Lockheed Martin privately proposed it to succeed the retired Lockheed SR-71 Blackbird. The SR-71 Blackbird retired in 1998, leaving what was considered a coverage gap between surveillance satellites, manned aircraft, and unmanned aerial vehicles for intelligence, surveillance and reconnaissance (ISR) and strike missions. With the growth of anti-satellite weapons, anti-access/area denial tactics, and counter-stealth technologies, a high-speed aircraft could penetrate protected airspace and observe or strike a target before enemies could detect or intercept it. The proposed reliance on extremely high
Littoral combat ship 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 .
