So a few months ago we were discussing hypersonic weapons, and whether the US is actually lagging behind on the tech.

This video argues that not only are we not behind, but we may be more advanced than Russia and, less likely, China.
https://www.sandboxx.us/blog/hypers...-difference-between-boost-glide-and-scramjet/ - same guy with a 3 month old article explaining the functions and differences between the various hypersonic technologies utilized.
No one else has even test fired the scramjet style, which would deliver said cruise missile faster and wouldn't require
any ballistic trajectory to get to hypersonic speeds. The Russian and Chinese styles use "boost glide" or "boost to glide" concepts to shoot the missile way up high and then effectively let gravity do its thing to achieve the mach 5+ speeds. The American scramjet concept uses a rocket to get to speed at much lower altitudes and then turns constant propulsion over to the scramjet. Really the only difference between a traditional ICBM or air-launched ballistic missile and Russia's Kinzhal is the use of guidance and gliding. It's literally a re-build Iskandar-M, which has been in service since 2006 and itself based on older ground-launch designs. So they slapped a better guidance and slightly improved propulsion system onto an existing weapon, and called it revolutionary. I know Russia claims to be almost ready with their 3M22 Zircon, but it's likely still years from being operational (if ever). Russian military announcements only lie when they say anything, so until one of these actually is seen in the wild, treat it like the SU-57 (still not operational despite being flown everywhere) and SU-75 (announced but still only a wooden model mock-up) or the MIG-41 (still on paper only) and dismiss it for now.
The Chinese are a good bit more advanced with their hypersonic glide missiles (DF-17), and this could pose a serious threat to our carriers, but Russia seems to lag a good bit behind them.
For now, Russian operational hypersonic missiles are just faster cruise missiles that use ballistic/glide routes. We need to stop scaring ourselves and make sure we don't have another
missile gap situation.
