The 137th Special Operations Wing of the Oklahoma Air National Guard has recently received its new OA1K Sky Warden Light Attack Plane, and is beginning training. This marks a significant milestone for the US Air Force Special Operations Command's Light Attack program.

The United States will be the only operator of the OA1K model for the time being. Initially, the Air Force had plans to purchase 75 of these Aircraft but has scaled back their plans in recent years.
