Russia has a history of announcing weapon systems for propaganda purposes, and then it turns out they're mostly on paper, half done or of low quality. That doesn't mean this is the case here, but they do have a history of over promising and under delivering. The reality is that Russia's conventional or "normal" ICBM weapons are far more of a threat to the US than any hypersonic platforms. The Chinese are the ones to watch. They have been much more thoughtful about their hypersonic weapons development and are trying to develop tactical hypersonic weapons in addition to strategic assets.
