The Department of Defense, through the Naval Sea Systems Command (NAVSEA), is conducting market research for the Inertial Navigation System (INS) Design Agent and Engineering Support (DA/ES) for the next generation INS, designated the AN/WSN-12. This opportunity aims to identify potential sources capable of modernizing and producing the INS, which is critical for precise navigation in naval vessels, particularly in environments where GPS data is unreliable. The selected contractor will be responsible for engineering support, system design, and manufacturing, with project activities anticipated to commence in Fiscal Year 2026 and continue through FY 2031, requiring the delivery of the first INS shipset by the fourth quarter of 2026. Interested parties must submit their responses to the Request for Information (RFI) by email to the designated contacts, Janel Duval and Tiffany Wulfsohn, within 30 days of the notice publication, ensuring compliance with security requirements and submission guidelines.
