Maritime Survivability Library (MSL) Software Engineering and Support Services

The contract involves the continued development, engineering, and support of the Maritime Survivability Library (MSL), a specialized software tool used by the Navy for lethality assessment and damage prediction. The Naval Surface Warfare Center Carderock Division intends to award a firm fixed price contract on a sole source basis to Thornton Tomasetti, focusing on enhancing algorithms, expanding target and weapon support, improving user interfaces, and integrating MSL with other Navy systems such as TDC, INSiTE, and SUBVALUE. The work includes delivering technical reports, user manuals, source code, and providing training and knowledge transfer to government personnel. The contract is set for a performance period of one year, from November 1, 2025, to October 31, 2026, with all deliverables to be inspected and accepted at the government’s facility in Bethesda, Maryland, with inspection occurring at both origin and destination. The contractual framework incorporates a comprehensive set of FAR and DFARS clauses, many incorporated by reference, covering security, prohibitions on certain hardware and software, supply chain security, information safeguarding, and compliance with cybersecurity standards. The contract emphasizes strict adherence to government standards for data, verification, and validation, with deliverables including monthly reports, technical documentation, and source code, primarily via electronic submission. Payment procedures are managed through the Wide Area Workflow system, with specific instructions for encryption and notification. The award will be based on a Lowest Price Technically Acceptable approach, requiring quotes to demonstrate technical acceptability and offer the lowest price among compliant submissions. The contract also specifies detailed inspection and acceptance procedures, with final approval at the government’s facility, and mandates compliance with security and confidentiality requirements. Overall, the contract aims to sustain and advance the MSL software’s capabilities to support Navy maritime lethality assessments, ensuring rigorous technical, security, and administrative standards are met throughout the performance period.
