Russian President Vladimir Putin vows more combat test-firing of an experimental hypersonic missile fired at Ukraine on Thursday last, Press TV reported.
He said on Friday that the tests will depend on the situation and the character of any security threats Russia may face.
Putin said his country would also begin serial production of the new weapon.
The president said there would be more tests of the new Oreshnik missile, a day after Moscow fired the new missile at the Ukrainian city of Dnipro.
"We will continue these tests, including in combat conditions, depending on the situation and character of the security threats posed to Russia," Putin said in a televised meeting with military chiefs.
The new escalation follows Kiev’s use of American and British missiles capable of striking deeper into Russia.
In Kiev, parliament canceled its usual questions to the government on Friday over fears of a new Russian strike.
Ukraine said it’s seeking updated air defense systems from its allies in response to Moscow's new threats.
Meanwhile, Kiev’s forces are struggling on the ground. On Friday, Russia claimed the capture of another village in eastern Ukraine.
Putin lowered the nation's nuclear weapons threshold after the outgoing Biden administration removed the ban on Kiev to use Western-supplied long-range missiles against Russia.
On Tuesday, Putin signed a decree revising Russia’s nuclear doctrine to indicate the Kremlin's preparedness to respond aggressively to Ukrainian strikes inside Russia.
Months ago, western media reports said that the Americans, the British and the Germans had begun to provide Kiev with long-range missiles.
