It was reported in the news media that Russia had already used a hypersonic arrow in Ukraine and Russian troops aligned with it and claimed to direct something like ammunition or something like that by Ukrainian troops.
The hypersonic arrow travels at over 3.3 Km / sec, can roam the radar systems and at that speed no rocket can drop it. So it is also a game changer when the target appears to be similar to ducks sitting due to the speed of an arrow and perhaps the number of explosives it can carry, including nuclear war heads.
China one thing has the technology and ability to use hypersonic arrows while the UK is in the process of developing it while the US may already have it because its Hypersonic development is being blocked.
US bureaucracy if not political.
It is alarming when Russia already has a hypersonic arrow and China because these two countries are both oppressive countries and may get high on when a major conflict occurs that threatens the freedom of everyone in the world.
I do not see a known system that can withstand a hypersonic arrow that enters due to its displacement and speed almost ten times the speed of sound. So you would think that such a fast-moving weapon destroys an area beyond termites and possibly knocks the government out of its target because it is an accurate type of arrow that can destroy important targets in a dangerous, defenseless world.
So the Ukrainian war is not sure to stop especially now as Putin uses a variety of high-tech weapons that could destroy the world as we know it and restore humanity back to the stone age because during the stone age at least their offspring will not give birth to abnormal offspring, genetic mutations , or even cancer but after the possible destruction of nuclear weapons I think we will never get a chance to live our normal lives again.
Sounds like a science fiction novel but hypersonic arrows are very real, actually used by Putin a few days ago for the wrong reasons like his invasion of Ukraine. I just hope there is also a high-tech system for hypersonic missile deterrence otherwise even the most powerful nations seem like an empty world when the time comes when it will come to their territories.
