ATLANTIC OCEAN (May 20, 2023) Civilian contractors prepare to test a V-Bat unmanned aerial system's flight capabilities on the flight deck aboard the amphibious dock landing ship USS Carter Hall (LSD 50). Carter Hall is part of the Bataan Amphibious Ready Group and, with the embarked 26th Marine Expeditionary Unit, is underway participating in the Carrier Strike Group Four composite training unit exercise (COMPTUEX). COMPTUEX is the final pre-deployment exercise that certifies the Bataan ARG and 26th MEU's ability to conduct military operations through joint planning and execute challenging and realistic scenarios.
