A trajectory for homeland ballistic missile defense

The Ground-based Midcourse Defense system is intended to protect the US homeland against limited attacks from intermediate- and long-range ballistic missiles. It has succeeded in intercepting target missiles and can engage a threat launched from North Korea or the Middle East, targeting any point in the USA. Nevertheless, high-profile struggles and program changes related to homeland ballistic missile defense (BMD) continue to make headlines. The most significant struggle has been a string of three straight intercept test failures over five years, followed by the recent successful intercept test in June 2014. This article first briefly reviews the current threats of concern. It then examines homeland BMD policy objectives, followed by the current major technical issues in supporting these objectives and, then, the likelihood of negating a warhead. Finally, it highlights major considerations that should be part of the trajectory the US government takes moving forward.

Missile defense and strategic stability: Terminal High Altitude Area Defense (THAAD) in South Korea

South Korea is threatened by its troubled relationship with North Korea. North Korea possesses a large cache of missiles as well as chemical and biological weapons, and the future potential to mount nuclear weapons on its missiles. The United States is also challenged because of its defense commitments to Seoul. As a countermeasure, the United States and South Korea decided to deploy Terminal High Altitude Area Defense (THAAD) missile defenses in South Korea. However, China has objected. Chinese scholars believe the THAAD radar would be able to track Chinese inter-continental ballistic missiles, thereby weakening their deterrent. A technical analysis does not support this assertion. However, it is vital for South Korea, given its proximity and economic interdependence, to reassure China. South Korea should highlight that THAAD will be deployed by the United States Forces Korea and is not a commitment by Seoul to become part of U.S.-led missile defenses in the Asia-Pacific.

ADVANCED US CONVENTIONAL WEAPONS AND NUCLEAR DISARMAMENT

The Obama administration has made a great effort to increase the role of advanced conventional weaponry in US national security thinking and practice, in part to help reinvigorate the global nuclear disarmament agenda by reducing the role played by nuclear weapons in the US defense posture. However, such a strategy is fundamentally flawed because increases in US conventional superiority will exacerbate US relative strength vis-à-vis other powers, and therefore make the prospect of a nuclear weapon-free world seem less attractive to Washington's current and potential nuclear rivals. Consequently, it is highly likely that the impact of efforts to increase US advanced conventional superiority through ballistic missile defense and a conventional “prompt global strike” program will ensure that the Obama administration is adopting a pathway to nuclear abolition on which it is the sole traveler for the foreseeable future.     

反舰导弹大空域变轨的三维扩展比例导引律

为了使大空域变轨弹道的理论研究更符合反舰导弹的实际运动状态,建立了反舰导弹追踪虚拟目标的三维空间相对运动模型。同时,为了保证反舰导弹大空域变轨弹道的四段弹道平滑过渡,在导引律设计时同时考虑了脱靶量要求和末端落角要求。应用Lyapunov稳定性理论求解出满足要求的三维扩展比例导引律,对大空域变轨弹道的四段弹道设计了相应的过载控制指令,并进行了仿真研究。仿真结果表明:所提出的三维扩展比例导引律可以使反舰导弹顺利完成大空域飞行任务,而且保证了反舰导弹的所有性能指标均满足要求。
