He urged against speculation about potential causes.
”There was a catastrophic impact on the helicopter when it hit the water,” Marles said.
”We will move through the process of putting the Black Hawks into service as quickly as we can ... and we will not be flying MRH90s until we understand what has happened,” Marles added.
Australia’s fleet of more than 40 of the MRH-90 Taipan helicopters, made by French Airbus, has been grounded since the crash and there are doubts any will fly again.
They will be grounded until crash investigators determine what caused the tragedy.
The government announced in January it plans to replace them with 40 US Black Hawks. The Taipans’ retirement date of December 2024 would be 13 years earlier than Australia had initially planned.
The lost Taipan had been taking part in Talisman Sabre, a biennial US-Australian military exercise that is largely based in Queensland state.
This year’s exercise involves 13 nations and more than 30,000 military personnel.
The exercise was continuing today with some changes near the recovery operation, Australian Defense Force Chief General Angus Campbell said.
Campbell thanked the United States and Canada for their help in the search and recovery efforts, which he said was “not an easy operation”.
The wreckage lay in the path of strong currents and tidal movements. It was too deep for standard diving operations.
Part of the airframe had been retrieved today but most of the helicopter remained on the seabed, Campbell said.
It was the second emergency involving an Australian Taipan since March. The fleet was grounded after one ditched into the sea off the New South Wales state coast near the naval base at Jervis Bay during a nighttime counterterrorism training exercise.
All 10 passengers and crew members were rescued.
Retired Major General Fergus McLachlan was involved in integrating the Taipan into the Australian army when they arrived in 2007 and had been responsible for keeping them airworthy.
He said the Taipan did not have the proven record of the Lockheed Martin-designed Black Hawks.
”We bought into an unproven system. In real terms, it was a developmental aircraft and it has never really matured,” McLachlan told the ABC.
”It was always a battle to maintain it and keep it flying,” McLachlan added.
