The Commission of the Bishops’ Conferences of the EU (COMECE) has published a new reflection paper calling upon states to take action on armed drones. The publication, titled “Technology at the Service of Peace“, examines the development, use, and export of armed drones as well as the development of fully autonomous weapons, also known as killerrobots. EFAD members were also consulted for the this report. Based on this reflection, COMECE provides several recommendations to the EU and its Member States on how to address the challenges posed by such ‘uncrewed’ armed systems.
