SEA OF JAPAN (Sept. 29, 2022) The U.S. Navy's only forward-deployed aircraft carrier, USS Ronald Reagan (CVN 76), and the guided-missile cruiser USS Chancellorsville (CG 62), steam in formation with Republic of Korea (ROK) navy ships in the Sea of Japan. The Ronald Reagan Carrier Strike Group (CSG) is participating with the ROK Navy in Maritime Counter Special Operations Exercise (MCSOFEX) to strengthen interoperability and training. The U.S. routinely conducts CSG operations in the waters around the ROK to exercise maritime maneuvers, strengthen the U.S.-ROK alliance, and improve regional security.
