A Norwegian air force F-35A Lighting II aircraft receives fuel from a U.S. Air Force KC-135 Stratotanker aircraft assigned to the 100th Air Refueling Wing, Royal Air Force Mildenhall, England, during exercise Castle Forge over Norway, Nov. 4, 2021. Training with joint and combined allies and partners increases lethality and enhances interoperability, allowing U.S. forces to counter military aggression and coercion by sharing responsibilities for common defense. 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.
