Maintenance and flight scheduling of low observable aircraft

In this article, we focus on relatively new maintenance and operational scheduling challenges that are faced by the United States Air Force concerning low‐observable (LO) or stealth aircraft. The LO capabilities of an aircraft degrade stochastically as it flies, making it difficult to make maintenance scheduling decisions. Maintainers can address these damages, but must decide, which aircraft should be put into maintenance, and for how long. Using data obtained from an active duty Air Force F‐22 wing and interviews with Air Force maintainers and program specialists, we model this problem as a generalization of the well‐known restless multiarmed bandit superprocess. Specifically, we use an extension of the traditional model to allow for actions that require varying lengths of time, and generate two separate index policies from a single model; one for maintenance actions and one for the flying action. These index policies allow maintenance schedulers to intuitively, quickly, and effectively rank a fleet of aircraft based on each aircraft's LO status and decide, which aircraft should enter into LO maintenance and for how long, and which aircraft should be used to satisfy daily sortie requirements. Finally, we present extensive data‐driven, detailed simulation results, where we compare the performance of the index policies against policies currently used by the Air Force, as well as some other possible more naive heuristics. The results indicate that the index policies significantly outperform existing policies in terms of fully mission capable (FMC) rates. In particular, the experiments highlight the importance of coordinated maintenance and flying decisions. © 2015 Wiley Periodicals, Inc. 62:60–80, 2015     

Polaris,East of Suez: British Plans for a Nuclear Force in the Indo-Pacific, 1964–1968

This article investigates the little-known plans formulated by Harold Wilson's Labour government to deploy Polaris submarines in the Indo-Pacific region. The scheme was first proposed in 1965 as a response to several problems faced by British policy-makers, including China's acquisition of a nuclear capability, Britain's wish to maintain a meaningful position ‘East of Suez’ at reduced cost, and German pressure for equal treatment within NATO on nuclear matters. Despite extensive high-level discussion, the plans were finally abandoned in mid-1968, as Labour moved more decisively to forsake the world role.     

Theorist of Maritime Strategy: Sir Julian Corbett and his Contribution to Military and Naval Thought

The Volkssturm (People's Storm or Home Guard) was formed by the Nazi Party in late 1944 as Allied forces closed in on the Reich from the east and west. The political ambitions of Martin Bormann, Hitler's secretary and the head of the Nazi Party Chancellery, were the driving force for this new national organisation. Lacking resources, the Volkssturm's military value was negligible even in eastern Germany where battalions occasionally fought with great tenacity against the Red Army. However, its foundations, character and nature were indicative of the process through which Party power had reached its zenith on the eve of the Third Reich's collapse.     

The road not taken: Conflict termination and guerrillaism in the American Civil War

Irrespective our views on the rationality of our opponent's continuing to conduct operations against us, unless utterly extirpated, he retains a vote on when and how conflict will end. This is because war is about power — compelling another actor to do something he would not otherwise do, or to cease doing something he would otherwise prefer to do. In planning for conflict termination we should account for the peculiarities of opponents who may decide not to quit when we have beat them fair and square. We do not desire that they cease conventional fighting, but that they cease fighting altogether.     

Asymmetrical Indian and Chinese threat perceptions

India tends to be deeply apprehensive of threats from China, while China appears comparatively unconcerned about threats from India, and finds it difficult to understand why India might perceive China as a threat. Two explanations of this asymmetry are (1) a deliberate and systematic understatement of Chinese concerns about India, resulting from the mobilization function of China's public media, and (2) the greater effectiveness of China's application of power over the past 50 years.     

Storming to partition: Croatia,the United States,and Krajina in the Yugoslav War

To many scholars and policymakers, ‘partition’ offers the most efficacious means of resolving ethnic-civil wars. Others reject partition as a solution, citing flaws (both logical and empirical) and harmful international implications should such an approach become commonplace. What has been missing from this debate is an understanding of how the process of partition unfolds. In this article we examine such a process, the case of the Krajina in the war in Yugoslavia, 1994–1995. The US aligned itself with Croatia against Serbs rebelling in the Krajina region of Croatia. The culmination of this alignment occurred in August 1995 when Croatian forces initiated ‘Operation Storm’ (Oluja) against Croatian Serb insurgents. Croatian forces effectively cleansed the Krajina of its Serbian population. Eager to initiate a diplomatic peace process, Washington welcomed the Croatian operation, and largely because of Operation Storm, negotiations at Dayton became possible.
