Mobile Landing Platform - MLP

The Mobile Landing Platform (MLP) is a highly flexible ship that provides logistics movement from sea to shore supporting a broad range of military operations. The MLP ship class leverages an existing commercial design, the Alaska class crude oil carrier built by General Dynamics'- National Steel and Shipbuilding Company (NASSCO), to ensure design stability and low development costs. These ships will operate within Maritime Prepositioning Ship Squadrons as mobile sea bases providing the U.S. Navy Fleet with a critical access infrastructure that supports the flexible deployment of forces and supplies.

MLP 1 and MLP 2 possesses add-on modules that support a vehicle staging area, vehicle transfer ramp, large mooring fenders and up to three LCAC vessel lanes to support its core requirements. With a 9,500 nautical mile range at a sustained speed of 15 knots these approximatley 80,000 ton, 785-foot ships leverage float-on/float-off technology and a reconfigurable mission deck to maximize capability. Additionally, the ships' size allows for 25,000 square feet of vehicle and equipment stowage space and 380,000 gallons of JP-5 fuel storage.

MLP-3 will serve as the first purpose built Afloat Forward Staging Base (AFSB) variant, optimized to support a variety of maritime based missions. The design of MLP 3 and MLP 4 adds a flight deck, berthing, fuel storage, equipment storage and repair spaces.

The MLP class is operated by Military Sealift Command personnel.
Since 2005, the Navy has conducted a series of at-sea exercises demonstrating the ability to transfer vehicles between a surrogate Mobile Landing Platform (MLP) ship and a Large Medium-Speed Roll-on/Roll-off (LMSR) ship. In 2010, using the surrogate MLP, M/V Mighty Servant 3, personnel and vehicles (wheeled and tracked) were successfully transferred to the USNS Soderman through employment of a new motion compensating vehicle transfer ramp specifically designed by the Navy for this purpose. The ships were able to successfully demonstrate transfer ability in high sea state three and low sea state four conditions.

The Navy worked in close partnership with NASSCO to identify cost savings early in the MLP design process while pursuing a concurrent design and production engineering approach. Following the successful production readiness review - an evaluation of the ship's design maturity, availability of materials, and the shipbuilder's ability to successfully start construction - the Secretary of the Navy certified the design and informed Congress that the design of MLP was more than 85 percent complete and ready to proceed with fabrication.

On May 27, 2011, the Navy awarded NASSCO a fixed-price incentive fee type contract for the detail design and construction of MLP 1 and MLP 2. A detail design and construction contract was subsequently awarded for MLP 3 on February 26, 2012.

USNS Montford Point (MLP 1) delivered on time and on budget in May 2013 and successfully completed Final Contract Trials with the Board of Inspection and Survey (INSURV) report stating that, “functional area scores were among the highest observed for any ship.” MLP 1 had CCS insstalled on April 20, 2014. USNS John Glenn (MLP 2) delivered in March 2014 and is currently having the CCS installed. MLP 3 had its keel laid on November 5, 2013, and is scheduled to launch in November 2014.
