Precision cyber weapon systems: An important component of a responsible national security strategy?

Given the advances made in conventional weapon capabilities, precision should by now be the accepted and expected norm in cyberspace as well. In this article I argue that developing precision cyber weapon systems, to be used during a lawful conflict, can be an important part of a responsible national security strategy to reduce the amount of violence and physical destruction in conflicts. I first describe a precision cyber weapon system in a military context. I then present three compelling rationales for the development of precision cyber weapon systems based on ethical, operational, and financial considerations. To support the position, I address several arguments that have been levied against their development. Thereafter I present several recommendations for a way ahead.     

From show of force to naval presence,and back again: the U.S. Navy in the Baltic, 1982–2017

This article discusses roles and missions of the United States Navy with a particular focus on the Baltic Sea. That particular sea has gained renewed political and military attention following Russia's resurgent and increasingly hybrid-offensive foreign policy. Baltic nations, uncertain of what the future holds, ought to look at sea power and maritime missions in the Baltic, as well as US naval presence in Europe, to draw lessons for future posture.     

论“空海一体战”与中国国家安全

“空海一体战”是美国的一种新型作战理论,是在20世纪80年代“空地一体战”等诸多战法及兵种妥协基础上形成的一种新型军事战略,旨在通过空海军力量的配合,进行近域作战,以抵消对手的反进入/区域拒止能力,取得战争的主动权与控制权.“空海一体战”作为美国战略重心东移的重要角力点与支撑要素,在美国亚太战略中的作用举足轻重,对亚太周边国家尤其是中国的国家安全构成重大威胁,为此有必要对其理论渊源、发展目标、策略行动及障碍缺陷进行剖析与解构,为中国维护国家安全,构建良好的国家安全环境提供战略储备与智力支持.     

The crisis of American military assistance: strategic dithering and Fabergé Egg armies

ABSTRACT

The United States has provided substantial amounts of military assistance and aid since the end of World War Two. During the Cold War, it proved vital in protecting numerous regimes from communist takeovers. Successful outcomes occurred when American leaders made large initial aid commitments, and the states had the capacity and political willpower to use it effectively. However, Vietnam was an example of how U.S. support lagged, as leaders in Saigon preferred political survival instead of creating regime legitimacy. Following 9/11, American security aid focused on making weak countries develop stronger security forces. Unfortunately, this created Fabergé egg militaries: expensive and easily broken by insurgents. This article suggests long-term strategic commitments need to be made alongside more resources for the American State Department and similar organizations to focus on the politics of state-building. Finally, this article suggests strategies, such as “whole-of-government” approaches, to improve long-term security and political institution building.     

基于0-1分辨矩阵的集群探测盲区判定

针对航空集群协同反隐身探测盲区的识别判定问题,在多种编队构型下的集群协同探测仿真结果的基础上,运用属性的0-1分辨矩阵方法进行识别,对于连通的区域,建立相关模型,求得允许目标通过的最小宽度,将建立的模型应用到模拟作战中,仿真结果验证模型的正确性和合理性。结论表明,航空集群协同横向探测盲区可视为探测区下的保护区;纵向探测盲区则视为连通区域;斜探测盲区的判定,则依据通道倾斜角、通道长度和宽度的比值而定。     

飞机再次出动保障活动设计方法

飞机再次出动保障活动所需时间长短对提升飞机的作战效能至关重要,针对当前在飞机保障资源有限约束条件下,再次出动保障活动工期最短难以实现的难题,提出了基于分支切割法的再次出动保障活动时间优化方法。该方法以飞机再次出动保障活动所需时间最短为目标,以有限的保障人员和保障作业间逻辑关系为约束条件,可计算出时间最短的飞机再次出动保障活动具体流程,并用VB6.0编制成计算机程序,开发了飞机再次出动保障活动分析系统。最后,对某型飞机真实保障活动进行了实例分析,结果表明,使用该方法计算得到的结果准确、可靠,与实际保障情况相符,可为飞机再次出动保障与决策提供指导,提升保障活动的自动化水平,具有很好的工程应用价值。     

无人机配载弹射式导弹静稳定性分析

通过刚体飞行六自由度动力学方程建立弹射式导弹初始段无控飞行模型,并结合弹射装置动力模型和导弹发动机推力模型进行仿真计算。基于无控飞行模型和仿真结果分析了无人机配载弹射式导弹发射特性,在导弹初始飞行段对机弹分离安全性和导弹姿态控制要求进行了研究。对导弹不同静稳定度下的运动特性对比分析,分别给出了满足各种安全和控制要求的导弹静稳定度范围。进一步综合所有安全和姿态控制要求,得到了满足所有要求的最佳静稳定度。经过一个实例的仿真研究,结果表明建立的模型与所用到的方法是合理有效的。
