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.
