The government is conducting market research to identify potential sources for the production of the C-5 Hydraulic Motor and Screw Drive Motor, which are used on the C-5 Galaxy military transport aircraft. The original equipment manufacturer, Eaton Aerospace LLC, is the only known source with the necessary technical data and capabilities, as the government does not own manufacturing data packages for these non-commercial items. The DLA/AWB Contracting Office intends to award a sole source contract to Eaton Aerospace LLC for these items. Interested parties must identify their interest and capability by 26 Jun 2026. No budget information or performance location is specified.
