But are they truly operational?
Key point: The United States is developing its own hypersonic missiles and aims to deploy them in the early 2020s.
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.
