- 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
You don’t need to launch the missile from the same point as the detector, you can launch closer to the aircraft. And the b21 is a sub sonic bomber, probably flying about mach 0.8 or so. Even if you needed a lot more missile locations for non hypersonic missiles, it’d still be orders of magnitude cheaper. Seems like carrier groups are about the only target valuable enough to spend a hypersonic on.
