On March 27, the Indian leadership announced a successful destruction by a missile launched from the ground of a space satellite positioned at an altitude of about 300 km. According to Western media reports, thus the number of countries that have successfully tested anti-satellite weapons technology has increased to four. Western analysts accounting for India’s moves say they have been prompted by fears about China’s military capabilities, which Beijing demonstrated back in 2007. Meanwhile, on January 17 this year, the United States released the first in nine years, review of the country’s Anti-Missile Defense strategy. One of the priority projects involves near-earth orbit combat lasers capable of shooting down intercontinental ballistic missiles (ICBMs). On April 1, it was announced that the United States had blocked the final report of a UN expert group which envisaged measures to prevent the deployment of weapons in outer space. Who is pushing a space arms race?
India’s recent project to test means of destruction of space objects indicate that compared to nuclear weapons, anti-satellite weapons technology needed a much shorter time to spread beyond the “club” of leading players. Significantly, each time the initiative to develop these types of weapons came from Washington. The first tests of the US anti-satellite weapon system were carried out in October 1959. Now, US President Donald Trump’s ambitious plans to deploy combat systems in outer space bring back memories of the infamous ‘star wars’ initiative, which was launched by Ronald Reagan in the early 1980s.
The Strategic Defense Initiative (SDI), proclaimed by President Reagan in March 1983, has been described by many American experts as “a big scam”. Nevertheless, many in the US believe that a new round of arms race, which was prompted by SDI, played a significant role in the economic collapse of the USSR. By the end of the 1990s, the United States claimed to have achieved unparalleled military might and as great political and economic influence in the world. That means that America can openly proclaim a de facto imperial strategy of conduct on the international scene. Washington has made an unequivocal bid for strategic dominance in all areas of human presence, including outer space. As a result, President George W. Bush withdrew from the Anti-Ballistic Missile Treaty.
The withdrawal from the ABM Treaty all but confirmed fears that the United States never stopped developing new space technologies for military purposes. In 2004, it put into operation the ground-based midcourse phase antimissile defense system (GMD),which is designed to combat ICBMs, while its main targets, until recently, were the missile potentials of Iran and North Korea. However, in 2008, the so-called ‘younger sister’ of the GMD interceptor – the SM-3 missile, which is part of the Aegis ship-based missile defense system, – successfully hit a satellite in a 240km orbit. Notably, the potential capabilities of a GMD missile (known as the Ground-Based Interceptor – GBI) are much more significant. Developing a speed of 7-8 kilometers per second, GBI is able to bring the striking combat unit to a height of 6 thousand kilometers. Thus, any satellites in low earth orbit and some spacecraft in high elliptical orbit are within its range.
However, the new “American nationalists” want more than this. By the end of the first year of Trump’s presidency, they managed to secure a “comprehensive revision of the US missile defense policy” and establish provisions for a significant increase in military spending. In place of protection from a “limited ballistic missile strike,” they declared the essentially global goal of covering the territory of the United States and its allies. Finally, in December 2018, Trump issued an order to set up a US Space Command with a view to carry out military operations in space. At present, Pentagon officials are contemplating an appropriate strategy for launching a variety of small and cheap satellites to the low-Earth orbit to track the flight of an ICBM at all its stages without exception. They are considering “non-kinetic means of impacting spacecraft”, a further development of and the launching of dual-purpose satellites, intercepting or disabling foreign spacecraft under the pretext of fighting space debris. According to Western and Russian experts, in the near future the United States plans to look into the possibility of deploying interceptor missiles or laser installations and “cluster groups” of anti-satellite and anti-missile weapons in space.
In addition to military, defense, organizational and bureaucratic measures in guaranteeing a new stage of militarization of space, Washington has been making a number of unambiguous diplomatic steps. In January this year, the United States suspended its participation in the Intermediate-Range Nuclear Forces Treaty and is set on burying it for good in six months. Simultaneously, Washington has jeopardized the last of the existing strategic arms limitation agreements – the Strategic Arms Reduction Treaty (START-3), which, if not renewed, will no longer be valid by 2021. The United States is the main opponent to any international legal initiatives on the prevention of arms race in outer space. Among these initiatives, first of all, is the Russian-Chinese draft treaty on the prevention of the deployment of weapons in outer space, on measures to prevent the use of force against space objects. The treaty is based on a political pledge not to be the first to deploy weapons in space. Thus, the United States has persistently been pursuing the policy of “breaking the instruments of strategic stability” – something that causes the concern of the world’s top players.
Economic and technological competition is becoming the main area of rivalry between the leading powers. We can even say that it is replacing the military-political confrontation. However, everyone understands that even the “theoretical possibility of creating a reliable national missile defense system and the development of missile defense programs” jeopardizes the strategic deterrence potential of any of the nuclear powers. However, the political agenda chosen by the current US leadership is not seen just as another attempt to regain “world supremacy” or maintain unilateral military superiority. Trump has opted for a slow “strangulation” of competitors, a financial and economic “offensive”. He is trying to force unwelcome countries into making a choice between the logic of economic development and the “logic of geopolitical confrontation”, between modern reforms and “security and control priorities”. Apparently, according to Washington’s plan, space systems should become a new policy tool and an effective instrument of pressure to exert on countries that are lagging behind in space technology development.
Russia is well aware of the threats and challenges the new American strategy is fraught with. The US’ attempts to “unceremoniously crush strategic stability in their favor” do not go unanswered. Asymmetrical, but extremely effective due to “advances in military technology”. Moscow’s composure and determination was demonstrated on March 1 last year by President Vladimir Putin, as he spoke of Russia’s brand new strategic weapons systems. At the same time, Russia is not looking for unilateral advantages and is steadily in favor of “thwarting an arms race in outer space.” Moscow is prepared for a parity dialogue “with all states in order to keep outer space free from weapons of any kind – one of the major conditions for ensuring international peace and security,” – the Russian Foreign Ministry said.
In general, as in the 1980s, the current US military space plans have triggered a fairly skeptical reaction from many American and international experts. Like before, the main driving force may not be so much to do with translating these plans into practice as tapping into the huge budgetary funds and an attempt to drag geopolitical competitors into a new technological race. Meanwhile, the dangerous nature of the current US space initiatives is associated with changes in the global parameters of strategic stability. Thus, India’s steps towards the development of space destruction weapons can hardly be directed against the United States. Nonetheless, Washington’s persistent attempts to draw Russia and China into a bilateral military-political confrontation of the type of the Cold War force them to take retaliatory steps.
At the same time, the United States is demonstrating blatant unwillingness to discuss not only a ban, but even measures to limit or establish international control over military activities in space. Given the situation, more and more states that deem national sovereignty a lasting value are taking preventive measures based on the most dramatic scenario for changes in the international strategic environment.

Military Modernization of ASEAN States: The New Agenda
The discourse about the international security and defense affairs have always been impregnated with the dynamics of security dilemma. Even today, when complex interdependence has connected states in multiple ways, the global politics still tends to favor Machiavellian norms. Therefore, it is forcefully propagated that the security of the state depends upon the strength of their armament. Apparently, it sounds perfectly reasonable, to have the recent generations of arms in abundant quantity to deter the ‘enemy. But what if a state has no enemy? Or at least does not have any immediate enemy in the general sense of the term. Should such a state focus its resources to build a mighty defense sector and take part in an arms race? The answer that might pop in our minds is No. Unfortunately, this is true in the case of South East Asian states. In the last few years, the ASEAN states’ military spending has nearly doubled. Most notably, Thailand and Indonesia’s military budget has been snowballing at the rate of 10% on a year by year basis. It is interesting to note that Vietnam arms import has spiked 700% over a decade, making it one of the top 10 purchaser of arms. Other ASEAN states have been increasingly importing fighter jets, frigates, helicopters, submarines and the like.
The emerging situation in the region could be analyzed from these three different perspectives. Firstly, South East Asian states have increased their military spending as a consequences of US withdrawal from the region and mounting concerns about China’s growing regional as well as global influence. As ASEAN states generally enjoy cordial relations among themselves and the spirit of regionalism is very much prevalent in both their bi and multi-lateral relations. Besides, these states have, by and large, remained peaceful in world affairs. Therefore, considering this first perspective has its own problems, it might be true to some extent, that the recent surge in spend spending is aimed at countering China, with which they share friendly ties, or filling some security void. Secondly, some experts argue that south East Asian states’ military spending is according to their GDP rate, and has remained stable over the period. Therefore, this ‘surge’ is normal. Lastly, according to some scholars, we need to look at what these states are actually buying to understand the whole situation. These scholars argue that, these states have been spending the money on ‘modernizing’ their armament that have, otherwise, been hardly functional for years. So, for this standpoint, this surge in military spending is nothing more than normal efforts to modernize state weaponry.
Nonetheless, this is where the actual problem lies. Why should states seek to modernize their weaponry when there is no such apparent reason and when this weaponry has been “barely functional for years”? Armaments, like other machineries, need constant maintenance, supervision and regulation. And all of this requires a lot of resources. Even if a state’s military spending is in accordance with its GDP, armament or its modernization, whether qualitatively or quantitatively, must not be ‘justified’. Since cold war, international politics has seen many disarmament efforts, be it conventions on chemical or biological weapons, denuclearization zones, Arms trade treaty or Nuclear Non-proliferation treaty. It is a high time that instead of making it customary to have some modern armament, states must come together to break this norm. Particularly, South East Asian states, that have no deeply embedded antagonism, neither within the region nor outside it, could have reversed the norm of owing “modern military weaponry”, that would most likely again remain ‘barely functional for years’ on end.
Moreover, as previously mentioned, what these states have been importing is telling. However, how this modernization in armament has been reoriented is equally important, as many of the regions military strategies are shifting their focus away from countering insurgency to external defense and conventional warfare. While domestic factors do play a key role here. For instance, Thailand doubled its military spending after the military coups of 2006 and 2014. And Myanmar has justified its arms buildup on the pretext of having to deal with various insurgent groups within the state. Though particularly in Myanmar’s case, instead of spending heavily on military and committing gross atrocities against its very own Rohingya community, it should have provided shelter to them.
Although various studies refute that there is any instrumental link between armament and warfare. But given that, when such efforts are aimed at strengthening capabilities for external warfare, it is likely that it might spike some mutual distrust at some point in the future. But it’s not simply the matter of the conflict that ‘might emerge’, the problem here is, an undaunted prevalence of spending on weapons at international level that has quietly legitimized, justified and warranted the buying and selling of lethal weapons. So much so that, such a state of affair is usually vindicated and rationalized into a ‘broader context’ of necessities of owning vast weaponry to secure stability. Sadly, such broader context is rarely ‘broad enough’ to include human rights and humanitarian perspectives in the contours of world politics.
The South East Asian States are engulfed in an unending arms race for their survival. To sum up, the discourse on international security and defense that focuses so much on arms buildup needs to be realigned with the new realities of the time. South East Asian states should come up as a norm changer by diverting their resources from extensive defense spending to the human resource development. Progress and development in economy, society, science and technology will pay off in much better ways than investment of precious resources in arms race.
Gambling with the Nuclear Button in South Asia
Over the last decade, India’s rapid expansion of its conventional and nuclear arms capabilities have presented a worrying dilemma with regard to the South Asian region’s security and stability. This holds especially true considering how its clear ambitions to translate its economic rise into a menacing projection of hard-power have remained on full display particularly under the BJP’s tenure. While many observers have come to regard these ambitions as the ruling party simply pandering to the populist vote, the steady consistency with which this policy has been carried throughout the last decade represents a dangerous mindset that appears to have become deeply engrained within India’s civil and military bureaucracy. This mindset and its obsession with external hard-power is further evident in the institutionalization of concepts such as Cold Start and Surgical Strikes both of which have been formalized as part of the Indian State’s official policy as well as its military doctrine.
For instance, both these concepts have been defined at length in the Joint Doctrine of the Indian Armed Forces that was released in April 2017 as well as the Indian Army’s Land Warfare Doctrine that was published the following year. As a clear signal of its regional ambitions, both these documents have also unmistakably identified Pakistan and China as India’s principle source of threats. In order to counter these threats these same documents advocate the development of military strategies aimed at pre-set and purportedly restrained instances of minimal force projection that allow India to remain well within the nuclear threshold. This threshold that currently pervades throughout India’s strategic rivalry with both Pakistan and China is arguably the key to maintaining the delicate strategic balance that currently pervades throughout the South Asian region. A region that otherwise comprises of a key locus for the world’s future economic growth and development.
However, the fact that India’s stated policy is to radically alter this strategic balance represents a dangerous mindset, that is based more on its own solitary potential for growth rather than that of the wider region. In what can be termed as nothing short of a myopic outlook to the entire region’s trajectory, India’s efforts at enhancing its force projection capabilities and tilting this delicate balance in its favor is replete with risks. Risks that are in turn deeply rooted in unqualified and broad-ranging premises that assume both Pakistan and China to remain as passive spectators to its aggressive military posturing.
Hence, by constantly aiming to raise the nuclear threshold, the above-mentioned concepts of cold start and surgical strikes are in essence aimed at downplaying the risks of a potential nuclear exchange in South Asia. From a purely rational perspective, this policy while appearing as nothing short of madness, openly flirts with the grave sanctity of the escalation ladder on which the region’s strategic planners and decision-makers rely on when calculating the possibility of a potential nuclear first-strike. As a Nuclear Weapons’ State (NWS) that shares disputed borders with two other Nuclear Weapons’ states, India’s dangerous posturing is thus heavily dependent on it being perceived as a responsible Nuclear power to both Pakistan and China. However, it is this perception of being a responsible NWS which India is actively working to negate as evident in its leaders’ jingoistic saber-rattling.
These include regular statements by Indian leaders in which by openly alluding to the death and annihilation of its strategic rivals, one can witness a certain normalization of nuclear brinkmanship which has become a modus operandi of sorts for Prime Minister Modi. Similar allusions to India possessing the ‘Mother of all Bombs’(in the form of perhaps thermo-nuclear weapons) also represents a kind of posturing that is aimed at upending the status-quo and provoking a response. These statements when coupled with the Indian military-bureaucracy’s clear allusions to reneging its No First Use policy, have further led to even greater ambiguity with regard to India’s strategic calculus. As a result, all these instances represent a dangerous precedent being set for what is considered as ‘acceptable risk’ by India’s strategic planners.
While such negative posturing has been successful in communicating India’s increased risk-appetite to its strategic rivals, what’s unclear is whether these risks are based on a credible deterrence capability or quite simply, the egoistic hubris of its elected leaders and bureaucratic machinery. In what can perhaps only be described as an infantile staring contest; in which one’s sole chance of survival from a nuclear holocaust is counting on the other party’s willingness to blink first, the Indian state’s projection of hard-power seems to be based on more of a wild gamble than the well-thought out contingencies of a major nuclear power.
Hence, with the Indian leadership’s official preference of a defence policy steeped in the risks of nuclear exchange, the merits of institutionalizing its approach to brinkmanship is something that appears downright non-sensical in this day age. Especially during a time where economic growth and human development remain as some of the region’s most pervasive challenges, India’s aggressive regional posturing hark back to the politics of a bygone era in times that otherwise require a visionary approach to fostering regional peace and stability.
The Global Hypersonic Race
Prominent Western politicians have launched a global discussion about the risks associated with Russia developing hypersonic weapons. Arms control experts are attempting to estimate the potential of these new weapons, but attempts at this stage are hindered by the absence of important technical data and the lack of specialized terminology in this field.
The discussion of the threats posed by hypersonic weapons was triggered by President of the Russian Federation Vladimir Putin, who in his address to the Federal Assembly on March 1, 2018, described the impressive capabilities of Russia’s new Avangard and Kinzhal strategic missile systems as follows: “The glide vehicle strikes its target like a meteorite, like a fireball, with its surface temperature reaching between 1600 and 2000 degrees Celsius, while remaining completely controllable at the same time.”
Federal Minister for Foreign Affairs of Germany Heiko Maas attempted to take the lead in discussing the destabilizing new technology. In March 2019, he hastily organized the “2019. Capturing Technology. Rethinking Arms Control” international conference in Berlin. In his opening speech, Maas said: “Manoeuvrable missiles travelling at many times the speed of sound barely leave time for considered human responses. The fact that we are not just talking about science fiction here is demonstrated by Russia’s announcement that the first Avangard systems will be entering service this year. I would therefore also like to seize this conference as an opportunity to establish an international missiles dialogue that takes into account both the challenges posed by new technologies and the dangers of their proliferation. The experts gathered here today could form the backbone of this kind of global Missile Dialogue Initiative.”
However, the subsequent discussion at the conference demonstrated that many of the participants were unfamiliar with the topic of hypersonic weapons. Recognized experts on missile control proved unprepared to hold a substantive conversation about hypersonic technology. As a result, the dialogue was reduced to discussing the INF Treaty.
At the end of the conference, the ministers of foreign affairs of Germany, the Netherlands and Sweden signed a political declaration stressing the “need to build a shared understanding of how technologically enhanced military capabilities may change the character of warfare and how this will influence global security.”
In the United States, where hypersonic technology has already been developing at a rapid pace, including as part of the Prompt Global Strike programme, Putin’s announcement was used as a pretext for investing more in the Pentagon’s projects. “We have lost our technical advantage in hypersonics [but] we have not lost the hypersonics fight,” said Vice Chairman of the Joint Chiefs of Staff General Paul Selva. Meanwhile, Under Secretary of Defense for Research and Engineering Mike Griffin, for his part, has identified hypersonics as his top priority and called for an industrial base to be established that could support the development and production of thousands of deterrence hypersonic vehicles.
Mike White, the Pentagon’s assistant director for hypersonics, announced that the department had a three-step plan for the development of hypersonic weapons that involves investing generously in offensive capabilities, then in defensive systems, and finally, at least ten years from now, in reusable airborne hypersonic vehicles. The Pentagon’s spending on hypersonic projects has increased from $201 million in 2018 to $278 million in 2019, and the overall cost of the program is estimated at $2 billion.
China has been no stranger to this “war of words,” with several fantastic reports emanating from the country about “successful tests of hypersonic flight vehicles,” the creation of a material capable of withstanding temperatures of up to 3000 degrees Celsius, and even the development of a universal engine that can accelerate a vehicle from zero to hypersonic flight. Japan has stated its intent to create a High-Speed Gliding Missile, an equivalent of Russia’s Avangard.
Minister of the Armed Forces of France Florence Parly has announced the country’s plans to use the ASN4G supersonic air-to-surface cruise missile as the baseline for the V-MaX supersonic glider that could travel at a speed of over 6000 km/h. The project is being led by ArianeGroup, a joint venture between Airbus and Safran, and the first test flight could take place in late 2021.
In the meantime, the global expert community has yet to come up with a clear scientific definition for the term “hypersonic vehicle.” Hypersonic flight is conventionally understood to mean atmospheric flight at speeds higher than Mach 5, that is, five times the speed of sound. The second important feature of a hypersonic aircraft is its ability to maneuver with the use of aerodynamic forces, rather than merely adjusting the target accuracy. This entails longer atmospheric flight times and greater susceptibility to the destructive factors associated with atmospheric flight.
At present, only a handful of countries are close to creating effective hypersonic weapons. Hypersonic weapons engineers are faced with some very unique technical challenges. To begin with, there is the problem of ensuring controlled and sustained flight in a rarefied atmosphere whose density varies with altitude. Among other things, this creates difficulties for propulsion systems that consume oxygen.
Also, the friction created by the hypersonic airflow around the vehicle’s surface generates a sheath of ionized plasma, with the nose fairing temperature reaching up to 3000 degrees Celsius. Even vehicles made of ultra-heat-resistant alloys or composites lose their shape and original aerodynamic characteristics due to the heating and ablation. For example, the U.S. Lockheed SR-71 Blackbird high-altitude supersonic reconnaissance aircraft would become 10cm longer in flight owing to thermal expansion, and fuel would seep from its seams on landing.
Controlling a hypersonic vehicle from launch to target impact is a separate problem, as the plasma sheath blocks radio signals. Solving this problem requires complex and expensive research. Even US engineers have not yet found a solution to this problem.
Another challenge is linked to the fact that the plasma sheath significantly complicates navigation, which for a strike vehicle must be autonomous, prompt and very accurate. Plasma makes electro-optical and radio-frequency homing impossible. Inertial navigation systems cannot provide the required accuracy at long distances. A solution to this problem has yet to be found.
The traditional types of aviation fuel (jet fuel and methane) are unsuitable at hypersonic speeds. A hypersonic vehicle needs a special kind of fuel. Also, a universal propulsion engine capable of accelerating a vehicle from zero to hypersonic speeds has not yet been created. At present, militaries have to make do with rocket boosters or supersonic aircraft to accelerate vehicles to speeds at which their supersonic combustion ramjet engines can be engaged.
When it comes to the flight mode, there are three different types of hypersonic vehicles. The first type is an unpowered glide vehicle, which rides a ballistic missile to an altitude of approximately 100km, separates, and performs a maneuverable flight in the upper atmospheric layer at speeds between Mach 8 and Mach 28. By skip-gliding along the atmosphere like a skipping stone along the water surface, such a vehicle can increase its flight range by several times. The second type is a scramjet-powered vehicle, which can only fly in the atmosphere because its engine needs oxygen. The third type is a quasi-ballistic or semi-ballistic missile that mainly follows a shallow ballistic trajectory but can also maneuver to evade enemy missile defenses. One example here is the Russian Iskander-M missile, which flies at hypersonic speeds of between 2100 and 2600 m/sec (Mach 6 to Mach 7) at an altitude of 50km.
Experts sometimes use the term “aeroballistic.” However, this definition is not applied to the speed of flight, but rather to the mode of travel: namely, it implies a combined mode of partially traveling along a ballistic trajectory and partially employing aerodynamic control surfaces and jet vanes for steering. An aeroballistic vehicle does not necessarily have to be hypersonic, as the term can also be applied to slower vehicles, although it is now widely used in the context of the hypersonic Kinzhal and Iskander-M missiles.
Hypersonic vehicles have one distinct feature which traditional exo-atmospheric ballistic missiles do not. While most ballistic missiles develop speeds of dozens of Machs (i.e., they also travel at hypersonic speeds), they are not described as hypersonic unless they or their warheads are capable of aerodynamic maneuvering in the atmosphere.
Some ballistic missile warheads are capable of terminal trajectory corrections. They are not classed as hypersonic vehicles, since the purpose of their maneuvering is not to increase the flight range or evade an anti-missile attack, but merely to reduce the circular error probable (CEP).
All hypersonic vehicles can be subdivided into five categories depending on their mission:
- Manned aircraft (the first and so far only example here is the U.S. North American X-15, which set the world airspeed record of Mach 6.72 in 1967)
- Unmanned vehicles (mainly experimental projects such as the Boeing X-43, which reached Mach 9.6 in 2004)
- Scramjet-powered hypersonic missiles (such as the Russian 3M22 Zircon)
- Hypersonic glide vehicles (the Russian Avangard or the U.S. Advanced Hypersonic Weapon)
- Air- or ground-launched spaceplanes (the Soviet Buran and U.S. Space Shuttle vehicles, which reach speeds of Mach 25 upon re-entry).
Military hypersonic vehicles fall into the following three categories:
1. Reconnaissance vehicles
At present, only one purely reconnaissance hypersonic vehicle is known to be under development: the Lockheed Martin SR-72, which can theoretically travel at speeds of up to 7400 km/h. This vehicle is expected to be better at monitoring mobile missile systems than reconnaissance satellites. It could also eventually be equipped to carry a charge for a pinpoint strike.
Another experimental orbital hypersonic vehicle is the Boeing X-37B. Although little is known about its intended mission, it could also serve as a reconnaissance platform.
2. Hypersonic kill vehicles
Scramjet-powered hypersonic cruise missiles that can be launched by an aircraft, a sea-surface ship or a submarine (the Russian 3M22 Zircon or the U.S. X-51A Waverider, which is currently under development) can be used to destroy enemy missile early warning systems, anti-aircraft and anti-missile defenses, airfields, hardened command posts and critical facilities.
Glide vehicles (the Russian Avangard; the U.S. Lockheed Martin Falcon, HIFiRE and HSSW/TBG [High-Speed Strike Weapon/Tactical Boost Glide]; and the Chinese WU-14/DF-ZF) are primarily intended as nuclear strike weapons.
Quasi-ballistic missiles (the Russian Kinzhal and Iskander-M; the Indian Shaurya tactical missile; and the Chinese DF-21D anti-ship ballistic missile) are relatively difficult to detect by radar thanks to their shallow trajectory. Their warheads can change trajectory, so enemy missile defenses cannot calculate the exact target, and the warhead’s maneuverability considerably complicates interception.
3. Hypersonic interceptors
These are surface-to-air missiles designed to intercept ballistic missile warheads, normally in their terminal, atmospheric phase of trajectory. The most advanced interceptors can engage ballistic missiles at exo-atmospheric altitudes and even shoot down low-orbit satellites.
To stand a chance of intercepting a ballistic target, an interceptor must not only develop a high speed, but also launch promptly and maneuver actively. U.S. RIM-161 SM-3 Block IIA missiles of the Aegis Ballistic Missile Defense System can travel at speeds of up to Mach 15.25; the Russian S-400 48N6DM missiles have a speed of Mach 7.5, and the future S500 77N6-N1 missiles will be able to reach speeds of up to Mach 21.
Advantages of Hypersonic Missiles
Hypersonic missiles have several obvious advantages over ballistic missiles. First, they follow significantly shallower trajectories, so ground-based radars detect them later into the flight. Second, thanks to their maneuvering, high speed and unpredictable trajectory, the enemy cannot be certain of the hypersonic vehicle’s target, whereas the trajectory of a ballistic missile is currently fairly easy to calculate. Third, ballistic missile interception experiments have been conducted since the 1960s, and there are plenty of reports on successful trial intercepts. However, intercepting a high-speed maneuvering atmospheric target is extremely difficult and is believed to be impossible at present. Also, the mass production of hypersonic vehicles is expected to be cheaper than that of ballistic missiles. Despite the challenges associated with developing scram engines, such jets have virtually no moving parts and their cross-sections represent special configuration tubing. According to analysts at the U.S. company Capital Alpha Partners, “If hypersonic weapons can be produced with unit costs of $2 million, or less, they will impact some of the outyear weapons plans. A weapon that travels at Mach 5, or faster, and that can maneuver will see strong U.S. demand in the later part of this decade.” Finally, the kinetic energy of a hypersonic missile is so high that its release will be enough to destroy certain types of targets even without using a charge. This gives experts reason to state that hypersonic missiles might become an alternative to nuclear weapons in certain situations.
Shortcomings of Hypersonic Missiles
As for the shortcomings of hypersonic missiles, experts point out that they cannot offer high target accuracy because it is almost impossible to fit such a missile with a homing head, and its high speed will result in an increase in targeting error. A hypersonic vehicle is believed to have a CER of between 30 and 50 meters. Furthermore, high-speed missiles will have a large infrared signature due to frictional skin heating, making them easily detectable by IR sensors. Designers will need to find a compromise between the high impact speed and the high probability of standoff detection. Also, a scramjet-powered missile must be initially accelerated to a speed of about Mach 3. This complicates the use of such weapons, which require a rocket booster or a high-speed air-launch platform. Experts believe that, due to a plethora of technological problems, hypersonic weapons currently have a relatively limited effective range (some 1000km for scramjet-powered missiles). However, the veil of secrecy surrounding this type of weaponry provokes rumors and excessive fears, and this destabilizing factor could prompt the enemy to resort to a pre-emptive strike.
Challenges for International Security and Stability
The U.S. expert community has carefully studied the potential of Russian hypersonic weapons in terms of how they could affect the balance of forces and concluded that, in general, they do not pose an existential threat to major nuclear powers. Thus, fitting Avangard missiles with glide vehicles will not increase the size of the Russian nuclear arsenal, nor will it extend the effective range of the missiles, their range of action or their strike speed. The United States and other nuclear powers will still be able to respond to a Russian nuclear attack.
U.S. experts admit that maneuvering hypersonic vehicles are almost impossible to intercept. However, given that the U.S. missile defense system has very limited intercept capabilities when it comes even to Russian ballistic missiles, the introduction of Avangard hypersonic missiles changes little in the nuclear war scenario. For the United States, this is more of a technological challenge, with which both the Pentagon and the White House are fairly unhappy. Dominance in military technology has remained a priority for the United States for decades, ever since the launch of the first Soviet satellite. Therefore, the news of Russia’s hypersonic achievements does not sit well with Washington. At the same time, it has provided the United States with an opportunity to study the possibility of extending missile defense to near space. Megawatt laser weapons are believed to be capable of destroying both ballistic and hypersonic missiles. The current level of U.S. technology already allows for equipping different types of ground transport with lasers generating in excess of 50kW of power, while sea-based lasers can generate over 150kW. Under the current trend, laser power increases tenfold every three years. In this sense, within five years, we can expect U.S. laser technology to reach a level that where the Pentagon may be confident in the possibility of building lasers that are capable of shooting down hypersonic devices. The next step will then be to deploy laser weapons in the Earth’s orbit.
In light of the above, the emergence of hypersonic weapons will introduce a number of destabilizing factors for international security. First, countries possessing such weapons will have an asymmetric advantage over other developing countries. Second, it will trigger the deployment of the space-based laser component of the missile defense system. Third, it will provoke a new global arms race, including with regard to laser weapons, hypersonic anti-missile systems, cyber-weapons, railguns and unmanned delivery platforms for strike weapons. Moreover, for non-nuclear powers, hypersonic missiles may become a serious instrument of deterrence or power projection. It should also be noted that hypersonic missiles could be used in a pre-emptive strike against an enemy whose main weapons are situated within their effective reach (at present, within a radius of up to 1000km). That is, the deployment of hypersonic weapons can be considered as a critical threat to the country’s immediate neighbors. Finally, there are global risks to the Missile Technology Control Regime (MTCR). The secret hunt for missile components such as fuel, alloys, electronics and airframe blueprints has never stopped. In the new environment, even those countries that are signatories to the MTCR are interested in obtaining prompt global strike technologies.
The current leaders of hypersonic weapons research are, in addition to Russia, the United States and China.
Despite its ambitious statements, China has not yet rolled out a reliable prototype of a hypersonic vehicle. Chinese engineers have developed the YJ-12 supersonic anti-ship cruise missile, but the country’s military currently only has subsonic ground-based cruise missiles in service. It may be the case that Beijing hopes to leap from subsonic straight to hypersonic, skipping supersonics altogether.
China is believed to be working on at least two hypersonic programs. Since 2014, it has been testing the DF-ZF (dubbed Wu-14 in the United States) hypersonic glide vehicle complete with the DF-17 medium-range ballistic missile for the launch vehicle (eventually to be replaced by the DF-31 missile). The second project, the air-launched CH-AS-X-13 missile, is primarily intended against aircraft carriers. According to a representative of the Chinese Academy of Engineering, the Institute of Mechanics has created a turbine-based combined-cycle engine capable of accelerating a vehicle to Mach 6.
As part of the High Speed Strike Weapon (HSSW) program, the Defense Advanced Research Projects Agency (DARPA) and the United States Air Force are working on three hypersonic concepts. The Tactical Boost Glide (TBG) combat vehicle riding a solid-fuel rocket booster, under development by Lockheed Martin and Raytheon, is planned as an equivalent to Russia’s Avangard. The Boeing Hypersonic Air-Breathing Weapon Concept (HAWC) will have a combined-cycle engine (the turbine will accelerate the vehicle to Mach 2, after which the scramjet will further propel it to hypersonic speeds). According to some reports, the vehicle may be reusable. Northrop Grumman Corporation is working to design the combined-cycle Advanced Full Range Engine (AFRE) for HAWC under a contract with DARPA. Finally, the reusable unmanned craft under development as part of the HyRAX project and the XS-1 Experimental Spaceplane program will be used as an inexpensive launch vehicle to insert dual-use satellites into low-Earth orbits.
The HSSW program is aimed at designing and testing a hypersonic strike vehicle by 2020. The key specifications include speeds of Mach 6 to 10, an effective range of over 1000km, a CEP of under 5m and a variety of warhead types (penetrator, HE-fragmentation or cluster).
The U.S. Air Force Research Laboratory is looking into the possibility of creating a combined-cycle propulsion system for reusable vehicles, including by way of integrating scramjets with reheated bypass turbojets.
In addition to DARPA, hypersonic weapons are being developed by the United States Army Space and Missile Defense Command in conjunction with the Sandia National Laboratory under the Advanced Hypersonic Weapon project, which calls for the creation of a hypersonic glide vehicle with a precision terminal guidance system.
Russia’s breakthrough in the hypersonic weapons race may have shaken the global balance of forces, but it has not reshaped it. The United States is not far behind Russia technologically, and may even be ahead in certain aspects of hypersonic weapons, including when it comes to making combined-cycle or hybrid propulsion systems for hypersonic vehicles that would allow a reusable reconnaissance/strike vehicle to be created. Nevertheless, the Russian achievements came as an unpleasant surprise for all the leading world powers.
The situation appears different for those nations that do not command massive nuclear arsenals. The Russian example opens a window of opportunities for them. Hypersonic weapons may appear to be an excellent solution for ensuring a decisive military advantage over a technically lacking adversary. Those countries lagging behind in the arms race may perceive hypersonic weapons as a critical and potentially disarming threat to an unfriendly neighbor.
In the art of war, uncertainty often drives progress. As the leading analytical centers are working to collect relevant information and understand the scale of possible threats, politicians and militaries are approving investment in new defense programs. A new item on defense budgets around the world has appeared.
