The Government intends to solicit and negotiate with only one source for the supply or repair of six parts, as technical data is not available to permit acquisition from other sources. All responsible sources may identify their interest and capability, with proposals considered if received within 45 days. Interested parties may also identify their capability to satisfy the requirement with a commercial item within 15 days of this notice. Documents can be obtained from the DoD Single Stock Point in Philadelphia, PA, or online.
