三道防线是防空领域的重大军事变革

当前国土防空和舰队防空中,面临的空袭特点是空袭体系从防区外和视线外对防空体系所保卫的地(水)面目标实施饱和攻击。为了对抗这样的空袭战术,防空体系必须从以投弹圈为唯一防线的作战模式中解放出来,向远程打击预警机,中程拦截空袭武器载机和近程防御空袭武器的三道防线转变。这一转变牵动了防空体系和防空导弹的发展方向,因此是防空领域的一次重大军事变革。

“Government contracting options: A model and application“∗

This paper models and simulates a government‐contractor principal‐agent weapon system repair model. Insights are derived as to how government repair contracts should be constructed so as to induce optimal contractor behavior. The paper's general conclusion is that the best contracting approach combines a lump‐sum payment that does not vary with the number of units repaired, expensive item cost‐sharing, and a contractor‐provided availability guarantee. Provided there is intercontractor competition, this type of contract performs well even if the government is poorly informed about weapon system break patterns or repair costs.     

基于排队论的地面防空系统服务概率研究

排队理论计算地面防空系统的服务(可射击)概率时,因计算模型的制约,可能使计算结果大于实际结果,影响防空兵指挥员指挥决策的准确性。对此,根据地面防空系统的主要特征,分析了引起计算误差的因素和误差的可能取值范围,克服了排队论模型的局限性,为计算结果的修正提供了依据。

Mimetic and normative isomorphism in the establishment and maintenance of independent air forces

Why do countries have air forces? Organizational alternatives, such as maintaining separate air arms for the army and navy, have become quite rare. The conventional narrative advanced by advocates of independent air forces stress that the primacy of airpower in modern warfare mandates centralized control of most military aviation. In this view, political–military uncertainty has driven mimetic isomorphism – pressure on national governments to organize as others organize so as to fight or deter war just as effectively. However, working from a set of 56 countries that were politically independent within a few years of the establishment of the first ever independent air force (the Royal Air Force) in 1918, and continuing through nearly the present, there is no clear pattern of external military pressure prompting this particular reorganization. Rather, from anecdotal evidence, the cause has more likely been normative isomorphism – a professional craving to look as others look to foster political or personal legitimacy. For whatever reason, though, choices of structures tend to lead to specific choices of policies. Thus, the result suggests that defense ministries looking for more effective or less costly organizational schemas may reasonably consider alternatives to the tripartite army–navy–air force structure.
