At present, the Indonesian military has dispatched several warships to search in the incident waters. In addition, the Indonesian military has requested Singapore and Australia, two countries with submarine rescue boats, to assist in the search. Searchers found oil leakage on the water, probably because the fuel tank was damaged or a distress signal was sent out. The Indonesian Navy said in a statement: The submarine may have power failure during diving, resulting in the interruption of the control system and the inability to implement emergency procedures. Nangala? It may sink into the deep sea of 600 to 700 meters. ? An Indonesian official said? Nangala? The design maximum diving depth of "No.1" is 250 meters. ?

There is a trench 700 meters deep below the lost location. At present, there is only one suspected site map on the Internet, and the oil pollution on the sea surface is concentrated. If it really came from a wrecked submarine, it should be that the pressure shell collapsed at a relatively shallow depth, not necessarily a cliff. The limit dive depth of 209/ 1300 is 250 meters, but considering the age of 402 and the poor maintenance level of Indonesian navy, it is unlikely to go down to this depth. It is reported that torpedo live-fire launching training was being carried out at that time. If it is true, objectively, there may be an accident during the launch process, which will lead to seawater backflow from the torpedo tube (this accident has also happened in history and caused the death of the boat).

In addition, normally speaking, the crew of 209/ 1300 is only 32 people. What is the submarine? A radish and a pit? There will be no major changes in the number of staff. At present, most news reports that 53 people are missing with the ship, and it is estimated that there are temporary personnel on board.

I don't know if this old ship is equipped with an emergency communication system, that is, something that can automatically float to send messages in an emergency. (I forgot the specific name) If it has been installed, I haven't received the news ... It is estimated that things will be a bit serious ... It is theoretically feasible to escape through the torpedo tube, but the problem is that the water depth is too deep. So far, no floating escape personnel have been found, so it seems that the accident happened quickly; Maybe the weapon really blew itself up or the ship was seriously flooded?
