This is a sole-source supply action for 105 units of a specific NSN part, with delivery FOB origin, requiring engineering source approval from the design control activity. Only approved sources may supply the part due to data rights and technical knowledge not economically available to the Government; alternate sources must undergo Government-approved qualification. The Government intends to solicit and negotiate with only one source under FAR 6.302-1, but all responsible sources may submit capability statements for consideration. Interested parties may also identify if they can satisfy the requirement with a commercial item. No budget amount is specified, and no performance location is stated beyond FOB origin.
