This opportunity is for the acquisition of 11 units of a part (NSN 0Q-5940-017216317-V2) with an unstable design, as major changes are anticipated that will render the current configuration obsolete. Delivery is FOB Origin, and the item requires Government source approval prior to award due to its flight-critical nature. Only previously approved sources have been solicited, and new sources must submit detailed technical data per the NAVSUP WSS Source Approval Brochure with their proposal. The Government intends to negotiate with only one source, but all responsible parties may submit proposals within 45 days of this notice. No specific budget amount or performance location is specified.
