This is a Justification and Approval (J&A) document for a sole source procurement of direct replacement parts for the USS SOMERSET (LPD-25) Main Propulsion Diesel Engine (MPDE). The Southwest Regional Maintenance Center is seeking to acquire specialized components from Fairbanks Morse Defense, the original equipment manufacturer, to support a repair and maintenance drydocking scheduled for 18 August 2025. The total estimated acquisition value is $428,370.33, using FY-25 OPN funds.

The procurement includes multiple components such as wire thermocouples, turbocharger kits, bolts, nuts, gaskets, and actuators, with specific part numbers and quantities listed. Fairbanks Morse Defense is the sole source provider due to proprietary rights, patents, and compatibility requirements with the existing ship's diesel engine. The specific engine models involved are the Main Propulsion Diesel Engine Model Number 16PC2.5V STC USS SAN ANTONIO and the Colt Poleistic Model Number PC 2.5V STC. The J&A document emphasizes that no other sources can meet the critical technical specifications for these specialized replacement parts.
