The Black Sea Fleet is currently carrying out a set of measures to control the actions of the US Navy ships, the ministry said.
“Taking into account the fact that, in addition to the American Navy, it is planned to involve tactical, patrol and strategic aviation, as well as contingents of the armed forces of Bulgaria, Georgia, Romania, Turkey and Ukraine, there is a study of the alleged theater of military operations in the event that Kiev prepares a military solution in the south- east ", - quotes the message of the department RIA Novosti.
Such actions are a destabilizing factor in the Black Sea region, the Defense Ministry emphasized.
One of the goals of such activity was the military development of the territory of Ukraine.
According to the department, since October 30, the US Navy Porter destroyer with guided missile weapons has been in the Black Sea.
US Navy tanker John Lenthall entered there on November 3.
US Navy command ship Mount Whitney arrived on 4 November.
Also on November 6, two US Air Force strategic bombers flew over the Black Sea at a distance of 100 km from the Russian state border.
On October 21, Russian President Vladimir Putin announced a threat to Russia from NATO's military conquest of Ukraine.
He stressed that this "poses a threat to the Russian Federation, and we are aware of this."
