Maritime Prepositioning Ships - T-AK, T-AKR and T-AOT

 
Description
The Navy's 14 Maritime Prepositioning Ships (MPS) are part of Military Sealift Command's Prepositioning Program. These ships preposition U.S. Marine Corps vehicles, equipment and ammunition throughout the world.
 
Features
The MPS 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 Expeditionary Brigade of about 17,000 personnel for 30 days. The MPS ships are self-sustaining, having cranes which enable them to unload their own cargo. Beginning in 2000 with the delivery of USNS 1st Lt. Harry L. Martin, three additional ships were added to the Maritime Prepositioning Force, adding the capacity to carry expeditionary airfields, Seabee construction equipment and field hospital cargo.
 
Background
The Sgt. Matej Kocak-class was converted before entering service with MSC. The ships gained 157 feet amidships and a helicopter landing platform after conversion. These ships, delivered to MSC in the mid-1980s, are National Steel and Shipbuilding, San Diego, conversion ships owned and operated by Waterman Steamship Corp.

USNS 2nd Lt. John P. Bobo-class ships are new construction ships delivered to MSC in the mid-1980s from General Dynamics, Quincy, Mass. In January 2006, MSC purchased MV 1st Lt. Jack Lummus, MV 1st Lt. Baldomero Lopez and MV Pfc. Dewayne T. Williams. MV 2nd Lt. John P. Bobo was purchased in January 2007. SS Sgt. Matej Kocak, SS Maj. Stephen W. Pless and MC Sgt. William R. Button were purchased January 2009.

USNS 1st Lt. Harry L. Martin was modified in 1999 and delivered to MSC in 2000.

USNS Gunnery Sgt. Fred W. Stockham (ex-Soderman) was modified in 2000 and delivered to MSC in 2001.

USNS Lance Cpl. Roy M. Wheat began modifications in 1999, including a 118-foot mid-body insertion plug and was delivered to MSC in 2003.

USNS Dahl, a large, medium, speed, roll-on/roll-off ship, moved into the Maritime Prepositioning Ships fleet April 1, 2009, from another part of the Prepositioning Program.

Government-owned tanker USNS Lawrence H. Gianella began serving the Prepositioning Program July 1, 2009. It was formerly in Military Sealift Command's Sealift Program.
