The Express reports: The menacing-looking aircraft will also be able to drop nuclear warheads from space, according to Vladimir Putin’s TOP boffins.
Another detail likely to worry Western armies is the plane’s ability to travel at up to five times the speed of sound.
A spokesman from Kremlin-backed Fund for Perspective Research said: “Materials must withstand temperatures of 1,500C and more for a prolonged period of time.
“Conventional materials, such as high-strength steel, melt at these temperatures.
“There has been considerable progress in this sphere.”
Russian air force chiefs aim to have the cutting-edge weapon operational by 2020.
Tensions between between Russian and the West are at an all time high.
But the announcement by the research fund comes as the fear of war between Mr Putin and Western governments remains at a sky-high level.
British Navy vessels yesterday shadowed a Russian warship as it passed through the English channel on its way to the Mediterranean.
And a further warning was issued by award-winning defence author Arkady Ostrovsky that Mr Putin may push the world to the brink of nuclear war.
Successive wars in Georgia, Ukraine and Syria have demonstrated Russia's willingness and ability to use its military power to achieve political goals, Mr Ostrovsky argued.
But Mr Putin's belligerent approach is not a sign of Russia's unbridled strength, he added.
Instead, it reveals deep insecurity and weakness in the Kremlin, Mr Ostrovsky said.
