Gday all, interesting thread and I certainly agree with many of the above comments...slight drift however since I keep reading about those "dud" Collins class subs here.
The whole Collins debacle is well documented and yes it has been a hugely expensive exercise plagued by many developmental problems. However, despite many of the well known issues of the past (and present - lack of crews etc) I am led to believe that the Collins boats have actually developed into extremely capable assets which are out there doing some very good (and interesting) work.
Sorry for the drift...continue
