"They stole during the Barack Obama administration. They stole classified drawings and built it," the former US president claimed.
'Russia Has Its Own Excellent Missile'
"It’s hard for me to say whether it fits in well with Mr. Trump's term ‘super-duper,’ but it is a good missile that has no rivals in the world for now. And there is not just one [such missile]," Peskov pointed out.
US Lagging in Hypersonic Weapons Development
"Trump says that the drawings were stolen. But wait, someone made those drawings, so where is this person or group of comrades?" the expert said, in an apparent nod to American designers.
"Anyway, where are these American hypersonic projects? This is all about technologies rather than the drawings. For us, all this happened consistently, and we were already on the verge of a breakthrough [into hypersonic development] before the collapse of the Soviet Union [in 1991]," Leonkov underscored.
"Now we are already working on the second generation, so there was no point in stealing certain US drawings. On the contrary, it were Americans who tried to steal our hypersonic research and development. Russian special services have recently tackled several [US] espionage attempts in this field," Leonkov said.
"We improved technologies as we carried out complex physical and mathematical modeling, resolving the issue of reliable communications and control at hypersonic speeds," he added.
'Super Duper' Bluff
"When it comes to development of hypersonic weapons, Russia outdid America by at least a decade. That’s why it’s safe to assume that it was the US which could steal our drawings. Judging by the fact, however, that America is yet to make progress in creating hypersonic weaponry, our drawing are in place," Mikhailov concluded.
