ANG F-16 gets new dark gray paint Published Dec. 18, 2019 By Senior Master Sgt. Vincent De Groot 185th Air Refueling Wing Sioux City, Iowa -- This week the Air National Guard Paint Facility at the 185th Air Refueling Wing, Sioux City, Iowa rolled out a freshly painted, all dark gray U.S. Air Force F-16 Falcon for the Texas Air National Guard, 149th Fighter Wing. The new, single color is a recent departure from the older paint scheme, which was about ten years old. The new procedure helps minimize aircraft downtime which increases the facilities availability and efficiency. The Texas based aircraft is now ready to return to its home at Joint Base San Antonio.
