Past revolutions, future transformations what can the history of revolutions in military affairs tell us about transforming the U.S. military by Richard O Hundley ( Book )
3 editions published in 1999 in English and held by 1,022 libraries worldwide
Advances in technology can bring about dramatic changes in military operations, often termed "revolutions in military affairs" or RMAs. Such technology-driven changes in military operations are not merely a recent phenomenon: they have been occurring since the dawn of history, they will continue to occur in the future, and they will continue to bestow a military advantage on the first nation to develop and use them. Accordingly, it is important to the continued vitality and robustness of the U.S. defense posture for the DoD R & D community to be aware of technology developments that could revolutionize military operations in the future, and for the U.S. military services to be on the lookout for revolutionary ways in which to employ those technologies in warfare. This report examines the history of past RMAs, to see what can be learned from them regarding the challenge confronting the DoD today, when it has set out on a concerted effort to bring about a technology-driven transformation of the U.S. military to achieve the operational goals outlined in Joint Vision 2010. Among its many findings are three of particular note: RMAs are rarely brought about by dominant players (such as the U.S. military is today). For a dominant player to bring about an RMA requires a receptive organizational climate, fostering a continually refined vision of how war may change in the future and encouraging vigorous debate regarding the future of the organization; senior officers with traditional credentials willing to sponsor new ways of doing things and able to establish new promotion pathways for junior officers practicing a new way of war; mechanisms for experimentation, to discover, learn, test and demonstrate new ideas; and ways of responding positively to the results of successful experiments, in terms of doctrinal changes, acquisition programs, and force structure modifications. The DoD has some of these elements today, but is missing others. The report makes specific suggestions regarding ways of filling in the missing elements. Doing these things will facilitate DoD's force transformation activities and help ensure that the next RMA is brought about by the United States. and not some other nation.
Innovative management in the DARPA high altitude endurance unmanned aerial vehicle program phase II experience by Jeffrey A Drezner ( Book )
2 editions published in 1999 in English and held by 858 libraries worldwide
The U.S. military's development of Unmanned Aerial Vehicles (UAVs) has been hampered by cost overruns, schedule slippage, and disappointing operational results. The High Altitude Endurance UAV (HAE UAV) joint program, initiated under the direction of the Defense Advanced Research Projects Agency (DARPA), incorporates several innovative elements in its acquisition strategy that depart radically from traditional acquisition approaches. The program's development phase for the Global Hawk and DarkStar air vehicles is analyzed in this research. The HAE UAV program has experienced problems that are typical of newly implemented methods, but it has produced significant benefits, and provides lessons that could improve a wide variety of future acquisition processes.
The arsenal ship acquisition process experience contrasting and common impressions from the contractor teams and joint program office by Robert S Leonard ( Book )
8 editions published between 1998 and 1999 in English and held by 787 libraries worldwide
The Arsenal Ship acquisition program was unique in two respects: it represented a new operational concept for Navy weapon systems, and its management structure and process represented a significant departure from traditional military ship-building programs. The Arsenal Ship program was, in effect, an experiment; while the Navy envisioned an array of mission capabilities for the ship, it set the project budget as the single immovable requirement. In the end, political and financial constraints caused the program's cancellation. Nevertheless, its acquisition approach and technical innovations have already had--and will continue to have--significant influence on other Navy ship-building programs. The lessons learned from the Arsenal Ship program, applied to existing and planned systems, should more than recover the money spent on it.
Finding and fixing vulnerabilities in information systems the vulnerability assessment & mitigation methodology ( Book )
2 editions published in 2003 in English and held by 384 libraries worldwide
Understanding an organization's reliance on information systems and how to mitigate the vulnerabilities of these systems can be an intimidating challenge--especially when considering less well-known weaknesses or even unknown vulnerabilities that have not yet been exploited. The authors, understanding the risks posed by new kinds of information security threats, build on previous RAND mitigation techniques by introducing the Vulnerability Assessment and Mitigation (VAM) methodology. The six-step procedure uses a top-down approach to protect against future threats and system failures while mitigating current and past threats and weaknesses. The authors lead evaluators through the procedure of classifying vulnerabilities in their systems' physical, cyber, human/social, and infrastructure elements, and identifying which security techniques can be relevant for these vulnerabilities. The authors also use VAM to break down information compromises into five fundamental components of attack or failure: knowledge, access, target vulnerability, non-retribution, and assessment. In addition, a new automated tool implemented as an Excel spreadsheet is discussed; this tool greatly simplifies using the methodology and emphasizes analysis on cautions, risks, and barriers.

Combat in hell : a consideration of constrained urban warfare by Russell W Glenn ( Book )
1 edition published in 1996 in English and held by 192 libraries worldwide
Armed forces are ever more likely to fight in cities as the world becomes increasingly urbanized. Accordingly, public and moral concerns about the costs of war borne by noncombatants increase as well. This report is a study of urban warfare and its challenges for U.S. armed forces constrained by having to minimize noncombatant casualties and collateral damage. America's armed forces are likely to have to confront the hell of urban combat. They have the potential to do so successfully. However, this environment's challenging character is unalterable; it will consume any force that fights unprepared. This study, based on an in-depth literature search and scores of interviews, has three primary objectives: (1) Describe the conditions confronting a ground force fighting under the constraints of minimizing noncombatant casualties and collateral damage, along with the difficulties of fighting under such conditions in urban areas; (2) Identify U.S. armed forces' current capabilities and ongoing efforts to enhance them; and (3) Determine current shortfalls and present potential remedies for identified vulnerabilities. Consideration of such solutions will include analysis of feasible changes in doctrine, training, and technologies that would give regular U.S. forces the capability to successfully perform constrained urban operations.

An exploration of cyberspace security R&D investment strategies for DARPA : "the day after-- in cyberspace II by Robert H Anderson ( Book )
2 editions published in 1996 in English and held by 170 libraries worldwide
In recent years, a RAND-developed "The Day After..." exercise methodology has been used to explore strategic planning options, both for nuclear proliferation and counter-proliferation, and for questions involving "security in cyberspace" and "information warfare" (IW). On March 23, 1996, a "The Day After...in Cyberspace" exercise with approximately 60 participants was conducted at RAND's Washington D.C. offices, under the sponsorship of the Defense Advanced Research Projects Agency. The purpose was to generate suggestions and options regarding research and development initiatives to enhance the security of the U.S. information infrastructure. The scenario in the exercise involved a Mideast crisis situation, with Iran as an aggressor. Exercise participants discussed both short-term technical fixes to counter IW attacks that were hypothesized to occur in the year 2000 and longer-term research strategies that could be initiated now to avoid significant vulnerabilities in the future.

Experiments in multiresolution modeling (MRM) by Paul K Davis ( Book )
2 editions published in 1998 in English and held by 151 libraries worldwide
This study describes the motivation for multiresolution modeling (MRM) within a single model or a family of models. After introducing a new measure of consistency for models of different resolution, the study discusses in some depth obstacles to and methods for multiresolution modeling (also called variable-resolution modeling), illustrating issues with a detailed military example involving precision fires. The study highlights the value of visual design, array formalism, formal mathematics to identify natural aggregation fragments, integrated hierarchical variable resolution (IHVR) yielding "trees" of variables, estimation theory, alternative aggregate representations called out in a user interface, "stretcher variables, " and computational methods to identify natural phase transitions and facilitate calibrations. The study recommends that major Department of Defense models such as JWARS emphasize MRM and related research on family-of-models issues. It notes that MRM is not an all-or-nothing matter and that incorporating even some multiresolution features can be quite useful. Finally, the study notes that MRM is a frontier issue and suggests directions for further research.
