Australian Nuclear Submarines

Australia is to become the only non-nuclear nation to have nuclear-propelled submarines which will be built in cooperation with the US and the UK.

It is the first initiative of a new enhanced trilateral security partnership announced by the leaders of the three nations in a joint statement today (16 September 2021).

The ANI has long followed the Australian submarine program with articles on progress with the replacement of the Collins Class submarine, including analysis and commentary on whether the decision to build diesel-electric submarines in Australia was the best solution; the costs of that decision; and the time it would take to deliver on it.

The Australian Naval Institute will continue to provide a range of reports, analysis and commentary.
