“The final tests involving the Sarmat intercontinental ballistic missile have been a success,” he said, according to the Kremlin’s official translation.
The Sarmat – known in the West as Satan-2 – is seen as Russia’s most powerful nuclear-capable intercontinental ballistic missile.
Initial Russian news reports of Putin’s words at a promotion and awards ceremony for senior officers translated him as saying final tests of the missile were “proceeding successfully”.
This is reflected by Putin’s words on video.
But the Kremlin’s own translation strengthened his claim to say the final tests “have been a success”.
The “invincible” hypersonic weapon was shown earlier on video emerging from an underground silo at Plesetsk spaceport – pausing as if hovering above the ground and then speeding to its target in a cloud of white smoke.
Moscow says Satan-2 can evade the United States’ defence shield and is capable of destroying an area the size of England and Wales — or Texas.
Russia is planning for the RS-28 to enter service by the start of the next decade as a part of its ongoing push to modernize its nuclear arsenal.
Putin was quoted as saying: “Large-scale and consistent the work has been in recent years to develop the army and the navy in a comprehensive manner and to saturate line units with advanced military equipment.
“For example, the Avangard missile system with a boost glide vehicle – our hypersonic intercontinental system – will considerably enhance the power of the Strategic Missile Forces….
“As you may know, the Kinzhal hypersonic system and the Peresvet laser system have been put on alert duty.”
He boasted: “The Navy’s new surface ships and nuclear submarines will be armed with advanced types of weapons, including the Zircon hypersonic missile, which has no parallels in the world in terms of range and speed.”
Russia is known to be poised to carry out tests on the 6,000 mph Zircon – or Tsirkon – with the Mach 8 missile identified recently by Moscow’s state-controlled TV as being President Putin’s weapon of choice to wipe out American cities in the event of nuclear war.
Mr Putin said: “It is these modern powerful precision weapons that are determining and will determine in the future the image of Russia’s Armed Forces.
“For this reason, the requirements to personnel training and the quality and intensity of combat drills are becoming even stricter.
“What we need is a real fusion of Russian martial traditions and the most up-to-date, advanced knowledge, technology and skills in using these to a good effect.”
The hypersonic Kinzhal travels at ten times the speed of sound and has been tested in southern Russia.
It is launched from a high-altitude MiG-31 fighter jet and can be fitted with nuclear or conventional weapons.
It has an effective range of 1,250 miles.
Some 350 training missions are known to have been conducted by the military unit tasked with testing the Kinzhal.
The Peresvet “combat laser system” has a cannon-like device which is believed to be a highly sophisticated jamming weapon.
The aim is to ‘blind’ the optical electronic equipment of enemy vehicles with a laser beam, it is claimed.
The Avangard – Russia’s hypersonic intercontinental missile system – is said to be capable to withstand high temperatures near a potential target.
It will “seriously boost” the capability of Russian military rocket forces, said Mr Putin.
After earlier Mr Putin boasts about the Sarmat, Western experts expressed scepticism on how close Moscow was to operational use.
But US officials have sounded a growing alarm about the potential threat from hypersonic weapons – those that can travel at five times the speed of sound or more.
Russia says the new missile can carry a payload of up to 15 warheads and it was planned to enter service at the start of the next decade to modernise Moscow’s nuclear arsenal.
