The 18th Maintenance Group, with its five squadrons, maintains combat-ready aircraft to support air operation taskings directed by the commander of U.S. Indo-Pacific Command through Pacific Air Forces and Fifth Air Force. The group manages more than $6 billion in resources, including 54 F-15 Eagle, 15 KC-135 Stratotanker, 2 E-3 Sentry and 9 HH-60 Pave Hawk aircraft.
The 18th MXG consists of over 2,300 aircraft maintainers and munitions handlers, supporting sortie production for a 18,000-hour annual flying-hour program. The group also provides maintenance support and facilities for sister services and assigned to or transiting Kadena. The group's five squadrons are the 18th Aircraft Maintenance Squadron (AMXS), 718th Aircraft Maintenance Squadron, 18th Equipment Maintenance Squadron (EMS), 18th Component Maintenance Squadron (CMS), and 18th Munitions Squadron (MUNS).
The 18th AMXS is responsible for the maintenance, generation and mobilization of the only F-15s in the Asian and Western Pacific region.
The 718th AMXS maintains the KC-135, HH-60 and E-3 aircraft. The squadron provides the air refueling, aeromedical evacuation, combat search and rescue, and air battle management assets in the region.
The 18th EMS supports heavy maintenance for Kadena-assigned aircraft, F-15s, KC-135s and HH-60s; and limited maintenance to associate H/MC-130, RC-135; and transient C-5, C-17 and C-130 aircraft.
The 18th CMS provides maintenance on electronics for propulsion, avionics and airframe accessory sub-systems for all assigned aircraft. The 18th CMS maintains the only four-bay engine test cell facility in Pacific Air Forces. It is also responsible for test, measurement and diagnostic equipment services to the wing and associate units, as well as maintenance services essential to daily aircraft sortie production and unit deployments.
The 18th MUNS operates the Air Force's largest conventional munitions storage area supporting activities of all U.S. services and Japan Ground and Air Self-Defense Force. The squadron provides the wing and associate units with munitions for more than 6,000 annual sorties. It maintains a war reserve materiel stockpile for U.S. forces throughout the Pacific theater valued at $947 million with 475 facilities and 200 vehicles within a 5,900-acre area.
