A Roskosmos facility called TsNIIMash are under suspicion for leaking information of hypersonic missile secrets to Western spies. Last week, the Russia defense ministry released video of two new hypersonic missile systems – called Kinzhal and Avangard.
The US will not make hypersonic missiles using the simple and relatively ineffective brute-force Russian approach. The US would benefit from knowing the exact specifications and capabilities of Russia’s missiles for anti-missile systems.
Kinzhal is a short-range Iskander missile attached to a plane. It does not have a detachable warhead, and the probability of it disintegrating on re-entry into the atmosphere is much higher. It cannot hit moving targets. The targeting data has to be put into the missile before launch.
The Avangard gliding warhead is a re-entry vehicle designed to perform erratic hypersonic manoeuvres to baffle defence systems. But that design increases the risk of it disintegrating and it loses accuracy.
