The CXXM400 Unmanned Surface Vehicle (USV) is a compact, high-performance unmanned marine platform designed for professional maritime missions where remote operation, payload flexibility, and extended communication are required.
Available in Standard and Ultra configurations, the CXXM400 combines a 115 HP gasoline outboard engine, aluminum-alloy hull, 350 kg payload capacity, and long-range operating capability. The Ultra version reaches a maximum speed of 45 knots, making it suitable for missions that require rapid deployment across large water areas.
The platform can operate as an individual USV or as part of a coordinated unmanned system involving multiple vessels, relay UAVs, command vehicles, and ground control stations.
The CXXM400 is designed to move quickly between designated operating areas.
The Standard configuration reaches 35 knots, while the Ultra configuration provides a maximum speed of 45 knots. Even with a full payload, the Ultra model can reach approximately 40 knots.
This performance provides greater flexibility for time-sensitive maritime operations.

The platform supports a maximum payload of 350 kg, providing sufficient capacity for a broad range of professional equipment.
Depending on the mission, customers can integrate:
The open configuration allows the USV to be adapted without changing the basic vessel platform.

The CXXM400 has a specified endurance of approximately 100 nautical miles (185 km) when operating at 20 knots.
A 100-liter fuel tank supports extended missions and reduces the need for frequent refueling during normal operations.
Actual range will vary according to speed, payload, weather, water conditions, and operating profile.
The CXXM series is designed for remote operation through a ground control station.
With an antenna installed at approximately 700 m, the system can achieve a line-of-sight communication range of up to 100 km under suitable conditions.
For projects requiring wider coverage, an optional relay UAV can be introduced. With the relay platform operating at approximately 700 m, the communication architecture can extend coverage to around 200 km.
Rather than being limited to one specific application, the CXXM400 serves as a configurable unmanned maritime platform.
Payload and onboard systems can be selected according to project requirements, making the vessel suitable for different combinations of observation, surveying, monitoring, communication, and emergency-response functions.
The CXXM series can support coordinated deployment of multiple USVs.
A typical system can combine:
USV Fleet + Relay UAV + Ground Control Station + Command Vehicle
This architecture allows operators to coordinate multiple unmanned platforms and manage maritime missions from a centralized control system.
