US intelligence learned about the problems in developing the hypersonic Avangard

Russia cannot find a reliable source for the production of important components from hydrocarbon fiber for the Avangrad hypersonic missile. This is reported by the portal CNBC, citing sources familiar with the US intelligence report.
According to their data, the case of a hypersonic device does not withstand heating when re-entering the dense layers of the atmosphere, which is why internal systems stop working. "So far, we have seen more ambitious statements about success than real evidence of this," said Pentagon spokesman Eric Paehon.
According to CNBC, intelligence obtained by the information contradicts the statements of the Russian authorities about the beginning of the mass production of hypersonic weapons. However, this program is a priority for Russia and can still be completed by 2020, according to sources of the publication.
About Avangard told Russian President Vladimir Putin March 1, 2018 during a message to the Federal Assembly. According to the head of state, the complex is able to fly at a speed of 20 times higher than the speed of sound, while “it goes to the target, like a meteorite, like a fireball, the temperature on the surface of the product is 1600-2000 degrees Celsius”, and “the winged unit with this is reliably controlled. ”
Later, the Ministry of Defense announced the conclusion of a contract for the mass production of the first batch of hypersonic missiles.
