The Marines' Expeditionary Fighting Vehicle (EFV): Background and Issues for Congress


Book Description

The Expeditionary Fighting Vehicle (EFV) is an armored amphibious vehicle program that originated two decades ago to replace the 197Os-era Amphibious Assault Vehicle (AAV). The EFV has experienced a variety of developmental difficulties, resulting in significant program delays and cost growth. While the Marine Corps and Department of Defense remain optimistic about the future of the EFV program, there continue to be major concerns about the EFV's reliability and escalating costs. This report will be updated as conditions warrant.




Materials for Marine Systems and Structures


Book Description

Treatise on Materials Science and Technology, Volume 28: Materials for Marine Systems and Structures provides an integrated approach, utilizing the environmental information of the ocean scientists, materials science, and structural integrity principles as they apply to offshore structures and ships. The book discusses the materials and their performance in marine systems and structures; the marine environment; and marine befouling. The text also describes marine corrosion; corrosion control; metallic materials for marine structures; and concrete marine structures. Materials for mooring systems and fracture control for marine structures are also considered. Professional scientists and engineers, as well as graduate students in the fields of ocean and marine engineering and naval architecture and associated fields will find the book useful.

The Marines' Expeditionary Fighting Vehicle (EFV): Background and Issues for Congress


Book Description

The Expeditionary Fighting Vehicle (EFV) is an armored amphibious vehicle program that originated two decades ago to replace the 1970s-era Amphibious Assault Vehicle (AAV). Like current AAVs, the EFV is designed to roll off a Navy amphibious assault ship, move under its own power to the beach, and cross the beach and operate inland. The EFV has experienced a variety of developmental difficulties, resulting in significant program delays and cost growth. The EFV is currently in its second systems design and development (SDD) phase attempting to improve the EVF's overall poor reliability and performance that it demonstrated during its 2006 operational assessment. If the EFV passes the current SDD in early 2011, it is expected to begin initial production if DOD has not cancelled the program and if it is fully funded.




Materials in Marine Technology


Book Description

Materials in Marine Technology covers the important aspects of metallurgy and materials engineering which must be taken into account when designing for marine environments. The purpose is to aid materials selection and the incorporation of materials data into the design, manufacture and inspection strategy. Recent advances in materials technology, including the use of new materials for marine applications Alloys, Polymers and Composites are examined in detail. The integrated approach is design oriented and is supported by recent case studies.




US Army and Marine Corps MRAPs


Book Description

The Mine Resistant Ambush Protected (MRAP) vehicle is the newest land warfare system in the United States Army and Marine Corps inventory. Designed to meet the challenges of operating in a counterinsurgency environment, the MRAP has taken survivability to a new level. MRAPs are currently manufactured by three companies: BAE Systems, Navistar International Military Group, and Force Protection Inc. Each company manufactures an MRAP according to one of three classifications set by the US Department of Defense: Category I, Category II, or Category III. The Category I MRAPs are designed for urban combat. Category II covers the MRAPs designed for convoy security, medical evacuation, and explosive ordnance disposal. The Category III MRAP performs the same function as Category II but is designed to carry more personnel. Since their introduction in 2007, MRAPs have performed remarkably in the asymmetric warfare environment. Their unique design and survivability characteristics have saved the lives hundreds of soldiers who otherwise would have been lost to landmines or IED attacks. As with any combat system, however, the MRAP is not without its drawbacks.




LAV-25


Book Description

The Light Armored Vehicle 25 (LAV-25) has played a significant role in transforming United States Marine Corps doctrine since its introduction in the early 1980s. The Marine Corps' Light Armored Vehicle program was based on the proven Swiss MOWAG Piranha series of 4x4, 6x6, and 8x8 wheeled vehicles. However, developing organizational units, tactics, and employment of the weapon system within the force structure of the Marine Corps proved to be more of a challenge than fielding the weapon system. This resulted in multiple re-designations for LAV units within the Corps. The LAV first saw combat in Panama during Operation Just Cause and LAV-25s have fought in every major conflict since, including Operation Enduring Freedom, and Operation Iraqi Freedom. This book covers the design, development, and deployment of this continuingly successful vehicle.




Opportunities in Protection Materials Science and Technology for Future Army Applications


Book Description

Armor plays a significant role in the protection of warriors. During the course of history, the introduction of new materials and improvements in the materials already used to construct armor has led to better protection and a reduction in the weight of the armor. But even with such advances in materials, the weight of the armor required to manage threats of ever-increasing destructive capability presents a huge challenge. Opportunities in Protection Materials Science and Technology for Future Army Applications explores the current theoretical and experimental understanding of the key issues surrounding protection materials, identifies the major challenges and technical gaps for developing the future generation of lightweight protection materials, and recommends a path forward for their development. It examines multiscale shockwave energy transfer mechanisms and experimental approaches for their characterization over short timescales, as well as multiscale modeling techniques to predict mechanisms for dissipating energy. The report also considers exemplary threats and design philosophy for the three key applications of armor systems: (1) personnel protection, including body armor and helmets, (2) vehicle armor, and (3) transparent armor. Opportunities in Protection Materials Science and Technology for Future Army Applications recommends that the Department of Defense (DoD) establish a defense initiative for protection materials by design (PMD), with associated funding lines for basic and applied research. The PMD initiative should include a combination of computational, experimental, and materials testing, characterization, and processing research conducted by government, industry, and academia.
