The political and strategic ramifications of the AUKUS pact involving the US, UK and Australia continue to reverberate, but the details of how Australia will acquire nuclear-powered submarines (SSNs) have often been overlooked. There are daunting technical, industrial and financial challenges on the long road to joining that club.
Even the acquisition of conventional submarines isn’t easy and projects completed on time and budget are rare. Nuclear propulsion adds another layer of complexity and cost, and the engineering challenge has been described as more demanding than building the space shuttle. There are good reasons why SSN ownership is limited to a small group of elite nations—the US, Russia, China, the UK, France and India. (With considerable French assistance, Brazil is on track to have its first nuclear boat in the late 2020s.)
