Weapon effectiveness and the shapes of damage functions

This paper provides a review of methods of assessing a fragmentation weapon's effectiveness against a point target or an area target with keeping the focus on the necessity of using the Carleton damage function with the correct shape factor.First,cookie-cutter damage functions are redefined to preserve the shape factor of and to have the same lethal area as the corresponding Carleton damage function.Then,closed-form solutions of the effectiveness methods are obtained by using those cookie-cutter damage functions and the Carleton damage function.Finally,the closed-form solutions are applied to calculate the probability of damaging a point target and the expected fractional damage to an area target for several attack scenarios by using cookie-cutter damage functions and the Carleton damage functions with different shape factors.The comparison of the calculation results shows that using cookie-cutter damage functions or the Carleton damage function with a wrong shape factor results in quite signifi-cant differences from using the original Carleton damage function with a correct shape factor when weapon's delivery error deviations are less than or comparable to the lengths of the lethal area and the aim point is far from a target.The effectiveness methods improved in this paper will be useful for mission planning utilizing the precision-guided munitions in circumstances where the collateral damage should be reduced.     

软件定义的航天器测试网络技术

航天器测试网络是航天器自动化测试运行、测试数据监测分析等测试业务运行的信息通道,它的性能将极大影响航天器试验测试效率与试验数据的应用效能。针对传统航天器测试网络存在的物理独立部署、人工迁移、存在数据孤岛以及无法高效交换共享的不足,本文参考借鉴软件定义网络技术,设计了基于虚拟局域网及软件定义网络技术的软件定义航天器测试网络。该测试网络技术具备良好的软件重构、区域隔离、测试信息汇聚共享性能,能够通过软件重构,自动化迁移部署航天器测试网络;通过网络区域逻辑隔离,确保各航天器测试指令运行区域受控、安全;通过全局测试数据汇聚实现多航天器测试数据的交换共享,从而有效解决了航天器测试网络快速部署、测试指令安全运行与测试数据交换共享的问题,有力推动了装备试验数据工程的建设工作。     

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.

The ‘Third’ US Offset Strategy and Europe’s ‘Anti-access’ Challenge

Over the last two decades, a number of countries (most notably China, Russia and Iran) have been developing so-called anti-access and area denial (A2/AD) capabilities, such as ballistic and cruise missiles, offensive cyber-weapons, electronic warfare, etc. The development of A2/AD capabilities by non-Western countries undermines the foundations of US power projection and global military-technological supremacy. In order to overcome, or at least mitigate, the impending A2/AD challenge, the US Department of Defense (DoD) began to roll out its so-called ‘third’ offset strategy in late 2014. The strategy aims to bring about innovative operational concepts and technologies and spur new doctrinal and organisational debates. This article assesses which of the operational concepts and capabilities informing current US discussions on offset may be relevant in the context of the A2/AD challenges Europeans face on their eastern ‘flank‘ and in their ‘extended southern neighbourhood‘, and which may not. Europeans must grapple with the same conceptual puzzle as the US: how to strike the right balance between defeating A2/AD capabilities and hedging against them, i.e. through alternative strategies that are less dependent on unhindered access and resort to asymmetric forms of warfare. However, they must take into account the geographical features of their eastern flank and extended southern neighbourhood, the level of technological maturity of their challengers, and their own military-technological prowess and political limitations. This suggests a somewhat different approach to offsetting A2/AD than that adopted by the US.
