Tibbsy, perhaps you should read a copy of problems of the "Collins class Sub" after the first left ADL. To say it was a heap of S$%# was putting it mildly. In fact they had to call in the yanks to get things sorted out. Did I say tractor under water, I will amend that, try Harvester. And that from the mouths of her crew. Now she ok,but sadly lacks enough crews to use them to their full potential. (you just wanna hope the Kiwis never get nasty)!!
