Encyclopedia
The 31 Maritime Prepositioning Ships (MPS) are part of the United States Military Sealift Command
's (MSC) Prepositioning Program. They are strategically positioned around the globe to support the Army, Navy, Air Force, Marine Corps and Defense Logistics Agency. Most are named after Medal of Honor
recipients from the service they are intended to support from various wars.
The MPS ships are assigned to three Maritime Prepositioning Ship squadrons located in the Mediterranean, the Indian Ocean at Diego Garcia
and the Western Pacific at Guam
and Saipan
. The MPS ships in each squadron have sufficient equipment, supplies and ammunition to support a Marine Corps Air Ground Task Force for 30 days. The MPS ships are self-sustaining, having cranes which enable them to unload their own cargo at sea or pierside.
The first two ship classes used for the MPS role (the Corporal Louis J. Hauge, Jr. and Sergeant Matej Kocak classes) were chartered by MSC from civilian shipping lines and converted for the role. Later ships were purpose-built.
