Event Summary

Fleetzero, a U.S.-based marine technology developer, has announced a collaboration with Thoma-Sea Marine Constructors, a U.S. shipbuilder, and Glosten, a naval architecture and marine engineering firm. This partnership aims to accelerate the development and deployment of integrated autonomous vessel solutions for commercial maritime, government, and defense customers. The collaboration combines Fleetzero's marine power and autonomy stack, including its Leviathan Battery Energy Storage System, with Thoma-Sea's shipbuilding capacity and Glosten's vessel design expertise. The companies are developing an autonomous diesel-electric vessel with minimal radar cross-section, designed for use in contested waters, persistent operations, and supply delivery. This initiative aligns with priorities from the United States — United States Department of Defense, United States — Small Business Administration, and United States, supporting the national objective of delivering electrified, autonomy-ready hulls from domestic shipyards. Fleetzero's recent $43 million Series A funding round in 2025, backed by investors like Y Combinator, Italian Founders Fund, Evan Williams (Internet entrepreneur), A.P. Moller–Maersk, and MOL Plus, supports this expansion.
