In 2003, the Navy launched its first experimental LCS, "Sea Fighter", designated as fast sea frame or FSF-1. In 2005, the SWATH-hulled "Sea Fighter" entered service as an experimental vessel using mission modules. As the "Oliver Hazard Perry", , and the classes were reaching the end of their lives, the U.S. Navy released the LCS requirement. In 2004, Lockheed Martin, General Dynamics and Raytheon submitted design proposals. It was decided to produce two vessels each (Flight 0) of the Lockheed Martin design (LCS-1 and LCS-3) and of the General Dynamics design (LCS-2 and LCS-4). After these are brought into service, and experience gathered on the design's usability and efficiency, the future design for the class would be chosen (Flight I). The ultimate decision was to fund both designs as two variants of the class. On 9 May 2005, Secretary of the Navy Gordon R. England announced that the first LCS would be named . Her keel was laid down on 2 June 2005 at Marinette Marine, Marinette, Wisconsin. The contract to build the ship was managed by Lockheed's Maritime Systems and Sensors (MS2) division, directed by Fred Moosally. On 23 September 2006, LCS-1 was christened and launched at the Marinette Marine shipyard. On 19 January 2006, the keel for the General Dynamics trimaran, , was laid at the Austal USA shipyards in Mobile, Alabama. LCS-2 was launched 30 April 2008.
