Indonesia has selected the Wärtsilä ELAC KaleidoScope submarine sonar suite for its Nagapasa class. Suite provides platform with all-round underwater surveillance capabilities including detection, classification, and tracking of contacts.

Indonesia’s Nagapasa (Type 209/1400)-class submarines have been, or are being equipped with the ELAC KaleidoScope integrated submarine sonar suite from Wärtsilä ELAC Nautik, an official from the company has confirmed with Jane’s.

The setup, which is similar across all three ships in the class, consists of a cylindrical array sonar (CAS) for medium-range surveillance, a flank array sonar (FAS) for long-range surveillance, an acoustic intercept sonar (AIS) for detection and tracking of contacts, and an own ship noise measurement (ONM) equipment to monitor the noises generated by the boat.
