In February 2010, the Supreme Council of National Defense signed an agreement with the United States for missile defence under whose terms land-based SM-3 systems would be installed in Romania. On 3 May 2011, the president of Romania Traian Băsescu announced the location for the SM-3 systems: former Air Force base Deveselu in Olt County. The system includes 3 batteries with 24 SM-3 Block I rockets, manned by approximately 200 US soldiers (with a maximum of 500) under Romanian Air Force overall command. The Deveselu Aegis Ashore site has been declared operational on the 13th of May 2016.
