"We are following and tracking all of this very closely, as are our brothers at the Department of Defense, and Americans should rest assured that we have a very good understanding of the Russian programs and how to make sure that Americans continue to be kept safe from threats from Vladimir Putin", Pompeo said.

The Kinzhal hypersonic missile was launched from an MiG-31 interceptor jet, which departed from an airfield in the Southern Military District, Russia's TASS News Agency reported. "The launch was successful, the hypersonic missile hit the designated target at the field", the statement added.
Russian Federation said today that it successfully launched a hypersonic missile capable carrying a nuclear warhead.
Putin said that Russian Federation also tested a new heavy intercontinental ballistic missile, called Sarmat, with a range and number of warheads exceeding its Soviet-era predecessor, known in the West as Satan.
Kinzhal air system crews have conducted hundreds of tests emulating attacks made from a position of defense.
Using colorful graphics and video, Putin said Russian Federation had also tested a nuclear-powered cruise missile and a high-speed underwater drone capable of carrying a nuclear warhead that, he claimed, would be impossible to intercept.
The first air unit equipped with the Kinzhal system started test air alert flights to master fundamentals of its combat use since December 1 of the past year.
Pentagon spokeswoman Dana White downplayed Putin's comments, saying the USA military was capable of defending the country from any threats.
On Sunday, U.S. Defense Secretary James Mattis expressed doubt that Russian Federation had developed such an advanced weapon and said the test would not affect U.S. policy, according to CNN.
"I saw no change to the Russian military capability and each of these systems that he's talking about that are still years away, I do not see them changing the military balance". "They did not impact any need on our side for a change in our deterrent posture".
The Russian leader said the high-speed underwater drone also has an "intercontinental" range and is capable of carrying a nuclear warhead that could target both aircraft carriers and coastal facilities.
During his speech, Putin said the creation of the new weapons has made NATO's US-led missile defense 'useless, ' and means an effective end to what he described as Western efforts to block Russia's military development.
