The US Navy has confirmed that its future Freedom-class littoral combat ship, USS Sioux City (LCS 11), will be commissioned in the city of Annapolis, Maryland.

USS Sioux City has been named to honour citizens of Sioux City and the state of Iowa, to recognise their support and contributions to the military. Sponsor of the ship will be Mary Winnefeld, wife of retired admiral James Winnefeld.  

The 378ft-long USS Sioux City vessel is expected to be commissioned later this year.

The LCS class is being built in two variants, the Freedom-class and Independence-class. Work is being carried out by two industry teams led by Lockheed Martin and Austal for each vessel respectively. 

Lockheed Martin are set to construct the Freedom-variant ships at Fincantieri Marinette Marine in Marinette, Wisconsin.

"USS Sioux City features a waterline beam of 57ft and can displace nearly 3,000t; it will also be capable of operating at speeds of more than 40k."

The fast, mission-focused vessels have been designed specifically for operations in near-shore and open-ocean environments, and can be deployed to defeat a wide range of threats, including mines, quiet diesel submarines and fast surface craft.

LCS will be equipped with reconfigurable payloads, known as mission packages, which can be changed out quickly as and when demanded by combat requirements.

These mission packages feature special detachments that enable the deployment of both manned and unmanned vehicles, as well as sensors in order to support mine, undersea and surface warfare missions.
