The Littoral Combat Ship is Designed to Defeat Growing Threats in the Coastal Water Battlespace


Standard equipped with Rolling Airframe Missiles (RAM), SeaRAM (17 and follow) and a Mark 110 gun that fires 220 rounds per minute.


More than a third of the hull is open and ready to take on new capability. LCS has Aegis-derived COMBATSS-21 combat management system to quickly add capabilities.


LCS can serve surface, anti-submarine and mine countermeasure missions. LCS can also deploy manned and unmanned aerial, surface or sub-surface missions.

LCS Features Overview

Mission Control Center

The MCC is enabled with the COMBATSS-21 Combat Management System. This system is built from Aegis Common Source Library and drives commonality among the fleet.


Automated ship reduces crew size, increases situational awareness and combat effectiveness.

Topside Reconfigurable Spaces

Three reconfigurable spaces allow for flexible armament including guns and missiles.

Airborne Mission Zone

Aircraft hangar has space for two H-60 helicopters or one MH-60 helicopter and one unmanned aerial vehicle.

Reconfigurable Spaces 1 and 2

LCS is 40% reconfigurable, and the space is the backbone of the ship. Space is reconfigurable to meet existing and emerging mission requirements.

Flight Deck

Flight deck is more than 1.5 times larger than most U.S. Navy surface combatants.

Water Jets

Enable agile maneuvering and top speeds of 40+ knots.

Gun Control Fire System

The Gun Fire Control System (GFCS) introduces multitarget tracking, improves the target identification range by two to three times over the current system and provides a five-times wider field-of-view and more than a 90° field-of-regard.

Over-the-horizon Capability

Integrating the Naval Strike Missile (NSM) on LCS makes LCS more lethal against longer-range threats. NSM gives LCS more than 10 times the range for surface target engagements.


The Surface Electronic Warfare Improvement Program (SEWIP) is an integrated shipboard combat system that provides a full suite of next generation electronic warfare capabilities.

Common Radar

Lockheed Martin is exploring ways to upgrade and deploy a common radar system across both the Freedom and Independence class variants of the LCS that increases lethality and survivability through improved accuracy.


Integrating Nulka – a rapid response active expendable decoy system - onto the LCS gives the vessel a more effective way to respond to anti-ship missiles and increases commonality across the fleet.


The strike length MK-41 Vertical Launch System (VLS) brings commonality across hardware, software, logistics, maintenance and support and expands mission options for the LCS with capabilities for land and surface attacks.

Directed Energy

Lockheed Martin is studying ways to install and test a directed energy weapon onboard a Freedom Class LCS, with the goal of improving LCS lethality and survivability.


Advanced Offboard Electronic Warfare (AOEW) is a self-contained electronic warfare pod that provides advanced ASM detection and response, working independently or in conjunction with SEWIP to detect, track and deter incoming threats.


USS Little Rock supports multinational Operation Martillo

USS Little Rock deployed in early 2020 to support the Martillo campaign – a multinational effort targeting illicit trafficking routes in coastal waters along Central America.


Littoral Combat Ship 19 (St. Louis) Delivered To U.S. Navy

Lockheed Martin (NYSE: LMT) and Fincantieri Marinette Marine delivered the future USS St. Louis, Littoral Combat Ship (LCS) 19, to the U.S. Navy.


The Need for Speed … to Capability

LCS offers the perfect recipe for speed to capability because it has modularity, open architecture and common U.S. Navy systems,” said Nicole Sanders, Senior Manager, Strategic Programs, Lockheed Martin.
