The submarine was ordered together with the KRI Cakra (401) of the same type on April 2, 1977.

The Nanggala was launched on September 4, 1980 at Howaldtswerke-Deutsche Werft in Kiel . The baptism took place on September 10, 1980 by Ms. Nining Sudirjo. On July 6, 1981, she was placed in the service of the Indonesian Navy and transferred to Indonesia . It was named after the weapon of the Hindu god Balarama , who appeared in the Indonesian puppet show Wayang , a plow .

The two submarines Cakra class, KRI Cakra (401) and KRI Nanggala (402) were several decades the only active submarines Indonesian Navy, between the closure of the KRI Pasopati (410; a project-613 - Submarine) in 1994 and the commissioning of the KRI Nagapasa (403; a variant of the submarine class 209 ) in 2017.

Modernizations

Nanggala was retrofitted at Howaldtswerke in Kiel in 1989. From October 1997 to June 1999 the batteries were changed in Surabaya and a Sinbads fire control system was installed . From 2010 onwards, the submarine in South Korea was extensively modernized at Daewoo Shipbuilding & Marine Engineering over two years and returned to the Indonesian Navy in February 2012. After the overhaul, Nanggala was able to launch four torpedoes simultaneously at different targets and to fire anti-ship missiles of the type UGM-84 Harpoon . After the modernization, the maximum submerged speed was 25 knots (46 km / h).

In 2016 the submarine was equipped with a sounder of Aselsan equipped.

Disappear

On April 21, 2021, after the last radio communication around 3 a.m. local time, the boat disappeared under previously unexplained circumstances on a routine mission with torpedo exercises about 51 nautical miles (95 kilometers) north of Bali . There were 53 crew members on board, the sea depth is about 700 m. The Indonesian military asked Singapore and Australia for assistance in the search. On the same day, the Indonesian Ministry of Defense announced that helicopters had discovered an oil stain in the area in which the submarine was positioned before contact was broken.

Search and location

With the Swift Rescue , a rescue ship specialized in submarines of the armed forces of Singapore set off for the last known position of the Nanggala on April 21, 2021 .

The highest-ranking admiral in the Indonesian Navy, Yudo Margono , stated that the oxygen reserves were sufficient for a three-day dive and that the oxygen was therefore expected to be depleted on April 24 at around 3 a.m. UTC + 8 (April 23, 7 p.m. UTC ). Australia supported the search with the frigate HMAS Ballarat and the utility HMAS Sirius , the United States sent a P-8 Poseidon to search for the boat and the Indian Navy set off a rescue submarine . Ships from Malaysia also took part in the search and other states declared their support.

On April 24, parts of the submarine - a torpedo hull and a bottle of lubricant for the periscope - were first found off the coast of Bali and the Indonesian Navy finally located the submarine.

The Navy then changed the status of the submarine from "missing" to "sunk". On April 25, a remotely operated underwater vehicle of the MV Swift Rescue made visual contact with the wreck and found that the boat had ruptured in three parts. All 53 crew members were pronounced dead. The wreck was located at a depth of 838 meters at the coordinates 7 ° 48 '56 "  S , 114 ° 51' 20.2"  O .
