The Department of Defense, through the Defense Logistics Agency (DLA) Aviation at Philadelphia, PA, is soliciting proposals for the procurement of radar transmitters, specifically identified under the NAICS code 334511. The contract requires suppliers to provide FAA-certified parts with an FAA Authorized Release Certificate, as these items are classified as Critical Safety Items (CSI) and must meet stringent quality and inspection standards. This procurement is vital for maintaining the operational readiness of defense systems, and all offers must be for newly manufactured spares, as refurbished or remanufactured items will not be accepted. Interested vendors should submit their proposals electronically to Samuel Everett at SAMUEL.EVERETT@DLA.MIL by the extended deadline of November 7, 2025.
