The Government intends to solicit and negotiate with only one source for 75 units of a specific part, as it is uneconomical to obtain the necessary data or rights for competitive repair or reverse engineering. All responsible sources may identify their capability, and proposals received within 45 days (30 days under an existing BOA) after the synopsis publication will be considered. Interested parties may also identify their ability to meet the requirement with a commercial item within 15 days. Documents are available online via ASSIST-Quick Search or through the DoD Single Stock Point in Philadelphia, PA.
