Autonomous Weapons


Information technology is driving rapid increases in the autonomous capabilities of unmanned systems, from self-driving cars to factory robots, and increasingly autonomous unmanned systems will play a significant role in future conflicts as well. The prospect of increased autonomy in weapons systems raises challenging legal, moral, ethical, policy and strategic stability issues. Nation-states and activists in the United States and abroad are already debating how advances in autonomy will influence warfare – and what, if anything, should be done. Activists have launched a “Campaign to Stop Killer Robots,” comprised of over 60 non-governmental organizations. For the past several years, state parties to the United Nations’ Convention on Certain Conventional Weapons have held informal discussions on autonomous weapons, and states agreed in 2016 to form a Group of Governmental Experts to further explore the issue. 

Governments and militaries are only beginning to grapple with how to address the challenges and opportunities associated with increased autonomy. Technology is moving fast in this area. Few states have guidelines on how autonomy should be included in future weapons systems, with the United States a notable exception.

CNAS’ Ethical Autonomy project examines the legal, moral, ethical, policy and strategic stability dimensions of increased autonomy in future weapon systems. The goal of this project is to help states, activists, academics and militaries grapple with the challenging issues of autonomy in future weapons. This dialogue is necessary to ensure an appropriate balance between ethical and strategic stability considerations, technological opportunities and future warfighting needs.

CNAS Senior Fellow Paul Scharre asked experts to examine the future of autonomous weapon systems. View their responses.
