Can Smart Defense work? A suggested approach to increasing risk- and burden-sharing within NATO

“Smart Defense” is NATO's new approach to risk- and burden-sharing, which has been a chronic problem within the alliance since the 1950s. Numerous solutions have been proposed, but initiatives resulting in more equitable burden-sharing have never been fully implemented. There are two driving forces influencing a county's willingness to support such initiatives – the economic theory of alliances and the risks posed by the implementation of capability sharing. The authors examine each of these and propose that rather than aiming for group consensus on the production of capabilities, NATO should focus on interoperability through support functions. This approach provides the most likely solution for connecting the forces, doctrine, procedures, standards and other factors of joint capability production such that country leaders find the risks of doing so to be politically and militarily acceptable.     

US strategic preferences in the early twenty-first century

This article investigates how US national security planners have envisioned the emerging strategic environment during the early twenty-first century and evaluates how their perceptions of this strategic environment have changed during these years. This conceptual evolution can be seen in how defense planners define threats, identify defense priorities, and design security strategies. Five key strategic planning documents serve as the basis for this analysis and illustrate significant shifts in how the US government has envisioned its own security requirements as well as the context within which its strategic vision will need to be realized. These planning documents are: (1) Joint Vision 2020, (2) the Bush Administration's 2002 National Security Strategy of the United States, (3) the Obama Administration's 2010 National Security Strategy, (4) US Strategic Defense Guidance entitled Sustaining US Global Leadership: Priorities for 21^st Century Defense, and (5) the US Chairman of the Joint Chiefs of Staff's Capstone Concept for Joint Operations: Joint Force 2020.     

The Shifting Determinants of Defense Spending Preferences Between 1980 and 2008

This paper analyzes defense spending preferences using ordered logit regression analysis of American National Election Survey data from 1980 through 2008. Our results indicate that as opposed to having the ideology of isolationism, political party identification towards the Republican Party or having economic stakes in defense spending always play a significant role in increased preference towards defense spending. Demographic groups such as Native Americans, Hispanics, and retired women, a demographic subgroup, display generally positive preferences towards defense spending. Somewhat surprisingly, another demographic subgroup, ‘security moms,’ do not show a preference. Our analysis also displays lower (higher) preference in the early 1990s (2000s) for defense spending compared to the year 2008.     

一种用于SEAD任务的改进型Voronoi图

根据雷达所在位置构造Delaunay三角形,取它的外心作为Voronoi图的顶点,构造常规Voronoi图,使用随机搜索算法可以为无人战斗机规划安全路径。由于战场环境威胁各异,使用常规Voronoi图不再能表征真实的SEAD任务,增大了无人战斗机的威胁,本文提出了一种新的Voronoi图的改进方法,以提高无人战斗机在执行SEAD任务时的生存概率。首先,根据可能出现的各种情况进行了分析,提出了改进型Voronoi图的构图原则。然后,提出了在不同威胁体下,基于"Delaunay多边形"构造改进型Voronoi图的方法。最后,进行了仿真。仿真算例的结果验证此方法可以明显地提高无人战斗机的生存概率。     

国防工程智能信息系统效能评估研究

在简要介绍国防工程智能信息系统组成和功能的基础上,提出了系统效能评估指标体系,分别用BP神经网络和AHP法建立了国防工程智能信息系统效能评估模型,并对系统的设备监控管理能力进行了评估。仿真结果表明,BP神经网络法克服了传统评估方法精度低、模型复杂和计算量大的缺点,可将以往的专家经验知识进行分析学习,能够实现实时方便的在线评估;AHP法对多层次的指标体系具有较强的处理能力,但是存在指标权重确定主观性强,计算量大的问题。

美国国防太空力量发展的动向及应对 ——基于对美国2020年《国防太空战略》的解读

发展国防太空力量是美国谋划大国竞争的战略支点。特朗普政府执政以来,为捍卫一超独霸的太空地位,加速推进太空军事化进程,已制定《国家太空战略》,签署新的太空政策指令,成立第六军种“天军”。2020年6月,美国公开最新版《国防太空战略》报告。本文对其梳理分析以研判美国国防太空力量发展动向,并运用网络调研法搜集近年美国政府部门关于国防太空力量发展的权威政策文本及知名智库的深度研究报告。在此基础上,把美国2020年最新版《国防太空战略》作为中心文本,以文献分析法归纳美国国防太空力量发展的动因、目标及行动计划。中国作为负责任的发展中太空大国,应当积极借鉴并应对美国2020年《国防太空战略》：内强素质,提升国防太空军事技术硬实力;外树形象,在国际场合积极推动太空和平利用的政策议程。
