To meet the growing complexity of modern mine countermeasure missions, Forcys and Eelume have joined forces to deliver a new class of agile autonomous capability. Pairing Eelume’s manoeuvrable autonomous underwater vehicle (AUV) platform with Forcys’ integrated sonar and optical systems from Wavefront Systems and Voyis, will enables navies to locate, assess and confirm underwater threats with greater certainty across complex seabed terrain.

Together, these technologies mark a major advance in autonomous and networked mine countermeasure operations, allowing smaller and smarter systems to deliver the same certainty and coverage once limited to large, manned vessels.

Clearing and securing coastal waters, harbours and confined seabed areas remains one of the most difficult tasks faced by navies today. Conventional AUVs are optimised either for endurance or manoeuvrability, rarely both. In shallow or topographically complex terrain, these limitations create data blind spots, forcing navies to rely on slower and less certain minesweeping techniques.

Thomas Nygaard, CEO at Eelume, said, “Modern mines hide in the most challenging seabed environments — among rocks, slopes and narrow channels that traditional AUVs can’t fully access. Eelume S combines detection, classification and identification in one system, eliminating the need for ROV operations and reducing time-consuming mine sweeping through its manoeuvrability, advanced sensor suite and in-mission processing capabilities. This keeps personnel and vessels out of the minefield and makes MCM safer, faster and more efficient.”

The challenge lay in developing a compact, versatile platform that could deliver both wide-area detection and detailed inspection in any seabed environment, from open waters to confined littoral zones, without compromising range or endurance.

Forcys acts as the integrator of a powerful ecosystem of subsea technologies, bringing together proven innovations from across its group to deliver fully optimised solutions for the end user.

Through the integration of Wavefront Systems’ multi-aperture sonar Solstice and Voyis’ optical imaging systems, Forcys will enable Eelume S to achieve both the wide-area efficiency and close-range fidelity essential to modern MCM missions.

• Solstice delivers image quality close to synthetic aperture sonar (SAS) but at roughly one-tenth of the data burden and with substantially lower power demand. Its tolerance to platform motion makes it ideal for shallow-water and high-relief environments, requiring frequent manoeuvres, where SAS systems are less effective.
  
• Voyis Observer Imaging System provides high-resolution stills with true-colour representation, enabling rapid visual identification of potential threats once detected.

By acting as a single integration partner, Forcys ensures the optimal synergy between vehicle, sonar and camera systems, streamlining deployment and simplifying logistics for naval customers.

The Solution

The Eelume S platform introduces a flexible, bio-inspired propulsion system featuring dual counter-rotating propellers mounted on an articulated tail. This design grants independent control of pitch, yaw, and roll, allowing the vehicle to move fluidly around obstacles, maintain stability close to the seabed, and capture detailed sensor data in environments inaccessible to conventional AUVs.

Equipped with Forcys’ integrated sensor suite, Eelume S can perform wide-area sonar sweeps to detect and classify objects before transitioning seamlessly to close-range optical inspection for identification. The system’s compact size makes it easy to deploy from uncrewed surface vessels (USVs) for extended, fully remote multi-vehicle operations.

In trials across Norway’s complex coastal terrain, the platform demonstrated consistent area coverage and the ability to deliver actionable, high-resolution data at a fraction of the bandwidth normally required for SAS missions.

Thomas Nygaard, “We outperform traditional AUVs, not just on complex bathymetry, but also on flat seabeds because we can operate closer to the seabed and capture higher-quality images. With the Solstice MAS sonar integrated we get the best of both worlds, combining agile movement with the data quality needed to act quickly on targets.”

The Result

The integration of Eelume S with Forcys’ advanced sonar and imaging systems represents a major evolution in mine countermeasure capability.

The combined system enables Detection, Classification and Identification (DCI) from a single AUV, reducing mission time and complexity while increasing operational certainty.

The solution delivers:

• Greater operational certainty: Precise detection and identification even in confined, high-relief seabeds.
• Enhanced safety and efficiency: Reduced reliance on crewed minesweeping, minimising risk to personnel.
• Scalable autonomy: Compatibility with USVs and networked MCM concepts for coordinated multi-vehicle operations.
• Reduced data burden: Actionable information at lower bandwidth and power consumption, enabling faster mission processing.

For countries like the UK, where complex littoral zones, busy ports and vital offshore infrastructure demand reliable protection, this capability provides an agile and interoperable tool that enhances both national and NATO defence readiness.

Justin Hains, Forcys Business Development Manager, commented; “This collaboration with Eelume demonstrates how Forcys is enabling navies forces like the Royal Navy to operate more effectively in challenging environments previously considered unhuntable. The integration of Wavefront Systems MAS and Voyis imaging on the Eelume AUV delivers detection, classification and identification from a single platform, a capability proven in Norway’s fjords where traditional AUVs fail due to complex bathymetry. For UK missions at home and deployed, this means faster, safer and more reliable coverage across critical littoral zones.”

By bridging innovation and integration, Forcys and Eelume are transforming how the world’s navies see, understand, and secure the underwater domain.

Forcys, a global leader in underwater defense technology, and Cubedin, an innovator in modular infrastructure for maritime operations, are proud to announce a strategic partnership to provide rapidly deployable modular MCM solutions. To this end the companies have entered a Memorandum of Understanding (MoU) signed at EURONAVAL 2024 in Paris.

Forcys integrates and brings to the defense market world-changing solutions from leading technology partners Chelsea Technologies, EIVA, Sonardyne, Voyis, and Wavefront Systems. Forcys will harness these capabilities to deliver highly customizable, interoperable, and containerized solutions for complex naval missions.

At the core of this integration is Forcys’ MCM-in-a-box, designed and developed by EIVA. The 20-foot Cube module solution features EIVA’s Remotely Operated Towed Vehicle (ROTV). This versatile system supports a variety of payloads, enabling it to meet Mine Countermeasures (MCM) requirements as well as Rapid Environmental Assessment (REA), and Intelligence, Surveillance, and Reconnaissance (ISR) operations.

Designed with maximum flexibility in mind, the MCM-in-a-box can operate as a standalone system from any vessel of opportunity or military ship, and it is ideally suited to the Cubedin concept. “We are excited to partner with Cubedin and see our MCM-in-a-box solution incorporated into Cubedin’s modular concept,” said Antonio J. Belfiore, Senior Sales Manager EMEIA at Forcys. “This integration will make it easier to incorporate our solution into more complex C2 setups, creating seamless integration opportunities for modular military ships and making our systems readily accessible to our customers.”

Forcys is excited to announce they have been selected by Ocean Aero as a payload provider for their world-leading autonomous underwater and surface vehicle (AUSV), the Triton.

The Triton is the world’s only environmentally powered AUSV. Completely solar and wind powered, it can travel at speeds of up to 5 knots and can submerge for up to 5 days at 2 knots.

A true multi-domain workhorse, the Triton can be used as a force multiplier for defense operations, offering easy logistics, launch, and recovery while evading detection using autonomous avoidance and deep diving capabilities.

Forcys will be supplying Ocean Aero with SPRINT-Nav Mini, the world’s smallest hybrid acoustic-inertial navigation technology from its technology partner Sonardyne and Solstice, the leading multi-aperture sonar (MAS) for Autonomous Underwater Vehicle (AUV) systems, from its technology partner Wavefront Systems.

We need to maximize the value from our payloads while managing the power consumption to sustain our mission goals. This is where the technology from Forcys makes a significant difference. On our last mission, everyone was highly impressed with the Solstice MAS.”  With Forcys’ marine defense market expertise, alongside its access to many technology partners, and Ocean Aero’s many applications for the Triton, the partnership looks set to be a revolutionary and fruitful one.

Explosive ordnance, such as mines, pose a significant threat to naval operations, offshore energy projects, and other maritime activities. Traditional methods of disposing of these hazards often put personnel and equipment at risk as they require divers or remotely operated vehicles (ROVs) to approach the ordnance closely and manually initiate the detonation process.

The Initiation Transponder 6 (IT 6) from our technology partner Sonardyne, when integrated with mine neutralization devices mounted on a VideoRay Mission Specialist Defender underwater robot, provides a remote, autonomous, safe and effective solution for mine clearance operations. This technical collaboration allows for acoustic initiation and detonation from a remote location, eliminating the need for and risks associated with physical proximity to the ordnance.

The integration of the Defender and mine neutralization devices with the IT 6 represents a significant advancement in the field of explosive ordnance disposal (EOD).

How it works:

• The IT 6 is connected to a non-electric mine neutralization device, which is deployed near the contact by the Defender.
• Once the neutralization device is in place, the Defender can be maneuvered to a safe distance, typically around 1 kilometer away.
• Using Sonardyne’s Wideband 2 digital signal technology, the IT 6 receives an acoustic command to arm the charge from a surface vessel or command center. A subsequent command then initiates the shock tube and detonates the neutralization device.
• The entire process can be carried out in most weather conditions and during day or night, enhancing operational flexibility and safety.

Benefits:

• Enhanced safety: By eliminating the need for physical proximity to the contact during detonation, the combination of the IT 6 and Defender significantly reduces the risk to personnel and assets.
• Increased operational efficiency: The autonomous delivery and wireless initiation capability streamlines the process, allowing for faster and more efficient mine clearance operations.
• Versatility: The IT 6 and Defender can be used in various underwater environments, including deep-water operations, making it suitable for a wide range of clearance missions. The underwater robot is designed for more precise control of the vehicle position and orientation, heavier payloads and demanding interventions. With seven thrusters, it can move in any direction and maintain active pitch to face its target in an upward or downward orientation.

• Proven technology: Sonardyne’s Wideband 2 digital signal technology draws on a fifty-year heritage; it is field-proven, ensuring reliable and long-range underwater wireless communication. The Defender draws on VideoRay’s twenty-five years of ROV design experience and is built with power, reliability and flexibility in mind.
• Multi-shot: the IT 6 can be fired multiple times, making deck tests and practice runs affordable. In addition, if a mission is aborted the kit can be safely recovered and reused. The explosive charge and the IT 6 are only sacrificed on confirmed contacts.
• Cost: Once the initial investment has been made for the technology, the cost per deployment is significantly lower than sending personnel on each mission. If multiple ROVs are deployed, they can be controlled from one vessel or control room, thus further reducing costs.

Demonstration

In 2022, the IT 6 and the Defender were demonstrated together for the first time to the UK’s Defence Science and Technology Laboratory (DSTL) and the UAE Navy at a quarry in Wales.

The demonstration included successful detonations of a mine neutralization device, delivered by the Defender and initiated by the IT 6, from a range of approximately 1 kilometer.

As armed forces around the world move towards more autonomous operations on land, in the air and under the sea, there will be increased demand for the utilization of existing and the development of new technology.

The benefits in terms of safety, efficiency, adaptability and cost are obvious, not just in mine countermeasures; and the collaboration between market leaders, such as Forcys, Sonardyne and VideoRay, will be at the forefront of driving advances in the technology.
