This article analyzes India's efforts to deploy a Ballistic Missile Program (BMD). The article has three objectives. First, it argues that scientific-bureaucratic factors and India's incapacity to deter Pakistan's use of terrorist proxies have driven its quest for BMD. Second, the article also evaluates the current state of India's two-tiered missile defense shield. In spite of various claims on the part of India's defense science establishment, the paper estimates that India still lacks a deployable BMD system and is still far from developing an effective strategy of deterrence-through-denial. Third, the article analyzes the implications of the development of India's BMD system for nuclear stability in South Asia. The article shows how India's BMD capacities, however limited, have indirectly exacerbated the security concerns of India's regional rival, Pakistan. 相似文献

The damage effects of fluid-filled submunition payload impacted by the kinetic kill vehicle (KKV) are investigated by simulations and ground-based experiments. Numerical simulations showed that the damage level and number of submunitions were significantly influenced by the diameter of the KKV compared with its length. Based on that, a high velocity penetrator formed by shaped charge explosion was used to simulate the direct hit experiment of a KKV impacting submunition payload. Experimental results demonstrated that the damage modes of submunitions mainly included the slight damage, perforation and total smash, showing a good agreement with the simulations. To understand the multiple damage modes of submunitions, the damage behavior of the submunitions in direct hit process were analyzed based on the AUTODYN-3D code. Numerical results presented that increased KKV diameter can increase the crater diameter and expand the damage volume, which will achieve a higher direct hit lethality. Further analysis indicated that there were other mechanical behaviors can enhance the damage to submunitions not lying in the KKV flight path, such as secondary debris kill, neighboring submunitions collision with each other, and high-speed fluid injection effect. 相似文献

在地地弹道式导弹与航空母舰攻防对抗中,需要研究航母是否在导弹进攻的有效区内。针对具有末制导的弹道式导弹具有再入机动变轨特性,建立了导弹再入机动飞行模型,提出了导弹在不同的再入条件下,对其飞行弹道及机动能力进行仿真计算的方法,通过仿真确定出了导弹打击航空母舰的有效区域。在此基础上,探讨了导弹在以不同的再入姿态、不同的再入飞行高度实施末制导时,导弹落点的有效区域、边界外形及有效区的变化范围。从所得结果来看,所建模型及仿真方法正确可行,在一定程度上解决了弹道导弹打击航空母舰战斗群作战保障急需解决的一些问题。 相似文献
