Russia has begun serial production of new Zircon hypersonic missiles, which experts say are almost impossible to shoot down, President Vladimir Putin said Friday. 
Use of missile in war: Ukraine has claimed it has evidence that Russia fired a Zircon hypersonic missile in its attacks on the capital Kyiv on February 7 for the first time since the start of the war.
Experts say the Zircon, if it lives up to what Moscow says about it, is a formidable weapon. Its hypersonic speed makes it invulnerable to even the best Western missile defenses, like the Patriot, according to the United States-based Missile Defense Advocacy Alliance (MDAA).
What else Putin said: Russian defense industry enterprises have "in recent years" increased the production and supply of weapons "multiple times over," including high-precision strike weapons and unmanned aerial vehicles, tanks, armored vehicles, artillery, air defense systems, counter-battery systems, and communications and reconnaissance equipment, he said in a Defender of the Fatherland Day address, which Russia marks on February 23.
Other technologies, including the introduction of artificial intelligence in the military sector, are also being developed, the Russian leader said.
He praised the "courage and valor" of members of the military, including those who serve in what Russia calls euphemistically its "special military operation" in Ukraine.
 "You are true national heroes," Putin said. "We know it is difficult for you, and we will do everything possible to help you complete the mission you have been assigned," he added.
