Strategic sealift ships are part of the United States Military Sealift Command's (MSC) prepositioning program. There are currently 49[1][2] ships in the program, 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 support.[2][3][4] The ships are assigned to two[5] Military Prepositioning Ship (MPS) squadrons[6] located in the Indian Ocean at Diego Garcia and 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.


Sergeant Matej Kocak class

PFC. Eugene A. Obregon

The Sergeant Matej Kocak Class, the second class of MPS ships chartered by MSC, also gained 157 feet (48 m) 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 Co.

2nd Lieutenant John P. Bobo class

The 2nd Lieutenant John P. Bobo class ships are new construction ships delivered to MSC in the mid-1980s from General Dynamics Quincy Shipbuilding Division, Quincy, Mass. They were owned by American Overseas Marine (AMSEA) but have been recently sold to MSC and are now operated by Crowley Technical Management.

Former ships

Corporal Louis J. Hauge Jr. class

Named for Medal of Honor recipient Louis J. Hauge Jr. USMC, the Corporal Louis J. Hauge Jr. class is the original class of MPS ships chartered by Military Sealift Command. The five ships are Maersk Line ships converted by Bethlehem Steel. During conversion, the ships gained an additional 157 feet (48 m) amidships and a helicopter landing pad, among other things. They have since been returned to Maersk for commercial use and are no longer part of the MPS program.
