From the Document: "On October 24, 2019, the U.S. Air Force issued a final request for proposals declaring its intent to acquire a new type of aircraft. The OA-X light attack aircraft is a small, two-seat turboprop airplane designed for operation in relatively permissive environments. The announcement of a formal program follows a series of Air Force 'experiments' to determine the utility of such an aircraft."
