Romania has been a member of the North Atlantic Treaty Organization since 2004. As a relative newcomer the country was quick to participate actively in allied operations.
On September 13, 2011, the US and Romania signed an agreement that would allow the US to construct, maintain and operate a land based SM-3 Ballistic Missile Defense (BMD) system in Romania. As part of the second phase of the European Phased Adaptive Approach, the deployment of the site is set for 2015.
The US and Romania jointly selected the Deveselu Air Base near Caracal, Romania to host the US Ballistic Missile Defense System, which will be composed of SM-3 interceptors, also referred to as Aegis Ashore.
Like the US agreements between Turkey and Poland, Russia has expressed its concerns over the proposed interceptor system in Romania.
Romania will host the SM-3 interceptors starting in 2015.
