The Department of Defense, specifically the U.S. Army Contracting Command at Aberdeen Proving Ground, is conducting a Sources Sought notice to identify potential sources for radio systems, communications equipment, and associated services to support Foreign Military Sales (FMS). The procurement aims to fulfill requirements for various radio systems, including the FALCON series and Tactical SATCOM Terminals, which must be compatible with existing L3Harris products and meet specific operational and environmental standards. These systems are critical for enabling communication among allied forces in operational missions, ensuring interoperability and efficiency. Interested parties should submit their capabilities and relevant information to Contract Specialist Michael F. Siwek by email no later than 1:00 p.m. EDT on August 25, 2025, as this is not a solicitation for proposals but a market research initiative.
