The Coronado (LCS 4) is the second ship in the Independence-class littoral combat ships. She is the third ship of the United States Navy to be named after Coronado, California. The keel was laid on December 17, 2009.

January 10, 2012 The Pre-Commissioning Unit Coronado entered the water for the first time, after a complex operation in Mobile, Ala. In a three-step process, self-propelled modular transporters (SPMTs) lifted the entire ship and keel stands almost three feet and moved the Littoral Combat Ship into the moored dry dock. The LCS and dry dock were then transported down river by tug to BAE Systems Southeast Shipyard where the ship was ultimately floated free of the keel stands, and was manoeuvred from the drydock. The vessel was then towed back upriver to Austal’s facility.

January 14, PCU Coronado was christened during a 10:00 a.m. CST ceremony at Austal USA Shipyard in Mobile, Alabama. Mrs. Susan Ring Keith served as sponsor of the ship. Her father Vice Adm. Stanhope C. Ring commanded an aircraft carrier air group during the Battle of Midway. The prospective commanding officer of the Blue crew is Cmdr. John Kochendorfer and Cmdr. Michael Johnstons is CO of the Gold crew.
