The Department of State (DOS) is seeking qualified vendors to provide Less Than Lethal (LTL) Technical Security Systems (TSS) for use in securing U.S. diplomatic compounds. The procurement aims to identify companies with expertise in LTL compound defense systems, specifically those offering commercial off-the-shelf (COTS) or modified COTS solutions that enhance crowd control and deterrence capabilities. These systems must comply with U.S. manufacturing laws, operate continuously in deterrent mode, and exclude cloud-based, Wi-Fi, and Bluetooth technologies, ensuring low visual impact and safe operation under extreme environmental conditions. Interested parties should respond to the sources sought notice by contacting Adam Hiland at HilandAD@state.gov or Antwaun Cherry at CherryAF@state.gov, providing detailed information on their systems, including technical specifications and cost estimates, with no specific funding amount or deadline mentioned in the overview.
