The Air Force is conducting market research to identify potential sources capable of manufacturing this component, including procurement of parts, inspection, testing, preservation/packaging, shipping, and supply chain logistics management. Interested vendors from various business categories—including Small Business, Small Disadvantaged Businesses, 8(a) businesses, Service-Disabled Veteran-Owned Small Businesses, HUBZone Small Businesses, and Women-Owned Small Businesses—are encouraged to respond. Potential sources must submit a completed Source Approval Request (SAR) package electronically through DoD SAFE by January 20, 2026, with the pre-solicitation notice posted on January 13, 2026, and a final response deadline of January 21, 2026. This sources sought effort is market research only, and no solicitation or contract award is guaranteed at this stage.

This procurement carries no set-aside designation and has identified an estimated requirement of 20 units of the linear valve. The NAICS code is 336413 (Other Aircraft Parts and Auxiliary Equipment Manufacturing) with a size standard of 1,250 employees, and the place of performance is Tinker Air Force Base in Oklahoma. The pre-solicitation notice does not identify any current contractors or incumbents, nor does it provide specific award values or budget ranges, as this is a preliminary market research phase. Qualified vendors should be prepared to demonstrate manufacturing capability and experience with similar aerospace components to be considered as potential sources for this future procurement action.
