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.
Littoral combat ships are comparable to corvettes found in other navies. The Freedom class and the Independence class are the two LCS variants. Each is slightly smaller than the U.S. Navy's earlier Oliver Hazard Perry-class frigate but larger than Cyclone-class patrol ships. Each has the capabilities of a small assault transport, including a flight deck and hangar for housing two SH-60 or MH-60 Seahawk helicopters, a stern ramp for operating small boats, and the cargo volume and payload to deliver a small assault force with fighting vehicles to a roll-on/roll-off port facility. Standard armaments include Mk 110 57Â mm guns and RIM-116 Rolling Airframe Missiles. They are also equipped with autonomous air, surface, and underwater vehicles. Possessing lower air defense and surface warfare capabilities than destroyers, the LCS emphasizes speed, flexible mission modules, and a shallow draft.
