[8] In February 2010, the Supreme Council of National Defence decided for Romania to participate in the development of the American anti-missile defense component, at the invitation of President Barack Obama.

[9] According to major general Charles Miller, "Aegis Ashore Romania is designed to protect European NATO Allies and U.S. deployed forces in the region against the growing threat posed by the proliferation of ballistic missiles outside the Euro-Atlantic area.

"[10] The defense system is under the operational control of United States Naval Forces Europe-Africa, based in Naples, Italy.

During the modernization works, the United States military temporarily installed Terminal High Altitude Area Defense (THAAD) systems at the base.

[14] The $800 million facility was originally intended to intercept incoming missiles from Iran, but has been deemed a "direct threat" by Russian officials.

The Aegis Ashore missile defense system at Deveselu (and another one in Redzikowo, Poland), has been brought up by Russian President Vladimir Putin as an example of NATO's increasing influence in Eastern Europe.

[3] In the wake of the 2022 Russian invasion of Ukraine, the Aegis Ashore Missile Defense Complex in Deveselu has assumed an essential role for the security of the NATO Alliance; the SM-3 interceptors have the capability to destroy slower, medium-range ballistic missiles with potential nuclear payload during mid-course flight, but probably wouldn't work against hypersonic weapons according to Kingston Reif, Director for Disarmament and Threat Reduction Policy.

Investments will be made starting in 2024 and aimed at upgrading the detection sensors and facilities as well as replacing the missiles with newer ones, increasing the capability of intercepting more types of weapons.

[22] It was reported in 2016 that over 20 American B61 nuclear bombs were moved from the Incirlik Air Base in Turkey to Deveselu after the failed Turkish coup.
