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 neutralisation 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 neutralisation 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 neutralisation device, which is deployed near the contact by the Defender.
- Once the neutralisation device is in place, the Defender can be manoeuvred to a safe distance, typically around 1 kilometre 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 centre. A subsequent command then initiates the shock tube and detonates the neutralisation 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 neutralisation device, delivered by the Defender and initiated by the IT 6, from a range of approximately 1 kilometre.
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 utilisation 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.

In brief
One person-portable remotely operated vehicle (ROV) systems are increasingly being counted on to deliver support to expeditionary forces conducting underwater operations. Used to inspect and to help deploy payloads at significant depths, combat and EOD divers can count on these ROVs to provide intelligence ahead of a dive. Now packed with automation features, new generation micro ROVs have become precise inspection tools.
The challenge
Your warfighters are increasingly being relied upon to deploy, operate, and maintain complex tools in support of their operations. Diving teams have it harder than most as they need to deploy these tools underwater against currents, with low visibility and poor positioning references.
The solution
Developed by our technology partner EIVA, NaviSuite Mobula is a complete ROV software package with many advanced features for automatically and efficiently planning and performing ROV inspections, as well as enabling powerful data processing so operators can easily create high-quality, comprehensive data deliverables. Fully integrated from the factory with Defender ROVs from VideoRay, it provides your warfighters with a simple to use fly-by-wire control system. It delivers faster re-acquisitions and better data from which to make decisions.
The result
Combining NaviSuite Mobula with a micro ROV makes controlling the ROV a simple task. You can configure the user interface to suit your preferences. Flying the ROV is simple, simply drop a waypoint or select a set distance and direction and the ROV will automatically fly to that location. Use 2D, 3D and 4D model visualisations to improve your situational awareness. It’s also equipped with automatic sonar data cleaning and navigation processing tools that deliver improve your deliverables. In addition, it’s capable of generating fly-by videos or 3D visualisations to support your reporting and decision making. NaviSuite Mobula delivers actionable results enabling your warfighters to focus on information and not the process of acquiring it.
Forcys can enhance your experience with other innovative, advanced tools such as wireless acoustic initiation triggers, inertial navigation systems or optical systems from our technology partners at Sonardyne and Voyis. We can also support your autonomy programme with the integration of automatic target recognition using NaviSuite Deep Learning, or VSLAM computer vision, which lets you create 3D models using a single camera.
NaviSuite Mobula supports Defender ROV users, but it you would like to consider this innovative system to enhance a different platform please contact us.
We look forward to helping you with your requirement.
