The Nanggala was constructed to resist strain of as much as 500 meters deep, however sonar appeared to point that the submarine sank to a depth of about 850 meters, nicely beneath what’s known as “crush depth.” At that depth, even the metal hull of a submarine will nearly actually fracture from the strain.

Search crews from a number of international locations, together with the Indonesian Navy, had been searching the waters north of Bali for days. Time was of the essence, as a result of the submarine’s breathable air would have been at risk of working out as early as Saturday morning.

Admiral Yudo mentioned that the situation of the particles indicated that the submarine had not exploded, as has occurred in different deadly submarine incidents. As an alternative, the submarine cracked, he mentioned, which might be in keeping with the super strain exerted at such depths.

Whereas the Bali Sea has comparatively shallow elements, there are additionally trenches that dig deep into the earth.

Adm. Yudo mentioned it was not clear what had brought about the submarine to sink within the first place. However naval consultants mentioned it was possible that the vessel had descended sharply and quickly, on condition that it didn’t reply to sonar pings or give another indications of its whereabouts.

At about 3 a.m. on Wednesday, the Nanggala had requested permission to descend and start the torpedo-firing drill. The permission was granted, and that was the final communication with the submarine.

One of many individuals aboard the Nanggala on its ultimate journey was Col. Harry Setyawan, the commander of Indonesia’s five-vessel submarine fleet. A prime graduate of his naval academy class, Colonel Harry started his submarine profession aboard the Nanggala.
