War Tech the US, Russia, China and India All Want: Hypersonic Weapons

An anonymous reader writes: They can hit any target in 30 minutes or less. They travel anywhere from Mach 5 to Mach 25. All the major powers want them, and many look at them as a military game changer — if only they can make them work. Are hypersonic weapons the future of military doctrine?

Hypersonic weapons — or ballistic weapons that can hit a target flying many times faster than the speed of sound — have been hyped since the 1970s. Currently almost all of the major powers are trying to build them. The U.S. and China seem to be the furthest along, and are working on various types of systems. China hopes such weapons could be a game changer and deter any U.S. actions in Asia. There is, however, one big problem (besides the insane amount of technology to make them work, considering their speed): a possible arms race that could lead to a nuclear war:

"According to some analysts, the development of hypersonic weapons creates the conditions for a new arms race, and could risk nuclear escalation. Given that the course of hypersonic research has acknowledged both of these concerns, why have several countries started testing the weapons?"

    I don't see how this can work.

    ICBMs are already hypersonic weapons. Problem is launching one gets everyone else twichy because they might have a bunch of nuclear warheads on the end.

    Whereas hypersonic missiles don't. So won't make anyone twitchy. Until someone sticks a nuclear warhead on them which is about the first thing they'll do. Then they'll make everyone just as twitchy as before except that they flight path will be a bit different.

    About 3 years after the first practical hypersonic air breathing missile comes online, they'll be in *exactly* the same place as ICBMs with similar flight times, hitting capabilities and unusuableness due to everyone else thinking you're staring WWIII.

    On the other hand, hypersonic arbreathing engines are cool, so whatever.

    Yes, it can lead to an arms race. The problem is that if you hold off and your enemy doesn't, you're a sitting duck. Avoiding the arms race is only possible if everybody involved holds off, and you don't/can't trust any of them to hold off so you have to proceed as if you're already involved in an arms race whether you want to be or not. Because the only thing worse than being in a Mexican standoff is being the one guy in a Mexican standoff without any guns.

    The basic concept of a rocket goes back to 400BC and Archytas, who built a wooden bird propelled along wires by steam.

    The basic concept of the modern jet engine was patented as a stationary turbine in 1791 working versions were built in the 1800s. Turning it into an aircraft engine was just a matter of making it smaller and lighter.

    Charles Babbage came up with the concept of the Analytical Engine in 1800s, even though he couldn't build it at the time.

    The idea of sending messages through a network of wiring comes from the telegraph, which showed up in the 1750s.

    GPS navigation is a combination of a lot of technologies; rocketry (already mentioned), radio (Marconi in the late 1800s), navigation by triangulation (celestial navigation, the whole of written history), atomic clocks (Lord Kelvin, 1800s) and so on.

    Modern day technology didn't suddenly pop into being during WWI. but rather is an evolution of older, pre-1914 technology and most of those older technologies weren't actually developed as tools of war. The human race just happens to be very good at taking any technology available and using it to kill one another.

    tl;dr - don't dis pre-1914 tech. Without it, we'd all be sitting in caves drawing crappy pictures on the walls for entertainment.

    The US doesn't have territorial ambitions on any other country. When was the last time you heard of them annexing anybody, since the Spanish American war?

    China, OTOH, has ambitions of re-annexing Taiwan and making it a part of the PRC, as opposed to ROC. Besides that, they have territorial disputes with Vietnam, Philippines, Malaysia and India. If they got these, that would only encourage them to do what others have been fearing - overrun Taiwan, the disputed South China Sea Islands and Arunachal Pradesh. There's a good reason not to want China to have these.

    The other 2? Russia, by its acts in the Donbass, has reverted to what it used to be under both the Tsars and the Soviet Commissars. India - while their adversaries - Pakistan, Bangladesh & China - are bad, India did use its military might in annexing Sikkim in the 70s. That said, it is better that India have them both to offset China, and to prevent a Jihadi takeover of India by Pakistan.

    Bottom line: the US ain't the problem. China and Russia are.

    I guess setting up puppet governments in places like Iran and Chile doesn't count, as far as you're concerned? Or failing to do so, such as in the Bay of Pigs fiasco?

    I always have to chuckle when I see comments like yours, made by Americans who are so blindingly ignorant of their own history.

    Iraq is currently a client state of Iran, never mind the process by which its current regime got there. Had Iraq been pro-US, there would have been no persecution of Iraqi Christians. Nor would Iraq have cozied up to Iran, who the US has been trying to isolate: they'd have happily joined the US and tried to become the major power in the Arab empire. Afghanistan too - Hamid Karzai started mending relations w/ the Taliban even when the US still had a presence there. Some puppets - these 2!!!

    Half the world? I imagine you're talking about the #countries, right? About 50 of them are members of the OIC, and therefore rather hostile to the US. East Asia - the only friends that the US has are Japan, Taiwan, Philippines, Thailand and Cambodia. Sub Saharan Africa - not a single country is pro-US. Latin America - Venezuela, Brazil, Nicaragua, Bolivia, all have leftist regimes - I think Colombia is the only pro-US country there, and maybe some central American countries, like Costa Rica.

    Hardly half the world, as you put it. And if you were thinking in terms of populations, India and China are both allied to Russia, and have been supporting them both re: sanctions. That's half the world's population right there, b/w these 3 countries. And if you were thinking area wise, then too these 3 take the bulk of it, plus countries like Brazil and much of North Africa.
