(April 22, 2019) The littoral combat ship USS Sioux City (LCS 11) arrives at Naval Air Station (NAS) Pensacola's Allegheny Pier, April 22, for a regularly scheduled port visit. The LCS is a fast, agile, mission focused platform designed to operate in near-shore environments, while capable of open-ocean tasking, and win against 21st-century coastal threats such as submarines, mines and swarming small craft.
