The government seeks four units of NSN 7R-1650-015238307-H1 under TDP version 002, FOB origin, with early and incremental deliveries accepted. It intends to solicit and negotiate with only one source under FAR 6.302-1, and this notice is not a request for competitive proposals. All responsible sources may nevertheless identify their interest and capability or submit proposals, quotations, or capability statements for consideration in determining whether to conduct a competitive procurement. The government is not using FAR Part 12 commercial-item procedures, though interested parties may identify commercial-item interest and capability to the contracting officer. Technical documents are available through DODSSP/ASSIST-Online, but patterns, drawings, deviation lists, and purchase descriptions are not stocked at DODSSP.
