I don't know that commonality is that big a deal between Aust and NZ. The Kiwis are going in a different direction with the Anzacs, Rifles, trg ac. It seems to me that there is little attempt at commonality, that quite often when we end up with the same equipment it is because both countries have arrived at the same procurement decision independently. Either way there is a good chance that we are going to end up with the same AOR. A joint purchase of 3 ships seems like it would make a good idea, maybe there are people on here who can explain why not.
