  • The new US stealth bomber may be taken by surprise by ultra-fast missiles coming from near space with the unpredictable ‘Qian Xuesen trajectory’
  • Beating the American bomber will be pivotal in any future conflict with China, as it has the potential to slip behind China’s core defence

Hypersonics don't make any sense against an airborne target. A b21 isn't going to have phalanx or anti missile missiles, so you might as well use a missile that costs 1% as much. But that's all assuming you get a perfect missile lock on the most stealthy aircraft ever, which would take an incredible confluence of bad luck and bad planning.

Why not? Aren't all modern active counter measures dependent on reaction time? And isn't there simply a lot less reaction time against a hypersonic inbound?

Hypersonic weapons go up way too high to be used on aircraft.

Is there some law of physics saying you can't target and destroy a plane from above?

From a ground launched system that requires a ballistic path to hit a agile moving target, it wouldn't be practical at Mach 6.
