Kaiser-class underway replenishment oiler USNS Pecos (T-AO 197) during a replenishment at sea 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.
