The Obama administration three years ago accused the Russians of violating the 1987 Intermediate-Range Nuclear Forces (INF) Treaty by developing and testing the cruise missile.
Michael Kofman, a Russian military analyst at the research organization CNA, indicated that the two units mentioned in the New York Times report are probably divisions similar to the structure of Iskander missile units.
The Obama administration expressed its concern over the test of the missile, then known as the SSC-X-8, in 2014. This must be what Trump was talking about on January 7 when he tweeted, "When I am President, Russia will respect us far more than they do now".
Secretary of Defense James Mattis is due to visit NATO's headquarters to meet with his counterparts Wednesday.
The head of the Russian upper house Committee for International Relations, Senator Konstantin Kosachev, said on Tuesday that such media leaks were part of a wider information war being waged against Russia and everyone who supported the normalization of Russia-US relations.
Moscow now seems to be testing the new president, however.
While Trump stumbles on policies from immigration to Russia, Flynn's chaotic management style left senior officials disjointed and frustrated, government officials told FP.
The missile deployment - and the lack of immediate response from the White House - showcases how the understaffed and embattled new administration is ill-prepared to face security threats, experts and officials say.
He said that "any non-compliance of Russian Federation with the INF Treaty would be a serious concern for the alliance".
The deployment has stirred concern in Congress, where Senate Armed Services Committee Chairman John McCain called it a "significant military threat to US forces in Europe and our North Atlantic Treaty Organisation allies". One is still at the nation's missile test site and the other has been shipped to an unnamed operational base.
Sen. Deb Fischer, chairman of the Subcommittee on Strategic Forces, say the missiles would be illegal under the Intermediate - Range Nuclear Forces Treaty. It also did not clarify when the cruise missiles were actually deployed.
