Kevin deferred it arguably money was hollowed out, but it wasn't dead as an option. Naughty Kevin particularly as he is so pro deterrence, pro capability.
It was Julia Gillard and Stephen Smith that wilfully cancelled it. This was in line with the new white paper where they thought China = friend, and several military projects were canned. Nearly 3 years after canning Kevin. They really had no interest in it, they may have cancelled it even if Kevin had approved it and found money for it. Idologically they opposed it.
The also cancelled or delayed F-35, SPG, OCV, Triton. etc.
While all of those cancelled projects basically came back. The 4th AWD didn't because its not a MOTS acquisition, it was an essential part of Australia's workforce, sovereign capability. All hollowed out.
Now I just worry that we aren't seeing that kind of capability join the fleet for another 10 years. Because neither the Hunter nor Mogami, are true AWD, And they are certainly different in design from the Hobarts with minimal commonality and operations.
