Fact Sheet

28,800: The total number of intact nuclear warheads retained by the United States and Russia. 30,000: Number of intact nuclear warheads throughout the world. 17,500 of these are operational. 128,000+: Estimated number of nuclear warheads built worldwide since 1945.

All but 2 percent of these nuclear warheads have been built by the United States (55 % or 70,000+) and Russia (43 % or 55,000+).

10,729: Total number of intact U.S. nuclear warheads (274 warheads are awaiting dismantlement) 10,455: Total warheads in the U.S. stockpile ~7,000: Number of operational strategic U.S. nuclear weapons ~1,600: Number of U.S. tactical nuclear weapons (~800 of these are operational) 8,400: Total number of operational nuclear warheads in Russian arsenal 5,000: Approximate number of Russian strategic nuclear weapons 3,400: Approximate number of operational Russian tactical nuclear weapons

(total tactical arsenal said to comprise as many as 10,000+ weapons) 3,500: Approximate number of strategic U.S. nuclear weapons, year 2003 under START II. 3,000: Approximate number of strategic Russian nuclear weapons, year 2003 under START II. ~2,000: Maximum number of deployed strategic nuclear weapons that will remain in the U.S.

and Russian arsenals by 2012 ( The Treaty of Moscow (also known as SORT) signed by U.S. President George W. Bush and Russian President Vladimir Putin in May 2002.

10,000: The number of warheads the United States will retain in 2012 (essentially the same number as today)

$3.5 trillion: Amount the United States spent between 1940 and 1995 to prepare to fight a nuclear war. $27 billion: Amount the United States spends annually to prepare to fight a nuclear war. $2.2 billion: Cost for one B-2 bomber (21 were authorized by Congress). $2.5 billion: The lifecycle cost of each B-2 (RDT&E, procurement, operations, maintenance, support).The figures cited above were gathered with the aid of resources from the National Resources Defense Council (NRDC) http://www.nrdc.org/nuclear/nudb/datainx.asp and the Secretary of Defense Office http://www.acq.osd.mil/ncbdp/nm/index.htm

Medical Consequences

The U.S. "Federal Emergency Management Agency" predicts approximately86,000,000 people dead and 34,000,000 severely injured in the United States. Thereare about 2,000,000 hospital beds in Canada and U.S.A. combined.

"Lethal effects of radiation can be summarized briefly: a very high dose (5000 rads +)causes death in hours; a smaller but lethal dose (400 rads +): death in weeks. In thelatter case, sickness starts with diarrhea and vomiting, followed by some temporaryimprovement, and then the same symptoms recur with the addition of hemorrhage,anemia, infections, and a slow death."

The Bomb Test Series

SyllabusThe course on Nuclear Warfare PHYS 20061 is offered by the PhysicsDepartment, co-listed by the Reilly Center of Technology and Values and theKroc institute for International Peace Studies as an introductory course fornon-science majors to provide an overview about the broad range of topicsand aspects of nuclear weapons and warfare in the 20th century.

Class ContentThe course will start with the history and emergence of weapons of massdestruction technologies as a consequence of World War I and World War II,culminating in the development and use of the nuclear bomb. This will befollowed by a discussion of the underlying physics principles to provide thenecessary background for a basic understanding of nuclear weaponstechniques and nuclear weapons effects as well as the decay radiationdriven consequences. These consequences will be discussed in terms ofshort-range, atmospheric, biological, and medical effects together with theimplications for social groups and societies. This will be complemented by anextensive discussion of the legal, political, and ethical implications ofpossession and use of nuclear weapons and nuclear warfare.
