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.
