越肩发射的研究现状和发展

越肩发射就是本机利用机载火控系统控制机载空空导弹攻击尾后敌机的一种新型的攻击方式。越肩发射分为两种发射方式:一种是导弹向前发射,在空中转弯,然后去攻击后方的目标,叫做前射;另一种是导弹直接向后发射,去攻击后方的目标,叫做“后射”,也叫“后向攻击”。从1993年越肩发射被公开报道,并引起人们的注意,至今已经11年。国内外越肩发射的研究已经取得了很多成果。介绍了目前各国越肩发射的发展情况,重点评述了各种越肩发射的实现方法,总结了目前三个研究方向的工作,即前射、后射和工程化,认为越肩发射会在导弹控制、制导律和火控系统三个方面展开工作,并展望了越肩发射研究工作的未来。     

Defence industrial policy – a sound security strategy or an economic fallacy?

This article explores whether it makes sense for national governments to employ defence industrial policies – such as offsets and discriminatory procurement practices – to support their domestic defence industries. This question has so far primarily been discussed by economists, who have argued strongly against the use of defence industrial policies. This article maintains that these economists fail to address the often complex motivation behind the introduction of these policies. It illustrates these shortcomings by contrasting their arguments against a case study of Norway, which accounts for the country’s use of defence industrial polices from the early post-Second World War era up until today. The article concludes that, depending on their objectives, defence industrial policies can be seen as either a sound security strategy or an economic fallacy.     

European defence industry consolidation and domestic procurement bias

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.     

Counterinsurgency in Vietnam – schizophrenia until too late

ABSTRACT

Insurgencies remain political projects, and thus the American experience in Vietnam remains relevant in any search for approaches. A population-first strategy – with tactics compatible with protecting people and winning their willing support – is essential, as much for success in local pacification as in retaining support in the homeland which has deployed its personnel abroad to assist another state. In the actual area of operations, decentralization of effort is required to get as close as possible to the population base being targeted by the insurgents. This remains essential for all mobilization in support of a polity, regardless of the extent to which insurgent challenge is grounded in grievances or simply based on coercive power.

Women combatants and the liberation movements in South Africa

This article examines women's role as combatants in national liberation forces in South Africa. Three categories – guerrilla girls, combative mothers and the in-betweeners – are introduced to underscore the varied ways in which women have participated in combat within the national liberation movements. Factors such as age and one's ability to leave the country affected whether women could participate in combat as ‘guerrilla girls’ or if it limited them to fighting apartheid violence from home, or if there were women who can be defined as having fallen somewhere in between these categories. These categories are used to theorise women's combat roles in the anti-apartheid struggle, thus broadening and challenging the dominant notions of combat that often hide women's contributions in war. In this regard, different periods of struggle, physical location, as well as age, determined the methods of activism available to men and women.     

A ‘transparent gold’ rush?

Abstract

The signing of a new treaty on the equitable sharing of the Nile waters – signed last May in Kampala by Rwanda, Ethiopia, Uganda and Tanzania – has the potential of derailing relations with Sudan and Egypt. According to the latter countries, this new agreement replaces the 1959 Nile agreement – that awarded them with 90 per cent control over the Nile water – giving other Nile Basin countries the possibility to implement water-related projects in agriculture and energy. This new development, according to Egypt and Sudan, places their water level security in jeopardy. Furthermore, the use of land grabs and water consumption for food security by wealthy foreign countries contributes to the sensitive situation the nine Nile Basin countries are now facing. Water is a red line when it comes to Egypt and Sudan and the future of the whole region depends on whether this line will be crossed.     

Aligning national “logics” in a European military helicopter program

This article analyzes the public side of the NH90 network consisting of four participating countries (Germany, France, Italy, and the Netherlands) and their industrial partners. Comparable to observations in earlier international projects in the defense sector, the development and production of the NH90 defense helicopter did not match original plans and costs estimates. On the basis of four mechanisms that were intended to facilitate the cooperation between the partnering countries (the General Memorandum of Understanding; coalition formation; the role of the central agency; and the process of vertical escalation) the question is posed whether or not there was a true alignment of national interests and “logics.” The lack of standardization, as well as program delays and issues concerning the division of the work-share, lead to the emerging alignment being characterized as “quasi-alignment” at best.

Military Maladaptation: Counterinsurgency and the Politics of Failure

Tactical learning is critical to battlefield success, especially in a counterinsurgency. This article tests the existing model of military adaption against a ‘most-likely’ case: the British Army’s counterinsurgency in the Southern Cameroons (1960–61). Despite meeting all preconditions thought to enable adaptation – decentralization, leadership turnover, supportive leadership, poor organizational memory, feedback loops, and a clear threat – the British still failed to adapt. Archival evidence suggests politicians subverted bottom-up adaptation, because winning came at too high a price in terms of Britain’s broader strategic imperatives. Our finding identifies an important gap in the extant adaptation literature: it ignores politics.     

An Exploratory Study of the Decision to Refrain from Killing in the Accounts of Military and Police Personnel

Although previous studies have examined killing as an outcome-oriented measure, few have explored non-killing as a socially organized process. Using letters written by soldiers, police officers, and security professionals found in the magazine Soldier of Fortune, this study examines cases in which they refrain from killing their opponents. Our results indicate that refrained killings by these actors are socially organized in ways that are shaped by situational, environmental, technological, administrative, and moral factors. In addition, it was found that when police officers and soldiers realized the humanity of their opponents, they employed alternative methods to subdue or control without using lethal force, despite situational and legal justifications for doing so. Implications for the sociology, psychology, and ethics of killing – or not killing – are discussed.     

Quarrelsome committees in US defense acquisition: the KC-X case

When the US Air Force set out to acquire a new aerial tanker (the KC-X), two highly suitable alternatives were offered. What could have been a short and simple source selection turned into a prolonged embarrassment. The original selection of 100 leased KC-767s was made in May 2003. But the KC-46 is expected to be operational in 2017 – more than a decade later. Our primary purpose here is to narrate and explain key events in the KC-X program. We search for useful paradigms, based in part on the US Government being better viewed as a quarrelsome committee than a monopsonist. In addition, we consider what this case might tell us about the US defense acquisition system.     

Regina Maris and the Command of the Sea: The Sixteenth Century Origins of Modern Maritime Strategy

The concept of the command of the sea has its roots in medieval notions of the sovereignty of coastal waters, as claimed by several monarchs and polities of Europe. In the sixteenth century, a surge of intellectual creativity, especially in Elizabethan England, fused this notion with the Thucydidean term ‘thalassocracy’ – the rule of the sea. In the light of the explorations of the oceans, this led to a new conceptualisation of naval warfare, developed in theory and then put into practice. This falsifies the mistaken but widespread assumption that there was no significant writing on naval strategy before the nineteenth century.

Rebel movements in the DRC

Despite a generally valiant effort on the part of the United Nations (UN) since 1999 to bring peace and stability to the Democratic Republic of the Congo (DRC), the country continues to be destabilised by rebel forces. These armed movements pose a constant threat to the fragile transition in the DRC, and security in the country is continuously undermined. This article examines rebel forces in the DRC from two perspectives. Firstly, it examines such movements as a manifestation of sub-national terrorism. Secondly, it examines armed movements from the perspective of so-called ‘ungoverned spaces’. The view taken in this article supports the scholarly insight and argument that in countries such as the DRC, armed movements and militias are filling power vacuums that are the result of the inability and lack of military capacity of weak states to fight these movements effectively. Specifically, the eastern and north-eastern parts of the DRC have been major conflict zones where sub-national terrorists employ terror as a strategy. In this context, the DRC is severely affected by terrorism – a phenomenon in the DRC that is intimately linked to the failure to effect sustained development and to consolidate accountable and effective governance.

Supply chain coordination with shelf‐space and retail price dependent demand and heterogeneous retailers

We consider supply chain coordination in which a manufacturer supplies some product to multiple heterogeneous retailers and wishes to coordinate the supply chain via wholesale price and holding cost subsidy. The retail price is either exogenous or endogenous. The market demand is described by the market share attraction model based on all retailers'shelf‐spaces and retail prices. We obtain optimal solutions for the centralized supply chain, where the optimal retail pricing is a modified version of the well‐known cost plus pricing strategy. We further get feasible contracts for the manufacturer to coordinate the hybrid and decentralized supply chains. The manufacturer can allocate the total profit free to himself and the retail market via the wholesale price when the retail price is exogenous, but otherwise he cannot. Finally, we point out that different characteristics of the retail market are due to different powers of the manufacturer, and the more power the manufacturer has, the simpler the contract to coordinate the chain will be. © 2010 Wiley Periodicals, Inc.

The poverty of power in military power: how collective power could benefit strategic studies

Strategic studies deals intimately with the topic of power. Most scholars in the discipline work with a concept of power as an adversarial zero-sum competition. This is natural and necessary. However, other conceptions of power developed within political science and sociology could enrich strategic studies. Approaching two typical, traditional tasks of strategy – alliance building and war-fighting – this article demonstrates the heuristic mileage of theories of collective power. In particular, we can shed new light on the post-Cold War transformation of NATO as well as state-building as a strategy in counter-insurgencies with new ideas of power. Broadening the palette of theories of power is thus valuable if strategic studies is to prosper as an independent field of study.
