USSSioux City (LCS-11) was aFreedom-classlittoral combat ship of theUnited States Navy. She is the first ship named afterSioux City, the fourth-largest city inIowa.[9][10]
In 2002, the Navy initiated a program to develop the first of a fleet oflittoral combat ships.[11] The Navy initially ordered two monohull ships fromLockheed Martin, which became known as theFreedom-class littoral combat ships after the first ship of the class,USS Freedom.[11][12] Odd-numbered littoral combat ships are built using theFreedom-class monohull design, while even-numbered ships are based on a competing design, thetrimaran hullIndependence-class littoral combat ship fromGeneral Dynamics.[11] The initial order of littoral combat ships involved a total of four ships, including two of theFreedom-class design.[11]Sioux City was the sixthFreedom-class littoral combat ship to be built.
Sioux City includes additional stability improvements over the originalFreedom 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 thatFreedom had on her first deployment.[14]
The ceremonial “laying of the keel” was on 19 February 2014, atMarinette, Wisconsin.[2][15] The ship was constructed byFincantieri Marinette Marine and launched on 30 January 2016 after beingchristened by hersponsor Mary Winnefield, wife of AdmiralJames A. Winnefeld Jr., USN.[3][16]
Sioux City was delivered to the Navy byLockheed Martin and theMarinette Marine shipyard on 22 August 2018 along with sister shipWichita in a double delivery.[4] The ship wascommissioned at theUnited States Naval Academy inAnnapolis, Maryland on 17 November 2018,[5] and thenassigned toLittoral Combat Ship Squadron Two.
In September 2020,Sioux City was assigned to theUS Southern Command with aUnited States Coast Guard law enforcement detachment on board to help perform counter-narcotics operations.[17]
In May 2022,Sioux City was assigned to theSixth 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 theRed Sea.[18]
On 2 October 2022,Sioux City arrived at her homeport ofMayport after a five-month deployment, becoming the firstLCS to operate in the Baltic Sea, Mediterranean Sea, Red Sea, Gulf of Aden, Northern Arabian Sea, Gulf of Oman, andPersian Gulf.[19]
On 14 August 2023,Sioux City wasdecommissioned at Naval Station Mayport with her final Commanding Officer, Commander Michael Gossett, presiding over the ceremony and placed into a Foreign Military Sale (FMS) disposition status.[6]
