航母编队航渡过程中预警机阵位确定方法研究   总被引:16,自引:2,他引:14  
提供了一种航母编队航渡过程中预警机的阵位确定方法。通过对航母编队防空区域划分与防空作战过程的分析,总结了航母编队航渡过程中预警机阵位确定的原则,建立了预警机阵位的数学模型,仿真计算了模型中各个参数对预警机前出距离的影响。这些模型可用于确定预警机的前出距离、方位和高度,满足航母编队作战使用的需要。  相似文献

ABSTRACT

There have been over 90,000 UN peacekeepers deployed around the world to 78 peacekeeping operations (PKOs) in over 125 countries since 1948. Some scholars have made the case that these missions have had a positive impact on the relationship between the military and the civilians they work for. However, other scholars have identified a negative impact on civil military relations (CMR). This paper contributes to this debate by investigating how peacekeeping has impacted civil-military relations in Latin America's most prolific contributor to peacekeeping: Uruguay. This paper finds that PKOs in Uruguay have facilitated post-transitions attempts by civilians to build first-generation control, but not second-generation control. Further, PKOs have marginally improved military effectiveness, but we find that they do not improve societal trust in the armed forces.  相似文献

ABSTRACT

While most contemporary analyses of South Asian nuclear dynamics acknowledge the presence of a strategic triangle between the region’s three nuclear players, the primary focus usually remains on the rivalry between India and Pakistan. Discussions of Sino-Indian relations remain limited. This is likely attributed to the stability in the two countries’ relations, yet it is worth asking why this stability exists and whether it is likely to continue in the future. Although China and India have an acrimonious relationship, their asymmetric nuclear capabilities and threat perceptions mitigate the danger of a traditional security dilemma. India may perceive China’s nuclear aggrandizement to be a security threat, but the same is not true of China, which has a vastly superior nuclear force and is largely shaping its nuclear-force structure in response to the threat it perceives from the United States. This dynamic makes a serious conventional or nuclear conflict highly unlikely.  相似文献

ABSTRACT

The paper’s goal is to analyses the potential of the Iranian defence industry, including both research-and-development and production capabilities. It is argued that, despite official statements about the great power and sophistication of the Iranian defence industry, in reality its capabilities are very limited and cannot meet the operational needs of the Iranian armed forces. At the same time, it is argued that many official releases, which are abundantly available in the Iranian press and often unthinkingly repeated by the Western media, do not present the real and value of military products, but are rather a tool for deception and propaganda.  相似文献

ABSTRACT

Grouping warships for combat has evolved greatly over the centuries. In the early 1940s, the United States Navy began to group its warships for combat in much more flexible task forces than the previous single-type-of-warship formations. This system has evolved and spread to naval forces ashore but remains fundamentally unchanged. It now covers numbers between 1 to over 1000, of which the most prominent is the first 100 or so which U.S. Navy combat forces use. The numbered fleets worldwide utilize the series covering 20-79; 1-19 and 90-99 appear to be reserved for special allocations and Commander, Pacific Fleet; numbers over 80 to the Atlantic; 100-119 for Northern Europe and briefly Tenth Fleet; the 120 series for Second Fleet as a Joint Task Force leader; the 150 series for Naval Forces Central Command; and the 180 series for Atlantic Fleet and now-Fleet Forces Command.  相似文献

ABSTRACT

The United States’ global strategic outlook has shifted markedly since the end of major combat operations in Iraq and Afghanistan. As the United States’ strategic posture shifts, the nature of military operations is simultaneously changing rapidly. Many analysts predict that cyber-operations, autonomous weapons systems, artificial intelligence, and clandestine special forces operations will be central features in future conflicts. Although often overlooked by scholars and policy analysts, defence contractors are integral to the development and implementation of these emerging categories of warfare. This inquiry examines the evolving nature of the American defence industry and the roles corporations play in current theatres of conflict. Surprisingly, rather than becoming less reliant on defence contractors after their much-maligned performance in the wars in Iraq and Afghanistan, American military and intelligence agencies have become more dependent on the private sector as technology becomes increasingly central to warfare.  相似文献

ABSTRACT

The aim of the current study is to discuss which particular factors Russia considers as sufficient deterrent capabilities and whether the national defence models implemented in the Baltic countries have the potential to deter Russia's military planners and political leadership. Whilst the existing conventional reserves of NATO are sizeable, secure, and rapid, deployment is still a critical variable in case of a conflict in the Baltic countries because of the limited range of safe transportation options. However, whilst the Baltic States are developing their capabilities according to the priorities defined by NATO in 2010; which were updated after the invasion of Crimea in 2014, Russian military planners have meanwhile redesigned both their military doctrine and military forces, learning from the experience of the Russo-Georgian war, the Russia-Ukraine conflict, and other recent confrontations. Accordingly, there is a risk that the efforts of the Baltic countries could prove rather inefficient in deterring Russia.  相似文献

ABSTRACT

Bagayoko, Hutchful, and Luckham correctly argue that the structures, characteristics, and operating methods of official security institutions in Africa have been somewhat neglected, with a lack of much recent research. The Somali National Army (SNA) sits among these lacunae. Its formal structures can be used as a skeletal starting point and springboard to start to draw the network diagrams that chart informal linkages. This is why recent declassification decisions by U.S. intelligence bodies, coupled with period documents released to the UK National Archives, hold significance in helping us understand early hierarchical SNA arrangements. They show the steady build-up in size of the force, to 1987, to about the time the civil war began to fragment the state.  相似文献

ABSTRACT

Over a decade of security force assistance (SFA) initiatives to build an effective Somali National Army (SNA) failed because of the interrelated effects of political, contextual and operational challenges. The key political challenges were interest asymmetry between international actors and Somali elites, insufficient focus on institution-building and a lack of donor coordination. The principal contextual challenges in Somalia were the legacies of two decades of state collapse and the negative effects of clan dynamics. The main operational challenges were building an army while simultaneously fighting a war, the complexities of military integration, and the severe capability gaps afflicting the SNA.  相似文献
