    Well US can use those gliders from European bases also. Afterall NATO purpose is that only.Looking at the developments China is seriously working on its HGV. They already tested it 6-8 times having speed Mach 10 meanwhile US Darpa Glider having speed Mach 20 failed in the test and US stopped its testing after that saying they got enough data from the tests. Now moving to Russia they were also looking at Mach 10 Gliders projekt 4202 but they always failed in their tests, don't know the reason. US has already upgraded its tactical B61-12 nukes with precision guiding.

    Ziron springs to mind, but I suspect there are a range of long and very long range AAMs they will want to test from air platforms.

    Just having a 150kg hardened steel plug in the core of a mach 4-5 missile would mean an actual warhead would become unnecessary for targets like large ships or even heavy building structures.

    Correct me if I am wrong but Zircon is not 12Ma class but 7Ma class missile.

    Zircon speed: V = ~2,380 m/s
    Warhead energy eq for 1kg: Eq=0.5x(1kg) x V2 = 5,66x10 pow 6 Joules
    TNT equivalent of 1kg TNTeq= 4.184×106 J


    Energy delivery ratio for kinetic/chemical warhead is 1,35.

    With Ma=5 missile is 0,7 Thus explosive still can deliver 150% more energy to the point. More speed needed.

    The ministry of defense is planning launch of one RS-18 (UR-100NUTTH or SS-19). The liability insurance that would cover damages to third parties should anything go wrong for RS-18/UR-100NUTTH/SS-19 the coverage is much higher - 1.2 billion rubles (about $15.6 million). Which is probably not surprising - about the only reason to launch a UR-100NUTTH missile is to test the Project 4202 vehicle. Unlike all other launches, this kind of a test can do more damage on the ground if anything goes wrong. In any event, it is highly probable that Russia is planning one Project 4202 test in 2016-2017.

    Lockheed’s Marillyn Hewson Touts Breakthroughs in Hypersonic Weapons





    Lockheed Martin’s unmanned SR-72 aircraft concept has surfaced again with renewed vigour, with company leadership now pushing a reusable, air-breathing hypersonic vehicle as an “affordable” way to validate a new propulsion concept for achieving speeds within the atmosphere between Mach 6.0 to Mach 20.

    Speaking at a Lockheed media event in Washington DC on 15 March, company chief executive Marillyn Hewson confirmed that the company is building on “several breakthroughs” made during the short-lived HTV-3X Blackswift hypersonic testbed, which was de-funded by Congress in fiscal year 2009, to develop “a controllable, low-drag aerodynamic configuration capable of stable operation from takeoff to subsonic, transonic, supersonic and hypersonic to Mach 6”.

    Hewson, while displaying an artist’s rendering of the SR-72, said it would cost “less than $1 billion” to develop and fly a demonstrator aircraft the size of an F-22 Raptor.

    Devised by Lockheed’s Skunk Works division, SR-72 employs a turbine-based combined cycle propulsion system to get above "Mach 1.5 to 2.0," at which point it would begin converting to a supersonic combustion ramjet for speeds beyond Mach 6.

    That’s according to Skunk Works head Rob Weiss, who confirmed that it would be an unmanned vehicle, at least at first. Hewson says the company’s long-term ambition is to “enable hypersonic passenger flights and easier access to space”.

    The company’s militarised spinoffs could be an air-breathing, hypersonic reconnaissance aircraft, or perhaps even new fighters and bombers further along.

    Weiss says there is government interest but no programme of record currently, although DARPA might want to pick up where Blackswift ended and launch a proof-of-concept demonstration.

    Lockheed revealed its next-generation version of the famed SR-71 Blackbird, the SR-72, in 2013 and has said it would hope to introduce a reusable hypersonic aircraft in the mid-2020s or so. The challenge is transitioning through Mach 3.0 – since modern turbojet engines are only capable of powering an aircraft to Mach 2.2, whereas typical ramjets don’t work below Mach 4.0.

    Hewson and Weiss pointed to Lockheed's investments in hypersonic propulsion technology and high-temperature materials but didn’t say exactly how their concept will transition to from zero all the way up to hypersonic speeds except through combined propulsion technologies.

    In addition, the company is pushing super-fast, rocket-boosted weapons. Weiss says Lockheed will submit proposals for DARPA’s Tactical Boost Glide (TBC) and Hypersonic Air-breathing Weapon Concept (HAWC) demonstration programmes “later this month or in early April”.


    TBG, a high-speed glide weapon launched from a common vertical launch silo, follows in the Mach 20 contrails of the Falcon HTV-2 experiments that failed in 2010 and 2011.

    HAWC, meanwhile, builds on HyFly and the Boeing X-51A scramjet demonstration that ended successfully in 2013 after four flights.

    Funding for TBG jumps from $11.2 million to $22.8 million in DARPA’s spending blueprint for fiscal year 2017, and HAWC funding rises from $13.5 million to $49.5 million over the same period.

    “Twenty-sixteen will be a decision on winners; more than one, likely, on one or both programmes,” says Weiss, adding that flight tests are planned for 2018.

    Great input as always Morpheus. Many Thanks.

    This is just going to open up into a long line of questions. .I don't want to bother you. Last one, though. I am venturing to guess you won't have the time to explain each of these technologies in details, so can you please share some links, from where I can read about these technologies? Thanks again.

    Thanks, jhelb,

    I'll continue this topic in some future posts.

    Here is a link; hopefully more would be posted later.

    Even designation Yu-71 is not Russian but foreign. And we dont know anything about the project itself except that it exists and that tests were performed. Nothing about tests was ever released to public from what i am aware.

    That isnt proof, quoting yourself. As militorov said, it's all assumptions and guessing.

    It reminds me of the debate on anti sat weapons and ho Americans mocked Russians because China and USA had anti sat weapons and claimed Russians didn't. Then all of a sudden, Russia tested one not long after.

    I guess we'll have to wait for a successful flight test to see an official report on Project 4202 and learn more about the system.
    Thats from last li regard last test. So nothing has been official. So on again, speculations. Since it is from your source you linked us, it will satisfy you on why we are concerned, and why we do not take it at face value.

    So Russia could make the Buran which landed from orbit on autopilot, but can't make a toy version of this? Get f*cking real.
    Nothing in the NATzO associated press, which includes most of the 3rd world media, pertaining to Russian technology and
    science capacity can be taken seriously. It is all transparent, chauvinist, racist BS of pure wishful thinking and projection.
    There is no actual reporting of facts, just an endless stream of delusional masturbation.

    The Problem with the Pentagon's Hypersonic Missile




    Military officials say their superfast weapons of the future won’t carry nuclear warheads. But will other nuclear nations believe it when the missiles start flying? pirat


    The U.S. military is pouring money into hypersonic research, and it’s making China and Russia —which have their own similar programs — nervous. But the accelerating effort to build missiles that fly at speeds between Mach 5 to Mach 19 is also alarming some in the nonproliferation community. Despite Pentagon officials’ assurances that superfast weapons will carry only conventional warheads, some believe that other nations may well treat any hypersonic launch as a potential nuclear strike.

    It’s been a good year for hypersonic researchers, who got a 50 percent bump in the Defense Department’s 2017 budget request. The Air Force plans to test a hypersonic missile by the end of the decade.

    The Pentagon, whose long record of hypersonic research stretches from the X-15 rocket plane to Boeing X-51 scramjet and beyond, is today funding the Lockheed Martin Falcon Hypersonic Technology Vehicle 2 program, the Raytheon Hypersonic Air-breathing Weapon Concept (HAWC), and the Raytheon/Lockheed Tactical Boost Glide. The Defense Advanced Projects Research Agency gave Raytheon $20 million and Lockheed $24 million for the latter.

    Raytheon is pouring tens of millions of its own dollars into hypersonic research.

    “These are very specific point design weapon systems. We have picked design points where the technology is available today and we can put these things together as systems now,” said Thomas Bussing, vice president of Raytheon’s Advanced Missile Systems. He added that 3D printing and additive manufacturing have reduced the complexity of hypersonic devices. “Not only can you build them, you can build them affordably.”

    The company is working on two kinds of hypersonic missiles. One is a boost glide system that rides a rocket into space, then reenters the atmosphere and glides to its target at up to 14,000 miles per hour. The other is an airbreathing missile, a close cousin to the ramjet, that scoops up oxygen as it flies a flatter, Mach-10 path to its destination.

    The primary challenges in the boost glide system were “materials, stability control, the aerodynamics of the vehicle itself,” according to Bussing. In the air-breathing missile, “it’s all about the engine and having the engine operate over a range of conditions.”

    Unlike the ballistic path followed by an ICBM plummeting toward its target, a cruise missile can steer its way past defenses, or, in some cases, sneak in below radar coverage. Being able to strike so quickly has distinct advantages, if you’re trying to penetrate sophisticated air defenses.

    Interest abounds; the Navy is considering arming its ships with a tactical boost glide weapon, said Joe Doychak, the associate director of aerospace technology for the assistant defense secretary for research and engineering.

    What do you do with a rocket that can travel that fast over intercontinental distances? A 2014 RAND report noted hypersonic technologies “could be used in future nuclear-armed systems.” The Pentagon could—if it chose to—turn hypersonics into an entirely new type of nuclear weapon.  

    “At this point, our hypersonics program is really a technology development program, purely focused on conventional” payloads, said Stephen Welby, assistant defense secretary for research and engineering. “There’s nothing in the budget” related to modeling, researching, or exploring nuclear-armed hypersonics.

    While the U.S. is also planning to spend more on modernizing U.S. ICBMs, the “two things are uncoupled” Welby said Wednesday at a National Defense Industrial Association, or NDIA, event here.  

    Asked about potential payloads, a Raytheon spokesman said only that “the hypersonics programs on which Raytheon is currently a performer are focused on advancing the technologies that support hypersonic flight. The eventual application of those technologies in support of a customer mission is for the customer [the U.S. government] to answer.”


    Superfast Strike Jet

    The ultimate goal of today’s hypersonic research, military leaders say, isn’t a nuclear missile but a re-usable hypersonic jet.

    “We see this as being a long-range program,” David Walker, the U.S. Air Force deputy assistant secretary for science, technology and engineering said at the NDIA event. “It’s 2020 for the missile, 2030 … until you get into something that’s refurbishable” [meaning an aircraft you could potentially use again] and probably 2040 until you get into something that’s a totally reusable type of capability.”

    In his presentation, Walker laid out the Air Force hypersonics roadmap. It starts with a quick-firing tactical strike missile, ready around 2020. Around 2030, it foresees an ISR craft capable of “deep strike of high value targets.” And finally, a “re-usable and persistent” ISR and strike craft labeled “tech ready by 2040.”

    The military sees hypersonic airplanes as one answer to the rise of more capable programmable radar. “Our ability to operate in a stealthy mode is starting to lose its advantage because of the advanced radars,” Dick Urban of the Defense Advanced Research Projects Agency, or DARPA, told the crowd at NDIA. “We think that speed is going to give us that extra advantage.” (Welby called advanced programmable radars “a challenge” but said that they did not necessarily make stealth obsolete.)

    But that doesn’t mean that hypersonics are invisible. They’ll have a bright infrared signature visible from space.

    Inherently Destabilizing?

    The same speed advantage has alarmed members of the non-proliferation community, who believe hypersonics raise the risk of nuclear conflict.

    “I see hypersonics as weapons whose only plausibly logical use would be a niche role in a strategic first strike vs. Russia or China. So the nuclear standoff already exists, and this road is taking us closer to war,” physicist Mark Gubrud said by  email. (He also says the speed advantage of hypersonics is overstated; ICBMs are still faster.)

    An enemy would have no way to know whether or not such a missile was carrying a conventional or nuclear warhead.

    “If I see a cruise missile flying over, I have to assume it’s nuclear,” William Perry, a former defense secretary, said at a recent event in Washington.

    He is not unique in that concern. Tong Zhao, an associate in the Carnegie Endowment’s Nuclear Policy Program, echoed this concern in a June essay for the Bulletin for Atomic Scientists. “Some analysts in China suspect that the United States is seeking the ability to eliminate Beijing’s nuclear deterrent in a first strike—and if Washington successfully develops hypersonic missiles, Beijing’s confidence in the credibility of its nuclear deterrent would only erode,” Zhao wrote. “Already, some in China are discussing whether Beijing should, in the face of new conventional threats to its nuclear arsenal, alter its unconditional no-first-use policy.”

    China is also working to develop hypersonic cruise missiles and has already conducted six tests of a hypersonic weapon, the WU-14. Russia and India are also planning to test a hypersonic missile called the BrahMos capable of reaching Mach 7, in 2017.

    In the same series of essays for the Bulletin, Gubrud called for banning even tests of hypersonic weapons, arguing that such a prohibition “stands out as an easy and highly significant opportunity to resist an onslaught of destabilizing weapons technology.”

    The history of U.S. advances in hypersonics is intertwined with nuclear weapons research, Gubrud points out. “The US has tested maneuvering reentry vehicles which were intended for nuclear delivery. The Advanced Hypersonic Weapon, successfully tested in 2011, was derived from the Sandia SWERVE [Sandia Winged Energetic Reentry Vehicle Experiment] maneuvering reentry vehicle, which was intended as a nuclear warhead,” he told Defense One.  Question

    “The US may not be planning to use hypersonics for nuclear delivery, but US statements allege that Russia and China do intend to do so, and the technical possibility is clear,” he says. “More importantly, even non-nuclear hypersonic weapons would be mainly intended to attack strategic targets including nuclear weapons and the infrastructure of nuclear war.

    The best way to prevent this needless uptick in the nuclear arms race would be to initiate a moratorium on hypersonic missile testing (both glide vehicles and cruise missiles) and challenge Russia and China to reciprocate and to negotiate a permanent ban.”   pwnd

    The unique advantages that the Pentagon sees in hypersonic technologies suggest that is unlikely to happen. tongue

    USAF using X-51 lessons learned to weaponise hypersonic vehicles



    The X-51A Waverider carried under the wing of a B-52. The programme has become the basis for several follow-on weapons aimed at producing a hypersonic capability for combat aircraft

    A 2013 demonstration of the Boeing X-51A Waverider is the basis for the US Air Force's plans to weaponise hypersonic vehicles, an Air Force Research Laboratory (AFRL) official told IHS Jane's

    "We're taking lessons learned from X-51 and using them in development of HSSW [high-speed strike weapon]," said John Leugers, the principal aerospace engineer at the AFRL munitions directorate.

    HSSW is a Lockheed Martin Skunk Works concept under which the company plans to demonstrate hypersonic flight and to provide the basis for future hypersonic programmes, including both expendable missiles and reusable aircraft.

    On 1 May 2013, the X-51 performed a successful flight on its fourth test. The vehicle detached from a B-52H and was powered to Mach 4.8 by the booster rocket. It separated from the booster and ignited its own engine. The X-51 then accelerated to Mach 5.1 and flew for 210 seconds until running out of fuel. The USAF collected telemetry data for 370 seconds of flight.

    Leugers said the emphasis on hypersonic technology is based on a threat assessment and highlighted a particular need for long-range systems.

    He added that ordnance and a guidance system are under development via two demonstration programmes: the high-speed air-breathing weapon concept (HAWC) and the tactical boost glide (TBG). Leugers said the warhead under development for a hypersonic missile is in the 250 lb class, about the size of a small diameter bomb (SDB).

    The Pentagon's Defense Advanced Research Projects Agency (DARPA) in April awarded Raytheon USD20 million to continue development of the TBG programme. The goal is to accelerate a weapon to Mach 5 or greater and allow it to glide to its target. Such weapons would have to be highly heat-resistant and manoeuvrable. TBG could ultimately fly at altitudes of nearly 200,000 ft.

    Could the US's new hypersonic missile spark World War 3? scratch

    The US has reportedly created a new missile as part of the Pentagon's development of hypersonic technology. But the US military has insisted that the weapons will carry conventional missiles rather than nuclear ones, as the arms race with China and Russia grows more intense.

    The new missiles – according to information released on 13 April – will reportedly fly at five times the speed of sound (3,800mph) and make them virtually impossible to detect using radar. Researchers are still working on manoeuvre techniques and developing ways of being able to fully control the weapons.

    The Pentagon's Defense Advanced Projects Research Agency (Darpa) has spent over $34m (£48m) on hypersonic aircraft and weapon projects. Hypersonic aircraft would be able to fly at between five to 10 times the speed of sound.

    New nuclear fears

    In an article titled The Problem With The Pentagon's Hypersonic Missile, published by Defense One, three hypersonic projects – including the Lockheed Martin Falcon Hypersonic Technology Vehicle 2 program, the Raytheon Hypersonic Air-breathing Weapon Concept (HAWC), and the Raytheon/Lockheed Tactical Boost Glide – are being examined over whether they would remain conventional weapons, or whether they would spurn the other military superpowers, China and Russia, into developing more nuclear weapons.

    The concerns are that hypersonic missiles will allow the US to launch nuclear weapons that could strike targets at longer ranges, in less time than conventional ballistic missiles require, and move so fast current missile defence systems and fighter jets could not intercept them.

    Reports suggest that the new generation of missiles can switch between two modes: scramjet –which uses air flowing at supersonic speeds through its engine to further accelerate the missile – and a "boost glide" system – this would extend the range of missiles by making them 'skip' across the Earth's upper atmosphere.

    "Hypersonic weapons can be more survivable because of the extreme speed and high altitude. They would be hard to stop,' said JR Smith, director of Raytheon's Advanced Land Warfare Systems.

    "At this point, our hypersonics program is really a technology development program, purely focused on 'conventional' payloads, said Stephen Welby, assistant defense secretary for research and engineering at The Pentagon. "There's nothing in the budget related to modelling, researching, or exploring nuclear-armed hypersonics.

    "It's 2020 for the missile, 2030…. until you get into something that's refurbishable and probably 2040 until you get into something that's a totally reusable type of capability."

    Last year, four flight tests of the X-51 WaveRider – the US's prototype hypersonic aircraft – had taken place in June. During the last test the aircraft flew more than 230 nautical miles at Mach 5. It was launched from under the wing of a B-52 bomber and travelled at a height of 70,000 ft.

    If you didn't know better you would think these hypersonic weapons were unstoppable super weapons that no one would be safe from... the thing is that most ICBMs and SLBMs are actually much faster... Mach 26 or thereabouts...
