How many nuclear-powered submarines for Australia?

Summary

KEY POINTS:

1. Since the 2009 defence white paper, successive reviews have affirmed the need for 12 submarines.
2. It takes three to four submarines to guarantee having one available for deployment.
3. A force of 18 subs—nine on each coast—would be even more resilient.
