19,030 mph = 27,910 Feet per Second. Not sure I’m buying this. I’d think a 33 ton projectile would self destruct at this speed.
Hypersonic missiles may just be a mirage. The USAF has been playing with these things for some time. We’ve learned that it’s very difficult to do; flight duration is very brief; and if they get the least bit out-of-shape aerodynamically they break up. Yet we’re supposed to believe that all our potential opponents possess operational hypersonic missiles, and we don’t. Sorry, I call B.S.
