The United States Air Force is conducting market research through a Sources Sought Synopsis (SSS) to identify potential sources for the new manufacture of "TUBE ASSEMBLY, METAL" (NSN: 4710-01-508-7847NZ, P/N: 4087040), with an estimated spares requirement of 1,500 units. This is a new spares buy, not a repair requirement. The purpose is to determine if the effort can be competitive or a Small Business Set-Aside. Interested businesses, including various small business categories, are encouraged to respond by January 15, 2026. Potential sources must be capable of furnishing all labor, materials, facilities, and equipment for procurement, manufacture, inspection, testing, preservation/packaging, and shipping. They may also be responsible for supply chain management, logistics planning, and nonrecurring engineering costs. Qualification requires completing a Source Approval Request (SAR) package, with details available on sam.gov and submission through DoD SAFE. This SSS is for informational and planning purposes only; no solicitation is available, and no contract will be awarded based on this market research.
