The Navy intends to award a sole-source contract to Sikorsky Aircraft Corporation for four manifold assemblies (NSN 7R-1650-017257552-H5, P/N 06650-04875-107), with delivery FOB origin. The government does not own the drawings or data rights needed to procure this part from other sources, so any unapproved manufacturer must submit a Source Approval Request, and the procurement will not be delayed for approval. The solicitation will be conducted under FAR Part 15 using electronic procedures, and this is not a small business set-aside. Interested responsible sources may submit capabilities statements for consideration, and the anticipated award date is November 2026. All responsible sources are encouraged to respond.
