Like our car industry it seems the only good reason the government has to build our new subs (and to have built the Collins) in Adelaide is that we need to maintain a national manufacturing / engineering capability.
Should that come at the expense of national security however?
Our Collins has been a turkey in just about every sense. A deterrent and capability on paper only. I think on average we've only had one boat fully manned and sea-worthy at any one time for a number of years. Lucky we've had the US floating by and no adversary except NZ kayakers. Obviously that will change in the coming years with the emergence of China and other minor SE Asian powers responding. Add India.
I like the idea of us building our own boats. Long range conventional things that we can build and maintain, that our Baby Boomer no-nuclear NIMBY type would sign off on. However, as with the Collins, it will without doubt be a colossal failure and waste of resources that could be pushed into Pink Batts and the like. At a time when we really actually do need to be developing this capability. We can't get this one wrong.
Any thoughts from the ASF Defence mindful community, or BB NIMBYs?
