NOTHING quite prepares you for the sheer scale of an Air Warfare Destroyer. To appreciate it properly, you have to see it out of the water. I spent a morning this week clambering around the first of the navy's three AWDs. It's being built in Adelaide by ASC in collaboration with several other companies. It was pouring with rain and everywhere on the ship was wet. The AWD is just too big to be built indoors. Like all modern warships, it is full of kilometres of working cables and narrow, awkward corridors.
