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

“The latest tests have shown that it has reached speeds close to 30 Machs. Practically at these speeds, no anti-missile can knock it down,” Borisov said.
In Wednesday's test, the weapon was reportedly launched from the Dombarovskiy missile base in the southern Ural Mountains. Moscow said it successfully hit a practice target on the Kura shooting range on Kamchatka, 6,000 kilometres (3,700 miles) away.
He noted that Russia has a stockpile of several dozen such missiles, which are in a factory-mint condition and not filled with fuel, allowing them to serve for a long time to come. Ivanov added that they could be put in existing silos, reducing the costs of Avangard's deployment.
"The Avangard has cost hundreds of times less than what the US has spent on its missile defence," Ivanov said, cited by Associated Press.
He noted that Russia began to develop the Avangard after 2002 when the US withdrew from the 1972 Anti-Ballistic Missile Treaty and began developing defences against ballistic missiles.
