USS Sioux City (LCS-11) is a Freedom-class littoral combat ship of the United States Navy. She is the first ship named after Sioux City, the fourth-largest city in Iowa.[7][8]

Design[]

Main article: Freedom-class littoral combat ship

In 2002, the U.S. Navy initiated a program to develop the first of a fleet of littoral combat ships.[9] The Navy initially ordered two monohull ships from Lockheed Martin, which became known as the Freedom-class littoral combat ships after the first ship of the class, USS Freedom.[9][10] Odd-numbered U.S. Navy littoral combat ships are built using the Freedom-class monohull design, while even-numbered ships are based on a competing design, the trimaran hull Independence-class littoral combat ship from General Dynamics.[9] The initial order of littoral combat ships involved a total of four ships, including two of the Freedom-class design.[9]  Fort Worth is the second Freedom-class littoral combat ship to be built.

Sioux City includes additional stability improvements over the original Freedom design; the stern transom was lengthened and buoyancy tanks were added to the stern to increase weight service and enhance stability.[11] The ship will also feature automated sensors to allow "conditions-based maintenance" and reduce crew overwork and fatigue issues that Freedom had on her first deployment.[12]

Construction and career[]

The ceremonial “laying of the keel” was on 19 February 2014, at Marinette, Wisconsin.[4] The ship was constructed by Fincantieri Marinette Marine and launched on 30 January 2016 after being christened by her sponsor Mary Winnefield, wife of Admiral James A. Winnefeld Jr., USN.[13][14]

Sioux City was delivered to the Navy by Lockheed Martin and the Marinette Marine shipyard on 22 August 2018 along with sister ship Wichita in a double delivery.[2] The ship was commissioned at the United States Naval Academy in Annapolis, Maryland on 17 November 2018,[3] and then assigned to Littoral Combat Ship Squadron Two. Sioux City will be assigned to the Fifth Fleet in the Persian Gulf.[15]
