Four Japanese Air Self Defense Force F-2s, one U.S. Air Force B-52H Stratofortress, and seven U.S. Air Force F-35A Lightning IIs fly in formation over the Pacific Ocean during Operation Iron Dagger, Dec. 9, 2021. The exercise signals the continuing effort to support the U.S. Indo-Pacific Command’s dynamic force employment concept through agile combat employment, which supports the National Defense Strategy efforts to conduct training with allies while maintaining global peace and security.
