Obsolescence Risk and Impact: M113

Ark.ai conducted a sustainment program analysis of the M113 Armored Personnel Carrier program, examining the vendors, their suppliers, manufacturers, shippers, and other members of the supply chain – as well as the critical parts and NiiNs the M113 program relies on. The program analysis focuses particularly on obsolescence risk, including obsolete NiiNs, declining procurement, and sole sourced parts.

The analysis of the M113 program resulted in the following statistics. There are 3,521 Parts with Declining Procurement and 83 Manufacturers with Declining Procurement. The count of Obsolete Parts is 28,223 and the M113 program is dependent on 5,357 Sole Sourced Parts.

Information about the critical vendors for the M113 program, as well as a list of the obsolete and sole sourced parts, are included in the following tables.
