  • What Did We Get for Our $30-Billion Investment in SDI/BMD? I
    What Did We Get For Our $30-Billion Investment In SDI/BMD? i What Did We Get For Our $30-Billion Investment in SDI/BMD? James A. Abrahamson Henry F. Cooper September 1993 ©National Institute for Public Policy, 1999 ii What Did We Get For Our $30-Billion Investment In SDI/BMD? SUMMARY AND CONCLUSIONS The basic issue addressed by this paper has to do with the value added by the existence of the Strategic Defense Initiative (SDI), acknowledging that, during the same timeframe, something on the order of $30-billion would have been spent pursuing research on the same technologies somewhere in the Department of Defense (DOD) anyway. As is supported in detail in the following text, SDI has been enormously productive by many standards and from many perspectives. From a geopolitical/geostrategic point-of-view, there is little question but that SDI induced the leadership of the former Soviet Union to return to the negotiating table after their 1983 walk-out and negotiate seriously toward deep reductions in nuclear arms, producing the first nuclear arms control agreements in history to do so. A number of authoritative sources, including former senior Soviet officials, have stated that Ronald Reagan's highly visible commitment to SDI was a significant factor in persuading Mikhail Gorbachev to give up the arms competition and change the course of the former Soviet Union from confrontation to cooperation with the West, hastening the end of the Cold War. What are these achievements worth? Certainly many times the $30-billion invested over the past 10-years. On January 29, 1990, Defense Secretary Dick Cheney announced a $167-billion reduction in the FY1990-94 Defense plan for the next 5-years alone.

Beginning with the principles of rocketry from early time to the present, Erik Bergaust classifies all forty-two current operational missiles into four basic categories : air-to-air ; air-to-surface ; surface- to-air; and surface-to-surface. From the Navy's highly sophisticated Polaris to the Sidewinder, widely used in Vietnam, the author pinpoints the type, propulsion, guid- ance, performance, and construction of each rocket. A picture and a short paragraph describing each rocket's military use, plus a glossary, are included. Inspection of liquid hydrogen engines. Hydro- gen is a powerful fuel and is often used in combination with liquid oxygen. Fuels are car- ried in the missile in separate tanks and are mixed in the rocket's combustion chamber where the burning takes place. / Bell ROCKETS of the ARMED FORCES By Erik Bergaust 76 6. P.

    NATIONAL AIR AND SPACE ARCHIVES Herbert Stephen Desind Collection Accession No. 1997-0014 NASM 9A00657 National Air and Space Museum Smithsonian Institution Washington, DC Brian D. Nicklas © Smithsonian Institution, 2003 NASM Archives Desind Collection 1997-0014 Herbert Stephen Desind Collection 109 Cubic Feet, 305 Boxes Biographical Note Herbert Stephen Desind was a Washington, DC area native born on January 15, 1945, raised in Silver Spring, Maryland and educated at the University of Maryland. He obtained his BA degree in Communications at Maryland in 1967, and began working in the local public schools as a science teacher. At the time of his death, in October 1992, he was a high school teacher and a freelance writer/lecturer on spaceflight. Desind also was an avid model rocketeer, specializing in using the Estes Cineroc, a model rocket with an 8mm movie camera mounted in the nose. To many members of the National Association of Rocketry (NAR), he was known as “Mr. Cineroc.” His extensive requests worldwide for information and photographs of rocketry programs even led to a visit from FBI agents who asked him about the nature of his activities. Mr. Desind used the collection to support his writings in NAR publications, and his building scale model rockets for NAR competitions. Desind also used the material in the classroom, and in promoting model rocket clubs to foster an interest in spaceflight among his students. Desind entered the NASA Teacher in Space program in 1985, but it is not clear how far along his submission rose in the selection process. He was not a semi-finalist, although he had a strong application.

  • Frequently Asked Questions About Ballistic Missile Defense
    Frequently Asked Questions A Guide about Ballistic Missile Defense This Guide is based on information contained in the 2009 Independent Working Group Report entitled Missile Defense, the Space Relationship, and the Twenty-First Century which can be downloaded at www.ifpa.org. The purpose of the Guide is to address the most often asked questions and to provide information about mis- sile defense. What is Ballistic Missile Defense? n A ballistic missile defense system detects, tracks, intercepts and destroys io t incoming ballistic missiles and/or their warhead payloads. A fully opera- s e tional defense consists of sensors to detect a missile launch and to track u q 1 the missile and warhead; interceptors to disable or destroy the missile or warhead; and a command and control system. A ballistic missile and/ or its warhead can be destroyed by an interceptor’s fragmentation war- head that explodes in its vicinity or by more modern “hit-to-kill,” direct impact technologies —i.e., by “hitting a bullet with a bullet.” Both types of intercept are known as “kinetic kill.” Work is also progressing on di- rected energy technologies such as lasers, which can destroy a missile and its warhead at the speed of light. Missile defense systems can be deployed on the ground, in the air, at sea, or in space and destroy missiles and their payloads during their three stages of flight: i.e., the boost, midcourse, and terminal phase. In theboost phase just after launch, the missile is especially vulnerable because it is relatively slow moving and it emits bright exhaust gases that are compar- atively easy for sensors to detect and track.
