The MRH90 is deployable in the C-17. It
can be carried intact with no disassembly - simply fold main and tail rotor. The OEM has not yet certified it to be carried in the C-17 in this condition (even though the ADF has done it a few times already for deliveries from France). A tech airworthiness decision to be made by the ADF, perhaps?
Of note, the RAN is about to receive the first of 2 LHDs - these will be the primary method of deploying MRH90's long distances, and supporting them once they get into theatre.
As for RAST etc, the MRH90 will not be fitted with RAST, nor will it be fitted with powered blade fold. The operating envelope has been demonstrated to be quite reasonable with the manual blade fold. MRH90 can be fitted with floats (BIG ones) and the RAN has already demonstrated that they work !
The NH90 (NFH) would have been compatible with RAST, ASIST and HARPOON.....
