Report Rollout: Mesh Sensing for Air and Missile Defense

On July 21, the CSIS Missile Defense Project rolled out our new report, Mesh Sensing for Air and Missile Defense. As threats to missile defense assets increase, the study assesses a vision for passive, proliferated sensor networks for surface-based air and missile defense. Using historical case studies and computer simulation-based analysis, the report identifies new considerations for sustainment, mission planning, network design, and mobility when deploying proliferated sensor meshes on Earth.

Protecting America’s Spectrum: A Fireside Chat with Senator Maria Cantwell (D-WA)

On June 12, 2025, the CSIS Missile Defense Project hosted a fireside chat with Senator Maria Cantwell (D-WA), Ranking Member of the Senate Committee on Commerce, Science and Transportation, on why protecting America's electromagnetic spectrum is critical to U.S. national security. The discussion examined spectrum challenges across defense, critical infrastructure, and emerging technologies that underpin our national security.

Why Auctioning Military S-Band Spectrum Is a Bad Idea

Auctioning the low-3 S-band spectrum for commercial 5G use poses serious national security risks, potentially interfering with military radar and missile defense systems. Given escalating air and missile threats, the U.S. should maintain exclusive military access to this spectrum while continuing to study long-term sharing options.
