This opportunity is for the procurement of 4 units of a specific part (NSN 7R-5999-016637553-EY), with delivery required FOB origin. The government intends to solicit and negotiate with only one source, as it does not own the data rights to purchase or repair the part from other sources and reverse engineering is uneconomical. All responsible sources may submit capability statements or proposals within 45 days of this notice’s publication to be considered. No budget amount is specified, and no drawings are available for this requirement. The location for performance is not specified.
