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 this blog retired Royal Navy Cdr Justin Hains MBE provides a personal view on the challenges he faced as a serving officer in charge of diving. These are common challenges faced by many dive supervisors and until recently there was not much that could be done to mitigate for them. Read on to discover how our technology partner Sonardyne‘s new DiveTrack product line will make diving more effective and safer.
It wasn’t that long ago
I remember sitting in a dive boat at night, wondering if my unmarked divers would arrive safely at the pick-up point off Portland. The issue was lack of through water communications, so I was constantly running the “what ifs”. What if the divers didn’t surface in the place and at the time planned? If I wanted to recall them: how would I know my message would reach them? My rescue diver had no realistic chance of finding a casualty underwater. Without an external clue the odds were worse than 400:1.
I needed better situational awareness delivered by three broad requirements: me knowing the location of the divers; me communicating with the divers and the divers being able to communicate with me. Finally, underpinning all of this, in a worst-case scenario, I also wanted to send the rescue diver directly to a casualty without potentially fruitless and time-consuming underwater searches.
The technology that was missing all those years ago was reliable diver tracking and through water communications. Early solutions struggled with background noise and distortion, were limited to voice communications, and while solving the communications problem over reasonable distances did not provide accurate positional information to both diver and rescue boat.
Our technology partner Sonardyne’s DiveTrack provides a reliable answer to these core requirements with headroom for additional data exchange requirements in future. It is compact, neutrally buoyant in sea water, easy to use and reliable. It has been integrated with rebreathers and open circuit equipment. This is proven technology with application across all military diving from the experts in underwater acoustic tracking and communications.
The system has a low probability of intercept, and its encryption keeps transmissions secure. While there is a small chance of detection by a smaller group of adversaries the tactical advantage of having clear communications outweighs the small risk of real-time detection and exploitation.

Follow this link to read my next blog on this subject, where I will discuss how DiveTrack provides safety, operational advantage and a greater probability of mission success. The combination of improved situational awareness, even in a GPS denied environment, and the reliability of communications and positioning provide an unprecedented level of tactical flexibility in a range of operational scenarios. The risk of detection and exploitation of the encrypted signals is easily outweighed by the operational advantages of the system. Finally, should the worse happen and a diver requires assistance: the rescue diver or other divers nearby can home onto the position. The rescue diver will find the casualty.
