If what we hear is true regarding our submarine procurement program, prejudice and outright ineptness would lead us to the conclusion that they will be a giant white elephant.
Obsolete before the first one is delivered, massively expensive because of Australia's unique requirements and very difficult to find manpower to crew from what we hear regarding our current boats, which apparently Beijing can hear when they start engines for a mission.
I may be very wrong because I have only what I read to go on but I can't help believing we may be shooting ourselves in the foot for not embracing nuclear.
Same prejudice that prevents us from building the only emissions free technology for generating affordable base load electricity.
