In 2018, Russian President Vladimir Putin announced five new nuclear-capable, strategic weapons systems. These systems include a nuclear-powered, nuclear-armed cruise missile and a nuclear-powered, nuclear-armed submarine drone. What does Russia have to gain from developing these novel and exotic nuclear weapons? And what should the United States and NATO do about it?

This new Atlantic Council issue brief, Russia’s Exotic Nuclear Weapons and Implications for the United States and NATO, answers these questions. Informed by a workshop convened by the Scowcroft Center for Strategy and Security and Los Alamos National Laboratory, authors Matthew Kroenig, Mark Massa, and Christian Trotti evaluate the potential utility, motivations, and consequences of these new systems. Among other conclusions, the most significant may be that great-power competition has returned, and with it, the importance of nuclear weapons in international politics.
