Hypersonic Weapons

A new arms race is afoot. China, Russia, and the United States are aggressively pursuing the development and deployment of advanced hypersonic weapons, while other states are starting or scaling up their own programs. But what are these weapons? Who’s working on what? And what are the implications for global security? A strategy for managing the race toward these weapons—which combine speed with maneuverability and long ranges—has never been more crucial.
