SOUTH CHINA SEA (Feb. 12, 2017) - The littoral combat ship USS Coronado (LCS 4) transits the South China Sea during training. Currently on a rotational deployment in support of the Asia-Pacific rebalance, Coronado is a fast and agile warship tailor-made to patrol the region's littorals and work hull-to-hull with partner navies, providing 7th Fleet with the flexible capabilities it needs now and in the future.
