The Kremlin have vehemently denied the claims that all four tests of Putin’s super missiles between November and February ended in crashes.
The Russian President announced the “invincible” machines during a speech in March.
Putin said: “Since its range is unlimited, it can manoeuvre as long as you want.
“For now, no one in the world has anything like this.”

However, according to American data, the furthest any of the missiles travelled was 22 miles, and crashed after just two minutes.
The shortest flight lasted just four seconds, and crashed after cruising for five miles.
One of Putin’s team has been quick to slam the US announcement.
Dmitry Peskov told media on Tuesday: “Listen to the President of Russia Vladimir Putin and believe him.”
The Kremlin initially ordered the tests after engineers insisted the systems were not ready.
After using conventional fuel to get off the ground, the missile is powered by a small nuclear reactor throughout the rest of the flight.
The US intelligence sources say the nuclear component of the missiles failed to start, causing the crashes.

However, Putin insisted the nuclear unit has “provided the necessary level of thrust” for the weapons to fly.
The new missiles were intended to overcome US defence systems based in eastern European countries such as Poland and Romania.
The American presence in other countries “violates the strategic balance” between the nuclear powers, according to the Russian leader.
He said: “No one wanted to listen to us.
“Listen to us now.”
