The recent Chinese tests of suborbital hypersonic glide vehicles is a wake-up call to U.S. defense planners.

In July and August, China reportedly carried out tests of a hypersonic orbital missile capable of carrying a nuclear warhead. In recent days, there has been a flurry of press reports stating that these tests “shocked” the U.S. military and intelligence community, and were likely associated with an evolving Chinese weapon that is similar to the Soviet concept of Fractional Orbital Bombardment System (FOBS).

This could be a second “Sputnik moment” courtesy of the Chinese Communist Party (CCP) in less than three months, with the first being the disclosure that China began the construction of a potential intercontinental ballistic missile (ICBM) silo site in Hanginn Banner, Inner Mongolia, as a precursor to a breakout deployment of 300 new nuclear-tipped intercontinental ballistic missiles.

The Soviets’ launch of the first orbiting satellite in 1957 was subsequently termed a “Sputnik moment”—a rude awakening that sparked a furious response in a space race between the USSR and the United States.

With the two Chinese sub-orbital hypersonic missile tests, it could be argued that a hypersonic missile arms race is well underway.

The Hypersonic Missile Threat

There are two variations of hypersonic weapons that are being developed and/or deployed by the Russians, Chinese, and the Americans: glide vehicles and cruise missiles. Hypersonic glide vehicles (HGVs) can be launched from suborbital vehicles or boosted to high altitudes prior to launching by ballistic missiles—in the Chinese case, by their dual-use Long March rockets—and then use momentum and control surfaces to “glide” from high altitudes through the atmosphere before hitting their targets. The cruise missile versions launched by aircraft or from ships at sea use an advanced propulsion system for powered flight.

The potential use of hypersonic weapons in a conflict complicates the decision-making process associated with missile defense systems. Hypersonic missile speeds range from Mach 5 (about 3,700 mph) to Mach 15 (about 10,500 mph), with the latter referred to as “high-hypersonic.” The speed of these weapons adds a new calculus to the use of long-range missile defense systems, as the reaction times of anti-missile systems are greatly reduced, and intelligence, surveillance, and reconnaissance tracking (ISR&T) of the launch vehicles and the missiles in flight is a severe challenge. That time-difference calculation further complicates the ISR&T process when a hypersonic glide vehicle is launched from an orbiting vehicle (an operational FOBS), as the payload could be launched from orbit at virtually any target on Earth without warning.

If deployed in large numbers, a first-launch strike could inflict near-instantaneous effects on a large number of primary and secondary targets at the beginning of a conflict—decapitating a country’s leadership, military command, control facilities, and ground-based satellite communications systems.

The speed at which these targets would be hit could greatly change the escalation decision-making thought process; for example, determining whether how and when to respond to such an attack. Reaction times are greatly decreased and the ability to detect pre-launch actions is complicated, as the weapons do not require easily detected launch preparations—which complicates the tactical decision-making thought process of commanders in the field.

Decreased reaction times would drive defensive missile systems toward automated response through the incorporation of artificial intelligence capabilities. Think of an early version of “Skynet” of “The Terminator” movie series that is focused on automated ISR&T and missile defense.

The Hypersonic Missile Arms Race

A hypersonic missile arms race has been underway for a while now, for all practical purposes.

The Chinese People’s Liberation Army (PLA) were the first to deploy an operational hypersonic missile system. The DF-17 Dongfeng medium-range ballistic missile system entered service in September 2019, just in time to be paraded in Tiananmen Square to mark the 70th anniversary of CCP rule. The Chinese have also tested the DF-41 intercontinental ballistic missile, which could carry a conventional or nuclear HGV, and is capable of hitting the continental United States.

The Russians also deployed an operational hypersonic missile capability in late 2019. The first regiment of their new Avengard missiles entered service on Dec. 27, 2019, with each missile capable of delivering a 2-megaton nuclear payload. Russia is also developing the Tsirkon, which is a ship-launched hypersonic cruise missile that is capable of traveling between Mach 6 and Mach 8.

The United States has been racing to catch up. A successful test was conducted in March 2020 of a joint common hypersonic glide body (C-HGB) that rode a modified Polaris A3 booster from a launch pad at the Pacific Missile Range Facility in Kauai, Hawaii, according to USNI News. The U.S. Army has already commenced equipping its first hypersonic missile-capable unit, I Corps’ 5th Battalion, 3rd Field Artillery Regiment, and 17th Field Artillery Brigade. But the first long-range hypersonic weapons dubbed the “Dark Eagle” won’t be delivered until 2023, according to Defense News. And both the U.S. Navy and U.S. Army have tested hypersonic missile components on Oct. 20. The U.S. Air Force, Missile Defense Agency, and DARPA are also investing in hypersonic missile and hypersonic missile defense programs, but none of these systems will be deployed before 2023 at the earliest.

Hypersonic missiles are not covered under the New START Treaty, a five-year extension of the expiring nuclear arms treaty that was agreed to by Russia and the United States in February 2021. And China is not a signatory to any nuclear weapons treaty. In fact, the New START Treaty limits the United States to “1,550 nuclear warheads on deployed ICBMs, deployed SLBMs, and deployed heavy bombers equipped for nuclear armaments,” while the Chinese are unconstrained by any nuclear weapons limitations and continue to resist bilateral nuclear arms talks with the United States.

First Strike or Deterrence?

Given the CCP’s propensity for psychological warfare in support of its strategy to “win without fighting,” one could argue that these new missile tests are more for intimidation of potential adversaries than for actual use—a sort of deterrent that reinforces a country’s diplomatic actions or implements “mutual vulnerability.” However, their use in a “surprise attack” is certainly within the realm of possibility and cannot be ignored. At the very least, deployment of a Chinese operational HGV/FOBS system complicates homeland defense of the United States and other nations in ways unforeseen.

A first-strike or deterrence FOBS that deploys hypersonic glide vehicles has massive technical challenges that need to be overcome before becoming fully operational. Some of these include, but are not limited, to the following:

  • The energy requirements needed to accelerate a missile with a large payload from Mach 5 to Mach 10 in the low atmosphere.
  • HGV launches should be detectable in both the visual and infrared spectrums, while providing a unique launch signature.
  • The dynamic pressure on the airframe produced at Mach 5+ speeds create chemical corrosion problems in flight that must be overcome (potentially through some combination of thermal and chemical protection).
  • Post-launch navigation and maneuverability is non-trivial. Maneuverability during flight is a key main engineering problem that must be overcome to ensure their effectiveness against point targets.

Has the PLA-Rocket Force (PLARF) solved all of its engineering problems, as well as developed the command and control and ISR&T system needed to coordinate and direct HGV launches from orbit? That is what tests are for, and the world will need to watch and analyze future PLARF tests of what could become a HGV/FOBS capability very carefully. Needless to say, the Cold War-era “nuclear triad”—submarines, aircraft, land-based ICBMs—is on the verge of becoming a “nuclear quadrangle.”
