USS Sioux City (LCS-11) was 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.[9][10]

Design

In 2002, the Navy initiated a program to develop the first of a fleet of littoral combat ships.[11] 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.[11][12] Odd-numbered 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.[11] The initial order of littoral combat ships involved a total of four ships, including two of the Freedom-class design.[11] Sioux City is the sixth 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.[13] 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.[14]

Construction and career

The ceremonial “laying of the keel” was on 19 February 2014, at Marinette, Wisconsin.[2] 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.[3][15]

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.[4] The ship was commissioned at the United States Naval Academy in Annapolis, Maryland on 17 November 2018,[5] and then assigned to Littoral Combat Ship Squadron Two.

In September 2020, Sioux City was assigned to the US Southern Command with a United States Coast Guard law enforcement detachment on board to help perform counter-narcotics operations.[16]

Sioux City leads a joint flotilla through the Persian Gulf, June 2022

In May 2022, Sioux City was assigned to the Sixth Fleet, while she was equipped with a surface warfare module. In late May, Sioux City was re-assigned to the Fifth Fleet and assigned to the Combined Task Force (CTF) 153 in the Red Sea.[17]

On 2 October 2022, Sioux City arrived at her homport of Mayport after a five-month deployment, becoming the first LCS to operate in the Baltic Sea, Mediterranean Sea, Red Sea, Gulf of Aden, Northern Arabian Sea, Gulf of Oman, and Persian Gulf.[18]

On 14 August 2023, Sioux City was decommissioned at Naval Station Mayport.[6]
