Independence-class littoral combat ship USS Coronado (LCS 4) launches the first over-the-horizon missile engagement using a Harpoon Block 1C missile during an exercise. USS Coronado (LCS-4) is an Independence-class littoral combat ship. She is the third ship of the United States Navy to be named after Coronado, California. The contract was awarded to General Dynamics-Bath Iron Works in May 2009 for the construction of LCS-4.
Coronado is the second littoral combat ship (LCS) to feature a high-speed trimaran hull and will be designed to defeat littoral threats and provide access in coastal waters for missions such as mine warfare, anti-submarine warfare and surface warfare. There are two different LCS hull forms – the Independence-class aluminum trimaran, and the Freedom-class semiplaning monohull designed and built by Lockheed Martin. These seaframes will be outfitted with reconfigurable payloads, called mission packages, which can be changed out quickly. Mission packages are supported by special detachments that will deploy manned and unmanned vehicles and sensors. Coronado was built by Austal USA in Mobile, Alabama.
Starting with LCS-4, the Independence class carries standard 7 metres (23 ft) long rigid-hulled inflatable boats, and improvements in corrosion protection and propulsion.
