SOURCES SOUGHT F-15 G-0004 R-0011 137 NIINs

The Defense Logistics Agency (DLA) Aviation is conducting market research through this Sources Sought notice to identify companies capable of manufacturing or legitimately obtaining 137 National Item Identification Numbers (NIINs) related to F-15 aircraft components and parts. The primary objective is to determine whether alternative sources exist beyond the currently approved supplier, The Boeing Company, for items spanning multiple Federal Supply Classifications including airframe structural components (FSC 1560) and various auxiliary equipment categories. Respondents are invited to demonstrate manufacturing capability or legitimate sourcing ability for the listed items by submitting responses by Wednesday, April 8, 2026. It is important to note that this Sources Sought is strictly for informational and market research purposes only and does not constitute a formal solicitation, commitment to award, or request for offers; therefore, no funds are available for response preparation, and all submissions are entirely voluntary.

This procurement carries no set-aside designation and acknowledges The Boeing Company (CAGE codes 76301, 0PXV4, and 81205) as the current approved source for these items. The notice does not specify contract award values, quantities required, delivery timelines, or other transactional procurement details, as the primary intent is to establish whether NIINs currently deemed sole source can be obtained from alternative qualified manufacturers. Any NIINs identified as non-sole source through this market research will not be considered for future procurement under this specific Sources Sought. The 137 line items encompass approximately 190 individual part/reference numbers formatted with 68-series prefixes and revision designations, indicating specialized aviation components integral to F-15 platform support and sustainment.
