U.S. Army crews take on F-22 Raptor refueling at Keen Sword 27 exercise in Japan

US Army fuel specialists supported F-22 Raptor fighter operations during the Keen Sword 27 exercise in Japan, refuelling aircraft from the 525th Expeditionary Fighter Squadron with Army equipment. Personnel from the 593rd Corps Sustainment Command had completed preparation at Joint Base Lewis-McChord to apply Air Force safety procedures to fixed-wing aircraft refuelling. In Japan, crews coordinated with Air Force maintainers, tested fuel quality and monitored pressure, transfer flow and static-electricity hazards during aircraft servicing. The cross-service arrangement was an exercise in distributed logistics and ground-support flexibility, not an announcement of permanently transferring F-22 maintenance or fuel operations to the Army.
