A Perpetual State of Competition: US-China-Russia

The US Secretary of Defense stated in September 2020 that America’s air, space and cyber warriors “will be at the forefront of tomorrow’s high-end fight.” That means confronting near-peer competitors China and Russia. That means shifting the focus from defeating violent extremist groups to deterring great power competitors. It means fighting a high-intensity battle that combines all domains of warfare. “In this era of great power competition, we cannot take for granted the United States’ long-held advantages,” Esper said. 

The last time an enemy force dropped a bomb on American troops was in the Korean War. “China and Russia, seek to erode our longstanding dominance in air power through long-range fires, anti-access/area-denial systems and other asymmetric capabilities designed to counter our strengths,” he said. “Meanwhile, in space, Moscow and Beijing have turned a once peaceful arena into a warfighting domain.” China and Russia have placed weapons on satellites and are developing directed energy weapons to exploit U.S. systems “and chip away at our military advantage,” he said.

Russia, China, North Korea, Iran and some violent extremist groups also look to exploit cyberspace to undermine U.S. security without confronting American conventional overmatch. “They do this all in an increasingly ‘gray zone’ of engagement that keeps us in a perpetual state of competition,’ the secretary said…The fiscal 2020 Defense Department research and development budget is the largest in history, he said, and it concentrates on critical technologies such as hypersonic weapons, directed energy and autonomous systems. 

“In the Air Force, specifically, we are modernizing our force for the 21st century with aircraft such as the B-21, the X-37 and the Next Generation Air Dominance platform,” Esper said. “Equally important, we are transforming the way we fight through the implementation of novel concepts such as Dynamic Force Employment, which provides scalable options to employ the joint force while preserving our capabilities for major combat.”

To realize the full potential of new concepts the department must be able to exchange and synchronize information across systems, services and platforms, seamlessly across all domains, he said. “The Department of the Air Force is leading on this front with the advancement of Joint All-Domain Command and Control,” Esper said.  This concept is part of the development of a Joint Warfighting concept that will drive transition to all-domain operations, he said. “

For these breakthroughs to succeed in any future conflict … we must maintain superiority in the ultimate high ground — space,” Esper said…In collaboration with academia and industry, the Air Force’s AI Accelerator program is able to rapidly prototype cutting-edge innovation,” Esper said. One example of this was the AI technology used to speed-up the development of  F-15EX.

A Hypersonic Death: The Race to Develop Hypersonic Weapons

For decades, the U.S. military—and its adversaries—have coveted missiles that travel at hypersonic speed, generally defined as Mach 5 (5 times the speed of sound) or greater . Intercontinental ballistic missiles (ICBMs) meet that definition when they re-enter the atmosphere from space. But because they arc along a predictable ballistic path, like a bullet, they lack the element of surprise. In contrast, hypersonic weapons such as China’s waverider maneuver aerodynamically, enabling them to dodge defenses and keep an adversary guessing about the target.

The US Department of Defense (DOD) is leading a new charge, pouring more than $1 billion annually into hypersonic research. Competition from ambitious programs in China and Russia is a key motivator. Although hype and secrecy muddy the picture, all three nations appear to have made substantial progress in overcoming key obstacles, such as protecting hypersonic craft from savage frictional heating. Russia recently unveiled a weapon called the Kinzhal, said to reach Mach 10 under its own power, and another called Avangard that is boosted by a rocket to an astonishing Mach 27. China showed off a rocket-boosted hypersonic glide vehicle (HGV) of its own, the Dongfeng-17, in a recent military parade. The United States, meanwhile, is testing several hypersonic weapons. “It’s a race to the Moon sort of thing,” says Iain Boyd, an aerospace engineer at the University of Colorado, Boulder. “National pride is at stake.”

China’s military sees hypersonic weapons (as well as cyberwarfare and electromagnetic pulse strikes) as an “assassin’s mace”: a folklore term for a weapon that gives an advantage against a better-armed foe. If tensions were to spike over Taiwan or the South China Sea, for instance, China might be tempted to launch preemptive strikes with conventional hypersonic weapons that could cripple U.S. forces in the Pacific Ocean.For now, maneuverability at hypersonic speeds makes the weapons nearly impossible to shoot down—unstoppable…

At hypersonic speeds,  “You’re flying under extraordinary conditions”—extreme velocities, forces, and temperatures.  At hypersonic  speeds “temperatures start to get high enough to worry about… A vehicle’s survival requires resilient superalloys and ultra–high-temperature ceramics. And perhaps novel coolants…

Other nations are chasing the trio of leaders—or teaming up with them. Australia is collaborating with the United States on a Mach 8 HGV, and India with Russia on a Mach 7 Hypersonic Cruise Missile (HCM). France intends to field an HCM by 2022, and Japan is aiming for an HGV in 2026.

THE United States is largely defenseless against such weapons, at least for now, in part because it can’t track them…To remedy that shortcoming, the Pentagon plans to launch hundreds of small satellites with sensors capable of tracking heat sources an order of magnitude cooler than rocket boosters. The full Hypersonic and Ballistic Tracking Space Sensor network could be up and running by 2030, he adds. (The satellites would also be used to help guide U.S. hypersonic weapons.)  Once you have such sensors, “we can find a way to build the interceptors…Interceptors could destroy a hypersonic vehicle either by colliding with it or by detonating a warhead nearby. But Missile Defense Agency (MDA) is also exploring using directed energy: lasers, neutral particle beams, and microwaves or radio waves.

HyperSonic Gliders: Arms Race at the Speed of Sound

Hypersonics are like missiles that travel at over five times the speed of sound, but are able to manoeuvre in mid-flight, making them much harder to track and intercept than traditional projectiles.  France is the fourth of the five permanent UN Security Council members to join the so-called “stealth by speed” contest, after China, Russia and the United States.  “We have decided to issue a contract for a hypersonic glider”–V-MaX (Experimental Manoeuvering Vehicle)–that can travel at over 6,000 kilometres per hour, Defence Minister Florence Parly said last week, promising a test flight by the end of 2021.

In March 2018, Russian President Vladimir Putin stunned Western military analysts – and many in Russia – by unveiling plans for a new arsenal of hypersonic weapons which he said would render missile defence systems obsolete….A few months later US President Donald Trump threatened to walk away from a key arms control treaty with Moscow.

Hypersonic gliders would be carried to the end of the earth’s atmosphere by a launch vehicle and would then “glide” back to a target on the ground. “The goal is high-speed manoeuvrability. That’s how it differs from a ballistic trajectory,” the French government’s defence procurement and technology agency (DGA) said.  “Once the initial speed is reached, we can play with speed and altitude to move up and down, to the left and to the right, creating a trajectory that is more difficult to intercept,” it said…

In December 2018, the Kremlin touted the capabilities of its new hypersonic glider, aptly named “Avanguard”.  The Kremlin said that in tests, the intercontinental projectile reached 27 times the speed of sound – 33,000 kilometres per hour, or Mach 27.  “At this speed, not a single intercepter missile can shoot it down,” Deputy Prime Minister Yury Borisov boasted.  China has also reportedly carried out several successful tests since 2014 of a glider that can reach speeds of between Mach 5 and Mach 10.

The Right Way to Steal

Chinese government hackers have compromised the computers of a Navy contractor, stealing massive amounts of highly sensitive data related to undersea warfare — including secret plans to develop a supersonic anti-ship missile for use on U.S. submarines by 2020, according to American officials.   The breaches occurred in January and February  2018, the officials said… The hackers targeted a contractor who works for the Naval Undersea Warfare Center, a military organization headquartered in Newport, R.I., that conducts research and development for submarines and underwater weaponry.

Taken were 614 gigabytes of material relating to a closely held project known as Sea Dragon, as well as signals and sensor data, submarine radio room information relating to cryptographic systems, and the Navy submarine development unit’s electronic warfare library…This fact raises concerns about the Navy’s ability to oversee contractors tasked with developing ­cutting-edge weapons.

For years, Chinese government hackers have siphoned information on the U.S. military, underscoring the challenge the Pentagon faces in safeguarding details of its technological advances. Over the years, the Chinese have snatched designs for the F-35 Joint Strike Fighter; the advanced Patriot PAC-3 missile system; the Army system for shooting down ballistic missiles known as Terminal High Altitude Area Defense; and the Navy’s new Littoral Combat Ship, a small surface vessel designed for near-shore operations, according to previous reports prepared for the Pentagon.  In some cases, suspected Chinese breaches appear to have resulted in copycat technologies…

Investigators say the hack was carried out by the Chinese Ministry of State Security, a civilian spy agency responsible for counterintelligence, foreign intelligence and domestic political security. The hackers operated out of an MSS division in the province of Guangdong, which houses a major foreign hacking department….

In September 2015, in a bid to avert economic sanctions, Chinese President Xi Jinping pledged to President Barack Obama that China would refrain from conducting commercial cyberespionage against the United States. …Both China and the United States consider spying on military technology to fall outside the pact.

Leveling: How a 5,000 km/h Speed Feels on Earthlings

Hypersonic missiles [weapons faster than the speed of sound]— specifically hypersonic glide vehicles and hypersonic cruise missiles — are a new class of threat because they are capable both of maneuvering and of flying faster than 5,000 kilometers per hour. These features enable such missiles to penetrate most missile defenses and to further compress the timelines for a response by a nation under attack.

Hypersonic missiles are being developed by the United States, Russia, and China. Their proliferation beyond these three could result in other powers setting their strategic forces on hair-trigger states of readiness. And such proliferation could enable other powers to more credibly threaten attacks on major powers.  The diffusion of hypersonic technology is under way in Europe, Japan, Australia, and India — with other nations beginning to explore such technology. Proliferation could cross multiple borders if hypersonic technology is offered on world markets.

There is probably less than a decade available to substantially hinder the potential proliferation of hypersonic missiles and associated technologies. To this end, the report recommends that (1) the United States, Russia, and China should agree not to export complete hypersonic missile systems or their major components and (2) the broader international community should establish controls on a wider range of hypersonic missile hardware and technology.rs.

The unavoidable requirement is for the United States, Russia, and China to agree on a nonproliferation policy. France could play a key role in bringing other governments into agreement on a broader control policy.

The technical and economic barriers to developing hypersonic technology are great enough to add to the effectiveness of a nonproliferation policy.

A two-tiered approach to containing the spread of hypersonic systems and components appears to be the most promising.

First, we recommend a policy of export denial for complete hypersonic delivery vehicles and enough major subsystems to effectively provide access to complete hypersonic missiles.

Second, given dual-use concerns, we also recommend a policy of case-by-case export reviews for scramjets and other hypersonic engines and components, fuels for hypersonic use, sensors, navigation, and communication items for hypersonic flight, hypersonic flight controls, design tools and modeling for such uses, and ground simulation and testing for hypersonic systems.

The necessary first step is for the United States, Russia, and China to agree not to export complete hypersonic missiles or their major subsystems.

Hypersonic Weapons

Payloads on hypersonic aircraft, whether they are weapons or sensors, could reach their destination within minutes, rather than hours, said Mark Lewis, former chief scientist of the Air Force and now director of the Science and Technology Institute at the Institute for Defense Analyses, a federally funded research-and-development center.  Hypersonic speed is generally defined as beginning at Mach 5, which is the point where aerodynamic heating caused by the speed of the vehicle cutting through the atmosphere becomes a factor.

The Air Force concluded its successful X-51 WaveRider program in 2013. The final test had the missile-like aircraft flying at Mach 5.1 for about 200 seconds.  Meanwhile, the Army is testing the advanced hypersonic weapon, a missile designed for vertical launch. It suffered a failed test seconds after takeoff in August 2014, but that was caused by a faulty booster, not the missile or hypersonic technology itself, Lewis noted….

Hypersonic technology could be seen as a follow-on to stealth, Lewis said. Even if an aircraft has that kind of technology, it doesn’t mean it is invisible, he said. Adversaries are growing better at spotting stealthy aircraft, he said. Speed might compensate for that, he said. “If I can fly really fast, it makes it harder to act against me. It doesn’t make it impossible. But it makes it harder.”

Top Air Force leaders are indicating that they want to move hypersonic technology to the next level.  Air Force Chief of Staff Gen. Mark Welsh and Secretary Deborah Lee James in the document “America’s Air Force: A Call to the Future,” said hypersonic development was number one on the service’s list of top five technology priorities.  [T]the Air Force sees hypersonic weapons as a potential means to break through anti-access/area-denied battlefields where adversaries have robust defenses….

The Air Force will team with the Defense Advanced Research Projects Agency on two new hypersonic programs, he said. The first will be a cruise missile called HAWC, the hypersonic air-breathing weapons concept. The other is called tactical boost glide, which will accelerate an aircraft to Mach 5 plus speeds, then let it glide to its target.

Similarly, space planes could deliver payloads in minutes. The reusable space plane concept has been proposed many times over the years, and received a new lease on life when DARPA awarded three contracts to Boeing, Masten Space Systems and Northrop Grumman to study the idea of a two-stage launch system that could rapidly place 3,000 to 5,000 pounds into orbit. The Air Force has never given up on that idea, as evidenced by the new DARPA initiative, Lewis said.  Space planes have been talked about for decades, Lewis said. There have been many starts and stops in developing the concept, he added.

NASA’s space shuttle was originally conceived as a vehicle that could rapidly lift payloads into space at low cost, and be flexible and responsive. It never lived up to that promise.

The DARPA experimental spaceplane (XS-1) program envisions a reusable aircraft that could be launched from a mobile platform, and return 10 times within 10 days. It would employ a reusable first stage that would fly to Mach 10 at a suborbital altitude. At that point, one or more expendable upper stages would separate and deploy a satellite into low-Earth orbit.  While a space plane in low-Earth orbit could potentially be used as a weapon, it would more likely be employed as a means to rapidly replace satellites that have been damaged in a space war, or to place sensors over regions where there are currently no assets, Lewis said….

Meanwhile, more akin to the space shuttle than the DARPA concept for the space plane, the Air Force continues to use the X-37B, a top-secret orbiter that also glides to Earth. One has been in orbit since October 2012. The Air Force has repeatedly denied that it has, or is intended to be, weaponized. What its exact mission is remains classified
