In January 2011, Lockheed and Austal won a fixed-price incentive contract to design and build a total of 20 LCS ships between 2011 and 2015. The Lockheed Martin team includes Marinette Marine shipyard, Bollinger Shipyards, Gibbs and Cox naval architects, Izar of Spain, as well as Blohm and Voss naval shipbuilders.General Dynamics and Austal proposed the Independence-class of littoral combat ship, based on a trimaran hull. The consortium began construction on the ship in Marinette, in October 2019.In September 2018, the US Navy awarded a contract to the consortium to build PCU Beloit (LCS-29). The operational availability will be 95%.A core capability will be the deployment of Fire Scout unmanned air vehicle and the unmanned ribbed boat, Spartan unmanned surface vehicle, equipped with a basic payload of navigation radar, infrared camera and video camera.Mission modules will have the capability to be changed, tested and available to be deployed within 24 hours. In October 2007, the US Navy terminated the contract for this vessel.In April 2008, the US Navy issued a request for proposals to the two companies for three LCS ships. It was launched in September 2006.Builder’s sea trials began in July 2008. (U.S. Navy photo by Lt. Jan Shultis/Released)

The keel for USS Freedom (LCS-1) was laid in June 2005 at the Marinette Marine shipyard in Wisconsin. The General Dynamics Independence-class design is a trimaran with a slender stabilised mono-hull.The sea frames of both designs accommodate the equipment and crew for core LCS missions and special missions. The deck can launch and recover the General Dynamics Robot Systems was awarded a US Navy contract to develop the common launch and recovery system (CLRS) of unmanned and other watercraft for the LCS in July 2008.The ships will carry provisions for 21 days before replenishments and also be able to replenish underway. It had previously been planned that orders would be placed for nine flight 1 (second-generation) LCS ships during 2008 and 2009, for ship commissioning during the period 2010 to 2012.The contract for the Coronado, LCS-4, was awarded to General Dynamics in April 2009. In April 2007, the USN terminated the contract for LCS-3.In the Defense Department budget in April 2009, defence secretary Robert Gates guaranteed the US Navy’s commitment to the LCS programme. If you continue to use this site we will assume that you are happy with it. The littoral combat ship (LCS) is a new family of surface ships for the US Navy. General Dynamics was awarded the contract to build LCS-4 in December 2006. However, the strategy for launch and recovery for waterborne craft and aircraft are different for each design. The keel for USS St Louis (LCS-19) was laid in April 2017 and it was launched in December 2018. The semi-submersible, the AN / WLD-1 with an ASW mission system, tows a remote-towed active source (RTAS), a multiband transducer, with a remotely towed array multi-function sonar.The ASW module includes systems to be deployed from the MH-60R helicopter (mk54 torpedoes, sonobuoys, Raytheon AN / AQS-22 airborne low-frequency sonar) and unmanned surface vehicles, USVs (dipping sonar, multi-static active sonar and ULITE ultra-lightweight towed array).General Dynamics Robotics was awarded a contract for four USVs for the ASW module in October 2006.The 11m Fleet-class USV weighs 7.7t, has a payload of 2,270kg, a speed of 35k and is capable of operating continuously for more than 24 hours.The SUW module includes a General Dynamics mk46 30mm cannon (also used in the rapid airborne mine clearance system and the US Marine Corps expeditionary fighting vehicle), which fires at up to 200 rounds a minute, and a version of the US Army’s non-line of sight – precision-attack munition missile system.The NLOS launch system and precision attack missile are being jointly developed by Lockheed Martin and Raytheon. Her keel was laid on 11 July 2009, she was launched in December 2010 and completed sea trials in October 2011. The Lockheed Martin design of the mono-hull lifts the body of the hull.With the slender stabilised mono-hull, the General Dynamics trimaran design uses two outriggers, which move the displacement upwards and reduce the wetted surface. The littoral combat ship is a fast, agile, networked surface combatant designed to operate in the near-shore environment, while capable of open-ocean tasking, and win against 21st-century coastal threats such as submarines, mines, and swarming small craft. They achieve sprint speeds of over 40k and long-range transit distances of more than 3,500 miles.
