The government seeks to acquire 6 units of a specified NSN part, FOB origin, restricted to a source-controlled/selected-item drawing source. No suitable technical data, Government data rights, or manufacturing/repair knowledge are available to permit acquisition or repair by other sources, qualification testing of another part, or use of a second-source part. The proposed action is intended for sole-source negotiation under FAR 6.302-1, though responsible sources may submit interest, capability statements, proposals, or quotations for consideration. This notice is not a request for competitive proposals, and any determination not to compete based on responses is solely within the Government’s discretion. The acquisition will not use FAR Part 12 commercial-item policies, but interested parties may identify commercial-item interest and capability to the contracting officer.
