Don Kirlin, the owner of Air USA, has purchased 46 F/A-18 Hornets from the Royal Australian Air Force to be used for contractor adversary air support in the United States. The aircraft will be used to provide training for US military fighter pilots, replicating aerial threats from potential enemy nations. The purchase includes all of the RAAF's F/A-18 spare parts inventory and test equipment, valued at over a billion dollars. The jets will be operated by Air USA, a company that provides advanced flight combat training to the US military.
