This opportunity is for the supply of 100 units of a flight-critical part (NSN 1R-5330-016220517-EY), with delivery required FOB Origin. Only previously approved sources are being solicited, as the government lacks the technical data to support full competition and considers it uneconomical to acquire or reverse-engineer that data. New sources must submit detailed information per the NAVSUP WSS Source Approval Brochure with their proposal, as approval timelines cannot delay the award. Offers failing to provide all required source approval data will not be considered for award. No budget amount or performance location is specified.
