The United States Department of Defense (DOD) is moving to up the ante on the issue of the development of hypersonic missiles, to play catch up to communist China, and Russia. It seems that both nations are way ahead of the US with these missiles. While the Russians in particular like to portray such missiles as unstoppable due to their hyper-sonic speed, it appears that while the Russian may have destroyed, or damaged a US patriot missile system with a hypersonic missile, some of these hypersonic missiles have been shot down. So, they are not invincible even with existing defences. But, still, if those hypersonic missiles had had nukes on them, it would not matter much. Clearly, these missiles are game changers, and World War III will certainly involve more such missiles than planes, which have become much more vulnerable to the deadly technology of today.
