Submarine K-17 was completed at the Feijenoord shipwright in Rotterdam in 1933. Two years later, she sailed to the Dutch East Indies for service in the Royal Netherlands Navy. She would serve the Royal Netherlands Navy in the Dutch East Indies for several years. On December 21st, 1941, after the colony had been invaded by the Japanese, K-17, captained by lieutenant Hans. C. Becançon, ran into an enemy mine field and sank with all 36 hands.

Search for the K-17

In 1980, a bizarre conspiracy theory was put forward by a sir Christopher Creighton, involving the sinking of K-17, Winston Churchill, queen Wilhelmina of the Netherlands, and the Japanese attack on Pearl Harbour. The idea received much public attention and provoked Hans C. Besançon, Jr., the son of the lost boat's commander and himself a retired officer of the Royal Netherlands navy, to undertake a crusade to find his father's resting place and disprove the fabrications.

In 1981, Hans Besançon jr., son of K-17's commanding officer, pursued a lead from a Singapore based treasure diver, who reported to have located a sunken Dutch submarine in the South China Sea at a depth of around 50 meters. Divers were sent down to the wreck, and reported that the submarine had sunk deeply into the mud bottom. Still, they managed to recover the steering wheel from the exposed bridge. When its serial number was checked against naval records, the boat was positively identified as K XVII. Besançon's quest and its findings had attracted considerable public attention, so when a Swedish diver, Sten Sjöstrand, reported finding another sunken submarine in 1995 that he suspected to be Dutch, the naval authorities were interested. Initiating a search for family members of the men lost on O-16, they organized an expedition to examine the wreck.

Even though the wreck of K-17 is a designated war grave, World War II wrecks such as this one are under constant threat of being commercially salvaged.
