Description
Military Sealift Command operates 19 Large, Medium-Speed, Roll-on/Roll-off Ships, or LMSRs. These ships have significantly expanded the nation's sealift capability in the 21st century. Twenty LMSRs have been converted or built at U.S. shipyards. One was further converted for other use. Eight are assigned to MSC's Prepositioning Program and the remaining 11 belong to MSC's Sealift Program.

Features
LMSRs can carry an entire U.S. Army Task Force, including 58 tanks, 48 other tracked vehicles, plus more than 900 trucks and other wheeled vehicles. The ships can carry vehicles and equipment to support humanitarian missions, as well as combat missions. The new construction vessels have a cargo carrying capacity of more than 380,000 square feet, equivalent to almost eight football fields. In addition, LMSRs have a slewing stern ramp and a removable ramp that services two side ports making it easy to drive vehicles on and off the ship. Interior ramps between decks ease traffic flow once cargo is loaded aboard ship. Two 110-ton single-pedestal twin cranes make it possible to load and unload cargo where shoreside infrastructure is limited or nonexistent. A commercial helicopter deck was added for emergency, daytime landing.

Background
The need for additional military sealift ships was identified in a congressionally mandated study by the Joint Chiefs of Staff in the early 1990s. It highlighted the urgent need for greater sealift capacity to transport military equipment and supplies during wartime and other national contingencies. An ambitious Strategic Sealift Acquisition Program added 19 LMSRs, providing five million square feet of new capacity: two million for Prepositioning and three million for surge sealift. Subsequently, one surge LMSR, USNS Soderman, was transferred to MSC's Prepositioning Program for conversion as the Maritime Prepositioning Force (Enhanced) ship USNS Lance Cpl. Roy M. Wheat. Congress then authorized the construction of a new replacement LMSR to be named USNS Soderman.
