The Kh-47M2 Kinzhal (Russian: Х-47М2 Кинжал, lit. ‘Dagger’; NATO reporting name: AS-24 Killjoy) is a Russian hypersonic air-launched ballistic missile.[4][5] It has an estimated range of 460–480 km (290–300 mi)[6] and a reported top speed of Mach 10.[
Mebe because they move so fast your eyes cannot track them....
Does not compute
MACH 10 = 7,000+ mph yet this device only has a range of 300 miles? If fired up for only 10 seconds its range would be well over 700 miles.
Copy and paste from wikipedia... “Wikipedia does not consider itself credible because anyone can edit it at any time, any information it contains at a particular time could be vandalism, a work in progress, or just plain wrong.”
Do research, it’s a 1980s rocket with a booster capable of hypersonic speed. It’s a modified version of the ground-launched 9K720 Iskander.
All ICBMs are hypersonic so was the space shuttle which I watched often.
The video posted showed nothing.
