Obsolescence Risk and Impact: LCAC-1

Ark.ai conducted a sustainment program analysis of the LCAC-1 Landing Craft Air Cushion program, examining the vendors, their suppliers, manufacturers, shippers, and other members of the supply chain – as well as the critical parts and NiiNs the LCAC-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 LCAC-1 program resulted in the following statistics. There are 6,830 Parts with Declining Procurement and 1,074 Manufacturers with Declining Procurement. The count of Obsolete Parts is 76,935 and the LCAC-1 program is dependent on 15,481 Sole Sourced Parts.

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