Attack and defense of ICBMs deceptively based in a number of identical areas

On-site verification of ICBMs in the context of an arms control agreement might involve a situation where an inspector would choose one or more of a number of identical areas to inspect and would have confidence that the other areas had the same characteristics. This article considers optimal attack and defense of missiles deceptively based in a number of identical areas. The attacker may allocate warheads across areas as he desires and uniformly within areas. The defender may allocate interceptors across areas as he desires and either uniformly or preferentially within areas. The effect of restricting the defender to uniform allocation across areas is explored for various assumptions. Robustness of surviving missiles with respect to the number of attacking warheads is studied. Results are presented for a wide range of cases.     

Proliferation and critical risk

Does proliferation increase the risk of war between new nuclear powers? Two schools of thought ‐ proliferation pessimists and optimists ‐ offer very different answers. The former stress the first‐strike danger of nuclear‐armed ballistic missiles and the resulting crisis instability as a cause of preemptive war. The latter stress the caution‐inducing effects of nuclear warheads and fear of retaliation as a check on would‐be attackers.

To bridge the gap between these two schools, Daniel Ellsberg's concept of critical risk is used to show how the likelihood of war changes as new nuclear powers enlarge and improve their missile forces. Ellsberg's framework suggests that the danger of war is low between recent proliferators but rises as nuclear stockpiles grow, thereby changing the payoffs associated with striking first or striking second and increasing the danger of war due to accidents, miscalculations, and uncontrollable interactions between rival nuclear forces.

Ellsberg's framework also suggests that the transition from weaponization to secure second strike force is likely to be long and difficult, in part because short‐range missiles like India's Prithvi are better suited to strike first than to strike second, and in part because negative control procedures reduce the value of striking second, thereby increasing the attraction of a preemptive strike.     

U.S. SPACE WEAPONS

Under the administration of President George W. Bush, Pentagon rhetoric has increasingly articulated a more robust vision of space as a future battlefield. This analysis details some of the ongoing spending for research and development programs identified in current U.S. Air Force, Missile Defense Agency (MDA), and Defense Advanced Research and Planning Agency (DARPA) planning and budget documents related to “space control” and “space force projection.” This analysis finds that current support for “space superiority” and “space control” systems remains largely rhetorical—with little actual budgetary support. Unclassified technology development programs included in the six-year Future Years Defense Plan are a decade or more away from deployment. Programs related to offensive counterspace, space-based missile defense interceptors, and space-based strike total slightly less than $300 million in FY 2006 funding. We conclude significantly higher expenditures in research and development would be required to develop and deploy killer micro satellites, space-based missile defense interceptors, and military space planes.

Cover for Thor: Divine Deception Planning for Cold War Missiles

In the late 1950s, as intercontinental ballistic missiles (ICBMs) replaced bombers, the development of Soviet ICBMs prompted fears of strategic vulnerability in the West. The Eisenhower administration's decision to deploy Intermediate Range Ballistic Missiles (IRBMs) on the territory of NATO allies sought to redress the perceived vulnerability until American ICBMs were ready. British deception planners considered how to enhance the threat posed by the IRBMs. An outline plan codenamed ‘Celestial’ was intended to persuade the Soviets that the otherwise vulnerable missiles could not be readily neutralised. This article explores this deception and how such planning also sought to convey accurate information alongside disinformation. It also suggests that deception planners appear to have given little heed to the potentially counterproductive consequences of such an operation.

BALLISTIC TRAJECTORY

North Korea has been one of the world's most active suppliers of ballistic missile systems since the mid-1980s, but the nature of its missile export business has changed significantly during this period. Unclassified, publicly available data show that the great majority of known deliveries of complete missile systems from North Korea occurred before 1994. The subsequent fall-off took place a decade too early to be explained by the Proliferation Security Initiative of 2003. It can be explained by a combination of factors that have reduced demand. First, after selling production equipment for ballistic missiles to many states, especially in the Middle East, North Korea by the late 1990s had become primarily a supplier of missile parts and materials, not complete systems. Second, after Operation Desert Storm, some missile-buying states shifted their attention away from ballistic missiles in favor of manned aircraft, cruise missiles, and missile defense systems supplied by Western powers. Third, some states experienced pressure from the United States to curtail their dealings with North Korea. During the last decade, having shed most of its previous customer base, North Korea has entered a phase of collaborative missile development with a smaller number of state partners, particularly Iran and Syria. Its known sales of complete missile systems are relatively small and infrequent. North Korea's time as missile supplier to the Middle East at large has ended, but there is a risk that regional states will turn to North Korea as a supplier of nuclear technology in the future.
