Loading trials were carried out between a C-17A Globemaster and an Army MRH-90 from 10-11 May 2015.
Chief Petty Officer Richard Booth, of Headquarters Forces Command, said the procedures would apply to both Army and Navy "Taipans".
“We now have the ability to transport an MRH-90 and its support equipment if required to almost any theatre in the world,” Chief Petty Officer Booth said.
“This capability will allow the Navy to support short-notice deployments for several scenarios as and when they occur.”
He said the trial was conducted slowly to start with, then more quickly as issues were resolved.
The design work for operationally loading two MRH-90s into a C-17A is yet to begin.
When cleared, the ability to load two in each C-17A will provide a rapid deployment capability to the Australian Defence Force.
Preparation included removing the helicopter’s rotor blades, horizontal stabiliser and external lights and antennas.
The MRH-90 tail can also be ‘folded’, a feature to assist crews when operating from a ship.
“We discovered the tail needs to be folded and unfolded twice during the process of loading and lashing the aircraft into the C-17,” Captain Jeremy Mellor, of the Reconnaissance and Air Mobility Systems Program Office, said.
“This is to ensure sufficient clearance between the helicopter and the ground and the C-17A’s upper ramp.”
Navy's MRH-90 helicopters are bases at 808 Squadron at HMAS Albatross in Nowra New South Wales.
