The wreckage of a submarine was found in the Bali Sea. Submarine KRI Nanggala (402) was at a depth of 850 meters. This depth already exceeds the capabilities of the submarine. It is designed for depths of up to 500 meters.
The submarine had a crew of 53 people. It is reported that the supply of oxygen there was supposed to run out on the morning of Saturday 24 April. Therefore, the probability of finding someone alive is close to zero.
Rossiyskaya Gazeta suggests that KRI Nanggala (402) is unlikely to be raised from the depths. Therefore, what caused the tragedy, we may never know.
