Like the classic German U-boat film, Australia’s submarine program looks to be languishing on the bottom of the ocean. This week we dive, dive, dive into the depths of Scott Morrison’s ham-fisted handling of our French alliance and just what we can expect from the AUKUS agreement. What sort of subs might we get, what will our partners expect in return, and how are the neighbours going to respond with the idea of an Australian nuclear navy? And are the Collins class subs really that bad? Stand by to blow ballast while we see if we can bring these tin cans’ troubles to the surface.
