NAVSUP WSS Philadelphia intends to award a sole-source contract to Sikorsky Aircraft Corporation for three manifold assemblies, with delivery FOB origin. No technical drawings or data are available, and the government does not own the rights to purchase this part from additional sources. The approved source is Sikorsky; other firms must submit a Source Approval Request, but the procurement will not be delayed for SAR approval. Anticipated award is November 2026. Interested parties may submit capability statements for consideration, but this notice is not a request for competitive proposals.
