Maritime prepositioning ship

Strategic sealift ships are part of the United States Military Sealift Command's (MSC) prepositioning program. There are currently 17 ships in the program, strategically positioned around the world 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 support. The ships are assigned to two Military Prepositioning Ship (MPS) squadrons located in the Indian Ocean at Diego Garcia and in the Western Pacific Ocean at Guam and Saipan.

The MPS ships in each squadron have sufficient equipment, supplies and ammunition to support a Marine Air-Ground Task Force for 30 days. The MPS ships are self-sustaining, with cranes to unload at sea or pierside. MSC chartered the first two ship classes in the MPS role (the ''Corporal Louis J. Hauge Jr.'' and ''Sergeant Matej Kocak'' classes) from civilian shipping lines and converted them. Later ships were purpose-built.

Ships

''Sergeant Matej Kocak'' class

The ''Sergeant Matej Kocak'' class, the second class of MPS ships chartered by MSC, also gained amidships and a helicopter deck after conversion. These ships, delivered to MSC in the mid-1980s, built at Sun Shipbuilding & Drydock Co., Chester, Pennsylvania, and converted at National Steel and Shipbuilding Company, San Diego. They were previously owned by Waterman Steamship Corporation but recently sold to MSC and now operated by Keystone Shipping Company. They were all part of the Waterman Line C7-S-133a Series.
