A NATO E-3 Sentry from Geilenkirchen NATO Air Base breaks away from a KC-135 Stratotanker from the 100th Air Refueling Wing, RAF Mildenhall, England, after receiving fuel over Germany, July 17, 2020. The 100th ARW is the only permanent U.S. air refueling wing in the European theater, providing the critical air refueling "bridge" which allows the Expeditionary Air Force to deploy around the globe at a moment's notice.
