The government intends to solicit and negotiate on a sole-source basis under FAR 6.302-1 for NSN 1H-4820-014212168-L1, TDP version 018, quantity 25 AY, because it does not own the needed data rights and considers buying the data or reverse engineering uneconomical. Delivery is to Portsmouth Naval Shipyard, Kittery, ME 03904. The acquisition will not use FAR Part 12 commercial-item procedures, though interested parties may identify a commercial-item solution to the contracting officer. Military and federal specifications, standards, QPLs, QPDs, and handbooks may be available through DODSSP/DAPS or ASSIST-Online, but patterns, drawings, deviation lists, and purchase descriptions are not stocked at DODSSP. All responsible sources may identify interest and capability, but this notice is not a request for competitive proposals and any decision to compete remains with the government.
