The KRI Nanggala (S-402) is a submarine of the Indonesian National Armed Forces , which in the 2021 Bali Sea disappeared. It was the second unit of the submarine class 209-1300 built in Germany for Indonesia , which is called the Cakra class in Indonesia .

history

The Nanggala was launched on September 4, 1980 at Howaldtswerke-Deutsche Werft in Kiel . 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 Cakra-class submarines, KRI Cakra and Nanggala , were the only active submarines in the Indonesian Navy for several decades, between the 1994 decommissioning of KRI Pasopati (a Project 613 submarine) and the Commissioning of KRI Nagapasa (a variant of the submarine class 209 ) in 2017. Nanggala was retrofitted in 1989 at Howaldtswerke. About two decades later, the ship was extensively modernized in South Korea over two years and returned to the Indonesian Navy in February 2012. After the overhaul, Nanggala was able to fire four torpedoes simultaneously at different targets and to fire anti- ship missiles such as Exocet or Harpoon . After the modernization, the top speed was 25 knots (46 km / h) (submerged).

Disappear

This article describes a recent event . The information can therefore change quickly.

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 are 53 crew members on board and the sea depth is around 700 m. The Indonesian military asked Singapore and Australia to help with the search. On the same day, the Indonesian Ministry of Defense announced that helicopters had discovered an oil spill in the area of ​​the sea in which the submarine was positioned before contact was broken.

With the Swift Rescue , a rescue ship of the Singapore armed forces specializing in submarines set off for the last known position of the Nanggala .

On April 22, 2021, an admiral of the Indonesian Navy declared that - assuming a crew of 53 people - the oxygen reserves had been used up without additional surfacing one day after the last contact on board.
