About this opportunity
The Defense Logistics Agency Aviation has published a Limited/Sole Source Justification Notice for the acquisition of KC-135 Motor Pump hydraulic components (NSN 1650-01-161-159HS/7318228A) to support aircraft maintenance operations. The justification is based on Hamilton Sundstrand Corporation (CAGE 99167) being identified as the sole source manufacturer capable of fulfilling this requirement, with market research conducted in August 2024 confirming no other viable sources exist. The acquisition is justified under AMSC D classification, indicating that technical data is not economically available from other sources, requiring direct procurement from the original manufacturer. The contract was awarded on June 27, 2025, for a quantity of 642 units under a firm-fixed-price arrangement, though the specific contract value has been redacted from the documentation. The justification process included posting a Sources Sought notice in July 2024, which received only one vendor response, further supporting the sole source determination for these critical aircraft hydraulic system components.
