The Department of Defense, specifically the Department of the Navy, intends to negotiate a sole-source contract for the procurement of the Stinger Air-to-Air Launcher (ATAL) system from Raytheon Company. This procurement includes spares, training, sustainment, and associated engineering services to support the Marine Air Defense Integrated System Increment 1 (MADIS Inc. 1) program, as Raytheon is the original designer and producer of the ATAL, which is the only available solution that meets the program's requirements. The anticipated contract will be a hybrid Cost-Plus-Fixed Fee/Firm-Fixed-Price agreement with a performance period of five years, and interested parties must submit their interest and capability by 10:00 AM local time on April 17, 2025, to the primary contacts, Max L. G. Kirkman and Stasia Baker, via their respective emails.
