As the AUKUS inquiry reveals, Pillar One isn’t the only route to SSNs

Why it matters

The independent AUKUS Public Inquiry has validated low-enriched uranium (LEU) nuclear submarines as a strategic option, undercutting the false binary that only Pillar One (HEU-fuelled Virginia/SSN-AUKUS boats) can deliver Australia's required 12-boat SSN fleet. This opens a policy pathway that could accelerate sovereign capability delivery and mitigate the 2030s–2040s capability chasm identified in the current plan, directly strengthening Maritime Defence (Pillar 6) and reducing strategic dependence on US industrial capacity (Pillar 7).
