U.S. Marines, with Marine Corps Installations Pacific, and Airmen with the 355th Expeditionary Fighter Squadron pose for a photo during a hot-pit refueling training no Kadena Air Base, March 9, 2022. The training refined and enhanced the multiple aircraft platform skills of participating Marines, focusing on hot-pit refueling the F-35A Lightning II with limited time, simulating an operational environment. During hot-pit refueling, the aircraft maintains a running engine, which decreases the response time in an operational environment. - U.S. Marines, with Marine Corps Installations Pacific, and Airmen with the 355th Expeditionary Fighter Squadron pose for a photo during a hot-pit refueling training no Kadena Air Base, March 9, 2022.
