The Department of Homeland Security, specifically the U.S. Coast Guard (USCG), is seeking sources for the repair and overhaul of signal processors, receiver/transmitters, and antennas used on the HC-144 aircraft. This opportunity aims to identify commercially available vendors capable of providing these services in accordance with Original Equipment Manufacturer (OEM) specifications, as the HC-144 aircraft operates in challenging environments that accelerate wear and corrosion. Interested vendors must respond with detailed company information, product specifications, and relevant certifications by December 16, 2025, at 4:00 PM EST, and should direct their responses to Logan J. Brown via email at Logan.J.Brown3@uscg.mil.
