Conventional Prompt Global Strike: A Fresh Perspective

Conventional prompt global strike (CPGS) is the proposed capability to deliver a precision nonnuclear weapon against a target anywhere in the world in less than an hour. Despite years of study and debate, the need for a better understanding of the issues related to this capability remains. Recent political, arms control, and fiscal developments warrant a fresh look at conventional prompt global strike. Analyzed here are potential contributions of CPGS to U.S. national security objectives, weapon-system options for the CPGS role, arms control limits that apply to certain options, and some possible drawbacks of CPGS capabilities. Overall, a number of CPGS options could enhance U.S. and allied security within the existing arms control framework and without creating significant risks.
