DHS Has Limited Capabilities to Counter Illicit Unmanned Aircraft Systems

Executive Summary

DHS’ capability to counter illicit Unmanned Aircraft Systems (UAS) activity remains limited.  The Office of Strategy, Policy, and Plans did not execute a uniform department-wide approach, which prevented components authorized to conduct counter-UAS operations from expanding their capabilities.  This occurred because the Office of Policy did not obtain funding as directed by the Secretary to expand DHS’ counter-UAS capability.  We made four recommendations to improve the Department’s management and implementation of counter-UAS activities.  The Office of Strategy, Policy, and Plans concurred with all four of our recommendations.
