It’s thought they just finished putting new wings on the fleet a couple years ago. I know they were in the process, but not sure if the program cancelled before they completed the fleet.
They talked about it for a long time while the AF Brass and certain members of Congress were trying to kill it. It was not until the 35 got into some serious quals, I think was at Red Flag, that they just had to admit the 35 is not a close air support platform anywhere close to the Warthog, especially if it were upgraded.
