PARIS, — June 18, 2026 : Ukraine has unveiled a new unmanned surface vessel (USV) named SIRENA at the Eurosatory 2026 defense exhibition in Paris, showcasing a multi-role maritime platform that combines electronic warfare, reconnaissance, and air defense capabilities within a single autonomous system.
The SIRENA trimaran was presented by Ukraine’s state-owned defense trade enterprise SpetsTechnoExport in cooperation with the Center of Innovative Technologies Program. Designed specifically for operations in confined and contested maritime environments, the platform is intended to support coastal defense, surveillance, electronic warfare, and counter-air missions.
Multi-Role Maritime Platform
Developed to address evolving maritime security requirements, the SIRENA integrates advanced sensors, electronic warfare equipment, and missile-based air defense systems on an unmanned vessel. The platform is capable of conducting reconnaissance missions, disrupting enemy systems, and engaging aerial threats while operating without exposing personnel to frontline risks.
According to information presented at the exhibition, the vessel can operate autonomously, semi-autonomously, or through remote control, providing flexibility for different mission profiles. It does not require a direct line-of-sight connection with its command center, allowing it to operate deep inside contested maritime zones.
Performance and Endurance
The SIRENA has been engineered for long-range and extended-duration missions.
Key specifications include:
- Maximum speed of 90 km/h (56 mph).
- Operational range of up to 800 kilometers (500 miles).
- Continuous endurance of up to 24 hours at sea.
- Payload capacity of up to 300 kilograms (660 pounds).
- Autonomous, semi-autonomous, and remote-control operating modes.
These characteristics enable the platform to conduct prolonged coastal surveillance, electronic suppression missions, and maritime patrol operations.
Advanced Electronic Warfare System
A central feature of the SIRENA is its integrated Scorpion V5 electronic warfare system, designed to disrupt enemy communications and navigation networks.
The system operates across a frequency spectrum ranging from 300 MHz to 6,000 MHz (6 GHz) and can simultaneously interfere with multiple categories of targets, including:
- Military communication networks.
- GNSS navigation signals.
- Autopilot and navigation systems.
- Drone command-and-control links.
Exhibition representatives stated that the Scorpion V5 is particularly effective against unmanned aerial threats, including Shahed-type loitering munitions. The system can reportedly conduct electronic suppression at distances of up to 30 kilometers, providing a protective electronic shield for maritime operations.
Radar and Air Defense Capability
Beyond electronic warfare, the SIRENA is designed to function as an active air defense platform.
The vessel is equipped with the Pelican V1 radar, which provides target detection, tracking, and situational awareness. The radar works in conjunction with the vessel’s weapon system to identify and engage aerial threats.
For kinetic engagements, the trimaran carries the SeaDRAGON launcher, which is configured to fire AIM-9M Sidewinder air-to-air missiles adapted for naval deployment. This capability allows the unmanned vessel to engage hostile aircraft, helicopters, and drones operating in the vicinity of maritime forces or coastal infrastructure.
The combination of radar-guided detection, electronic warfare effects, and missile-based interception gives the platform a layered approach to countering aerial threats.
Designed for Contested Maritime Environments
Representatives of the Center of Innovative Technologies Program stated that the SIRENA was specifically developed for operations in areas where traditional naval assets may face elevated risks from drones, missiles, or electronic attack.
Its trimaran configuration provides stability for carrying radar, electronic warfare equipment, and missile systems while maintaining high-speed maneuverability. The vessel's modular architecture also offers flexibility for future upgrades and mission-specific payloads.
Continued Development of Ukrainian Unmanned Systems
The introduction of the SIRENA reflects Ukraine's ongoing investment in autonomous maritime technologies and unmanned warfare capabilities. The system builds upon the country's growing experience in developing uncrewed surface vessels for reconnaissance, strike, and support missions.
At Eurosatory 2026, detailed information and renderings of the platform highlighted the integration of the Pelican V1 radar, Scorpion V5 electronic warfare suite, and SeaDRAGON launcher with AIM-9M Sidewinder missiles, demonstrating a multi-domain approach that combines sensing, electronic attack, and air defense functions on a single unmanned vessel.
The SIRENA's combination of long-range operation, electronic warfare capabilities, and missile armament positions it as a versatile platform for coastal defense, reconnaissance, and maritime security operations in increasingly contested littoral environments.
