ATLANTIC OCEAN (July 3, 2023) Sailors maintain safe navigation aboard the Arleigh Burke-class guided-missile destroyer USS Carney (DDG 64) during a replenishment-at-sea with the Military Sealift Command fleet replenishment oiler USNS John Lenthall (T-AO 189), July 3, 2023. Carney, part of the Dwight D. Eisenhower Carrier Strike Group, is underway in the Atlantic Ocean participating in the Carrier Strike Group Four composite training unit exercise (COMPTUEX). COMPTUEX is an intense, multi-week exercise designed to fully integrate a carrier strike group as a cohesive, multi-mission fighting force and to test their ability to carry out sustained combat operations from the sea.
