PHILIPPINE SEA (Oct. 26, 2020) Aircraft from the U.S. Navy, U.S. Marine Corps, Japan Maritime Self-Defense Force and Japan Air Self Defense Force fly in formation above the Arleigh Burke-class guided-missile destroyer USS Barry (DDG 52) during Keen Sword 21. Keen Sword is an example of the strength of the U.S.-Japan Alliance, the foundation of peace and security in the Indo-Pacific region for more than 60 years. The relationships built and maintained during these events are critical to our shared capability to respond to contingencies at a moment’s notice.
