      <title>Applying Optimization to Marine Corps Decision Making for Repairable Item Lateral Redistribution Policy</title>
      <link>https://trid.trb.org/View/1896402</link>
      <description><![CDATA[The authors demonstrate some of the immediate cost benefits of centrally managing a multi-site inventory of common repairable parts originally managed as separate stocks. First, the authors modify the basic transportation problem to determine the lowest global cost for redistributing parts between the multiple stockage points. The initial solution results in a $3.7 million reduction in purchasing costs. Next, the authors show that by developing a consolidated shipments model, they are able to reduce the cost to fill demand, with available stock, by 20%. The authors also highlight how they determine per unit and consolidated shipment costs, and essential data elements for this type of model. Finally, the authors conduct sensitivity analysis on the model output to show haw a central stock manager can make tradeoff decisions between cost and readiness.]]></description>

      <title>Presidential Helicopter: Program is Meeting Cost Goals but Some Technical and Schedule Risks Remain</title>
      <link>https://trid.trb.org/View/1698004</link>
      <description><![CDATA[The mission of the presidential helicopter fleet is to provide safe, reliable, and timely transportation in support of the President. The Navy plans to acquire a fleet of 23 VH92A helicopters to replace the current Marine Corps fleet which has been in use for more than 40 years. Delivery of production VH92A helicopters is scheduled to begin in April 2021 and be completed in January 2023. The National Defense Authorization Act of 2014 included a provision for the U.S. Government Accountability Office (GAO) to report annually on the acquisition of the VH-92A helicopter. This report, GAO’s sixth related to the provision, examines (1) the extent to which the program is meeting cost goals and (2) performance and schedule challenges that the program has experienced. To conduct this work, GAO compared the Navy’s April 2019 cost estimates for acquiring and maintaining the new helicopters and October 2019 program schedule information to its April 2014 acquisition baseline. GAO reviewed development test results and status reports from the program. GAO also interviewed officials from the program office, Navy test organizations, and the contractor. GAO is not making any recommendations in this report.]]></description>

      <title>Engineering out the noise</title>
      <link>https://trid.trb.org/View/1507772</link>
      <description><![CDATA[The US Navy, through an Office of Naval Research (ONR) lead effort on Noise Induced Hearing Loss (NIHL), is investigating methods and techniques to mitigate hearing loss for the crews and warfighters. Hearing protection is a viable and increasingly popular method of reducing hearing exposure for many ship crew members; however, it has limitations on comfort and low frequency effectiveness. Furthermore, Personal Hearing Protection (PHP) is often used improperly. Proper vessel planning, programmatic changes and advances in noise control engineering can also have significant impacts by inherently reducing noise exposure through ship design and use of noise control treatments. These impacts go beyond hearing loss mitigation since they can improve quality of life onboard vessels and provide enhanced warfighter performance. Such approaches also can be made to work in the lower frequency range where hearing protection is not as effective. This paper describes non-hearing protection methods being implemented to mitigate and control noise within the US Navy and US Marine Corps. These approaches reflect the latest changes to Mil-Std 1474E, Appendix F.]]></description>

      <title>Should the Marine Corps Ban Motorcycles</title>
      <link>https://trid.trb.org/View/913084</link>
      <description><![CDATA[More Marines were killed in fiscal year (FY) 2008 by motorcycles than by insurgent groups in Iraq. Statistically, motorcycles posed a deadlier threat to Marines than did insurgents. To reduce fatalities, the Marine Corps should place a temporary restriction on the use of sport bikes to older, more experienced riders while expanding training and education on motorcycle safety throughout the force.]]></description>

      <title>Modeling Sea-Based Sustainment of Marine Expeditionary Unit (Special Operations Capable) (MEU(SOC)) Operations Ashore</title>
      <link>https://trid.trb.org/View/863633</link>
      <description><![CDATA[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. 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.]]></description>

      <title>Options for Strategic Military Transportation Systems</title>
      <link>https://trid.trb.org/View/761666</link>
      <description><![CDATA[The Administration’s strategy for national defense emphasizes the ability to respond rapidly to military crises wherever they might arise. To that end, the Department of Defense (DoD) is pursuing a variety of initiatives designed to reduce the time necessary to deploy combat forces around the world. Those initiatives include ongoing production of C-17 transport aircraft by the Air Force, development of concepts for the sea basing of military forces by the Navy and Marine Corps, and development of lighter, more easily transportable combat vehicles by the Army as part of its Future Combat Systems program. This Congressional Budget Office (CBO) study—prepared at the request of the Readiness Subcommittee of the House Committee on Armed Services—looks at the technical, operational, and cost issues associated with alternative transportation systems that DoD might develop and procure to reduce the time needed to deploy forces. The study compares the advantages, disadvantages, and costs of six transportation alternatives: four that would use existing technologies and two that would develop more-advanced systems. In keeping with CBO’s mandate to provide objective, impartial analysis, this study makes no recommendations.]]></description>

      <title>IOOS: CONTINUING THE NAVY'S LEGACY OF UNDERSTANDING THE OCEAN ENVIRONMENT</title>
      <link>https://trid.trb.org/View/686557</link>
      <description><![CDATA[In any military engagement, tactical application of environmental knowledge is a force multiplier. This is especially true in the complex and dynamic marine environment. With this in mind, this article underscores the extent to which a network of ocean observations integrated into a global operational database would be a major asset to sea-based military operations such as those conducted by the U.S. Navy and Marine Corps. The focus is on the strategic importance of developing an Integrated Ocean Observing System (IOOS) to support gathering of ocean observational data.]]></description>

      <title>NAVY/MARINE CORPS CFC/HALON EMISSIONS REDUCTION PROJECT--PROSPECTUS</title>
      <link>https://trid.trb.org/View/402496</link>
      <description><![CDATA[Chlorofluorocarbons (used in refrigeration and as cleaning solvents) and halons (used in firefighting) both have the potential for depleting the stratospheric zone. The U.S. Navy and Marine Corps have been using these chemicals to carry out their missions. No acceptable substitutes are available, so far, and restrictions imposed by the Environmental Protection Agency to satisfy the Montreal Protocol could adversely affect their mission capabilities. This article looks at the problem from a management point of view, outlining a five-phased project to reduce the emission of these chemicals to the atmosphere. It sees successful completion of the project as a very positive contribution that can be made by the military to the improvement of the global environment.]]></description>

      <title>FIBERGLASS-REINFORCED RIGID POLYURETHANE EXPEDIENT PAVEMENT SUBJECT TO SIMULATED F-4 AIRCRAFT TRAFFIC</title>
      <link>https://trid.trb.org/View/162363</link>
      <description><![CDATA[A multipurpose expedient paving system is being developed to enable more rapid construction of expeditionary airfields by Marine Corps forces engaged in an amphibious landing. Previous research has resulted in a conceptual pavement, FIBERMAT, which consists of a facing of fiberglass-reinforced polyester resin (FRP) bonded to a core of fiberglass-reinforced rigid polyurethane foam. FIBERMAT has been subjected to a series of laboratory tests to define response to stress fatigue and environmental cycling. A similar structural sandwich of FRP and rigid polyurethane foam has been tested and found to meet F-4 aircraft static load, tailhook impact, and engine exhaust blast requirements. This report documents the results of a traffic test conducted on a section of FIBERMAT having a 5-inch-thick fiberglass-reinforced foam core and a 1/4-inch-thick FRP facing. Distributed traffic was applied to the test section with a load cart which simulated a main gear of an F-4 aircraft. The cart was equipped with a 30-7.7, 18-ply-rating tire inflated to 265 psi and loaded to 27,000 pounds. The first failure within the test section was recorded at 136 coverages (1,306 passes) of the load cart, and the entire test section was considered failed at 310 coverages (2,141 passes).

      <description><![CDATA[The purpose of this investigation was to develop a system to be used in the construction of fiberglass-reinforced plastic surfacings for soil under wet conditions. The effect of water in the substrate and in the fiberglass mat, on laminate properties, has been defined and solutions have been developed for some of the problems. A system of chemical components has been developed for the field placement of the reinforced plastic soil surfacings under wet conditions, that is superior to that presently used and is usable with the basic spray equipment now used by the Marine Corps.]]></description>
