US LIDS (Low, Slow, Small UAS Integrated Defeat System)

The US LIDS (Low, Slow, Small UAS Integrated Defeat System) is a family of systems designed to detect, track, identify, and defeat Groups 1-3 unmanned aircraft systems (UAS) using passive and active sensors, electronic warfare, kinetic effectors like the Coyote Block 2 interceptor and XM914 30mm chain gun, and integration with FAAD C2 for command and control. It includes fixed-site (FS-LIDS) and mobile (M-LIDS) variants mounted on platforms like M-ATVs, with M-LIDS designated as an Army program of record (ACAT III) in March 2022 and ongoing contracts for production, deployment, and support as of January 2023. The system is operational and in procurement, providing critical counter-UAS defense for fixed sites, mobile forces, and training environments, with strategic significance in addressing proliferating small drone threats through multi-mission radar, kinetic/non-kinetic defeat, and interoperability.
