MCS-12 Inchon
Mine Countermeasures Support Ship

Operations Desert Shield and Desert Storm identified the need for a dedicated command, control and support ship to support mine countermeasures operations. The contract to convert Inchon was awarded in November 1994 to Ingalls Shipbuilding, Inc., Pascagoula, Miss. USS Inchon was converted from an amphibious assault ship with major changes made to the Command, Control, Communications, Computers and Intelligence (C4I) system including upgrades to the close-in weapons system (Phalanx) and various radars. The ship supports an embarked composite helicopter squadron of eight CH-53E and two SAR/spotter helicopters, and provides alongside support and services for up to four MCM/MHC ships. It can support and accommodate four Explosive Ordnance Disposal (EOD) groups with assigned equipment. Additionally it provides C4I facilities for the MCM group commander. New repair facilities and upgrades to older one were also added, giving the MSC 12 the ability to accomplish whatever repairs are necessary to weapons, LCACs, aircraft, etc., in any theater of operation.
