Aerial Spray Mission

Untitled Document


The Department of Defense (DoD) tasks the 910th Airlift Wing at Youngstown Air Reserve Station (YARS), Ohio to maintain the DoD’s only large area fixed-wing aerial spray capability to control disease-carrying insects, pest insects, undesirable vegetation and to disperse oil spills in large bodies of water.  Missions may be executed in combat areas, on DoD installations or in response to disasters/emergencies as declared by the President of the United States.


The 757th Airlift Squadron pilots, navigators, flight engineers, spray operators/loadmasters, and entomologists conduct aerial spray missions using six C-130H aircraft equipped with the Modular Aerial Spray System (MASS). These systems are maintained by 910th MX support personnel assigned to the spray mission. YARS houses one of four EPA-approved Training Centers for DoD Pesticide Applicator Certification serving both the continental U.S. and overseas DoD pest management facilities.


Col. James D. Dignan is 910th Airlift Wing commander, U.S. Air Force Reserve Command (AFRC).  When activated, the unit is gained by Air Mobility Command (AMC), at Scott Air Force Base, Illinois.
