The USS Freedom and USS Independence are the pioneering warships changing the face of battle on the sea with cutting edge design. Go inside the rigid testing that these ships must face to become part of the Navy. From a simulated high-speed attack to test the ships' guns and cannons to helicopter launches and technical failures, watch these ships attempt to achieve their mission objectives to ultimately be integrated into the U.S. Navy's Surface fleet.
