The Department of Transportation, specifically the Federal Aviation Administration (FAA), intends to award a single-source contract to dB Systems Inc. for the procurement of Commercial-Off-the-Shelf (COTS) Tactical Air Navigation (TACAN) Antenna Systems. The FAA requires approximately 38 TACAN Antenna 900E systems, along with installation support services, to replace aging legacy systems that are currently beyond their intended service life, posing significant operational risks. The 900E TACAN Antenna System is the only model approved for nationwide use and is critical for maintaining safety and operational efficiency in the National Airspace System.
