The Department of Defense is seeking sources for a specific rotating assembly component (NSN 3120-014828716) with OEM Northrop Grumman. Interested suppliers who are not the original manufacturer must provide full traceability information back to the OEM with their response. This is an informational sources sought notice only, not a solicitation, and does not obligate the government to award a contract. No funding is available to cover the cost of preparing responses.
