Militaries around the world are incorporating AI and autonomy into their organizational processes, command and control systems, logistics systems, and, of course, weapon systems themselves—with an aim toward leveraging current develop- ments from the commercial world. As AI and autonomy proliferate on the battlefield, an important question arises: How might deterrence be affected by the proliferation of AI and autonomous systems? Up to this point, deterrence has primarily involved humans attempting to affect the decision calculus and perceptions of other humans. But what hap- pens when decisionmaking processes are no longer fully under the con- trol of humans? In this report, we lay out some initial considerations and present ideas for how deterrence could change in the age of AI and autonomy.

The increased use of unmanned sys- tems on the battlefield, breakthroughs in commercial AI, and interest that many countries now have in AI and autonomous systems for mili- tary applications make it likely that such systems will be widely used in future conflicts. Yet what happens to deterrence and escalation when decisions can be made at machine speeds and when states can
