The primary issue with the Tiger is the support side of the equation has been woefully inadequate. Australia is not alone here, the deployment to Afghanistan for instance required a herculean effort from, not just the operators, but Eurocopter as well. I have been told that there was no analysis of the spares required, they simply predeployed multiple examples of every part they had, filling an entire warehouse in theatre.But how much would they get for $1 billion? (BTW that seems an awful lot to upgrade them.. ). Judging from the Korean order, less than 18?
How operational are they now, I had thought by now with the French having operated them off a LHD in combat operations and the Germans operating them in 'Ghan things were finally looking up for them? I don't think we would be junking them.
To bring the Tiger up to the required standard (support systems included) as well as meeting the evolving needs of the ADF is probably approaching the cost of a replacement. The required upgrades would likely also leave Australia with an even more unique, orphan version with even less commonality with other Tigers, further complicating and increasing the cost of support. This would make new build Zulus, or Apache Echos, bought through and supported by FMS, with the potential to hook into US spiral development programs, far more attractive than persisting with Tiger.
