The high-tech gliders will be capable of penetrating “virtually every” missile defence system, according to a top figure at a Russian military research agency.
Boris Statovsky, of the Future Research Fund in Moscow, said the breakthrough would ensure “global military-strategic parity” within four decades.
He said: “Thanks to their outstanding technical characteristics, such systems will be able to break through virtually every existing missile defence system, thus ensuring global military-strategic parity in the next 30 to 40 years.”
Mr Statovsky added that in combat the warheads are almost impossible to intercept thanks to their ability to shift targets in flight.
Russia has twice tested the breakthrough technology this year as part of a drive to replace traditional missiles.
Kremlin aide Yuri Ushakov said the Russian leader discussed “different themes” with Obama before touching on the subject.
He said: “There was a tete-a-tete conversation and different themes were discussed.
“The theme was touched upon. A really clear reply was given by our side which perhaps id not fit with what Obama was trying to explain to us.”
The Future Research Fund has sponsored scientific research for the Russian military since 2012, including high-risk projects with the potential of reaching major breakthroughs for Vladimir Putin’s army.
The Fund is developing 50 new hypersonic ballistic glider projects in more than 40 laboratories at Russian universities, research institutes and defence enterprises.
