In 2019, several A-10Cs underwent wing replacement, which included new paint, by the Ogden Air Logistics Complex on Hill Air Force Base (AFB), Utah.

They were the last of 173 A-10s to get the new wing upgrade. I’m not sure if this if the primer paint as most A-10s I’ve seen get re-painted are primered with a zinc yellow paint.
