About the Company

Arsenals

Autonomous attritable naval weapons and sonar

Arsenals builds autonomous, low-cost naval assets that can operate in swarms, starting with the Harpoon, and also develops sonar-based systems to detect underwater objects. Its platforms are designed to be mass-produced and attritable, with modular payloads for different missions. The company differentiates itself by focusing on scalable, swarm-style unmanned ships rather than traditional, single-asset kits, backed by veterans and early European investment. Its goal is to provide a deployable set of autonomous naval capabilities that can be produced at scale and improve underwater detection.
