This is a sole-source repair opportunity for an ASSEMBLY, PLATE AND CAP (NSN 7H-5910-016779934, part number NV823192-3) used in the Sub Atmosphere Control weapon system, with the Government intending to award to Hamilton Sundstrand Corp as the original equipment manufacturer and only approved source. The quantity is 1 AY, with delivery to DLA Distribution Norfolk VA in Norfolk, VA 23511. No technical drawings or data are available, and the Government does not own the rights to the data; firms not already approved must submit a Source Approval Request, but the procurement will not be delayed for that approval. The contract will have a one-year duration, and the solicitation will be issued electronically via NECO, with Buy American clauses and UID requirements applicable. All responsible sources may submit a capability statement, proposal, or quotation for consideration, but this notice is not a request for competitive proposals and the procurement is not set aside for small business.
