Mesh Sensing for Air and Missile Defense
Affordable mass has become the watchword of defense modernization, be it swarms of drones or satellite constellations. What could such an approach mean for air and missile defense? Networks of passive, proliferated sensors could make one meaningful contribution.
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.

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.
