This opportunity is for the acquisition of two units of a specific part (NSN 7R-4920-016010080-QE) that requires engineering source approval due to its flight-critical nature and limited technical data. Only previously approved sources have been solicited, and new sources must submit detailed qualification information as outlined in the NAVSUP WSS Source Approval Brochure to be considered. Delivery is FOB origin, and the government intends to negotiate with only one source under FAR 6.302-1, though all responsible parties may submit proposals. Proposals will be considered if received within 45 days of the synopsis publication, but award cannot be delayed for new source approval. No specific budget amount or performance location is specified in the description.
