This.Tigre works for some -The French have proved that. Certainly the optical sensor fit is very good, the weapons work and it has provided valuable support to ground troops in Afghanistan etc. For a country that's often accused of being risk adverse, they do a lot of fighting with it, far more than anyone else with it. What it doesn't have is the Longbow radar and I suspect various black boxes that allow it to network with other allied helos. Is that a major downside ? Yes if you are going to be operating with the conflict majority shareholder - Uncle Sam - as a "network aware" asset and all that mullarkey. Now, would the good old US allow that functionality to be implemented on a commercial rival ? Especially those outside the old trusty collective ? Be an interesting exercise.
For the Australians, there is no point in putting right a variant which may be out on a limb in a conflict with regards other allied airborne assets regarding interoperability and spares.
