Russia is maintaining giant bunkers underneath Moscow where Kremlin bigwigs can live underground for months after a nuclear attack, because the administration is convinced the U.S. plans on overthrowing President Vladimir Putin, according to a newly revealed Pentagon report.

“A deep underground facility at the Kremlin and an enormous underground leadership bunker adjacent to Moscow State University are intended for the national command authority in wartime,” says the report, according to the Times of London.

“Highly effective life-support systems may permit independent operations for many months following a nuclear attack.”

The Defense Intelligence Agency report on Moscow’s military might — the first since the Cold War — says the “enormous” bunkers are 985 feet underground and can house as many as 10,000 people in the case of nuclear Armageddon, according to the paper.

The shelters are linked to other bunkers outside of the city — as well as the VIP terminal at Vnukovo airfield, in case the honchos need to flee, the report said.

The report, which predates President Trump’s election but was released Wednesday, says Putin believes the U.S. is intent on regime change as part of our “efforts to promote democracy around the world.”

“The Kremlin is convinced the United States is laying the groundwork for regime-change in Russia,” the report says.
