This article presents an overview of the history of development and the current status of the Soviet and Russian early-warning system, which was built to provide the Soviet strategic forces with information about a missile attack in an event of a nuclear conflict with the United States. Two main components of this system are considered--the network of early-warning radars, and the space-based early-warning system, which includes satellites on highly-elliptical and geosynchronous orbits. The system appears to be capable of detecting a massive attack, but cannot be relied upon to detect individual missile launches.

The United States is in the midst of its third major debate on nationwide ballistic missile defense-the first culminating in the 1972 ABM Treaty and the second sparked by President Reagan's "Star Wars" speech in 1983. This time the Cold War is over, the objectives for the defense are limited, and technology has advanced to the point where some options may be technically feasible.

However, intercontinental ballistic missiles (ICBMs) are not the primary threat to the United States, as events since September 11 demonstrate. Other homeland defense programs, especially civil defenses against bioterrorism, are more important. Yet emerging missile states may acquire ICBMs some day. To the extent that this is a concern, diplomatic efforts can limit the spread of ballistic missiles, and deterrence can dissuade their use. National missile defense (NMD), then, is insurance against the relatively unlikely event that ICBMs will be launched against the United States.

If the United States decides to deploy a limited NMD, the questions become what type and how much? A midcourse NMD system (one that attempts to intercept missile warheads as they fall through outer space) of the sort proposed for deployment in Alaska is the most technically mature option and would probably work well enough against emerging ICBM threats to justify limited deployment, assuming that the threat materializes. However, such a defense should contain only about 20 interceptors to minimize adverse political reactions from Russia and China. Over the long run, midcourse defenses may be vulnerable to sophisticated countermeasures. Therefore, the United States should place greater emphasis on land, naval, and air-based boostphase intercept options (defenses that attempt to intercept the ballistic missile while its rocket motors are still burning) because they are more robust to countermeasures and they pose relatively little threat to Russia and China. Space-based boost-phase NMD systems have the advantage of global coverage; however, they are technically more challenging, probably more expensive, and more destabilizing.

This encyclopedic book edited by Pavel Podvig provides comprehensive data about Soviet and Russian strategic weapons, payloads, and delivery systems and on the nuclear complex that supports them. The data are drawn from open, primarily Russian sources. Information is presented chronologically, arranged by individual systems and facilities, and is not available elsewhere in a single volume.

Following an overview of the history of Soviet strategic forces, the book discusses the structure of the political and military leadership in the Soviet Union and Russia, the structure of the Russian military and military industry, nuclear planning procedures, and the structure of the command and control system. It describes the nuclear warhead production complex and the Soviet nuclear weapon development program. It then focuses on the individual services that constitute the so-called strategic triad--land-based intercontinental ballistic missiles, the strategic submarine fleet, and strategic aviation. It presents an overview of Soviet strategic defense, including air defense systems, the Moscow missile defense system, the radar and space-based early warning networks, and the space surveillance system. The book also includes a description of the Soviet nuclear testing program, including information on test sites and on all Soviet nuclear tests and peaceful nuclear explosions. It concludes with a look at the future of strategic nuclear weapons in Russia.
