Cyber War Will Not Take Place

A large collection of captured documents from the very highest levels of the Iraqi government offers a chance to gain insight into why Saddam Hussein was unwilling and unable to alter his strategy on the eve of the 2003 war that toppled his regime. This paper explores some of the perceptions and misperceptions that Saddam Hussein took away from the 1991 Gulf War and shows how they affected his decisionmaking on the eve of the war in 2003. It concludes with some thoughts on the policy implications of these findings.     

The Naval Intelligence Underpinnings of Reagan's Maritime Strategy

Washington's so-called Maritime Strategy, which sought to apply US naval might against Soviet vulnerabilities on its maritime flanks, came to full fruition during the 1980s. The strategy, which witnessed a major buildup of US naval forces and aggressive exercising in seas proximate to the USSR, also explicitly targeted Moscow”s strategic missile submarines with the aim of pressuring the Kremlin during crises or the early phases of global war. Relying on a variety of interviews and newly declassified documents, the authors assert that the Maritime Strategy represents one of the rare instances in history when intelligence helped lead a nation to completely revise its concept of military operations.     

Investigating optimal replacement of aging air force systems

An availability‐oriented approach has been developed to decide when to replace an aging system. For an existing system, it is optimal to operate another year if and only if the incremental cost per available year is less than the lifetime average cost per available year of a new aircraft. We illustrate our approach using United States Air Force KC‐135 tanker data. In demonstrating our approach, we find it will be optimal to replace the KC‐135 by the end of the decade.

中远程空空导弹多机协同中制导交接方法

针对在同类型空中平台协同作战条件下,中远程空空导弹中制导权在移交过程中存在信息突变的问题,提出采用"虚拟目标"法对突变信息进行渐近处理,使虚拟目标逐步向真实目标运动,最终"导弹—虚拟目标"视线角与"导弹—真实目标"视线角重合,则中制导权移交结束;提出三种不同的中制导权交接律,在目标不机动/机动两种情形下,通过仿真分析不同模式下的交接律对空空导弹过载的影响。仿真结果证实适当平缓地进行制导权移交能将突变信息转化为接近于目标机动形成的、导弹自身能够处理的突变信息。避免了直接交接使导弹过载突变到非正常值的情况,使中制导交接能够平稳进行。
