AI Contract Overview

The U.S. Air Force, through the 423rd Supply Chain Management Squadron at Tinker Air Force Base, is conducting market research to identify qualified sources for the new manufacture of a regulating valve, part number 114500-111 and NSN 4820-00-860-4396, intended for use on B-52 platforms. This effort, identified by Notice ID FD20302700127, is a Sources Sought synopsis under FAR Part 10 and is not a solicitation; no contract award is anticipated from this posting, and no funds are available to compensate respondents. The Government is seeking information from all types of businesses—including small businesses, small disadvantaged businesses, 8(a) firms, service-disabled veteran-owned small businesses, HUBZone firms, and women-owned small businesses—to assess competition potential and determine if a small business set-aside is feasible. The required item falls under NAICS code 336413 with a size standard of 1,250 employees. Potential suppliers must be capable of full new manufacture of the valve, including procurement of component parts, inspection, testing, packaging, shipping, and management of supply chain risks such as diminishing manufacturing sources and long-lead procurement. Technical qualification requires submission of a Source Approval Request (SAR) package via DoD SAFE, adhering to the Manufacturing Qualification Requirements (MQR) and Engineering Data List referenced in the notice. Interested parties must complete and submit detailed business information, including CAGE and UEI codes, small business certifications, and ownership details, by August 10, 2026. Technical data is limited and may need to be independently acquired, while engineering drawings may be requested via a designated public sales desk. All responses must be submitted electronically and no oral inquiries or requests for solicitations will be addressed. This market research will inform future acquisition strategy and sourcing decisions without forming any binding obligations on the Government.
