SAR Efforts Underway for Indonesian Submarine

According to the latest reports, KRI Nanggala (402) — a diesel-electric attack submarine of the Indonesian Navy, one of two Cakra-class submarines (Type 209 design) — had lost contact in the sea 95 km north of Bali on April 21, 2021, and had 53 crew members. It was conducting AEG SUT 264 torpedo firing drills when the communication was lost in an area that was up to 700 meters deep in the sea.

"After permission was given according to the procedure, the submarine lost contact and could not be reached," the Indonesian defense ministry said.


The Indonesian Navy subsequently sent a distress call to the International Submarine Escape and Rescue Liaison Office (ISMERLO) around 09:37 WIB to report the boat as missing and presumably sunk. The navy stated that Nanggala might have experienced a power outage before falling to a depth of 600–700 m (2,000–2,300 ft).


At the time it went missing, Nanggala had 53 people on board, including 49 crew members, one commander, and three weapons specialists. Admiral Yudo Margono, the Indonesian Navy chief of staff, said the search was being aided by calm conditions but the crew's air supply would last only until Saturday.
