– National Interest – The case for building the next generation of Royal Australian Navy (RAN) submarines in Australia begins with the stand-out attributes that make submarines so important for Australia as a whole: they must be able to operate in areas a long way from home, without air or sea control, to watch, listen, evaluate and act when necessary. Australia’s future submarine will be a unique platform, giving early warning of an adversary’s intentions and providing an excellent antisubmarine and anti-surface ship capability.
