The USS Freedom (LCS-01) at sea on February 22, 2013.
The Freedom-class is one of two classes of littoral combat ship built for the United States Navy.

The Freedom-class was proposed by Lockheed Martin as a contender for USN plans to build a fleet of small, multipurpose warships to operate in the littoral zone. Two ships were approved, to compete with the Independence-class design offered by General Dynamics and Austal for a construction contract of up to 55 vessels.

As of 2013, two ships are active and a third is under construction. Despite initial plans to only accept one of the Freedom and Independence variants, the USN has requested that Congress order ten ships of each variant.
