Requesting NH-90/MRH-90 Maintenance Estimates

Hi, I’m doing a project on the MRH-90, Australian version of the NH-90, and I was wondering if there is any information regarding:

Airworthiness
Downtime
Training Time
Operational Readiness
Maintenance Hours per Flight Hours

So far all searches on the net seem to be bleak since its not yet operational.
The same went for searches on the NH-90 as well, information on either would be welcome if anyone knows 🙂
