the Oklahoma Air National Guard moved from Will Rogers Air National Guard Base to Tinker and became an associate unit of the 507th Air Refueling Wing, redesignating as the 137th Air Refueling Wing and operating the same aircraft. The number of aircraft operated by the 507th and 137th was simultaneously increased by the transfer of KC-135s from the 939th Air Refueling Wing. The affiliation continued until July 2015, when the 137th began to convert to the Beechcraft MC-12W Liberty. In conjunction with this transition the 137th is returning to Will Rogers, where it will become the 137th Special Operations Wing and terminate its affiliation with the 507th. The wing participated in Operation Enduring Freedom, the Global War on Terrorism, and in Operation Iraqi Freedom. In 2005, it sent forces to assist with the recovery following Hurricane Katrina.
