On 30 April 2014, the Navy issued two Request for Information (RFI) to industry to give the LCS task force follow-on designs to Flight 0 ship models. One RFI was for design concepts and information on cost and lethality, and the other was for specific systems and technologies. Mission areas consisting of anti-air, surface warfare, anti-submarine warfare, and mine countermeasure missions will offer a range of mission and capability options based on the threat environment that will drive design work and costs. Options for the proposed small surface combatant were a modified version of the LCS, an existing alternate ship design, or an entirely new design.
