She was in Tokyo Bay on September 2, 1945, one of ten Royal Australian Navy ships present when the Japanese signed the instrument of surrender aboard the USS Missouri. A 680-ton Bathurst-class corvette -- small enough to disappear among the cruisers and destroyers gathered for that historic morning -- HMAS Ipswich had earned her place. Five battle honours spanning three years and two oceans hung from a service record that would have been remarkable for a warship twice her size. But the strangest chapter of her career lay thirteen years in the future, in waters she had never been designed to patrol, under a flag she had never been built to fly, when a black-painted bomber with no markings would end everything.

On April 28, 1958, a Douglas B-26 Invader appeared over Balikpapan in southern Borneo. It was painted black and carried no markings. The aircraft struck KRI Hang Tuah with bombs, and the old corvette that had survived five theaters of World War II went to the bottom off the harbo...

The wreck of KRI Hang Tuah -- once HNLMS Morotai, once HMAS Ipswich -- lies near the entrance to Balikpapan harbour, in waters where oil tankers still come and go. She was one of sixty corvettes built to fight a desperate war, and she outlasted most of her sisters only to be dest...
