The Department of Defense, through the Defense Logistics Agency, is conducting a Sources Sought notice to identify potential sources for the procurement of hydraulic cylinders, specifically NSN 1650-00-317-5561, for the F-15 aircraft. The initiative aims to engage various businesses, including small and disadvantaged firms, to assess whether the requirement can be met competitively or if it should be set aside for small businesses, focusing on new manufacture capabilities that encompass labor, materials, testing, inspection, packaging, and logistics. This procurement is crucial for maintaining the operational readiness of the F-15 fleet, ensuring that the necessary hydraulic components are available for ongoing maintenance and support. Interested vendors are encouraged to express their intent and submit capability information, including business size and ownership status, to the primary contact, 423 SCMS, at 423.SCMS.AFMC.RFI@us.af.mil, noting that this is not a solicitation for bids and no funds are currently available.
