Patria’s acoustic mine sweep is specially designed for sweeping influence mines with advanced acoustic triggering. Its compact, lightweight size is designed for use with unmanned craft. The streamlined cylindrical tow body is designed to minimise drag while also allowing mounting onto an external frame or to be used together with a float.

The all-electric SONAC ACS requires only a three-phase 440 VAC power supply and communication interface (Ethernet is preferred).

SONAC ACS is able to produce high sound pressure over a large frequency range (from infra- to ultrasonic bands), essentially capable of effectively simulating any ship. SONAC ACS is especially suitable for target simulation mode (TSM) because it can transmit any acoustic waveform signals.

The command protocol of SONAC ACS allows dynamic re-programming (for example, changing the acoustic signature) and control of the settings and operation of the acoustic sweeping gear. The operator can either create a new or select a previously generated/recorded acoustic signal for each mission. The signal can then be sent to the sweeping gear. The protocol also allows the operator to monitor the operation and status of the acoustic sweep during the mission.
