Cluster Weapons – Military Utility and Alternatives
FFI-rapport/2007/02345 Cluster weapons – military utility and alternatives Ove Dullum Forsvarets forskningsinstitutt/Norwegian Defence Research Establishment (FFI) 1 February 2008 FFI-rapport 2007/02345 Oppdrag 351301 ISBN 978-82-464-1318-1 Keywords Militære operasjoner / Military operations Artilleri / Artillery Flybomber / Aircraft bombs Klasevåpen / Cluster weapons Ammunisjon / Ammunition Approved by Ove Dullum Project manager Jan Ivar Botnan Director of Research Jan Ivar Botnan Director 2 FFI-rapport/2007/02345 English summary This report is made through the sponsorship of the Royal Norwegian Ministry of Foreign Affairs. Its purpose is to get an overview of the military utility of cluster munitions, and to find to which degree their capacity can be substituted by current conventional weapons or weapons that are on the verge of becoming available. Cluster munition roughly serve three purposes; firstly to defeat soft targets, i e personnel; secondly to defeat armoured of light armoured vehicles; and thirdly to contribute to the suppressive effect, i e to avoid enemy forces to use their weapons without inflicting too much damage upon them. The report seeks to quantify the effect of such munitions and to compare this effect with that of conventional weapons and more modern weapons. The report discusses in some detail how such weapons work and which effect they have against different targets. The fragment effect is the most important one. Other effects are the armour piercing effect, the blast effect, and the incendiary effect. Quantitative descriptions of such effects are usually only found in classified literature. However, this report is exclusively based on unclassified sources. The availability of such sources has been sufficient to get an adequate picture of the effect of such weapons. -

Explosive Weapon Effectsweapon Overview Effects
CHARACTERISATION OF EXPLOSIVE WEAPONS EXPLOSIVEEXPLOSIVE WEAPON EFFECTSWEAPON OVERVIEW EFFECTS FINAL REPORT ABOUT THE GICHD AND THE PROJECT The Geneva International Centre for Humanitarian Demining (GICHD) is an expert organisation working to reduce the impact of mines, cluster munitions and other explosive hazards, in close partnership with states, the UN and other human security actors. Based at the Maison de la paix in Geneva, the GICHD employs around 55 staff from over 15 countries with unique expertise and knowledge. Our work is made possible by core contributions, project funding and in-kind support from more than 20 governments and organisations. Motivated by its strategic goal to improve human security and equipped with subject expertise in explosive hazards, the GICHD launched a research project to characterise explosive weapons. The GICHD perceives the debate on explosive weapons in populated areas (EWIPA) as an important humanitarian issue. The aim of this research into explosive weapons characteristics and their immediate, destructive effects on humans and structures, is to help inform the ongoing discussions on EWIPA, intended to reduce harm to civilians. The intention of the research is not to discuss the moral, political or legal implications of using explosive weapon systems in populated areas, but to examine their characteristics, effects and use from a technical perspective. The research project started in January 2015 and was guided and advised by a group of 18 international experts dealing with weapons-related research and practitioners who address the implications of explosive weapons in the humanitarian, policy, advocacy and legal fields. This report and its annexes integrate the research efforts of the characterisation of explosive weapons (CEW) project in 2015-2016 and make reference to key information sources in this domain. -

Historic Barriers to Anglo-American Nuclear Cooperation
3 HISTORIC BARRIERS TO ANGLO- AMERICAN NUCLEAR COOPERATION ANDREW BROWN Despite being the closest of allies, with shared values and language, at- tempts by the United Kingdom and the United States to reach accords on nuclear matters generated distrust and resentment but no durable arrangements until the Mutual Defense Agreement of 1958. There were times when the perceived national interests of the two countries were unsynchronized or at odds; periods when political leaders did not see eye to eye or made secret agreements that remained just that; and when espionage, propaganda, and public opinion caused addi- tional tensions. STATUS IMBALANCE The Magna Carta of the nuclear age is the two-part Frisch-Peierls mem- orandum. It was produced by two European émigrés, Otto Frisch and Rudolf Peierls, at Birmingham University in the spring of 1940. Un- like Einstein’s famous letter to President Franklin D. Roosevelt, with its vague warning that a powerful new bomb might be constructed from uranium, the Frisch-Peierls memorandum set out detailed technical arguments leading to the conclusion that “a moderate amount of U-235 [highly enriched uranium] would indeed constitute an extremely effi- cient explosive.” Like Einstein, Frisch and Peierls were worried that the Germans might already be working toward an atomic bomb against which there would be no defense. By suggesting “a counter-threat with a similar bomb,” they first enunciated the concept of mutual deterrence and recommended “start[ing] production as soon as possible, even if 36 Historic Barriers to Anglo-American Nuclear Cooperation 37 it is not intended to use the bomb as a means of attack.”1 Professor Mark Oliphant from Birmingham convinced the UK authorities that “the whole thing must be taken rather seriously,”2 and a small group of senior scientists came together as the Maud Committee. -
M-1392 Publication Title: Bush-Conant File
Publication Number: M-1392 Publication Title: Bush-Conant File Relating to the Development of the Atomic Bomb, 1940-1945 Date Published: n.d. BUSH-CONANT FILE RELATING TO THE DEVELOPMENT OF THE ATOMIC BOMB, 1940-1945 The Bush-Conant File, reproduced on the 14 rolls of this microfilm publication, M1392, documents the research and development of the atomic bomb from 1940 to 1945. These records were maintained in Dr. James B. Conant's office for himself and Dr. Vannevar Bush. Bush was director of the Office of Scientific Research and Development (OSRD, 1941-46), chairman of the National Defense Research Committee (NDRC) prior to the establishment of OSRD (1940-41), chairman of the Military Policy Committee (1942-45) and member of the Interim Committee (May-June 1945). During this period Conant served under Bush as chairman of the National Defense Research Committee of OSRD (1941-46), chairman of the S-1 Executive Committee (1942-43), alternate chairman of the Military Policy Committee (1942-45), scientific advisor to Maj. Gen. Leslie R. Groves (1943-45), and member of the Interim Committee (May-June 1945). The file, which consists primarily of letters, memorandums, and reports, is part of the Records of the Office of Scientific Research and Development, Record Group (RG) 227. The Bush-Conant File documents OSRD's role in promoting basic scientific research and development on nuclear fission before August 1942. In addition, the files document Bush and Conant's continuing roles, as chairman and alternate chairman of the Military Policy Committee, in overseeing the army's development of the atomic bomb during World War II and, as members of the short-lived Interim Committee, in advising on foreign policy and domestic legislation for the regulation of atomic energy immediately after the war. -

Biographical Memoir COPYRIGHT 1996 NATIONAL ACADEMIES PRESS WASHINGTON D.C. MERLE ANTONY TUVE June 27, 1901–May 20, 1982 BY PHILIP H. ABELSON ERLE ANTONY TUVE WAS a leading scientist of his times. MHe joined with Gregory Breit in the first use of pulsed radio waves in the measurement of layers in the ionosphere. Together with Lawrence R. Hafstad and Norman P. Heydenburg he made the first and definitive measurements of the proton-proton force at nuclear distances. During World War II he led in the development of the proximity fuze that stopped the buzz bomb attack on London, played a crucial part in the Battle of the Bulge, and enabled naval ships to ward off Japanese aircraft in the western Pacific. Following World War II he served for twenty years as director of the Carnegie Institution of Washington’s Department of Ter- restrial Magnetism, where, in addition to supporting a mul- tifaceted program of research, he personally made impor- tant contributions to experimental seismology, radio astronomy, and optical astronomy. Tuve was a dreamer and an achiever, but he was more than that. He was a man of conscience and ideals. Throughout his life he remained a scientist whose primary motivation was the search for knowledge but a person whose zeal was tempered by a regard for the aspirations of other humans. -

Guidance and control of artillery projectiles will be critical to future military operations. With the large quantities of unguided artillery shells stockpiled around the world, the course correction fuze could provide an attractive and cost-effective solution for munition control. This report proposes a drag brake and a spin brake course correction fuze concept, and compares their performance against the roll-decoupled four canard configuration. Specific guidance and control functions were designed and tuned for each using the 155 mm spin-stabilized artillery projectile as baseline. Dispersion sources included variations in muzzle velocity and gun’s azimuth and elevation angles relative to nominal conditions, and wind velocity perturbations. Monte Carlo simulations were performed to analyze the delivery accuracy. Results show that the drag brake concept compensates for muzzle velocity and longitudinal wind perturbations efficiently. -
Physics, Physicists and the Bomb
editorial Physics, physicists and the bomb Scientists involved in nuclear research before and after the end of the Second World War continue to be the subjects of historical and cultural fascination. Almost 70 years since Hiroshima and Nagasaki, the military, historical and moral implications of the nuclear bomb remain firmly lodged in the public’s consciousness. Images of mushroom clouds serve as powerful reminders of the destructive capability that countries armed with nuclear weapons have access to — a capability that continues to play a primary role in shaping the present geopolitical landscape of the world. For physicists, the development of the nuclear bomb generally brings up conflicting feelings. On the one hand, physicists played a central role in helping to create it; on the SCIENCE SOURCE/SCIENCE PHOTO LIBRARY PHOTO SOURCE/SCIENCE SCIENCE other, they were also among the first to realize © its terrifying power. This contradiction is most Manhattan Project physicists at Los Alamos. From left to right: Kenneth Bainbridge, Joseph Hoffman, famously epitomized by Robert Oppenheimer, Robert Oppenheimer, Louis Hempelmann, Robert Bacher, Victor Weisskopf and Richard Dodson. the scientific director of the Manhattan Project, who, on witnessing the first test of the atomic bomb, the Trinity test, in July 1945, in this context that the public can truly come race following the Second World War, there was reminded of a quote from the Hindu to feel the growing sense of disillusionment is no question that Churchill was an early scripture Bhagavad Gita: “Now, I am become of those scientists as they realized their goal; and influential champion for government- Death, the destroyer of worlds.” a sense of lost innocence, that knowledge that sponsored science and technology in Britain. -
In Defense of Freedom-The Early Years
WALTER G. BERL IN DEFENSE OF FREEDOM - THE EARLY YEARS This article describes the events that led to the founding of the Applied Physics Laboratory. It summarizes the development of a novel fuze for rotating antiaircraft ammunition and the organization that achieved it, continues with a discussion of the early stages of the development of a new technology for the delivery of warheads-the guided missile, and concludes with a brief sketch of Merle A. Tuve' s career that led to his involvement with these programs.
