The foundational dataset for counter-UAS computer vision. CommonDefense delivers densely annotated imagery of UAS targets across every operational scenario — from Group 1 micro-drones against cluttered urban backgrounds to fixed-wing platforms at range against open sky.

80+ C-UAS-relevant object classes. Pixel-level instance segmentation. Oriented bounding boxes. Multi-spectral coverage across RGB, LWIR, and MWIR — because real-world counter-drone operations don't happen in a single spectrum.

Built for teams shipping counter-UAS systems, not publishing papers.
