who is advising these pollies in the first place? Surely our ADF chiefs can't be recommending the purchase of these Barracuda lemons in waiting. Retrofitting a nuclear designed submarine to accommodate diesel engines is an absolute joke. Australia needs to drop this rubbish policy of no nuclear and get with the times. Invest in something decent like the typhoon class subs - make use of our alliances with the most technologically advanced military power on the planet ffs
