随着美国内外部环境和空间安全观的转变，美国军事航天发展战略出现了重大调整，从注重提升卫星系统功能向注重强对抗条件下如何提升体系的防护能力、保障体系功能转变。本文通过论述美国空间安全观的变化、美国军事航天分散体系转型战略的目的意图、转型途径，从顶层规划、体系评价指标和面临的主要困难等方面，对军事航天转型进行了分析，探讨了现阶段转型战略在美国军用通信、导弹预警、侦察、气象、导航等领域的初步实施情况及其方式和难度。
With the change of the internal and external environments and the space security concept, the US military space strategy undergoes major adjustments, from emphasis on improving the satellite system function to focus on how to improve the protective abilities of the space architectures and how to secure the functions of space architectures under the adverse conditions. This paper traces the change of the US space security concept also the purpose and the method of the strategy transformation to a disaggregated military space architecture. The strategy transformation is analyzed from various aspects such as the top level planning, the evaluation indexes of the architecture and the main difficulties. The implementation statues, the methods and the difficulties of the strategy transition in the fileds of the military communication, the missile warning, the reconnaissance, the meteorology and the navigation satellite systems are analyzed.
