The U.S. Navy intends to award a sole-source contract to Sikorsky Aircraft Corporation for the purchase of 2 units of a DUCT ASSEMBLY (NSN 1R-9999-LLJ9QQ949-CB), as the government lacks data or rights to source from other suppliers. Delivery will be FOB Origin, and the anticipated award date is November 2026. All responsible sources may submit a capability statement, proposal, or quotation within 45 days of this synopsis for consideration. Firms not already approved to manufacture this material must submit a Source Approval Request (SAR), but the procurement will not be delayed for SAR approval. The location for performance of services is not specified.
