Download or read book Advanced Technology for Naval Gun Tubes written by NATIONAL MATERIALS ADVISORY BOARD (NAS-NAE) WASHINGTON DC. and published by . This book was released on 1971 with total page 82 pages. Available in PDF, EPUB and Kindle. Book excerpt: The object of the study was to recommend long-range improvements in the manufacture and concept of gun barrels, as well as to suggest solutions to current gun manufacturing problems. Improved steels are listed and coatings for the bore proposed, which might result in better performance or lower cost. Alternate metalworking and casting methods are discussed. The manufacture and inspection of barrels are described and some advanced technology proposed. A limited number of advanced concepts for launching projectiles were examined. Of the conclusions reached, the foremost two are the need for better understanding of the interrelationships among the factors responsible for the degradation of gun barrels during service, and the need for the consideration of a barrel as part of an ammunition-propellant-gun system and not as an isolated entity.

Available in PDF, EPUB and Kindle. Book excerpt: Advanced energetic materialsâ€"explosive fill and propellantsâ€"are a critical technology for national security. While several new promising concepts and formulations have emerged in recent years, the Department of Defense is concerned about the nation's ability to maintain and improve the knowledge base in this area. To assist in addressing these concerns, two offices within DOD asked the NRC to investigate and assess the scope and health of the U.S. R&D efforts in energetic materials. This report provides that assessment. It presents several findings about the current R&D effort and recommendations aimed at improving U.S. capabilities in developing new energetic materials technology. This study reviewed U.S. research and development in advanced energetics being conducted by DoD, the DoE national laboratories, industries, and academia, from a list provided by the sponsors. It also: (a) reviewed papers and technology assessments of non-U.S. work in advanced energetics, assessed important parameters, such as validity, viability, and the likelihood that each of these materials can be produced in quantity; (b) identified barriers to scale-up and production, and suggested technical approaches for addressing potential problems; and (c) suggested specific opportunities, strategies, and priorities for government sponsorship of technologies and manufacturing process development.

Download or read book A Sailor s History of the U S Navy written by Thomas J Cutler and published by Naval Institute Press. This book was released on 2005-01-15 with total page 302 pages. Available in PDF, EPUB and Kindle. Book excerpt: Today's sailors have too little appreciation of their heritage. To counter this problem, Thomas J. Cutler has compiled a history of our naval heritage in the form of A Sailor's History of the U.S. Navy. The work is unique in two important ways. First, it is written thematically rather than chronologically. This allows recent history to be blended with more distant (but important) events in ways that will reinforce the timelessness as well as the timeliness of the U.S. Navy, thereby having a greater appeal to today's sailor. There are a number of themes being used—the most obvious are manifested in chapters with the themes of "honor," "courage," and "commitment," but others serve as useful vehicles as well; for example, there is a chapter called "What's in a Name?" that briefly discusses how ships have been/are named and then uses the many ships that have carried the name ""Enterprise"" as the theme for presenting significant portions of the Navy's history. The other unique characteristic of this history is that it focuses wherever possible on the roles of ALL sailors rather than just the officers. That is not to say that Jones and Decatur are not there, but that the emphasis is along the lines of "the crew of the Bon Homme Richard fought on into the night..." rather than "Jones fought..." Also, there are plenty of individual sailor heroes who can stand alongside the Perrys and the Farraguts (Boatswain's Mate First Class Williams who won the Medal of Honor in Vietnam, Dorie Miller of Pearl Harbor fame, Gunner's Mate Third Class Paul Henry Carr at the battle off Samar, etc.). Some emphasis upon what it was like to be a sailor (working and living conditions) at different times is included as well.

Download or read book Navy Lasers Railgun and Gun Launched Guided Projectile written by Congressional Service and published by Createspace Independent Publishing Platform. This book was released on 2018-07-18 with total page 42 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Navy is developing three new ship-based weapons that could improve the ability of Navy surface ships to defend themselves against missiles, unmanned aerial vehicles (UAVs), and surface craft: the Surface Navy Laser Weapon System (SNLWS), the electromagnetic railgun (EMRG), and the gun-launched guided projectile (GLGP), previously known as the hypervelocity projectile (HVP). The Navy refers to the initial (i.e., Increment 1) version of SNLWS as HELIOS, an acronym meaning high-energy laser with integrated optical dazzler and surveillance. EMRG could additionally provide the Navy with a new naval surface fire support (NSFS) weapon for attacking land targets in support of Marines or other friendly ground forces ashore. The Department of Defense is exploring the potential for using GLGP across multiple U.S. military services. Any one of these three new weapons, if successfully developed and deployed, might be regarded as a "game changer" for defending Navy surface ships against enemy missiles and UAVs. If two or three of them are successfully developed and deployed, the result might be considered not just a game changer, but a revolution. Rarely has the Navy had so many potential new types of surface-ship air-defense weapons simultaneously available for development and potential deployment. Although the Navy in recent years has made considerable progress in developing technologies for these new weapons, a number of significant development challenges remain. Overcoming these challenges will require additional development work, and ultimate success in overcoming them is not guaranteed. The issue for Congress is whether to approve, reject, or modify the Navy's funding requests and proposed acquisition strategies for these three potential new weapons. Potential oversight questions for Congress include the following: Using currently available air-defense weapons, how well could Navy surface ships defend themselves in a combat scenario against an adversary such as China that has or could have large numbers of missiles and UAVs? How would this situation change if Navy surface ships in coming years were equipped with SNLWS, EMRG, GLGP, or some combination of these systems? How significant are the remaining development challenges for SNLWS, EMRG, and GLGP? Are current schedules for developing SNLWS, EMRG, and GLGP appropriate in relation to remaining development challenges and projected improvements in enemy missiles and UAVs? When does the Navy anticipate issuing roadmaps detailing its plans for procuring and installing production versions of SNLWS, EMRG, and GLGP on specific Navy ships by specific dates? Will the kinds of surface ships that the Navy plans to procure in coming years have sufficient space, weight, electrical power, and cooling capability to take full advantage of SNLWS and EMRG? What changes, if any, would need to be made in Navy plans for procuring large surface combatants (i.e., destroyers and cruisers) or other Navy ships to take full advantage of SNLWS and EMRGs? Given the Navy's interest in HPV, how committed is the Navy to completing the development of EMRG and eventually deploying EMRGs on Navy ships? Are the funding line items for SNLWS, EMRG, and GLDP sufficiently visible for supporting congressional oversight?
