"In Rozas they carry out testing of military drones since March 2011 in complete darkness and opacity," Spanish lawmaker Ramon Vazquez Diaz said.
Diaz believes that these activities and major investments in airfield infrastructure demonstrate that NATO intends to convert the location into a key piece of its network in Western Europe.
"The heads of the [Spain's] Air Force… have admitted that Rozas airfield is ideal to establish a NATO drones base," the lawmaker added.
Diaz accused local authorities and the Spanish government of hiding plans from the public and not allowing lawmakers to inspect the facility.
Earlier in June, US and Spanish governments signed a controversial amendment to the Bilateral Agreement on Defense Cooperation that allows a permanent US Marine Corps presence at Spain’s Moron Air Base.
