SOUTH CHINA SEA (July 12, 2021) Sailors prepare to launch a rigid-hulled inflatable boat for a man-overboard drill aboard Independence-variant littoral combat ship USS Charleston (LCS 18). The littoral combat ship (LCS) is a fast, agile, mission-focused platform designed to operate in near-shore environments, winning against 21st-century coastal threats. The LCS is capable of supporting forward presence, maritime security, sea control and deterrence. (U.S. Navy photo by Mass Communication Specialist 3rd Class Adam Butler)
