Of Russia’s New Hypersonic Wonder-Weapons the Avangard Boost-Glider Is the Least Immediately Useful
It is but insurance for the future 20-30 years from now in the unlikely scenario the US is able to field a ballistic missile shield that actually works
In March 2018, Vladimir Putin announced at his annual address to the federal assembly that a Russian hypersonic boost-glide system, named Avangard, would start entering serial production. Subsequently on December 26th, 2018 Russian officials claimed that they had successfully conducted a test from the Dombarovsky missile site, to the Kura test range on Kamchatka, some 3,760 miles away.
Russia’s president proudly announced that the system as a wonderful ‘New Year’s gift’ to Russia. According to Putin’s statement, the hypersonic glide vehicle is able to conduct intensive maneuvers at speeds in excess of Mach 20, which would render it “invulnerable” to any existing or prospective missile defenses.
In this article I will briefly explore the logic behind Russia’s hypersonic boost glide program, recent claims of technological accomplishment, and the strategic implications of deploying such weapon systems.
Despite rather questionable public statements about the technical characteristics of this weapon system, a number of which appear inconsistent, it is clear that Russian military science has made considerable advancements along one of the most sophisticated axis of weapons research.
While claims pertaining to the readiness of this system to enter serial production, and operational service, are probably exaggerated, the more important questions are conceptual. More than likely Russia will be able to deploy a hypersonic boost glide system in the 2020s, perhaps alongside other hypersonic weapons projects, but the promise of this technology was always at the tactical-operational level of war, not strategic.
This was never considered a ‘game changer’ as a system for the delivery of strategic nuclear weapons. If anything, Russia has invested a substantial amount of money, and years of research, in overdoing its strengths. Beyond a somewhat militant demonstration of ‘Russian national achievement’ for domestic audiences, it’s unclear if this weapon system truly answers Russia’s strategic challenges in the coming decades. The question is not whether it works, or when it will work, but does it even matter?
Hypersonic boost glide weapons function by using a multi-stage ballistic missile as the boost phase, throwing a vehicle into near earth orbit, which then descends and begins gliding at hypersonic speeds along the edge of the atmosphere. As the vehicle descends back to earth, it pulls upwards, and begins skimming the atmosphere in a ‘glide’ phase, before diving downwards onto its target at the terminal phase.
Russia has spent years developing this technology under a project referenced as Object 4202, which married a series of experimental hypersonic glide vehicles, such as the Yu-71, with a liquid fueled ICBM УР-100УНТТХ (NATO designation SS-19 mod 2 Stiletto). This system builds on the Soviet Union’s extensive research into hypersonic weapons programs , including work on a hypersonic-boost aircraft named «Спираль», a modified S-200V surface-to-air missile under the project name Холод, and hypersonic cruise missile programs, such as Kh-80 and Kh-90 GELA (гиперзвуковой экспериментальный летательный аппарат).
Although claimed successes in testing may have come as a surprise in 2018, in truth Russian officials have been announcing tests of a hypersonic boost glide vehicle, using the УР-100УНТТХ missile, as far back as the strategic nuclear forces exercise in 2004. Hence, this particular system has been in publicly acknowledged development for at least 14 years, and the glide vehicle itself for quite a few years beforehand.
The booster, УР-100 (SS-19), is a 105 ton liquid fueled silo-based missile, which together with the boost glide vehicle payload proved too long for a standard silo. Hence this system is being tested in a modified R-36M2 silo (SS-18 Satan), and although it is being developed with the УР-100, it is meant for the much heavier liquid fueled missile currently in testing, RS-28 Sarmat.
While the question of boost method may seem a technicality, the boosting mechanism is actually quite deterministic of the strategic role this weapon can play, as I will discuss a bit later in this article.
However, the principal challenges with this system have little to do with the decades established technology of intercontinental ballistic missiles, or boosting objects into near earth orbit. Hypersonic boost glide vehicles, if successful, represent a major breakthrough in material sciences, as the object must be able to withstand incredibly high temperatures with the payload and guidance system intact. Although impossible to verify, Russian announcements can often be categorized as ‘true lies,’ impressive sounding figures that have some factual basis, but are inevitably inaccurate.
The proposition that the vehicle can reach mach 27 is likely true only during the brief return phase, when it is falling back to earth like a rock from near earth orbit, prior to beginning its hypersonic glide at the edges of the atmosphere. The vehicle itself will have considerably different speeds during the pull-up, glide, and dive to target phase, while having to endure incredible temperatures.
Below are a few graphical illustrations available on the web
In U.S. testing of an analogous system in 2011, Hypersonic Technology Vehicle 2 (HTV-2), the vehicle was able to sustain glide at mach 20 speeds for three minutes, enduring a temperature of 3500 Fahrenheit. These figures track with Russian statements on temperatures experienced, but the actual speeds and altitudes at which the Russian vehicle is able to glide, and whether the systems actually survive this experience, remain a mystery. Although Russia’s defense sector seems to have made progress on this weapon system, claims that it is ready for serial production, or operational deployment in the near future, should be treated with educated skepticism. Ironically, the most significant potential breakthrough is in material sciences, not in building a seemingly scary strategic weapon.
Yet the rationale for Avangard seems less than straightforward when compared to other Russian hypersonic weapons programs, including the Tsirkon 3M22 scramjet hypersonic cruise missile, and the Kinzhal Kh-47M2 aeroballistic missile. Those are operational depth systems able to deliver meaningful conventional or nuclear payloads to shape the military balance in a theater of military operations. They can offset U.S. conventional superiority, and pose genuine challenges in conventional warfare.
What does Avangard do for Russia that existing silo-based, road-mobile, air-launched, and submarine launched missiles cannot?
The Avangard system is best seen as one element in an expensive Russian strategy to develop technological hedges for a security environment perhaps 20-30 years from now where the United States might deploy a cost-effective missile defense system, making a percentage of Russia’s nuclear deterrent vulnerable to interception.
To be clear, there is no missile defense system now, or on the horizon, able to intercept Russia’s strategic nuclear arsenal. Modern ICBMs can come with multiple reentry vehicles and numerous penetration aids or false targets, creating a complex ‘threat cloud’ that would make interception an improbable business.
Nonetheless, ever since the Bush administration chose in 2002 to exit the 1972 ABM Treaty, Russian leadership has been concerned that the United States could eventually devalue the deterrence provided by Russia’s strategic nuclear forces.
Russia’s General Staff worries that a vast arsenal of long range conventional cruise missiles, paired with a semi-viable missile defense, would pose major challenges for their calculations to ensure the ability of Russian nuclear forces to deliver ‘unacceptable’ or ‘tailored’ damage in the coming decades. The 1972 ABM Treaty was not just a cornerstone of Cold War arms control, but fundamental to Russian military thinking on strategic stability, based on mutual vulnerability at the strategic level. Ever since June 1941, Soviet, and subsequently Russian, military thought has been wracked by the possibility of a disarming first strike, and the need to position Russian forces along a strategy of ‘counter-surprise.’
However, unlike other expensive strategic projects, such as the Poseidon nuclear powered torpedo, Avangard does not contribute to a survivable second strike. Thus there are a few ways to interpret the actual purpose of this weapon. The first is as a retaliatory-meeting strike system to attack high-value targets, i.e. civilian targets with political or economic significance, which will provide some insurance for a counter value strike. The second is that it is a first strike weapon against hard to penetrate targets. Since Avangard is silo based, designed for heavier liquid fueled ICBMs, in the event of strategic attack the boosting missile would not be survivable. It must be fired either first, or in a “launch under attack” scenario, when Russia has confirmed a U.S. launch, but the missiles have not yet impacted.
Avangard may be designed to give Russia’s RVSN the ability to penetrate hard targets, getting around missile defenses, and leveraging greater accuracy to take out well-hardened facilities. That said, from a nuclear warfighting standpoint, this makes Avangard a somewhat specialized, but expensive strategic nuclear weapon. Given how few of these systems Russia is likely to be able to afford, the weapon may offer some targeting advantages, but at a high price relative to the benefits. Another possibility is that this is not a system to get around future missile defenses, but a first-strike system to be used specifically against missile defenses, clearing the way for the rest of Russia’s nuclear deterrent. Even if more accurate and survivable in flight, Avangard is a questionable investment when compared to the numerous road-mobile ICBM systems Russia fields today, including Topol-M and Rs-24 Yars (but then the logic for Russia’s SSBN program is also somewhat circumspect).
Perhaps in the future, Avangard will be deployed on a road-mobile launcher, but as conceived, this system adds little to Russia’s existing large strategic nuclear arsenal. An expensive insurance policy that in no way alters the strategic nuclear balance either today or tomorrow, which is why the reaction in Washington has been so muted. If anything, the United States should thank Russia for investing money in such super weapons, instead of buying large quantities of conventional precision guided munitions.
Moscow has sought to leverage Avangard and similar novel systems to sell the notion of a qualitative arms race to Washington, D.C., hoping to establish a bilateral agenda for summits. Yet while the world is genuinely witnessing a renewed period of nuclear modernization, with qualitatively new or novel weapon systems in development, there is no arms race in progress. The major nuclear powers of today are pursuing distinctly divergent strategies, concepts, and requirements behind their nuclear weapons programs, rather than racing which each other for superiority. This is why Avangard, if completed and deployed, is unlikely to alter strategic military balance or elicit any meaningful response from Washington, D.C.

Anything that can hit the pentagon (command and control centers) or sink a $15 billion Aircraft Carrier 1000 miles from Eurasian shores is a great weapon to have. I’d like to see CNN explain either of those to gung ho jockorama America on the eve of any war. Putin/Kremlin never said these weapons would alter the balance of power, rather that they would create a parity of sorts. US and RF are pursuing different ethos. US is imperialistic power projection of Empire, RF is almost completely defensive in nature, an impenetrable umbrella. RF has no broad or long term imperialist designs outside of its borders, the US is all about the big navy, power projection and empire building (for oil) in fact it is now apparent that they are spread way to thin. Any attack on Russian territory will result in an overwhelming reaction that, as the author points out, cannot be stopped by anything the US or Europeans have. Avangard is a part of that, a multi purpose piece of the jigsaw not a stand alone crushing weapon, Status 6 would be more in that vein.
Please consider…..(!) All of this Hypersonic Wonder-Weapons is ONLY possible on a flat non rotating plane. Start using your brains and think !!
the author is a “good analyst” for the indispensable self believers of the greatness of the Divided States of Zionist America…no doubt….his assessments sound factual and solid…..but…
its a badly needed self deluding presentation for the White House, MSM and the ignorant masses …..to increase the Pentagon budget, boost the self aggrandation ….and sedate the shocking aftermath of Putin’s revelations on March 1st 2018……who wants to believe the Russians are cheating and still incapable and backward….same as 1958 with Sputnik….well, let’s hope Russia does never have to prove the otherwise……
The Avangard can be used as a tactical weapon against naval or fixed targets engaging such targets from thousands of miles away.
The author is myopic in considering the Avangard as a mere strategic weapon.
Avangard, Status 6 nuclear torpedo and nuclear powered cruise missiles are intended to be useful tools in cases of high political and military tensions giving the Russian MOD more flexibility instead of an all out nuclear exchange.
