WWI mystery solved as wreck of sub found
sydney — Australia’s most enduring military mystery has been solved after the wreckage of the country’s first submarine was found more than a century after it vanished off Papua New Guinea, officials said on Thursday.
HMAS AE1, the first of two E Class submarines built for the Royal Australian Navy, disappeared on 14 September, 1914 near the Duke of York Islands with 35 crew members from Australia, Britain and New Zealand on board. It was the first Allied submarine loss in World War I.
AE1 was found in more than 300 metres of water after an expedition — the 13th such search — was launched last week using Fugro Equator. “After 103 years, Australia’s oldest naval mystery has been solved,” Defence Minister Marise Payne told reporters in Sydney.
“This is one of the most significant discoveries in Australia’s naval maritime history... The loss of AE1 in 1914 was a tragedy for our then fledgling nation.”
Payne said she hoped the discovery would help investigators establish the cause of the sinking.
Rear Admiral Peter Briggs said the most likely cause of the loss “remains a diving accident”, The Australian newspaper reported.
“The submarine appears to have struck the bottom with sufficient force to dislodge the fin from its footing,” it quoted Briggs as saying.
He said the vessel appeared to have suffered a “post sinking, high energy event” that would have caused the submarine to flood rapidly, probably near the surface.
The newspaper pointed to a possible torpedo explosion or the rupture of a high-pressure air cylinder.
“When the end came for the men of AE1 it would have been very fast. They may well have not known what hit them,” Briggs said.
Construction for AE1 started in 1911 and she was commissioned in Portsmouth, England in February 1914. The sub reached Sydney in May with her sister AE2.
At 55 metres long, AE1 displaced 599 tonnes and could reach a top speed of 15 knots on the surface and 10 knots when submerged. She was armed with four 18-inch torpedo tubes. — AFP
