美国国防部新闻网站2月27日讯，在美空军协会线上举办的航空航天战研讨会上，国防部研究与工程副部长办公室高超声速主管麦克怀特透露，国防部已完成了高超声速现代化战略的拟制，随之转型作战能力的研发与交付进程将加快。该战略主要包括：发展陆海空平台发射的高超声速打击武器，常规弹头，生存力高、射程远、快速响应，可打击海上、海岸、内陆等战术战场高价值和时敏目标。反高超声速采用多层综合防御体制，以拦截敌人战术型高超声速导弹。利用可重复使用高超声速系统遂行情报、监视、侦察和打击任务，以及快速进入空间的第一级助推火箭。

Defense Officials Outline Hypersonics Development Strategy

FEB. 27, 2021 | BY DAVID VERGUN,  DOD NEWS

The Defense Department has identified hypersonics as one of the highest priority modernization areas, as Russia and China develop their own capable systems.

Hypersonic systems are able to travel on extended flights within the upper atmosphere — 80,000 to 200,000 feet — at speeds near and above Mach 5, and they’re able to maneuver in ways that are hard for defenders to predict.

The high-altitude range creates a gap between air defenses and ballistic missile defenses, Mike White, principal director for hypersonics in the office of the undersecretary of defense for research and engineering, said.

White told attendees of the Air Force Association’s virtual Aerospace Warfare Symposium that to address these challenges, the department has developed a hypersonics modernization strategy that accelerates the development and delivery of transformational warfighting capabilities.
