HMM: The Kremlin reportedly accused three hypersonic missile scientists of treason.

Employees of the Institute of Theoretical and Applied Mathematics of the Siberian Branch of the Russian Academy of Science published an open letter on May 15 in defense of three of their scientists — Anatoly Maslov, Alexander Shiplyuk, and Valery Zvegintsev — whom Russian authorities reportedly arrested in the past year under suspicion of committing “high treason.”[10] The open letter also noted that these arrests deter the younger generation from pursuing careers in science, which contributes to a decrease in the quality of scientific research. Kremlin Spokesperson Dmitry Peskov claimed that the Kremlin was aware of the open letter and that Russian security services are involved.

Russia’s “unstoppable” hypersonic Kinzhal missiles — which aren’t even hypersonic as properly understood — have underperformed so far.
