ARH Tiger, I can see why you might think Andu and Bushranger are reading from the same page, (I'll put my hand up and freely admit that I am as well), but where in the world did "you must be a member of the Labor Party" come from?
Along with Bushranger 71, I think it's absolute madness for a navy of the RAN's size to commit such huge resources to one hull. One cruise missile and the RAN - and Australia - is virtually out of the whole damn shootin' match, not just the local engagement. And for that reason, I can't see the Navy or any politician in future risking Canberra or her sister ships (and all the non navy personnel and equipment they'd be carrying) to even a medium risk.
What's the naval equivalent of hangar queen?
