Speed Kills: Analyzing the Deployment of Conventional Ballistic Missiles

Summary

Should the United States deploy conventional ballistic missiles (CBMs) in support of the prompt global strike (PGS) mission? Most important, do the political-military benefits outweigh the risks of CBM deployment? The United States, if it works to mitigate the risk of misperception and an inadvertent nuclear response, should deploy near-term CBMs in support of the PGS mission. The prompt response of CBMs would likely be sufficient to defeat many time-sensitive, soft targets, provided actionable intelligence was available. Near-term CBMs, those options capable of being deployed prior to 2013, would have the required attributes to defeat their targets: payload flexibility, throw weight, and accuracy. More specifically, the U.S. Navy's Conventional Trident Modification is a cost-effective, near-term PGS option that would mitigate the concerns of CBM opponents. The large-scale use of midterm and long-term CBMs against mobile targets and hard and deeply buried targets, however, will require a wider range of technologies that have yet to mature. Thus, the United States should continue investing in research and development for a broad portfolio of PGS options to cover the emerging target set.
