B-21成功首飞,载荷和尺寸“缩水”说明了美军何种战略需求?

from 看航空早读|竖耳朵!来听航空新鲜事儿

B-21成功首飞,载荷和尺寸“缩水”说明了美军何种战略需求?无论是此前美国公开的信息,还是首飞中曝光的真机照片,都证实了相较于B-2,B-21在尺寸、重量级别和发动机数量上都有所“缩水”。 如何理解B-21在尺寸重量方面相关的总体规划,特别是载荷航程能力?这是一个富有争议的话题,特别是在相关公开信息极少的背景下。一些人认为,B-21这样设计是以大幅牺牲战略打击能力为代价,以获取更低的采购和运营费用,其真实定位向中程战轰的定位进行了降级,是美国军事实力衰落、其财力无力继续原有战略打击能力的体现。B-21是B-2的继任者,如果要试图正确理解B-21的设计意图,也就是说如何在B-2的基础上进一步发展、扬长避短,那么首先就要理解美军视角下B-2的优缺点。
