This document is a Sole Source Justification form from NAVSUP Fleet Logistics Centers for procuring specific parts for the USNS Tippecanoe (T-AO 199) in FY 2026. The procurement involves two specific parts from Eaton Corporation: 4 Bladder, Split Tube (P/N 513565) and 48 Nuts (P/N 000110X0039), to be delivered to MSC W143 Warehouse in Norfolk, VA. The required delivery date is 9/17/25, and the procurement is a brand name requirement, with Eaton Corporation specified as the exclusive manufacturer.

The document emphasizes that these are critical safety items for propulsion and machinery control systems, and only authorized field service technicians can access and replace these parts. The parts are direct replacements that must be compatible with existing ship equipment in terms of form, fit, and function. Eaton owns all drawings and specifics for the required parts, and the components are the only approved materials specific to the brake prop shaft, which is considered critical ship equipment. The justification notes that the failure of these parts could pose a hazard to the ship, underlining the importance of sourcing from the specified manufacturer.
