Purchase Order N0016726P1007

The Naval Sea Systems Command awarded a $250K firm fixed-price purchase order to Thornton Tomasetti, Inc. on November 7, 2025, for Maritime Survivability Library (MSL) Software Support services. This contract, with an ultimate completion date of October 31, 2026, supports the continued development and enhancement of the MSL software program—a machine learning-based tool that predicts maritime weapons damage probability and integrates with related maritime lethality tools including Target Damage Cards, INSiTE, and SUBVALUE. Key technical deliverables include developing algorithms for lethality predictions on additional weapon characteristics and targets, improving multi-hit damage prediction capabilities, creating workflow improvements, and performing verification and validation testing. Monthly deliverables will encompass technical reports, presentations, software user manuals, source code, and verification reports. The contract was procured on a sole-source basis with no small business set-aside designation.

Thornton Tomasetti, a New York City-based global engineering design and analysis firm with approximately 1,200 professional staff, is well-positioned to execute this work given its extensive experience in maritime survivability software development, advanced computational modeling, and technical consulting for naval systems. The company has secured numerous federal contract awards from the Naval Sea Systems Command and other defense agencies, with prior work encompassing ship shock survivability analyses and maritime lethality prediction tools. Primary work will be performed at the contractor's facility in New York, NY, with occasional testing at the Naval Surface Warfare Center Carderock Division's West Bethesda facility in Westlake, Maryland.
