ZOKA – Acoustic Torpedo Countermeasure Jammers and Decoys purchased by Indonesia from ASELSAN have arrived in Indonesia.  ZOKA's delivery to Indonesia was completed on October 22, Janes reported.

The ZOKA order, which will be used on Nagapasa class (Type 209) submarines in the Indonesian Navy inventory, was announced in March 2019.

The ZOKA effectors are capable of operating effectively against any torpedo threat that has acoustic homing capability operating in active, passive or combined modes. The combined use of ZOKA decoys and jammers has been highly effective against acoustic torpedoes.

State-owned shipbuilder PT PAL will be working with engineers from Aselsan to integrate the system onboard all three Nagapasa-class platforms.
