The Naval Supply Systems Command is soliciting proposals for the procurement of Thermal Batteries, MK 54 (NSN 6135-01-417-6539), which are nonrechargeable battery units required for Navy operations. The Department of the Navy seeks a firm fixed-price contract for 40 initial units with options for additional quantities in subsequent fiscal years, potentially reaching up to 125% of FY26 requirements. Key contract requirements include first article testing of 8 units, production lot testing, compliance with specific technical drawings and standards, comprehensive documentation submissions, and adherence to strict cybersecurity and information protection protocols. The source selection will be based on a lowest-priced, technically acceptable approach. The original proposal due date of November 13, 2025 has been extended to February 23, 2026, and offerors must acknowledge receipt of this amendment prior to submission to avoid rejection of their offers.

This procurement carries no set-aside designation and includes specific data submission requirements detailed in the Contract Data Requirements List, including test procedures, inspection reports, failure analysis reports, and certificates of compliance. Performance of the contract will be managed by NAVSUP Weapon Systems Support with technical oversight from the Naval Underwater Warfare Center (NUWC) Division Keyport in Washington state, which serves as the primary delivery location. The contract requires submission of preliminary test procedures within 60 days of award and pre-production test reports within 15 days of first article test completion, with monthly progress reports and compliance certificates required throughout the performance period. While specific award values are not disclosed in the solicitation documents, the procurement involves initial production of 40 units with potential expansion based on Navy requirements. Contractors must be capable of manufacturing thermal batteries in compliance with detailed specifications and delivering to NUWC Keyport facilities.
