1.3.5 New SSJ Anchor Windlass Parts Earhart_Redacted.pdf

This document is a Commercial Only One Source Justification (NTE SAT) prepared by NAVSUP Fleet Logistics Centers in accordance with FAR 12.102(a).

The procurement involves Original Equipment Manufacturer (OEM) MacGregor USA Inc replacement anchor windlass parts for the USNS Amelia Earhart (T-AKE-6) ship's installed anchor windlass system. The requirement is restricted to a single source—MACGREGOR USA INC—with a required delivery date of June 5, 2026, and delivery to MSC BATS San Diego warehouse. The estimated cost is redacted in the document.

The justification establishes that only MacGregor, as the original equipment manufacturer, can provide certified replacement parts that meet critical safety requirements. The anchor windlass is classified as Critical Safety Items (CSI) Mission Equipment subject to American Bureau of Shipping (ABS) and United States Coast Guard (USCG) inspection requirements. The document emphasizes that MacGregor maintains proprietary design data, engineering tolerances, material specifications, and manufacturing controls necessary to ensure safe operation under rated loads per Military Sealift Command Systems procedure 10.6-002-ALL. Non-OEM parts cannot guarantee required dimensional tolerances, metallurgy standards, or load certification requirements and may invalidate equipment certification. The justification concludes that procurement from MacGregor ensures continued compliance with manufacturer specifications, preserves system integrity, and supports regulatory acceptance, with no alternative source capable of meeting government requirements without unacceptable risk to personnel safety and vessel operability.
