Don't stop with Joint Forces Command … cut AFRICOM too

Abstract

The United States Africa Command (AFRICOM) has been a military success but a strategic messaging failure. The United States’ relationships across Africa cannot be boiled down to military affairs. This paper argues that Africa has many more opportunities than challenges and thus requires a more balanced foreign policy solution from Washington DC than a new military command. For the military engagement that does need to take place, a more low-profile approach would benefit the United States in Africa.     

从X-47B看美国无人作战飞机发展

无人作战飞机代表了航空装备无人化发展的方向.美国X-47B无人作战飞机已经完成了航母上自主弹射起飞和拦阻着舰,标志着美军海空作战模式将发生革命性的改变.这是人类的一小步,但对于无人系统来说却是技术发展的一大步.文章以X-47B为例,回顾了美军无人作战飞机的发展历程,分析了美军对无人作战飞机的概念和认识的变化,以及无人作战飞机对未来空中作战的影响,总结了值得借鉴的经验和教训.

An enterprise portfolio approach for defence capability planning

Capability-based planning (CBP) is considered by many defence organisations to be the best practice for enterprise-level planning, analysis and management. This approach, loosely based around investment portfolio theory, is premised on balancing the cost, benefit and risk of capability options across the defence enterprise. However a number of authors have recently noted limitations of its current applications. The authors propose a more general, insurance-based approach, which can support the evolutionary improvement of the current CBP approach. This approach is implemented as hedging-based planning and aims to better reflect the enterprise nature of defence organisations, capturing both force structure and force generation aspects of military systems.     

舰载预警机防空预警探测距离需求分析

提出了一种舰载预警机防空预警探测距离需求确定方法。首先对舰载预警机执行防空预警作战进行了描述,为满足拦截机对敌突击飞机进行成功拦截,预警机的预警探测距必须大于一个阈值,即所需最小预警探测距离。其次分析了舰载预警机所需最小防空预警探测距离与敌突击飞机速度、航母防空拦截机响应时间和速度之间的关系,构建了舰载预警机防空所需最小预警探测距离计算模型;最后应用典型案例,计算了多种防空想定下舰载预警机所需最小预警探测距离,仿真分析了敌突击飞机速度和航母防空拦截机速度对舰载预警机防空所需最小预警探测距离的影响。论文的研究结果为舰载预警机装备研制和作战使用提供决策依据。     

Goodbye to all that: On small wars and big choices

This article reflects on a decade of British counterinsurgency operations. Questioning the idea that lessons have been learnt, the paper challenges the assumptions that are being used to frame future strategic choice. Suggesting that defence engagement is primarily focused on optimising overseas interventions while avoiding a deeper strategic reassessment about whether the UK should be undertaking these sorts of activities, the article calls for a proper debate on Britain's national security interests.     

Conjectures for framing cyberwarfare

Cyberspace has emerged as a potentially new (and unconventional) domain for warfare. Much debate has focused on understanding cyber conflict. The ability to critically analyse this phenomenon is important; however, the nascent nature of cyberwarfare and the complexity of the systems involved create challenges not met by conventional approaches. As a first step, this requires an analytical construct to frame discussions in a way that highlights distinct characteristics of the cyber domain. An approach proposed is one of the postulating conjectures for debate as a way to achieve this and to demonstrate its use, both at the strategic and operational levels. It is suggested that such an approach provides one component of a mature analytical framework for the analysis of cyber across a range of warfare domains.     

防空系统建模与目标价值排序方法

针对当前防空系统模型的构建和评估偏向于定性处理以及仅考虑其结构特性而忽视了系统中目标与关系自身属性的问题,在分析现有模型与评估方法的基础上,提出了基于邻接矩阵的防空系统模型,定义了能力评估向量,采用目标对体系能力贡献程度的目标价值综合评价方法,并引用Pareto占优中等级前沿和拥挤距离的思想提出了目标等级和目标离散度的概念,形成了非劣性价值排序算法,同时使用加权以及性价比方法和其他网络评估方法排序,采用自身设计以及随机生成案例进行仿真实验,结果验证了基于邻接矩阵的防空系统模型以及价值排序算法的有效性。     

防空体系作战能力灰色聚类评估

从分析现代防空体系的组成出发,建立了较完备的防空体系作战能力评估指标体系,提出了一种基于灰色定权聚类和三角白化权函数的防空体系作战能力灰色聚类评估方法,并通过算例对方法的有效性进行了检验。结果表明该方法用于防空体系作战能力的评估是切实可行的。
