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.
