US Hypersonic Missile Fails In Test In Fresh Setback For Program (bloomberg.com) 65

A flight test of a hypersonic missile system in Hawaii ended in failure due to a problem that took place after ignition, the Department of Defense said, delivering a fresh blow to a program that has suffered stumbles. Bloomberg reports: It didn't provide further details of what took place in the Wednesday test, but said in a statement sent by email "the Department remains confident that it is on track to field offensive and defensive hypersonic capabilities on target dates beginning in the early 2020s." [...] The trial marked the second unsuccessful test flight of the prototype weapon known as Conventional Prompt Strike. There was a booster failure in its first flight test in October, which prevented the missile from leaving the launch pad. The Conventional Prompt Strike weapon is envisioned to be installed on Zumwalt destroyers and Virginia-class submarines. "An anomaly occurred following ignition of the test asset," Pentagon spokesman Navy Lieutenant Commander Tim Gorman said in the statement. "Program officials have initiated a review to determine the cause to inform future tests." he said. "While the Department was unable to collect data on the entirety of the planned flight profile, the information gathered from this event will provide vital insights."

      Actually they'll probably have a very good clue why very soon.

    • We don't need to know why any more than we need hyperdoopersonic missiles in general. What Russia has more than adequately demonstrated that we need a fuckton of is (a) Javelins and (b) some replacement for the Stinger. Scrap the hyperdooper toys and use the money to churn those two out at the maximum possible rate.

            All ballistic missile reentry vehicles are "hypersonic", and impractical to defend large targets like a major city from. You can't defend Chicago from a Russian R-36 "Satan" missile either, because the reentry vehicles are, and always have been, hypersonic. The "hypersonic missiles" used by Russian in Ukraine are actually just air launched medium range ballistic missiles. Calling it a "hypersonic weapon" is largely PR posturing to bolster Russia's image as a technologically advanced military power. However if the KH-25 is a "hypersonic missile", so is a Pershing 1 missile from the 1960s.

            More sophisticated "hypersonic" systems are either ballistic missiles with steerable reentry vehicles or are scramjet-powered cruise missiles. The world is in a classic arms race situation with these things; military powers are rushing to create them but their practical significance is uncertain, particularly in light of their cost. A functioning hypersonic cruise missile is *estimated* to cost in the 100 million dollars/unit range. And that's a *military procurement cost estimation*; so realistically you have to double that..

            These missiles could be highly effective at attacking compact targets like ships or ammunition dumps, but if they are, will they actually be cost effective? Would one hypersonic missile really be more effective than salvo of 200 tomahawk cruise missiles, or 28 Minutemen ICBMs? Probably not. But it's not rational calculation that's driving the development of these things, it's arms race emotion in which everyone is imagining themselves helpless in the face of the enemy's Wunderwaffen. So pretty soon everyone's going to have these things, and then either we'll figure out a use for them or we'll end up with some kind of arms limitation treaty that enables countries to stop wasting billions of dollars.

            • their practical significance is uncertain, particularly in light of their cost.

              That is their practical significance. We will pay defense contractors billions to trillions to design and produce these weapon systems that we arguably do not need.

              You are correct that ballistic missiles have the same, or usually better, military characteristics than these hypersonic systems - but they are not the same. The hypersonic systems do fly in the atmosphere and have air-breathing engines.

              The key feature of the 3M22 Zircon for example claimed as advantages is "plasma stealth", the fact that the super-heated plasma envelope in front of the missile reduces its radar signature by absorbing radar energy. But it is not clear that this works better than regular stealth using shapes and materials. The plasma stealth for example is not going to work as well from the side and rear, where tracking radars may be located.

              The trajectory of the Zircon is going to be lower than a true ballistic missile, so a shorter radar horizon, but still quite long since the hypersonic flight is at high altitude. But this thing is an intense IR emitter and will be easily acquired and tracked by IR sensors. So how this is a win for "stealth" is unclear.

              The U.S. developed a strikingly similar weapon - way back in the late 1950s. It was called the Navajo and was an air breathing cruise missile, that flew at hypersonic speeds, at extremely high altitude and was very hard to intercept, could fly very long distance, and was stealthy. It used "regular" stealth, and did not fly as fast -- Mach 3.1, still hypersonic (barely).

              But is was not deployed because ballistic missiles with similar capabilities, but were faster and even harder to intercept, came along at the same time.

              • by Rei ( 128717 )

                The other aspect is that an atmosphere-maneuvering hypersonic vehicle is a harder target for intercept than a ballistic missile with only limited atmospheric maneuvering time and limited maneuvering capacity.

                Re ICBMs, IMHO, the more I've thought about it, the more I keep thinking that low-altitude microsatellite constellations are the solution. Namely: nuclear warheads have difficulty scaling down beyond a certain point. But microsatellites can get vastly smaller. So launch polar orbit rings of tens or eve

                  I'm not sure filling up LEO with large numbers of military satellites is a good idea. They might be seen as weapons and lead to the militarization of space too.

              • Navaho was a fast supersonic cruise missile. With a cruising speed of mach 3.1, it’s about two mach below hypersonic.

                The Skybolt air-launched ballistic missile, developed in the 50s and cancelled before deployment, is a better comparison — flying the same mission profile as the Russian Kinzhal, more or less. Good job Russia, you’re only 70 years late to this technology!

                Interestingly, the Navaho was originally intended as a boost-glide missile, along the lines of Chinese hypersonics and th

              • I'm extremely skeptical that a hypersonic missile can be stealthy at all. The plasma will absorb some radar, but also scatter a lot. There isn't a lot of freedom to control the structure of that plasma to make it a broadband absorber. Also, as you point out, its also going to stick out like a sore thumb on infrared. I think the hypersonic relies on out-maneuvering the interceptor to run it out of energy, but how well that works in practice remains to be seen. The hypersonic has to be able to detect the

                Where did you read that? If that is what they are relying on for radar stealth, then it is not going to work at all. Plasma is an excellent radar reflector which is why meteor scatter works so well for communications.

            • by AmiMoJo ( 196126 )

              Hypersonic missiles are tactical weapons. More worrying are their new drone nuclear tipped torpedoes. Thousands of kilometres of range, very difficult to detect during the stealthy travel phase, and very hard to hit during the high speed attack phase. They can also run very deep.

              With ICBM defences improving I think Russia will probably switch most of its retaliatory submarine force to those things.

              • With ICBM defences improving I think Russia will probably switch most of its retaliatory submarine force to those things.

                I hope they do. Rationally, the Russians should worry more about developing useful, nuclear powered submarines that operate quietly. Those sooper-dooper torpedoes won't do much good if Russian subs can be detected thousands of kilometers away and preemptively sunk before they're in range for a useful torpedo launch.

                • Well, here comes the tricky part: if Russian subs can be detected thousands of kilometers away

                  If you figure a way to do that: you will either be very early very dead, or very rich.

              • There are a lot of possible ways to make extremely stealthy submarine drones. I suspect both sides have them. I remember looking at one possibility many years ago out of curiosity, and finding a university group had started working on it, then went silent.
            • So, it is PR, that Russia has hypersonic missiles, in the sense of the word, not in your stupid idea of "hypersonic reentry" - and China has them, too: but USA not?

              So, the cities in Ukraine get bombarded by hypersonic PR missiles - which do not exist? What fucking news channel are you on?

              • by hey! ( 33014 )

                Whether Ukraine is getting bombarded by "hypersonic missiles" depends on your definition of "hypersonic missile". I follow the same news channels as everyone else -- channels whose reporters have no idea what a "hypersonic missile" means and takes Russian MOD propaganda at face value.

                It is completely accurate to say Ukraine has been bombarded with KH-47 Kinzhals, air launched ballistic missiles which reach unguided hypersonic speeds during reentry. You *could* call that a "hypersonic missile", but in that

                • A hypersonic missile is a missile that goes 4 time, or above, the speed of sound.

                  Sorry, no idea about what you want to nitpick. We are talking about hypersonic missiles not about "ballistic missiles" that achieve hypersonic speeds.

                  Can't be so hard to grasp the difference.

                  Usually what is meant by a hypersonic missile is either (a) a ballistic missile reentry vehicle that can *maneuver* , no, that is not what hyperssonic means. That is a ballistic missile.

            • There was a claim that the Spartan / Sprint defense system had a pretty high kill rate against incoming ICBMs. Of course they used nukes on the interceptors - so " close" counts. Not saying we wouldn't get our hair mussed....
            • The difference between a subsonic and supersonic cruise missile is arguable, esp. in terms of survivability vs. payload mass. An air breathing scramjet hypersonic weapon is one with subsonic missile mass but achieving velocities that currently only solid-fuel rocket powered weapons (i.e. big, heavy, bulky and expensive) can manage. They're an absolute fucking gamechanger.

        • by splutty ( 43475 )

          Nothing "defends" against a hypersonic targeting anything. Just like there isn't any defence against nukes, so that's kind of a silly argument.

        Javelins and Stingers absolutely aren't winning the artillery battle in Donbas. One-size-fits-all solutions don't work in the real world.

        Stingers are only effective in Ukraine because Ukraine also has long-range air defense systems. This forces Russian aircraft to risk flying lower to avoid detection and engagement, as well as to maintain the element of surprise. Without the former, they could just fly high and carpet bomb with impunity, regardless of how many Stingers Ukrainian troops had.

      • Lol, stupids comment ever.

        Russia is bombarding Ukraine cities with hypersonic missiles. Everyone knows that, except you.

        They shoot them from planes that are 1000km away from their target, good luck shooting down a plane that is 1000km with a Stinger. A Javeline is an anti tank weapon. Has nothing to do with hypersonic missiles.

        A hypersonic missile flies at roughly 5000km/h that is ~4000mph -> there is no damn anti air missile in existence on the world that can intercept one.
