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. |
