BRAND NAME JUSTIFICATION REDACTED.pdf

This document is a NAVSUP Fleet Logistics Centers Sole Source or Brand Name Justification form for Mission Support Materials. The procurement is specifically for CAT Diesel Engine Model 3608 direct replacement spare parts for LPD-17 Class SDGs (Ship's Service Diesel Generators), with a required delivery date of 12/17/25. The materials are technically authorized for use on existing Caterpillar Diesel Engine 3608 per technical manual S9311-D1-MMC-020, Volume 2, Revision 3, and will interface with the existing LPD-17 Class Ship's Service Diesel Generator system.

The justification for sole source is based on proprietary technical data and intellectual property held by Caterpillar Inc., which prevents open-source procurement. The OEM has exclusive technical information on engineering drawings and performance characteristics, and is unwilling to share item specifications. The procurement follows specific technical requirements from SRF-JRMC guidelines, with the goal of preventing counterfeit assemblies during repair and overhaul of the LPD-17 Class SDGs. The document indicates this procurement precludes competition to the maximum extent practicable.
