Patria delivers new acoustic minesweeping systems to Norwegian Navy

International defense and technology company Patria has completed the delivery of new acoustic minesweeping systems to the Royal Norwegian Navy.

The navy has been using the Patria SONAC ACS minesweeping systems since the spring of 2024. The system can simulate any ship’s sound and is suitable for mine setting mode (MSM) and target simulation mode (TSM).  

Patria developed the system using its knowledge of vessel signature measurement, influence mine technologies, and minesweeping. According to the company, the remote operation of the acoustic sweeping gear is easy and simple in real-time.

During the mission, the operator selects the desired acoustic signal from a signature library and initiates the acoustic sweeping with it. Alternatively, the operator can design a custom signal for acoustic sweeping when needed.

During the sweeping, smooth operation is enabled by a user-friendly interface that provides controls and settings for the sweep as well as views to monitor the status of the system, the firm added.

“We are excited to operate Patria SONAC ACS as part of our MCM influence mine sweeping system following the recent retirement of our high-end ELMA-AGATE sweep. SONAC ACS has so far offered excellent handling and very promising performance, operation and reliability. The Norwegian Navy considers this new influence minesweeping capability as one of the most sophisticated influence minesweeping in service today,” squadron commander, Commander Bengt Berdal, said.
