The Department of Homeland Security, specifically the U.S. Coast Guard, is seeking information regarding the procurement and sustainment of a new Environmental Control System (ECS) to replace the existing vapor cycle refrigeration system in the H-65 helicopter. The Coast Guard aims to identify ECS solutions that are lighter in weight and provide greater cooling capacity, with a focus on future avionics upgrades and compliance with specific design and integration requirements. The H-65 helicopter is crucial for short-range search and rescue operations, and the new ECS will enhance its operational capabilities. Interested suppliers must submit their responses by October 16, 2024, to Alyson Harrison at alyson.s.harrison2@uscg.mil, and include their company information and capability statements as outlined in the RFI numbered 70Z03825IB0000001.
