back to article DARPA says US hypersonic missile is ready for real world

DARPA announced a second successful test of its hypersonic cruise missile, adding that the weapon, capable of speeds in excess of Mach 5, is ready for real-world use.  DARPA has been testing hypersonic weapons for several years. The program in question, called the Hypersonic Air-breathing Weapon Concept (HAWC), began in 2016 …

    They've tested two completely different designs for one flight each, and consider that this comprises a battle-ready system...?

    I'm no military expert, but this sounds just a trifle optimistic to me.

      The Americans have been testing hypersonic missiles at the Woomera RAAF test range in Australia since at least 2015 many of which have been openly reported, my guess is that the two mentioned are essentially "final design" concepts or demonstrators from two different manufacturers using the data gained by numerous previous tests.

      Re: Sooo...

      An under-lighted aspect of the hypersonic missile development is the chemistry of the propellent.

      and maybe its on that aspect the Russians made the technology gap between us. The " speed " of the flame /reaction of that specific (synthetic ?) fuel mixture is key (even if you slow down the air in the chamber ) and that is really top notch chemistry. (maybe a topic the author can enlighten us more in a next article )

        ... and quite a stupid one: a hypersonic missile is basically a small Space Shuttle on top of an ICBM. It's supposed to go up in space, fly ballistic – even once around Earth – and hit it's target while in controlled "glide" down the atmosphere, doing escape maneuvers to avoid interception. Since it's going up into space, the maximum speed can far exceed that of an air-breathing cruise missile. It's both more lethal and more difficult to intercept and easier to do.

      eh, keep in mind that the Soviet Union (and now Russia) are big on claiming that they can do certain things but do so ONLY to invoke fear. On the other hand, the USA and its allies typically release information on the UN-classified capabilities of a weapon, ship, aircraft, yotta yotta yotta.

      Now... HOW long was it before the stealth fighter and stealth bomber were confirmed? They flew for years around places like Area 51 and were claimed to be UFOs but aside from possible REAL tech that is like a space alien aircraft might be, I would assume that most UFO sightings near test ranges are probably "OURS".

        You have to wonder about cooling for a device that's supposed to be both sea-skimming and capable of mach 10. The SR71 Blackbird was capable of acheiving speeds that would start to melt it (even at high altitude) - and that was about mach 4 and a bit. OK, bigger surface area, but also flying at 80,000 feet.

        So I wonder if those claimed ridiculous speeds are when flown in a ballistic flight-path - when anybody can be hypersonic? For example the Kinzhal missile that Russia lobbed at Western Ukraine last week was breathlessly claimed to be hypersonic. But it's just an air-launched version of their normal Iskander tactical ballistic missile. And not exactly super-accurate either. So good enough for attacking large fixed ground targets, but not much use at killing aircraft carriers - which have the distressing tendency to move about.

        This is why Russia has failed to neutralise Ukraine's air defences. Yes they've got massive firepower. But airbases are large, and their missiles aren't quite precise enough to guarantee hitting the important things like planes on the ground or the actual runway. Which means you'd have to fire lots at the airfield. They also aren't accurate enough to hit individual SAM launchers and radars They've got shorter-ranged air launched stuff but that has to be fired from within missile range which they either can't do - or don't want to take the required aircraft losses to do so.

          Add to that: they have a limited supply of aircraft and missiles and unfortunately for Russia they can't currently build more/repair what they've got because the components and spares were all made in Ukraine. Ooops.

      News just in: arms manufacturers like to use wars to sell their wares. Unfortunately for the Russian military machine the Ukrainian show of Mother Russia's almighty weapon wondery* is going that well.

      • the tanks are being taken out by minute men
      • the guided missiles are rarely guided (some of them are going boom before they leave the depot). In fact the best ones seem to be in their navy and there don't seem to be many of those left.
      • the hypersonic ones used were from the display cabinet
      • the aircraft can be taken out by some pretty aged systems
      • they can't manufacture any spares
      • the missile launchers may come with the wrong tyres and are likely to get stuck in mud

      Elsewhere, orders are flooding in for Stingers™, Javelins™, etc. Switchblades™ will presumably be on the list once the Ukrainians are able to deply them (Kherson looks likely) along with their own homegrown loiterers-with-intent. And Turkey can probably sell 10 times more of its drones than it can make; and it will have to get the US permission for components to make more.

      In other words: after years of disappointment with wars against people armed with little more than machine guns, the US arms industry has been able to show what even limited numbers of its systems can do against a supposedly well-equipped adversary. This is probably one of the reasons why Russia has gone all "Chechyna" on the civilans using murder, rape and hunger where weapons have failed.

        According to yesterday's reports , the Ukrainians now have 10 anti-tank missiles for every russian armored vehicle on the battlefield.

          what might happen is that the initial onslaught is already finished (after 2 months) and now the Russians are digging in and keeping/defending what they have grabbed in the east. In which case anti-tank manpads are useless.

          I have the feeling that the NATO is always 1 step late.

        2. Charlie Clark Silver badge

          The rules change as soon as you go from defensive to offensive strategies, which is why to retake Donbas (and the Crimea) Ukraine is going to need different weapons. To succeed defensively, you just need to survive longer than the other guy. The civilian population will provide support and shelter as long as possible.

          Going on attack and your supply lines quickly become your biggest problem. If you move into enemy territory you also have to know how you're going to deal with the civilian population. Will it cooperate? Or will it need "subdueing"? And feeding?

          There is no appetite in Ukraine for anything other than reclaiming post-Soviet territory and there won't be weapons for anything else. That said, there are no doubt plans and discussions in the Pentagon, Langley and elsewhere for actions in Belarussia, Georgia, Transnistria, et al. And I've no doubt that there are assessments of whether parts of Russian military will turn against the Kremlin if the war continues to go this badly.

          But in the meantime the Russians will continue to shell cities indiscriminately and use what precision missiles they still have as well as possible but also the terrorise the civilian population in occupied terrritory through murder, rape, hunger and torture.

                Ballistic armour? Having seen what a stream of molten copper does at these sorts of speed I'm not sure things are actually solid at these sort of impact speeds. I have a feeling a spray of buck shot in front of them would at least upset the steering and possibly cause enough damage to the air intake to prevent the engine working. But then the simple speed of these things and their steerability makes it pretty hard to get in front of them let alone accurately enough to be of much impedance.

        You assume much here. The US military has had the ability to wipe the floor with the Taliban, just as they did in Viet Nam and Korea. The problem never has been the military, it's always been the political machine giving the orders. The political machine fights wars via public opinion, not war realities. Example - in 1991 (the war I was in) the US military took 3-4 days from "GO" to the gates of Baghdad, but was stopped by President Bush the Elder because he didn't want to upset other Middle Eastern nations that were shocked and dismayed at how quickly Hussein went fron being a top regional military power to hiding in a hole. Iran and Iraq fought each other to a standstill for 7 years, we smoked one of them in 72 hours. If US politicians were not allowed to control the military once a war is declared, then the US military would have won every war it was involved in since WW2. America has always had the military might, but political will sways with the breeze and is a staunch as a saltine before a sandblaster.

    Optional warhead

    The article states that just the kinetic energy of a lump of metal travelling at greater than Mach5 is equivalent to several tonnes of TNT. I recall that during the Falklands conflict one of the UK's ships was destroyed by an Exocet missile whose warhead failed to detonate, it was the heat of the engine and the unspent fuel that set the ship ablaze.

    Technically in order to be a munition, a flying, guided object needs to have a warhead, otherwise it is 'just' a controlled craft, and not subject to arms controls.* one of my former colleagues had a radio-controlled model aircraft, jet propelled, which was so fast he needed a proper runway to fly from as it would quickly escape radio contact when in flight if he couldn't see it.

    *This may no longer be the case, please advise if you know better. Obviously ballistic objects like bullets are legally munitions.

    Two things.

    First, The US had hypersonic missiles in the 1950s. They were Nikes, capable of hitting Mach 4+, and Sprints which hit Mach 10. "Hey, George. Let's reinvent the wheel again and abscond with a few billion mopre from Uncle Sam."

    Second, isn't HAWC what you do when you got crud stuck in your throat?

    1. John Brown (no body) Silver badge

      Were they controllable once launched, either by remote control or onboard systems?

      1. Spherical Cow Silver badge

        Yes, Sprint was controlled by ground-based radio guidance, which needed a very powerful signal strength to get through the superheated plasma surrounding the missile (because it was travelling so fast at relatively low altitude).

      2. sreynolds

        Nikes were guiided to a target so I guess they were controllable. I think t hat the beeb had a good pic on the glide path that could be taken by "hypersonic" missiles. The point is that in the launch phase once ballistic missiles are over the horizon they can be detected and targeted in the space segment and in the long re-entry phase. So when they mean hypersonic they mean something that takes a path closer to the earth like a subsonic cruiise missile only that it stays in the atmosphere below 100km

    2. Sin2x

      These were anti-ballistic missiles, not offensive ones.

      1. James O'Shea

        They were fitted with either half a ton of explosives or a 2 or a 20 kt nuke. There was a Nike station in the Florida Everglades, officially to cover Miami and Ft. Lauderdale. The effective slant range of a Nike Hercules mean that Havana was in range. I'm sure that a 20 kt warhead going off above Havana would have got Fidel's attention.

        And, while on the subject of nukes... There are some who claim that Boy George Bush skipped out on his time in the Air National Guard. His unit, the 111th Fighter Interceptor Squadron, Texas Air National Guard, flew F-102 fighters and had responsibility for the air defence of the south east US. Including Florida. (He later moved to an Alabama squadron, also flying F-102s, also tasked with the air defence of the south eastern US.) Typically, F-102s in air-defence configuration carried five Falcon missiles, usually three infra red guided and two radar guided, and one Genie rocket with a 1.5 kt warhead, or six Falcons, three of each. The idea was to use the Genie to break up Soviet bomber formations, and then go hunting survivors with Falcons and then go home, F-102s didn't have a gun. F-102s could get within Genie range of Havana from Alabama; they'd probably need refueling to get there from Texas. I wonder what a few 1.5 kt Genies would do to Havana... Boy George (sometimes) had a nuke directly under his control. Shouldn't those who think that he's stupid, which in comparison to a certain recent ex-Prez he isn't, be happy that he skipped out on the job?

        (Every day that certain recent ex-Prez makes Boy George look better and better.)

      Re: Next breakthrough

      The British Starstreak SAM already hits nearly Mach 4. And that's a shoulder-launched (or tripod launched) man portable surface to air missile. Stick a slightly bigger booster rocket on it and maybe you could go even fast, just not be able to carry it. As it happens that's actually 3 little foot long tungsten steerable darts rather than one missile.

      But actually quite a lot of SAMs already go more than mach 5. As do lots of ballistic missiles when coming down. I think what makes you properly hypersonic is the ability to maintain that mach 5+ speed, rather than just having a booster and then coasting/falling.

      1. mcswell

        Re: Next breakthrough

        What makes a weapon hypersonic is the speed AND the ability to steer. Although I'm not sure how the old MIRVs fit into that--they were independently targetable, but maybe the targeting needed to be done while they were still outside the atmosphere.

    4. I ain't Spartacus Gold badge

      Re: What the heck was Pershing II then?

      Chairman of the bored,

      Most ballistic missiles are hypersonic. I think quite a few of the larger surface to air missiles also get above mach 5. But in both cases they have a large booster to get them up to speed, and then coast. In the case of ballistic missiles the really fast bit is done on the way back down.

      Lots of the press don't get this, so don't clearly understand either.

      But a proper hypersonic missile is able to achieve its mach 5 in level flight and then sustain it with its engines, rather than just coasting after being boosted to high speed. Plus they're supposed to be steerable, though I do wonder about that.

      I'm a bit more sceptical of the claims of stuff doing hypersonic speeds at sea-level without melting. The US tests I've read about have been achieving top speed in the upper atmosphere, so you then wonder how much different they are to ballistic missiles in their final attack phase?

      How much is hype and how much is really hypersonic?

      For example if they've got a plasma shockwave in front of them that's impervious to radar (supposed "plasma-stealth") - surely that in itself is detectable? There's an area of superheated plasma moving towards us at mach 10 sir, shall I ignore it?...

Does Russia do that? Unless the charge works pretty much perfectly the yield can easily be reduced by anything up to 20 orders of magnitude.

      > the yield can easily be reduced by anything up to 20 orders of magnitude.

      100Kt of TNT is 10^14Joules

      20 orders of magnitude less than this is 10-6Joules

      1 microjoule is about enough energy to lift a mosquito one mm

      1. Grunchy Silver badge

        Right, the nuclear detonation tries to last about 1 millisecond, during which 1 neutron hits another nucleus, shaking loose another 3 neutrons that hit 3 other nuclei. The goal is for the nuclear mass to hold together long enough for that to repeat about 20 times or so. So a ‘perfect’ detonation might release 3^20 neutrons (from the initial decay), an imperfect detonation would be somewhat less. How much less? Depends what didn’t “work right.”

        You’re right, 1^20 neutrons going off all at once may not register very much…
