16--INERTIAL NAVIGATION, IN REPAIR/MODIFICATION OF

The Navy is seeking a single source provider to supply, repair, or modify 55 units of a flight‑critical inertial navigation system (NSN 7R‑1680‑015708454‑QE). The parts are not stocked publicly; the Government requires prior source approval, and only previously approved vendors may submit proposals. Bidders must include detailed technical data, source‑approval documentation, and any prior approval cover letters. The solicitation is issued under FAR 6.302‑1, emphasizing the urgency of acquiring the parts without a competitive process. • Quantity: 55 units, FOB origin delivery. • Must provide source‑approval data per NAVSUP WSS brochures; new source approvals unlikely to be processed in time. • Proposals accepted for 45 days (or 30 days if using an existing BOA) after posting; the deadline is 14 Dec 2026. • All communications and submissions must follow the specified NAVSUP instructions and include required technical documentation.
