U.S. Airmen assigned to the 100th Air Refueling Wing secure cargo on a KC-135 Stratotanker aircraft during exercise Castle Forge at Royal Air Force Mildenhall, England, Nov. 1, 2021. The ability to quickly respond and reassure allies and partners rests upon the U.S. Air Force’s forward and ready presence in Europe. In addition to F-15 Eagle aircraft operations in the Black Sea Region, Castle Forge encompasses the USAFE-wide Agile Combat Employment capstone event. Castle Forge’s components will better enable forces to quickly disperse and continue to deliver air power from locations with varying levels of capacity and support, ensuring Airmen are always ready to respond to potential threats.
