Greatest challenge was converting analog flight controls to digital. Most of the fleet was retired due to cost of that even if the airframes were still good. This was in the post-Vietnam budget cuts. Nothing to do with technology or capability.

You have to wonder if they went through the fleet and picked the most beat-up ones for the treaty…
