No inflight refuel capability?? And what about adding a HIRSS to that unshielded engine exhaust?

We don't really have a current airframe to refuel helicopters. As far as I am aware the KC-30B will not refuel them. There is talk of several KC-130s but we will have to wait and see.

I think this will come eventually for the army versions.

Nice looking birds though and they will make a great addition to the helo fleet. Will be interesting seeing these fly from the new amphibs when they both arrive as it will finally provide Australia with a credible amphib assault capability.

As a mere "civilian" I would have thought that might be a good idea..
but then I wondered if the Europeans(and their customers) have a different understanding of the IR threat.
The Eurocopter Tiger seen here in it's Aussie Tiger form appears to have little IR suppression(Euro versions appear the same)

And as Ozair said about refuelling, be really surpised if the KC-30B was a viable platform and there is nothing else at present.

Still... it might be a good idea to put in the plumbing for a refuel probe. Joint operations may provide the tanker support otherwise lacking.

But really, in the grand scheme, this is a minor detail. The overall helicopter sounds fantastic.

Absolutely. Definitely "looks right"

I don't know a great deal about the design, but they may have a system that filters in cool air and mixes it into the exhaust as it is being expelled. They may also use materials surrounding the exhaust to help dissipate the heat. I don't know. But there are systems out there that can improve upon even these basic design features. The UH-60 actually has a fairly effective system... and the IR threat is still very serious. So I don't know if I would want to have even less than what I got!

But indeed, the IR threat is probably one of the scariest out their. You can take small arms fire and make it home, but a missile hit to the engine? That's usually a show stopper.

I'm sure the plumbing is there. The German air force CSAR version will have an AAR probe.
Exceptions confirm the rule.

I couldn't find a lot of things but from this page i did learn that it has a IR supression system which fulfills or even surpasses the requirements of the nations which ordered the NH-90.

One is for sure, with this birds Australia got some of the most modern and sophisticated helicopters around. I think they will serve well.


Btw, refueling probe is optional and can be attached.
