A top Russian official said the nation’s new strategic weapon has made any missile defenses useless.

Deputy Prime Minister Yuri Borisov told Russian state television Thursday, Dec. 27, that the Avangard hypersonic glide vehicle flies 27 times faster than the speed of sound, making it impossible to intercept. He added that the new weapon “essentially makes missile defenses useless.”

Borisov spoke a day after Russian President Vladimir Putin oversaw the Avangard’s reportedly successful test and hailed it as a reliable guarantee of Russia’s security for decades to come.

In Wednesday’s test, the weapon was launched from the Dombarovskiy missile base in the southern Ural Mountains. The Kremlin said it successfully hit a practice target on the Kura shooting range on Kamchatka, 3,700 miles away.

The test comes amid bitter tensions in Russia-U.S. relations.
