Grossman is not Indonesian and how are the non-Indonesians going to make sure the Chinese do not carelessly take data?

Why shouldnt the Chinese take data?

They are giving free help to Indonesia where the US was allegedly charging them $200m for the rescue operation

Yes, friendship, get experience on submarine rescue operations, build trust, yada yada. In the end thats $200m that Indonesia is saving from China's help.

At the very least China should get some underwater data.

$200m is lots of money which could improve the lives of 100 000 Chinese people if invested internally. So yes, free help from China but it should get something out of it

The countries that have worries on Chinese taking the ocean hydropgrapics data are Australia and USA rather than Indonesia. US and Aussie submarines made used of Lombak Straits very often when sailing from South Indian Ocean into South China Sea and onwards to Pacific Ocean.

All submarines sailing through Melacca straits have to be on the surface as this is a very busy and congested sea lane, which give away the positions of submarines. This makes Lombak straits the preferred sea route as submarines are not required to surface when moving in this strait thus not giving away their location and movement.

Any progress of the operation by the Chinese ?

I wonder if China could recover some submarine tech from the salvage? The sub is pretty old though, so any info is probably not that useful

I don't think so. I believe the wrecks will be lifted then towed to a new resting place at a much shallower part of the ocean that will be safe for conventional divers, who will then pick the wreck for the bodily remains of the crew along with other evidence needed.

Won't the recovered wreckage be shipped back to land to investigate the cause of the disaster?

I don't think they are interested on finding the true causes of the disaster, since they already have given the official explanation that underwater tidal waves may have caused the submarine to break up. Personally I think the reason is more like what happened to the Argentinian submarine, which is also an older German submarine that has been refitted. Some kind of fire may have broken out inside the sub. Or it can be like what happened to the Kursk, where a torpedo exploded. Any deeper investigation may turn up incompetence on part of the crew, or worst yet, of the hierarchy above them, all the things that are politically inconvenient.

The submarine wreckage will be lifted by the tug, but it won't be put on the tug, the wreck remains underwater hanging under the tug by cables, as the tug moves to shallower waters, where the wreckage will be deposited still underwater on a scuba diver safe diving depth. The procedure will have to be done three times with the sub broken into three. Divers will then scavenge the wreckage for bodies and confidential material. There is not going to be any access for the Chinese on the sub. There is nothing with regards to the PLAN retrieval fleet that suggests the wreckage will be put on deck. Or at least that's how I envisioned the operation to happen, given that you don't have larger vessels being used but you got a deep ocean tug and smaller vessels with submersibles.

News summary (translated from Chinese) :-
On the morning of May 18, local time, the Indonesian Navy and Chinese Navy held a joint press conference in Bali with a formation of life-saving ships to assist Indonesia, and Shenzhen Satellite TV News was the only Chinese media to attend. As of the same day, the Chinese side completed the first phase of the survey mission and achieved phased results.

A 3.7-kilometer-long and 2.5-kilometer-wide survey and salvage zone has been set around the wreckage, while the wrecked submarine has broken into three parts: Bow Section, Sail Section and Stern Section, and is sitting near a 38-meter-diameter undersea volcano crater.

So far, "Discovery 2" (Tan Suo 2) equipped with the "deep sea warrior" submersible carried out a total of 13 underwater operations, basically find out the wreckage of the wrecked submarine underwater status, collected a large number of pictures and video materials, successfully salvaged light components such as life rafts and other items, and timely handed over to the Indonesian side.

Shenzhen SATELLITE TV reporters noted that the Indonesian military at the press conference site showed some of the submarine debris, including radar warning receiver antenna, hydrophone array components, technical manuals on board the boat and life jackets of the crew.
