The arsenal ship acquisition process experience : contrasting and common impressions from the contractor teams and joint program office by Robert S Leonard( Book )

7 editions published in 1999 in English and Undetermined and held by 165 WorldCat member 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
Innovative management in the DARPA high altitude endurance unmanned aerial vehicle program : phase II experience by Jeffrey A Drezner( Book )

5 editions published in 1999 in English and held by 163 WorldCat member 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 Global Hawk unmanned aerial vehicle acquisition process : a summary of phase I experience( Book )

5 editions published in 1997 in English and held by 156 WorldCat member libraries worldwide

There is a long history of efforts to improve the efficiency and effectiveness of the weapon acquisition process. The purpose of this case study is to understand how one such program, the High Altitude Endurance Unmanned Aerial Vehicle (HAE UAV), has benefited from certain changes from established acquisition procedures. The Defense Advanced Research Projects Agency, in conjunction with the Defense Airborne Reconnaissance Office, is embarking on development of two UAVs: Tier II+ and Tier III-. The development programs incorporate many novel acquisition practices, including a rigid price cap for future production items, together with waivers of most acquisition-specific laws and policies. This study will examine how the various innovations in acquisition management methods affect the program outcomes and how the lessons of these projects might be applied to a wider variety of projects to improve Department of Defense acquisition strategies. The study was initiated in fiscal year 1994 and will continue through the first three phases of the program. A final report will be issued at the end, preceded by periodic interim reports. This is the first such interim report, covering Phase 1 of the Tier II+ segment of HAE UAV
High-altitude airships for the future force Army by Lewis Jamison( Book )

6 editions published in 2005 in English and held by 135 WorldCat member libraries worldwide

Across the services, there is an increasing demand for overhead communications capacity. New, lighter-than-air (LTA) vehicles that operate at very high altitudes have an obvious attraction for planners of surveillance and communication missions; the ability to see to a more distant horizon results in greatly expanded surveillance volumes. This report informs the U.S. Army about the usefulness and limitations of high-altitude airships (HAA) in the role of platforms for communications and surveillance suites in theater battlespace. Potential alternatives are solar-powered HAA and airplanes flying at 65,000 feet or above that can remain geostationary for months. Potentially, HAA may provide communications satellite capabilities for the WIN-T network that are less expensive than satellites and may support a Global Hawk-like surveillance package in the Multi-Sensor Command and Control Constellation (MC2C). HAA performance issues include engine power, envelope strength, and permeability, solar-cell power, fuel-cell capacity, weather, launch and recovery, and air defense survivability
Astronomical odds : a policy framework for the cosmic impact hazard by Geoffrey Sommer( Book )

5 editions published between 2004 and 2005 in English and held by 120 WorldCat member libraries worldwide

Addresses the cosmic impact hazard (the threat to the Earth posed by asteroids and comets) as an extreme example of a low-probability, high-consequence policy problem. This analysis presents a comprehensive framework for dealing with the technical and societal uncertainties surrounding the impact hazard. It reviews the physical nature of the threat and both the history and mechanisms of society's response to the hazard, dwelling on the social costs of false positives. The author constructs an illustrative cost-benefit model on the foundations of prior work, with parameters of social response added and then varied to assess the robustness of a proposed policy intervention: social reassurance by means of a demonstrated mitigation capability. He concludes by noting that a common flaw of prior analysis is to give lip service to "low probability" and to focus instead on "high consequence"; that there is frequent confusion between ex ante and ex post perspectives; that uncertain costs are often treated as nonexistent costs; and that warning is a social function, not a technical function, and those who issue warnings of a given hazard should not stand to benefit from those warnings
