On 18 December, the Romanian side gave the Navy the U.S. the object of the missile defence system that includes radar and a battery of interceptor missiles. The object should come into force in a few months.
This facility is the first of two such in Europe, the second is being built in Poland and should become operational in 2018.
In addition, deployed in Europe missile defence system includes a radar in Turkey and command post stationed in Germany and four in Spain the American ship protection systems against ballistic missiles.
The US says the missile defense system must protect cities of Europe and military bases from Iran and North Korea.
Against the deployment of missile defense in Europe was actively opposed by Russia, claiming that this system is directed primarily against it.
