LCS 19

A littoral combat ship (LCS) is a relatively small surface vessel designed for littoral warfare in near-shore operations. There are two LCS ship classes deployed by the United States Navy. The LCS was "envisioned to be a networked, agile, stealthy surface combatant capable of defeating anti-access and asymmetric threats in the littorals", although their ability to perform these missions in practice has been called into question.
