Obsolescence Risk and Impact: CVN-68

Ark.ai conducted a sustainment program analysis of the CVN-68 Nimitz Class Aircraft Carrier program, examining the vendors, their suppliers, manufacturers, shippers, and other members of the supply chain ‚Äì as well as the critical parts and NiiNs the CVN-68 program relies on. The program analysis focuses particularly on obsolescence risk, including obsolete NiiNs, declining procurement, and sole sourced parts.

The analysis of the CVN-68 program resulted in the following statistics. There are 36,087 Parts with Declining Procurement and 4,102 Manufacturers with Declining Procurement. The count of Obsolete Parts is 256,518 and the CVN-68 program is dependent on 92,776 Sole Sourced Parts.

Information about the critical vendors for the CVN-68 program, as well as a list of the obsolete and sole sourced parts are included in the following tables.
