This opportunity is for the procurement of 8 units of a flight-critical item (NSN 7R-2835-015665097-SX), with delivery required FOB origin. The government holds complete technical data rights, but only previously approved sources are solicited due to flight-criticality and incomplete data for full competition. New sources must submit detailed technical and production experience information via the NAVSUP WSS Source Approval Brochure with their proposal, or their offer will not be considered. Approval for new sources typically takes too long to allow for a delayed award, and the government may proceed based on fleet support needs if approval cannot be processed in time. No specific budget amount or performance location is mentioned.
