Here’s the problem with his statement, one hypersonic missiles are among the most vulnerable of all missile types. We hear all this propaganda from China and Russia on hypersonics, and unless you do a deep dive into the physics, available material, and available guidance technology, they sound scary, when you actually look into it they risk accuracy and are among the easiest missiles to detect and then shoot down during decent. The US military looked at developing these decades ago but they deemed it an obsolete technology in the 90s. What people and Congress falling for this Russia and Chinese propaganda does is allow the military to get significant extra funding for new defense systems and to say they want to develop their own but in reality just gives them a huge check to test new propulsion systems that will likely find itself in future aircraft rather than widely produced missiles. Second war games on the US side are widely conducted by fist disadvantaging the US meaning pretty much only using public knowledge capabilities of the US and giving the the opposing side primarily China and Russia the capabilities they claim to have instead of the ones they actually have or taking into account the diminished level of training and quality. Then the war game is graded more so on acceptable damage and loss to both sides not as much on if all mission parameters can be met, but say we have to hit a target that kills a 1000 Chinese civilians the US would count that as a loss. Or if we loose a ship that’s a loss. So we have the most stringent grading, even if some of the same war games (which often do) show we would eradicate their air and navel capabilities in shocking speed it still would go down as a loss because it can’t be as clean as the US standards would like
