Engineering Support for Maritime Survivability Library (MSL) Software

The Department of the Navy Naval Sea Systems Command (NAVSEA) is seeking a sole source firm fixed price contract with Thornton Tomasetti, Inc. for continued engineering services and development of the Maritime Survivability Library (MSL) Software. The contract aims to support the advancement of a maritime lethality assessment tool that utilizes machine learning and artificial intelligence technologies. Key contract objectives include developing algorithms for lethality predictions on additional weapons and ship classes, improving multi-hit damage prediction algorithms, and creating workflow improvements to integrate MSL modules into other maritime lethality tools. Responses to the solicitation are due by 10:00 AM ET on December 3, 2024, with the primary point of contact being Tracy McDonough. The solicitation requires the contractor to provide monthly management reports, presentation materials, software user manuals, verification and validation reports, and software source code.

The contract has no specific set-aside designation and is classified under NAICS category 541511 for Custom Computer Programming Services with a size standard of $34 million. Thornton Tomasetti is the incumbent and proposed sole source contractor, having previously performed MSL-related work under four NSWCCD contracts between 2021-2024. The period of performance extends from contract award through September 30, 2025, with work to be performed at both the contractor's unclassified facility and the NSWCCD West Bethesda classified testing facility in Westlake, MD. Using another contractor would reportedly increase costs by 67.6% and cause a 13-week schedule delay, potentially preventing the program from meeting critical deadlines of April 2025 for expanded features and September 2025 for full integration. The contract represents a continuation of ongoing software development for the Maritime Survivability Library, building upon the previously released MSL v1.0.0 in September 2023.
