Abstract:

Under the strategy of competition among major powers， the US military continues to promote the development and construction of hypersonic defense systems from three aspects of sensor layer， command and control， and interception weapons. Finally， this can offset the equipment advantages of hypersonic weapons and crack the anti-intervention/regional denial capabilities of opponents in “competition among major powers”. Since the US Department of Defense decided to adopt a layered defense strategy for hypersonic defense， the US military has fully relied on the existing ballistic missile defense systems. By exploring emerging technologies， developing various interception methods， and cooperating with allies， the US military builds a multi-platform early warning and detection system based on space and supplemented by ground and sea sensors. Meanwhile， a networked command and control system with real-time transmission and sky-to-earth connectivity is established. An interception system that mainly involves gliding interception and terminal interception with multiple interception methods coexisting is planned to build the theater-level hypersonic defense capability by 2034.

Key words: the United States, hypersonic defense, competition among major powers, early warning detection, gliding interception

摘要：

“大国竞争”战略下，美军从传感器层、指挥控制和拦截武器3方面持续推动高超声速防御体系的发展建设来抵消高超声速武器的装备优势，破解“大国竞争”对手反介入/区域拒止能力。自美国防部确定采取高超防御分层防御战略后，美军充分依托现有弹道导弹防御系统，通过探索运用新兴技术、发展多种拦截方式、积极与盟国合作等举措构建以天基为主、地海基传感器为辅的多平台预警探测体系，实时传输、天地联通的网络化指挥控制系统，以滑翔段拦截和末段拦截为主、多种拦截方式并存的拦截系统，计划在2034年构建战区级高超声速防御能力。
