Does Russia Really Have Hypersonic Weapons That Are 'Operational'?

Sometimes being first isn't always best. 

The Russian defense ministry claimed it has deployed the Avangard surface-to-surface hypersonic missile, possibly making Russia one of the first countries to field an operational guided missile capable of traveling faster than five times the speed of sound.

 

Defense Minister Sergei Shoigu informed Pres. Vladimir Putin that the first Avangard unit was ready for combat, the Kremlin announced on Dec. 27, 2019.

TASS news agency, which is controlled by the government, called the deployment a "remarkable event.”

“No existing defenses, in the United States or elsewhere, can intercept a missile that can move so fast while maneuvering unpredictably,” Steven Simon, an analyst for the Washington, D.C. Quincy Institute, wrote in The New York Times.

But foreign military planners probably shouldn't panic. The Kremlin might be exaggerating the effectiveness and usefulness of its new weapon.

Avangard is what the U.S. military calls a “hypersonic glide vehicle.” Propelled to high speed by the same kind of rocket that boosts a satellite or an intercontinental-range nuclear warhead, a hypersonic glide vehicle follows a different kind of flight path than other payloads do.

Staying relatively close to Earth — around 300,000 feet up, approximately where the atmosphere ends and space begins — a hypersonic vehicle glides toward its target at many times the speed of sound, potentially performing small maneuvers while en route.

In theory a hypersonic glide vehicle can carry a conventional explosive warhead, a nuclear warhead or no warhead at all, instead relying on sheer kinetic force to destroy its target. Its low altitude and high maneuverability compared to a traditional intercontinental ballistic missile could make it harder to intercept.

"We don't have any defense that could deny the employment of such a weapon against us," Gen. John Hyten, commander of U.S. Strategic Command, told the Senate Armed Services Committee in March 2018.

But ICBMs already are capable of blasting through normal defenses. The United States and Russia both possess missile-interceptors they claim can hit incoming ICBMs, but experts question the interceptors’ effectiveness against such fast targets.

The U.S. Army's Ground-Based Midcourse Defense missiles in Alaska and California represent America's main defense against nuclear-armed ballistic missiles. But the GMD rockets lack the speed, maneuverability and accuracy to hit an ICBM, which in its final phase of flight can reach a velocity 20 times the speed of sound.

The U.S. Missile Defense Agency claimed the GMD system intercepted a "complex, threat-representative ICBM target" during a May 2017 test. But experts claimed the test was unrealistic. "The Missile Defense Agency simplified the test to enhance its chances of succeeding," said Laura Grego, a missile expert with the Union of Concerned Scientists in  Massachusetts.

If American defenses can't hit an ICBM, they probably also would fail to hit a Russian hypersonic glide vehicle. But that might not matter, if Moscow intends to deploy Avangard or another hypersonic vehicle as a strategic weapon carrying a nuclear warhead.

No country has ever possessed a reliable defense against a long-range strategic weapon. Instead, nuclear states count on the threat of atomic counterattack -- "mutual assured destruction" is the Cold War term -- in order to deter a nuclear attack.

Avangard could become just another strategic weapon that that United States counters with strategic weapons of its own. "Our response would be our deterrent force, which would be the triad and the nuclear capabilities that we have to respond to such a threat," Hyten said.

Hypersonic weapons might be more useful, and more effective, if they do not carry nuclear warheads. In July 2018, Michael Griffin, the U.S. Defense Department's undersecretary of defense for research and engineering, warned about the "tactical capability that these sorts of weapons bring to theater conflicts or regional conflicts."

Griffin characterized hypersonic vehicles as "very quick response, high speed, highly maneuverable, difficult to find and track and kill."

With Avangard reportedly combat-ready, Russia competes with China to be the first country to deploy a hypersonic weapon. China in October 2019 publicly debuted its DF-17 hypersonic surface-to-surface missile during a military parade in Beijing.

It’s unclear whether the DF-17 actually is operational. It’s also unclear how many DF-17s China possesses and how it plans to use the missiles during wartime. Most importantly, it’s not obvious that China has built a sensor network capable of selecting targets for the DF-17.

David Larter in a November 2019 column in Defense News cautioned against assuming the DF-17 and other hypersonic missiles are transformative. “The catch is that none of this stuff works yet,” Larter wrote. “I want to emphasize that all of what we’re talking about here are prototypes.”

The United States is developing its own hypersonic missiles and aims to deploy them in the early 2020s.

In rushing to be first, Russia and China could end up fielding unreliable hypersonic weapons. In July 2018, Griffin asserted that the United States remained the world leader in hypersonic-weapons research. The Pentagon determined there was no need to hurry up and equip troops with an unrefined weapon.  "We didn’t see a need for it."

America's hypersonic weapons would mature "through the 2020s," Griffin said. “You’re going to see our testing pace stepping up, and you’re going to see capability delivery from the early '20s right through the decade."
