Brand Name Justification_Redacted.pdf

This document is a Sole Source/Brand Name Justification form from NAVSUP Fleet Logistics Centers for procuring spare parts for a Caterpillar Diesel Engine. The procurement is specifically for direct replacement spare parts to repair #2 & #5 Ship's Service Diesel Engine Generator (SSDG), a CAT Diesel Engine Model 3608, currently installed on LPD-22. The required delivery date is 12/15/25, and the manufacturer is Caterpillar Inc. (CAGE:11083), located in Peoria, IL.

The justification highlights that Caterpillar has proprietary technical data, engineering drawings, and performance characteristics that were solely developed and funded. The OEM is not willing to share item specifications to support an open source procurement. The technical requirements mandate using Caterpillar's specific technical manuals and drawings (T/M S931-D1-MMC-020, Vol 2, REV-3) to ensure proper interface with the existing SSDG system and prevent counterfeit assemblies from being installed. The document indicates that this is a brand name requirement and that the proposed parts represent the minimum requirements of the government.
