The Department of Defense, through the Defense Logistics Agency, is conducting a Sources Sought Synopsis to identify potential sources for the procurement of solenoid valves for F-15 aircraft. The procurement involves the new manufacture, inspection, testing, and supply chain management of these critical spare parts, which are essential for the operational readiness of military aircraft. This market research effort invites participation from all types of businesses, including large and small enterprises, to determine the competitiveness of the requirement and whether it can be set aside for small businesses. Interested parties should submit their business information to the primary contact, 423 SCMS, at 423.SCMS.AFMC.RFI@us.af.mil, as no funds are available for the requested data and this notice does not constitute a solicitation.
