Two Royal Australian Navy ships have finished an intensive underwater search for World War II destroyer HMAS Vampire I, without success.

New data has been collected but the wreck’s final resting place off the Sri Lankan coast remains unknown.
HMAS Vampire sank during a Japanese air raid on 9 April 1942, but the ship’s precise location has never been identified.
Nine Australian sailors died in the attack.
Roughly 150 square miles of the sea floor was scanned based on new information from local sources, accounts of survivors and photographic records from the battle in which Vampire was lost.
The hydrographic survey ship HMAS Leeuwin and the mine hunter HMAS Diamantina spent a week searching the area.
Leeuwin then turned its focus to the lip of a nearby deep sea trench.
Royal Australian Navy spokesman Captain Charlie Stephenson said the data collected improved the chances of eventually locating the wreck.
“Our search data suggest that HMAS Vampire sank up to a kilometre-and-a-half down a deep trench and is resting on the seafloor beneath where the battle took place,” Captain Stephenson said.
“If that is where the Vampire sunk, it is possible that she has been buried in sediment or even moved in sub-sea currents over the past 77 years.
“A different type of detection equipment will be required to look deeper into the trench – the type used by deep-sea commercial survey companies working mostly in the resources sector.”
Chief of Navy Vice Admiral Mike Noonan said while Vampire remained elusive, Australians should be very proud of what HMA Ships Leeuwin and Diamantina had achieved.
“Ultimately, nine Australian sailors remain lost at sea,” Vice Admiral Noonan said.
“When new information was received we had a duty to investigate.
“New data gathered will inform future searches which hopefully will ultimately close this chapter of Navy’s history.”
