TNI (national army of Indonesia) Commander Marshal Hadi Tjahjanto confirmed that all crew members of the KRI Nanggala-402 ship died. The ship was declared sunk in the waters north of Bali.
Hadi explained the rear vertical rudder, anchors, outer layer of the pressure body, and the crew’s safety suits had been found. This is also proof that the KRI Nanggala-402 drowned and its crew of 53 people died.
“Based on the authentic evidence, it can be stated that the KRI Nanggala has drowned and all of its crew have died,” said Hadi in a press conference on Sunday (25/4).
On the same occasion, Chief of Naval Staff (KSAL) Admiral TNI Yudo Margono said the KRI Nanggala-402 was split into three parts when it was found. In other words, some parts have detached from the main hull of the ship.
According to Yudo, the split of the ship was discovered based on the monitoring of KRI Rigel. The ship managed to get underwater contact around the first position of the sinking of KRI Nanggala-402.
He said the contact was made at a depth of 800 meters. However, due to the limited capabilities of KRI Rigel, the data was submitted to Singapore’s MV Swift Rescue.
“Then the contact was identified by MV Swift Rescue at 07.37,” said Yudo.
After that, Swift Rescue deployed the ROV (Remotely operated underwater vehicle) to follow up on underwater contacts based on data provided by KRI Rigel. Then, the Singapore ROV got visual contact with KRI Nanggala-402 at 09.04.
“And at 09.04 WITA, the Singapore ROV got visual contact at the position of 07 degrees 48 minutes 56 seconds south and 114 degrees 51 minutes 20 seconds east,” explained Yudo.
Yudo said the KRI Nanggala-402 was found at a depth of 838 meters. According to him, the sinking of the submarine was due to natural factors.
“We have evaluated this from the beginning of this incident. I believe it is not a human error, but more on natural factors,” said Yudo.
He ensured that the operational process of the KRI Nanggala-402 dive was in accordance with the regulations. All ship lights were on properly.
Yudo stated that his party would remove the KRI Nanggala-402 parts from the seabed to carry out an investigation and find the cause of the sinking of the KRI Nanggala-402.
For information, the KRI Nanggala-402 submarine lost contact at a position 95 KM from north Bali on Wednesday (21/4) at 04.30 am.
The last time the submarine made contact when it was about to dive to fire a torpedo during training.
