At random: Insignia of the Navy's submarine service is a submarine flanked by two dolphins. Dolphins, or porpoises, the traditional attendants to Poseidon, Greek God of the Sea and patron deity of sailors, are symbolic of a calm sea, and are sometimes called the 'sailors' friend. In addition to the Dolphins, those World War II submariners who participated in successful combat patrols may wear the coveted Submarine Combat Insignia.

This info came from a Sirago shipmate who lives in the S. Pacific somewhere...I think based on other emails received...Nothing new.

The boat has not yet been located and information coming out of Bali is sketchy at best.

Below is the latest news article:

 
The debris found near the waters where Nanggala was missing has confirmed the worst fear of Indonesia's search and rescue team that the German-made diesel-powered submarine was sunk off the coast of Bali, Admiral Yudo Margono, the chief of staff of the Indonesian said on Saturday.

"Based on the authentic evidence coming from KRI Nanggala-402, now we can say that the status is changed from submiss to subsunk," Yudo said in a press conference. He was using the military abbreviations for submarine missing and 'submarine sunk. 
The admiral said the search and rescue team found submarine components, including torpedo tube straighteners, coolant pipes, a bottle of periscope lubricating oil, heat-retaining sponges, and other pieces that only could have come from the submarine. 

"These are parts or components of the ship. These items belong to KRI Nanggala, they are not owned by the public, and in a radius of 100 miles, no other ships have passed," he said.

KRI Naggala-402 went missing after trying to fire its torpedoes during a combat exercise on Wednesday. The submarine last known position was in the waters over 700 meters deep, more than its maximum safe operation depth envelope of 250 to 500 meters. 
The fate of its 53 crew members is now bleak as the Navi projected its oxygen supply was only enough for three days, should the submarine remained intact and lost all its electricity. That deadline had already passed this morning. 
Despite that, Susaningtyas NH Kertopati, an Indonesian military observer, said there was still hope for the crews' survival, especially if they could breathe slowly to stretch the submarine oxygen supply. "They are trained to do that," she said.

Yudo said the SAR team was still hoping for a miracle and continue its search for the submarine. 
The search and rescue for KRI Nanggala-402 had expanded to q multi-national operations involving a ship from Singapore, a sonar-equipped frigate from Australia, and a P-8 Poseidon marine patrol aircraft from the United States. A deep submergence rescue vessel is en route from India, with a dimming hope to arrive in time to rescue any survivor.

And now, more:
BANYUWANGI – Indonesia’s military on Sunday officially said all 53 crew members from a submarine that sank and broke apart last week are dead, and that search teams had located the vessel's wreckage on the ocean floor.

“We received underwater pictures that are confirmed as the parts of the submarine, including its rear vertical rudder, anchors, outer pressure body, embossed dive rudder and other ship parts," military chief Hadi Tjahjanto told reporters in Bali on Sunday.

"With this authentic evidence, we can declare that KRI Nanggala 402 has sunk and all the crew members are dead,” Tjahjanto said.

She broke apart into 3 main pieces.

BANYUWANGI, Indonesia -- Indonesia’s military on Sunday officially said all 53 crew members from a submarine that sank and broke apart last week are dead, and that search teams had located the vessel's wreckage on the ocean floor.

The grim announcement comes a day after Indonesia said the submarine was considered sunk, not merely missing, but did not explicitly say whether the crew was dead. Officials had also said the KRI Nanggala 402's oxygen supply would have run out early Saturday, three days after vessel went missing off the resort island of Bali.

“We received underwater pictures that are confirmed as the parts of the submarine, including its rear vertical rudder, anchors, outer pressure body, embossed dive rudder and other ship parts," military chief Hadi Tjahjanto told reporters in Bali on Sunday.

"With this authentic evidence, we can declare that KRI Nanggala 402 has sunk and all the crew members are dead,” Tjahjanto said.

An underwater robot equipped with cameras found the lost submarine was lying in at least three pieces on the ocean floor at a depth of 838 meters (2,750 feet), said Adm. Yudo Margono, the navy’s chief of staff.

That’s much deeper than the KRI Nanggala 402's collapse depth of 200 meters (655 feet), at which point water pressure would be greater than the hull could withstand, according to earlier navy statements.

The wreckage is located 1,500 meters (yards) to the south of the site where the submarine last dove Wednesday, off Bali's northern coast, Margono said.

The underwater robot was deployed by Singaporean vessel MV Swift Rescue provided the images, while the Indonesian vessel KRI Rigel had scanned the area where the submarine was believed to have sank using multibeam sonar and a magnetometer, Tjahjanto said.

The cause of the disappearance was still uncertain. The navy had previously said an electrical failure could have left the submarine unable to execute emergency procedures to resurface.

An American reconnaissance plane, a P-8 Poseidon, landed early Saturday and had been set to join the search, along with 20 Indonesian ships, a sonar-equipped Australian warship and four Indonesian aircraft.

The German-built diesel-powered KRI Nanggala 402 had been in service in Indonesia since 1981 and was carrying 49 crew members and three gunners as well as its commander, the Indonesian Defense Ministry said.

Indonesia, the world’s largest archipelago nation with more than 17,000 islands, has faced growing challenges to its maritime claims in recent years, including numerous incidents involving Chinese vessels near the Natuna islands.

The final dive of 402. Glad they located her.

RIP Submariners...

Interesting. We'll see how this plays out.

I'm sure most of us have felt the "surface action" wave effect. We all know waves have depth.

We were someplace in the western Pacific and "hiding" at 400 feet from a nasty storm on the surface. We know it was "Nasty" since we could feel the wave action at that depth.

I've also been tossed around at PD by storms while waiting for SKEDs and Soupdown was spread all over the Mess Decks (rubber mats did nothing) and people are holding on and trying to not get seasick. Waves have tremendous force to them. The sound fairwater planes make hitting the surface after the boat has been sucked out of the water and then dropped makes you think the sail is being ripped off. There was nothing the planesmen could to stop it.

I know that underwater landslides can cause pressure waves that can result in both seen and unseen surface waves. It could be possible that something like that occurred in the area and enveloped the submarine. I'm just guessing here based on this last theory. The result of what ever happen is that 53 men are dead. RIP!
