Diver Detection Sonar

We are a maritime high-technology enterprise with German roots and a global footprint. The know-how and expertise of our skilled workforce in the fields of hydroacoustics, sensor engineering and information technology have made us the preferred supplier to numerous navies and civilian customers worldwide. As a specialist for underwater acoustics, we are the market and technology leader in many sectors.

We have the capability of integrating different kinds and makes of equipment into a system-of-systems architecture. With that, we have mastered the entire functional chain from sensor to shooter. As a result, we can provide the users of our systems with precise decision criteria. Every day, we work on expanding our stock of knowledge, applying this know-how to the benefit of our customers, and constantly becoming a better company.


This fibre-optic guided, one shot mine disposal vehicle is used for semi-autonomous disposal of naval mines and other ordnance found at sea. It is able to automatically relocate previously acquired positions of underwater objects within minutes with the integrated homing sonar.After relocating, these objects can be identified using the onboard CCTV camera and destroyed by the use of a built-in, large caliber shaped charge. The one-way concept significantly reduces the disposal time and extends the operational envelope.

The system has been fully qualified for military purposes and has been introduced in large numbers into various navies. It is deployable from a wide range of carrier platforms, including dedicated MCM vessels, surface combatants, craft of opportunity, rubber boats and helicopters.

The SeaFox system is a mine disposal system based on the most advanced concept using the Expendable Mine Disposal Vehicle principle (EMDV).
Small, unmanned underwater drones are used for direct disposal of historical and most modern mine types; identical, reusable vehicles (without charge) are used for inspection, identification and training purposes.

The system is effective against long and short tethered mines, proud ground mines and floating mines.
The SeaFox system mainly comprises a console, a launcher and the SeaFox vehicles. The system can be delivered as a stand-alone or a fully integrated version.

In case of stand-alone the console contains all electronics, software, displays and operating elements to guide the vehicle automatically or manually towards the target and to relocate, identify and destroy it. In the fully integrated version, a Multi Function Console or any existing console can be used.
The two different vehicles ensure quick disposal of mines during operation with the combat vehicle (SeaFox C) as well as cost-saving identification with the reusable identification version (SeaFox I).


The ATLAS ELEKTRONIK Hull-Mounted Sonar (HMS) systems ASO 713/723 belong to the ASW sonar family in the 4th generation. More than 100 of these superior sonar systems have been sold over the past 30 years.

ASO is designed for active and passive operations in the medium frequency band with the main focus on surveillance of the underwater situation, such as detection, classification and tracking of targets. With the ability of different operational modes and parameter settings, ASO systems are optimised for the detection of targets from littoral (shallow) to blue (deep) waters. Advanced processing methods ensure their efficient use for classic ASW tasks as well as self-protection of the surface combatant.

The ASO sonar is capable of detecting:

  • Submarines as well as midget- and mini-submarines
  • Small underwater vehicles, such as AUV, UUV and diver delivery vehicles
  • Torpedoes
  • Underwater obstacles, such as moored mines
  • Speed boats
