Spanish defense technology company ARMMO Defense Technologies has officially presented its latest autonomous maritime unmanned platform — the ARW39CAT-A — at the Eurosatory 2026 international defense exhibition in Paris.
Platform Specifications
The ARW39CAT-A is an unmanned catamaran measuring 12 meters (approximately 39 feet) in length and 3.8 meters in beam. Built from composite materials in a twin-hull configuration, the vessel offers exceptional seakeeping stability and hydrodynamic performance.
According to official ARMMO data, the platform achieves a top speed of 45 to 50 knots (83 to 93 km/h), enabling rapid maneuverability within operational areas and swift response to maritime threats. Its tactical operational range extends to 540 nautical miles (approximately 1,000 km), significantly enhancing flexibility for long-range mission profiles.
Modular Mission Payload Design
The ARW39CAT-A can carry 800 to 1,200 kg of mission payload and is designed to integrate a wide range of modular systems, including:
- Sensor suites (e.g., radar, electro-optical/infrared systems)
- Communications packages
- Weapons stations
Small Drone Deployment Capability
Beyond fixed onboard payload, the ARW39CAT-A is also capable of deploying expendable unmanned systems. The vessel supports the launch and recovery of small drones during active missions to conduct reconnaissance and maritime surveillance, significantly extending the platform's overall situational awareness footprint.
Exhibition Context
Eurosatory is Europe's largest land and airborne defense exhibition. The 2026 Paris edition has attracted defense technology companies from around the world. ARMMO Defense Technologies' choice to debut the ARW39CAT-A at this prominent venue underscores Spain's growing capabilities in the field of autonomous maritime unmanned systems.
