Greyshark AUV Sensor Trials

Euroatlas, a German company, has finished propulsion tests for its Greyshark autonomous underwater vehicle (AUV) and will soon begin sensor trials. These sea trials will validate the AUV's functionality in various applications.

Applications

The Greyshark AUV is designed for multiple tasks, including:

Mine warfare
Underwater infrastructure monitoring
Intelligence gathering on vessels
Detection of underwater threats

The trials are scheduled for May.

AUV Specifications

The Greyshark has the following specifications:

Length: 6.5 m
Diameter: 1.5 m
Weight: 3,500 kg
Depth rating: 650 m (with a goal of 4,000 m)

Its non-metallic hull contributes to a low sonar signature, enhancing sensor accuracy. It features various sensors, including an electromagnetic sensor array (EMSA), synthetic aperture sonar (SAS), multibeam forward-looking sonar (FLS), laser imaging and measurement system (LIMS), multibeam echosounder (MBES), and a high-resolution underwater camera. Communication is facilitated by a telescopic antenna with military radio and an anti-jam GNSS system.

Germany's Euroatlas has successfully completed propulsion tests for its Greyshark autonomous underwater vehicle (AUV) and will now move on to carry out sensor trials of the equipment.

Speaking to Janes at the IMDEX 2025 naval and defence exhibition in Singapore, Euroatlas' overall project manager for the Greyshark project Niko Schmidt disclosed that these sensor trials will be carried out at sea to begin validating the various functions envisioned for the Greyshark AUV.

These include mine warfare, monitoring of underwater infrastructure, intelligence gathering on vessel activities, and detection of potentially hostile underwater threats.

The trials are presently scheduled to take place in May, Schmidt said.

The Greyshark is an under-development AUV with a length of 6.5 m, a diameter of 1.5 m, and a weight of 3,500 kg. It currently has a depth rating of 650 m but the long-term goal is to increase this to 4,000 m.

Given its non-metallic and non-pressurised hull, the Greyshark AUV is said to have a low own-sonar signature, which increases the accuracy of the various sensors that it can be fitted with.

These include an electromagnetic sensor array (EMSA), a synthetic aperture sonar (SAS), a multibeam forward-looking sonar (FLS), a laser imaging and measurement system (LIMS), a multibeam echosounder (MBES), and a multispectral high-resolution underwater camera.

To communicate with the operator and other units, the AUV is equipped with a telescopic antenna system with built-in military radio and an anti-jam global navigation satellite services (GNSS) system that assists the Greyshark in carrying out its autonomous sailing operations.
