SRC supports the U.S. Army's Low, Slow, Small UAS Integrated Defeat System (LIDS) — the LIDS Counter-UAS Technology family of systems — with radar, electronic warfare, direction finding and camera systems to detect, track, identify and defeat Group 1 to 3 UAS. The AN/TPQ-50 radar provides multi-mission detection while the Counter-Small Unmanned Aircraft Electronic Warfare System (CUAEWS) contributes the EW defeat capability.

LIDS is part of SRC's broader Counter-UAS Technology portfolio, which has been fielded by the U.S. Army and Air Force since 2005 and used for VIP and event protection. In a landmark $1 billion foreign military sales agreement, SRC will deliver counter-UAS technologies to Qatar — the first international sale of the U.S. Army's Fixed Site–LIDS. A LIDS Family of Systems U.S. Army brochure is available.
