This article reappraises the two most-studied country cases of military outsourcing: the USA and the UK. It argues that the contemporary wave of military contracting stretches back to the beginning of the cold war and not only to the demobilisation of armies in the 1990s or the neoliberal reforms introduced since the 1980s. It traces the political, technological and ideational developments that laid the groundwork for these reforms and practices since the early cold war and account for its endurance today. Importantly, it argues that a persistent gap between strategic objectives and resources, i.e. the challenge to reconcile ends and means, is an underlying driver of military contracting in both countries. Contemporary contracting is thus most closely tied to military support functions in support of wider foreign and defence political objectives. Security services in either state may not have been outsourced so swiftly, if at all, without decades of experience in outsourcing military logistics functions and the resultant vehicles, processes and familiarities with public-private partnerships. The article thus provides a wider and deeper understanding of the drivers of contractualisation, thereby improving our understanding of both its historical trajectory and the determinants of its present and potential futures. 相似文献

How have European cross-border defence industrial mergers and acquisitions affected domestic procurement bias among the major EU powers? This article departs from the findings of Andrew Moravcsik more than two decades ago suggesting that major West European states had no ingrained preferences for defence industrial autarchy. When cross-national armament projects were derailed, this could be attributed to political efforts of national defence industrial champions favouring purely domestic projects. As former national champions join pan-European defence groups, their preferences are likely modified. Does this shift procurement towards non-European “off-the-shelf” solutions which, according to Moravcsik, are favoured by defence departments? Or does it give impetus to a stronger preference for European as opposed to domestic systems? In this article, procurement patterns in the aftermath of cross-border defence industry consolidation will be analysed. Procurement bias is assessed in two industry segments characterised by pervasive consolidation. 相似文献

This survey article deals with defence spending in West Germany from 1960 on, and the resulting manpower levels and major weapons of the Federal Armed forces, focusing on macro‐economic aspects. Statistics compiled from a variety of published and unpublished sources are presented in 16 tables. An econometric defence‐spending function is derived for the period. For comparison, the equivalent data of East Germany from the last years is also presented. The small set of developments in the next few years that can be predicted firmly are discussed. 相似文献

This paper provides a methodology for estimating the economic impact of defence spending at a sub‐regional level. It does so by calculating the income and employment generated by Britain’s Royal Navy and associated defence activities in the City of Portsmouth and its surrounding area, during the financial year 2003–2004. In an era of military consolidation, the paper offers an insight into the multifaceted impact of defence‐related expenditure. Hence, it presents a generic framework that could prove useful to other researchers when seeking to measure the sub‐regional impact of naval, airforce and army facilities in other national contexts. 相似文献

In 1955, the New Zealand government authorised the creation of a Special Forces unit to operate with British forces in Malaya to counter a communist-inspired guerrilla insurgency. Drawing upon the operational experiences of the New Zealand SAS largely taken from the Cold War period, and underpinned by Colin Gray's Special Forces essentials of ‘economy of force’ and ‘expansion of choice’, this article will show how New Zealand's SAS is now accepted not only as a respected and relevant part of the nation's military capability, but also empowers its political decision-makers with the confidence to take on significant, and at times difficult, strategic foreign-policy choices. 相似文献

根据舰艇防空武器拦截过程的时间连续性和拦截效果的不确定性特点,提出了智能规划和优化调度相结合的舰艇防空计划生成方法。在规划阶段,先用智能规划描述语言PDDL对舰艇防空问题进行建模;针对新的来袭目标或观察的拦截结果,利用智能规划的高效行动推理能力,快速生成可能的备选行动方案;在优化调度阶段,对已生成的备选方案的行动系列进行时间、资源冲突处理,并计算选择出当前最佳拦截方案。与现有的采用离散化处理的武器-目标分配方法相比,该规划与调度过程充分体现了拦截过程的连续性,拦截效果的不确定性,拦截过程中的武器协同,以及最佳拦截时机的选择等,更好地描述了舰艇防空的实际过程。最后,通过蒙特卡罗仿真试验,验证了算法的有效性,为舰艇的自动化防空提供了一种新的解决办法。 相似文献
