1.2.2 N6275843277472 JA_redacted.pdf

This is a Sole Source Justification and Approval document for the procurement of a Lea Stern Tube MX9 Shaft Seal Assembly (Item H72252-01) for the Ship Repair Facility and Japan Regional Maintenance Center (SRF-JRMC) in Yokosuka. The procurement will be conducted as a firm fixed-price supply contract with Defense Maritime Solutions, Inc. (DMS), operating under cage code 0SYN4 (formerly Wartsila Defense Inc.).

The justification explains that DMS is the only authorized manufacturer for this OEM-restricted component, which is essential for maintaining watertight integrity of the ship's propulsion system. The part must be compatible with existing seal assembly tube shafts and propulsion systems, with failure risks including potential leakage exceeding 1.6 gallons per minute. Market research through SAM.gov and other sources confirmed no other authorized distributors exist, and while small businesses may inquire, they lack authorization to produce or provide this component. The solicitation is expected to be posted around 2/27/25 with quotes due around 3/7/25, to be managed by Naval Supply Fleet Logistics Puget Sound (N00406).
