Russian President Vladimir Putin on Friday promised more combat test-firing of an experimental hypersonic missile launched at Ukraine, as Volodymyr Zelensky appealed for updated air-defense systems to meet the new threat.
Russia’s military threats reached new heights this week after the U.S. allowed Ukraine to use its ballistic missiles to hit Russian targets.
After striking the Ukrainian city of Dnipro with an experimental hypersonic missile early on Thursday, Putin ordered the mass production of the 'unstoppable' Oreshnik, believed to be able to reach Britain in under 20 minutes.
Russia has very few of these very expensive missiles and will not gut its nuclear deterrent by using a lot of them in Ukraine.
