Obsolescence Risk and Impact: B-21

Ark.ai conducted a sustainment program analysis of the B-21 Raider 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 B-21 program relies on. The program analysis focuses particularly on obsolescence risk, including obsolete NiiNs, declining procurement, and sole sourced parts.

The analysis of the B-21 program resulted in the following statistics. There are 722 Parts with Declining Procurement and 16 Manufacturers with Declining Procurement. The count of Obsolete Parts is 6,348 and the B-21 program is dependent on 2,335 Sole Sourced Parts.

Information about the critical vendors for the B-21 program, as well as a list of the obsolete and sole sourced parts, are included in the following tables.
