The Department of Defense, through the Naval Sea Systems Command (NAVSEA), intends to award a federal contract for the production of Fire Control System (FCS) MK 99 equipment sets, primarily to Raytheon Missiles and Defense (RMD). This contract will consist of a base year and up to four option periods, supporting the DDG 51 Class Shipbuilding Program and Foreign Military Sales to allied Navies, along with necessary engineering and technical support. The FCS MK 99 is critical for naval operations, and RMD is the only qualified source capable of meeting the production and technical support requirements within the specified timeline. Interested parties may express their interest and capability within 15 days of this notice, but this is not a request for competitive proposals; all submissions will be at the submitter's expense.
