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.
