Overview
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.

What believers are saying
- Expeditions Fund, Kima Ventures, and OVNI Capital financed Arsenals in July 2026.
- Expeditions publicly highlighted Harpoon in November 2026, signaling investor confidence and product momentum.
- European naval rearmament and undersea surveillance demand directly match Arsenals' sonar and autonomous-vehicle stack.
What critics are saying
- Defense procurement cycles punish startups; without French Ministry contracts, revenue stays zero through 2027.
- Ocean Infinity, Orca, CAMP, and Dragonfish already crowd autonomous undersea warfare buyers.
- If Harpoon misses live trials after November 2026, Arsenals becomes a demo-only company.
What makes Arsenals unique
- Founded in 2026, Arsenals pairs former French special-operations founders with naval autonomy expertise.
- Harpoon targets deployable, attritable underwater mass from air, land, sea, or subsea.
- Paris-based, 11-50 employees, Arsenals combines sensors, manufacturing, software, and hardware under one roof.
