside, mostly flew the “B” and “J” mods.
I liked the “G” , ( Navy had a dozen of them (One was lost over the North) it had a downlink capibility that allowed hands-off carrier landings, but the Navy didn’t,they stripped all the electronics gear out of them in ‘67 (I think)and returned them to the “B”status.
