Obsolescence Risk and Impact: T-EPF-1

Ark.ai conducted a sustainment program analysis of the T-EPF-1 Spearhead Class Expeditionary Fast Transport Ship 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 T-EPF-1 program relies on. The program analysis focuses particularly on obsolescence risk, including obsolete NiiNs, declining procurement, and sole sourced parts.

The analysis of the T-EPF-1 program resulted in the following statistics. There are 1,841 Parts with Declining Procurement and 156 Manufacturers with Declining Procurement. The count of Obsolete Parts is 21,417 and the T-EPF-1 program is dependent on 2,861 Sole Sourced Parts.

Information about the critical vendors for the T-EPF-1 program, as well as a list of the obsolete and sole sourced parts, are included in the following tables.
