Mobile Landing Platform The Mobile Landing Platform is a class of United States Navy auxiliary ships conceived to provide a flexible afloat logistics and staging capability for United States Marine Corps expeditionary operations, United States Indo-Pacific Command contingency response, and cooperation with allies including Royal Navy, Japan Maritime Self-Defense Force, and Royal Australian Navy. Designed to bridge maritime logistics between strategic sealift such as Military Sealift Command and littoral forces like Marine Expeditionary Unit, the concept emerged from lessons of Operation Iraqi Freedom, Hurricane Katrina, and evolving concepts such as Sea Basing and Distributed Operations. The hull form and modular deck enable embarkation of vehicles, landing craft, and aviation assets to support operations with partners including NATO, United Nations, and regional navies.
The design emphasizes a long, unobstructed flight and vehicle deck derived from commercial RO-RO and container ship architecture; specifications include a length comparable to large auxiliary ships and heavy-lift vessels used by Military Sealift Command and Maersk Line. The platform incorporates a large well deck and a floodable ramp to operate Landing Craft Air Cushion (LCAC), conventional landing craft, and other amphibious connectors similar to those used by Amphibious Ready Group ships. To support aviation, the aft and amidships decks provide spots and clearances for MV-22 Osprey, CH-53 Sea Stallion, and unmanned systems comparable to those operating from USS America (LHA-6). Propulsion and hotel systems draw on designs used in commercial cruise ship and roll-on/roll-off propulsion plants employed by contractors such as Newport News Shipbuilding and Ingalls Shipbuilding. Survivability measures reflect auxiliary standards outlined by Naval Sea Systems Command and interoperability with United States Coast Guard and Defense Logistics Agency.
The MLP concept traces to programmatic studies within United States Central Command and Marine Corps Combat Development Command during the 2000s, influenced by operational demands from Operation Enduring Freedom and Operation Iraqi Freedom. Procurement moved through competitive design and construction solicitations managed by Military Sealift Command and Office of the Secretary of Defense, with contracts awarded to NASSCO (a division of General Dynamics). Budgetary oversight involved United States Congress committees including the House Armed Services Committee and Senate Armed Services Committee, and cost and schedule considerations referenced doctrine from Joint Chiefs of Staff publications. Program adjustments produced role expansions into afloat forward staging baseline concepts championed by leaders within United States Fleet Forces Command.
In doctrine, MLPs serve as afloat hubs enabling Power projection operations, logistics throughput, and humanitarian assistance missions alongside organizations such as United States Agency for International Development and International Committee of the Red Cross. They operate within task forces under commanders of United States Pacific Fleet or United States European Command and integrate with carrier strike groups and amphibious ready groups drawn from II Marine Expeditionary Force and III Marine Expeditionary Force. Employment concepts include supporting Expeditionary Advanced Base Operations, distributed logistics for Littoral Combat Ship tasking, and acting as mother ships for unmanned surface and undersea vehicles developed in collaboration with Office of Naval Research. Training and doctrine updates have been coordinated with Naval Surface Warfare Center and multinational exercises such as RIMPAC.
The original MLP design evolved into multiple variants, including the Afloat Forward Staging Base (AFSB) and the Maritime Prepositioning variations, aligning with precedents set by ships like USS Ponce (AFSB(I)-15). The AFSB variant emphasizes berthing and command facilities to support special operations and mine countermeasure forces linked to Naval Special Warfare Command and Explosive Ordnance Disposal units. Other conceptual classes extend mission modules to support aviation operations, humanitarian platforms used by United Nations Office for the Coordination of Humanitarian Affairs, and logistics connectors for SOUTHCOM and CENTCOM theaters. Classification and hull numbering were managed under Military Sealift Command’s ship registries.
Construction used commercial shipbuilding techniques at NASSCO yards, adapting commercial tanker and bulk carrier production lines to military outfitting standards including reinforced deck structures and modular electrical systems as practiced by Huntington Ingalls Industries. Conversions for AFSB roles included installation of command-and-control suites interoperable with Northrop Grumman and Raytheon communication systems, expanded berthing adapted from standards used on San Antonio-class amphibious transport dock ships, and mission bay reconfiguration to support LCAC staging. Workpacks were phased to accommodate lifecycle maintenance in naval shipyards such as Norfolk Naval Shipyard and contractor facilities.
MLP-class and derivative AFSB ships have been forward-deployed to support operations in the Indo-Pacific and U.S. Central Command areas of responsibility, participating in exercises like Operation Dawn Blitz and Vigilant Guard, and providing platform support for humanitarian responses following storms like Typhoon Haiyan regionally. They have been employed in cooperative deployments with Royal Netherlands Navy and Japan Self-Defense Forces during multinational amphibious exercises, and served as staging bases for mine countermeasure efforts alongside HMCS Chicoutimi-style vessels and allied logistics ships.
Several allied navies explored similar concepts inspired by MLP capabilities, drawing comparisons with Royal Navy auxiliary designs, Royal Australian Navy's amphibious ships such as HMAS Canberra (L02), and French Navy multi-role vessels like Mistral-class amphibious assault ship. Defense firms across Europe and Asia offered modular logistics platforms to partners including India, South Korea, and Saudi Arabia as alternatives to the US concept, often citing interoperability with NATO standards and multinational exercises.
