This opportunity is for the acquisition of 8 units of a specific part (NSN 0Q-5365-017215339-SX) with delivery FOB Origin. The part's design is unstable and undergoing major changes, making the current configuration obsolete, and only government-approved sources are currently solicited. Prospective bidders who are not already approved sources must submit detailed source approval information with their proposal, as failure to do so will result in disqualification. The government intends to negotiate with only one source, but all proposals received within 45 days of this notice's publication will be considered. No specific budget amount or performance location is mentioned in the description.
