Operational Maneuver From the Sea (OMFTS) and its implementing concept, Sea Based Logistics (SBL), stress the need for logistically supporting forces ashore directly from a sea base. This study analyzes the capability of a current LHD-class amphibious ship to sustain a force deployed ashore through direct ship-to-objective movement of sustainment requirements. This study presents a baseline simulation model to estimate the ability of a LHD to deliver the required logistic support. Experiments were conducted with various scenarios and distances between the deployed forces and the nominal Sea Base (LHD). Sensitivity analysis was conducted to determine the effects of various parameters on the ability of the Sea Base to successfully accomplish the given scenarios with the specified conditions. Results indicate a substantial increase in the number of aircraft, operational availability of those aircraft, and/or a substantial reduction in sustainment requirements are needed in order to successfully accomplish the stated scenarios of this study. The results of this study could support the design of future LHD-class ships.
Approved for public release; distribution is unlimited; Operational Maneuver From the Sea (OMFTS) is a new Concept under development by the Marine Corps. OMFTS is a warfighting concept that revises the way combat power is projected in littoral regions in that it uses the sea as a maneuver space and safe haven for logistics, while further adopting ship to objective operations. Sea-Based Logistics (SBL) uses the Amphibious Ready Group (ARG) ships to provide a sea-base from which combat forces ashore are directly sustained. To function in this new capacity, the ARG units need replenishment to maintain high stockage levels of fuel, ammunition, and stores. This thesis develops a computer simulation for modeling the logistical support needed for ARG units functioning in a sea-base role for supporting OMFTS
Approved for public release; distribution is unlimited; The U.S. Marine Corps concept for the projection of naval power ashore is Operational Maneuver From the Sea (OMFTS). OMFTS calls for movement of Marines from ships at sea directly to objectives deep inland without requiring a pause to build up combat power on the beach. Support for ground forces is expected to come from the sea, and be delivered primarily by air. This demands that sea based logistics assets remain sufficiently close to shore to allow air assets to conduct resupply operations directly to the battlefield. The implication of this is that Navy ships may sacrifice operational and perhaps tactical mobility while sustaining the Marine operation. This thesis determines the distance from the coastline sea based Combat Service Support (CSS) assets will be able to maintain and still support operations of a given magnitude, and how tactically constrained Navy ships will be in order to support this concept of expeditionary warfare. It focuses on the time distance weight/volume relationships involved, and takes into account characteristics of the resupply assets, such as aircraft availability, capacity, method of employment, and the effects of combat attrition. Three methods of employing a Marine Expeditionary Unit are studied...

This thesis documents a simulation model developed to assist in the planning of Operational Test and Evaluation (OTandE) of the Marine Corpsgas Advanced Amphibious Assault Vehicle (AAAV). The model simulates a platoon of AAAVs in an amphibious assault, using Operational Maneuver From the Sea (OMFTS) techniques, supported by elements of a Marine Expeditionary Unit (MEU) aboard amphibious ships offshore. The emphasis of the model is on suitability issues, specifically operational availability, maintainability, and supportability. In particular the effect of logistical support for one AAAV on the ability of the platoon to complete a mission. The purpose of the simulation is to gain insight into important and highly sensitive factors that, when changed slightly, have large effects on the platoon of AAAVgass ability to perform its mission. The results of the model show that, the assumed form of the distribution of failure times for a single AAAV is the most important aspect of reliability test data. Simply calculating the mean time to failure (MTTF) from data and using an exponential model is inadequate. Even if an observed or estimated MTTF is within an acceptable requirement threshold level, if it is characterized by a high or even moderate number of infant failure times...

Operational Maneuver From the Sea (OMFTS) and its implementing concept, Sea Based Logistics (SBL) stress the need for logistically supporting forces ashore directly from a sea base. This implies a radically different approach for supporting forces ashore in the future. This study analyzes the concept of SBL in the area of inter-ship and intra-ship movement of materiel as well as ship-to-objective materiel movement in order to gain insight into the envisioned SBL support concept. This study presents a conceptual model blending aspects of current underway replenishment (UNREP) processes with an operational scenario incorporating the tenets of the OMFTS and SBL concepts. A baseline simulation model was developed to estimate UNREP cycle times under various scenarios. Experiments were conducted by modifying the baseline model to assess the impact on inter/intra ship materiel movement cycle time by increasing the lift capacity of the helicopters used for vertical replenishment (VERTREP) as well as increasing the number helicopters used for VERTREP. Results indicate that an increase in helicopter lift capacity significantly reduce overall cycle time, more importantly UNREP cycle time. The simulation model identifies constraining resources (i.e....
The United States Marine Corps Advanced Amphibious Assault Vehicle Personnel Variant (AAAV-P) is a critical weapon system that supports the Naval Operational Maneuver from the Sea (OMFTS) concept. The AAAV-P will provide the Marine Corps with the ability to project naval power ashore in support of strategic objectives. The Marine Corps is relying on the AAAV-P to exploit the sea and land terrain in order to attain surprise and be able to rapidly take advantage of weak points in enemy littoral defenses. The first prototype of the AAAV-P will be completed in June 1999. Successful operation of the AAAV-P is heavily dependent upon the Vetronics System communications network residing within the vehicle. The Vetronics System supports three networks: a High Speed Data Bus, a Utility Bus, and a Powertrain Bus. This thesis develops a model of the High Speed Data Bus, which is considered the main data bus within the AAAV- P. The simulation results of the model are analyzed to determine if the High Speed Data Bus is properly designed to handle the anticipated communications traffic that will traverse the network. The network performance capability is evaluated under various scenarios.

Approved for public release; distribution is unlimited; Despite the apparent abundance of modern communication technology such as satellites, computers, and fiber-optic transmission systems, communication capacity is a limited resource for littoral operations. The Navy and Marine Corps lack the dedicated networks to support such doctrinal concepts as Operational Maneuver From the Sea (OMFTS). One solution is to develop a Littoral Region Area Network (LRAN). The primary goal of this thesis is to underscore the littoral operating environment and bandwidth requirements. It also investigates reliable seaborne network communication systems complementary to satellite and wireless networks, and proposes an open, standards-based modular architecture, utilizing a network centric design model as the basis for LRAN. It employs modeling and simulation techniques to demonstrate coupling of the system integration processes with the doctrinal concepts of OMFTS

agency.; The Marine Corps sees Operational Maneuver From The Sea (OMFTS) and Ship To Objective Maneuver
(STOM) as the way they would like to fight in the future. Sea-Based Logistics (SBL) is a key supporting capability. This report reviews studies of the feasibility of sea-basing logistics functions in OMFTS and STOM, and identifies a number of issues which relate to the viability of SBL. As a recent and relevant example of OMFTS, the 1982 Falklands War is examined for the lessons it offers for the viability of SBL.
The United States Marine Corps concept for the projection of naval power ashore is Operational Maneuver From the Sea (OMFTS). In order to carry out the concept in OMFTS, the Marine Expeditionary Unit is a force to project power. To ensure the MEU is successful it requires logistics support back to the sources of supply. The objective of this thesis is to introduce the current methods of supporting the MEU and to provide recommendations for improvements. It focuses on the support organizations, Traffic Management Office (TMO), Deployed Support Unit (DSU), MEU Service Support Group (MSSG), Preservation, Packing, Packaging (PP&P), and the expeditor concept. The thesis also examines the existing technology in the Global Transportation Network (GTN) using In- Transit Visibility (ITV) to track shipments.
The Marine Corps has embraced the concepts of Operational Maneuver From The Sea (OMFTS) and Ship-to-Objective Maneuver (STOM) as the next progression in the evolution of amphibious warfare. These related concepts envision harnessing emerging technologies to allow the projection of naval power ashore faster and from greater distances than in the past. Additionally, both concepts identify the ability to conduct sea-based logistics (SBL) as a key requirement for successful implementation. Sea-based logistics involves executing a wide range of logistical functions from a sea-base rather than from sites traditionally established ashore. Acknowledged enhancements are required to realize a complete SBL capability; however, the ability to provide some measure of sea-based sustainment exists today. This thesis models the sea-based sustainment of Marine Expeditionary Unit (Special Operations Capable) (MEU(SOC)) forces deployed from Amphibious Ready Group (ARG) ships. Missions are developed for analysis; each is coupled with an appropriate force package of personnel and equipment density. Sustainment requirements and available transportation capacities are then determined and compared for each mission. This comparison along with several excursions provides insight into the nature of sea-based sustainment feasibility. It also gauges potential limitations for sea-based sustainment.
The Marine Corps has formed a vision of how to conduct future amphibious warfare through its development of Operational Maneuver From the Sea (OMFTS), Ship-to-Objective Maneuver (STOM), and Sea-based Logistics (SBL) concepts. These concepts have forces deploying directly from ship to objectives ashore with a reduction or elimination of logistics infrastructure ashore. Combat forces operating ashore will be sustained directly from a sea-base with support from ship-to-shore transporters. By sea basing logistics functions, there will be a much greater demand upon these transporters. This thesis models the sea-based sustainment of Marine Expeditionary Brigade (MEB) forces deployed from amphibious warfare ships. A scenario for analysis is developed with force packages of personnel and equipment located at certain locations ashore during different days of an operation. Sustainment requirements and available transporter capacity are then determined and compared for twenty-seven cases comprising different ship-to-shore distances, different levels of aircraft attrition due to enemy interdiction, and different footprints of mobile logistics forces deployed ashore. This comparison provides insight into the ability of SBL to sustain forces ashore conducting rations in accordance with OMFTS and STOM concepts.

Approved for public release; distribution is unlimited; In 2005, the Broad Agency Announcement (BAA) #05-020 called for research and development efforts to design the Transformable Craft (T-Craft), a transport craft that will create a "game-changing" capability for the U.S. Navy's Seabasing concept. The TCraft is intended to advance the concepts of Operational Maneuver from the Sea (OMFTS) and Ship-to-Objective Maneuver (STOM). In this thesis, we examine various T-Craft operational and performance requirements using discrete event simulation modeling, statistical design of experiments, and robust analysis techniques. The model is used to investigate the rates at which the T-Craft/Sea base system, as specified in BAA #05-020, can deliver materiel to shore. We use robust analysis to evaluate the impact of both operational and performance design choices for the T-Craft across a spectrum of conflict conditions. The result is a set of design and policy recommendations that are targeted toward achieving mission success in a broad variety of used scenarios.; Outstanding Thesis; German Army author
Changes in the global situation resulting from the demise of the Soviet Union have led to major restructuring in United States' military. As a result the Navy and Marine Corps have reevaluated amphibious concepts, resulting in Operational Maneuver From the Sea (OMFTS), and Sea Based Logistics (SBL). OMFTS supposed by SBL rely on a "sea-base" to act as the staging area for the dissemination of supplies to the amphibious units ashore. This close integration of Navy and Marine Corps logistics requires Naval Officers and Marine Corps Officers be aware of each other's requirements. Current training aids do not model OMFTS and SBL To facilitate training a modular computer-based wargame called NAVLOGS has been developed with the logistics concerns of OMFTS and SBL in mind. The core classes of NAVLOGS include the Scenario Builder, the Coastline Model, and a Map Scale Generator. These core classes enable the user to create scenarios for NAVLOGS with little or no programming skill thus taking scenario design from the programmers and giving it to the end user.; U.S. Navy (U.S.N.) author.
Approved for public release; distribution is unlimited; The United States Marine Corps is exploring the concepts of Operational Maneuver From the Sea (OMFTS) and Ship-To-Objective Maneuver (STOM) as methods for employment of maritime forces in the future. At the same time, the Department of Defense (DoD) is pursuing the acquisition of the Joint Tactical Radio System (JTRS), a multi-band, multi-channel, multi-mode family of radios, designed to form self-organizing, self-healing communications networks. The JTRS will have to support Marine forces in combat at long distances from the forces' support and higher headquarters units. This extended range will require the use of relay radios in order to maintain connectivity between the attacking force and its support. This thesis explores the relay station bandwidth requirements to support Marine forces. The question is analyzed through the use of a discrete-event simulation written in Java, which models the behavior of a JTRS network in a STOM scenario. Quality of service of the communication network is measured by timely delivery of messages. The results of the simulation indicate that the JTRS network performance is insensitive to relay station bandwidth. Rather, the subordinate headquarters involved in the scenario were the most overloaded nodes in the network; http://www.archive.org/details/simulationofjoin00turn; Major...
Operational Maneuver From the Sea (OMFTS) is a Marine Corps concept that shifts the emphasis from blue-water superiority to power projection in the littorals. OMFTS treats the sea as maneuver space, and moves forces directly from ship to objectives ashore with little or no prior build-up of supplies ashore. This thesis develops the Sea-Based Logistic Optimization Model (SBLOM), an integer programming model that assesses the feasibility of conducting sea- based logistics in an OMFTS scenario based on capabilities of current and future assets, e.g., the Landing Craft Air Cushion and the MV-22 Osprey aircraft. SBLOM minimizes (when feasible) the initial fuel requirement of the Marine Expeditionary Unit (Special Operations Capable) (MEU(SOC)) ashore, and develops a fuel-delivery schedule from the sea using the lift assets available on a group of three or four ships known as an Amphibious Readiness Group (ARG). Using two OMFTS scenarios, SBLOM is run with the ARG at stand-off distances of 50, 70, and 100 nautical miles. The scenarios involve a humanitarian mission and an amphibious raid. In all cases, the use of sea-based logistics is feasible: An optimal delivery schedule is developed that meets the daily fuel requirements of the MEU(SOC) and maintains sufficient fuel levels the throughout the mission's duration.; U.S. Navy (U.S.N.) author.
Extending the littoral battlespace (ELB) is vital to the United States Navy and Marine Corps. Fast, accurate, and reliable fire support will continue to be essential to the execution of Operational Maneuver From The Sea (OMFTS) and Ship To Objective Maneuver (STOM). The emergence of new technology has made these concepts possible. Technology will allow Marines to reach their objectives faster and farther then ever before. Information gathering, dissemination, and targeting will be key factors to the success of these new concepts. The development of low earth orbiting satellites that provide a seamless command, control, communications and intelligence (C4I) network will be necessary for ELB. This network will provide worldwide coverage, emphasize light forces with the ability to connect to larger forces and have a near zero footprint. The emerging communication architectures must have the capacity for voice, data, and video handling from high to narrow bandwidth. Developing a light communications architecture that supports these emerging concepts will allow ELB to be responsive for joint operations in the twenty-first century.; U.S. Marine Corps (U.S.M.C.) authors.
Approved for public release; distribution is unlimited.; As the United States enters a new millennium, the armed forces, and in particular the Marine Corps, face new challenges in the manner that they deploy and operate. Reductions in both personnel and naval shipping, coupled with an ever-changing world political environment, have led to a dramatic shift in the way that the United States must project its power. As recent combat operations in Afghanistan have demonstrated, there is a valid requirement for forces to possess the ability to operate from the sea directly to an objective area with minimal or no amphibious landing support. This thesis provides an analysis of the most advantageous assault support aircraft allocation aboard a Marine Expeditionary Unit (MEU) in operations such as this. With the MEU tasked as one of the prominent fixtures in the timely projection of power ashore for the United States, the capabilities (or lack thereof) of assault support aircraft become increasingly important as ship-to-objective distances increase. Our method of finding an optimal composition of aircraft consists of constructing an Assault Support Optimization Model (ASOM). ASOM is assists us in prescribing an ideal configuration of assault support aircraft while emulating the dynamic amphibious environment. ASOM analyzes the assignment of several aircraft combinations (4 CH-53E/12 MV-22...
