Overview

  • US tariffs on steel and aluminum, imposed by President Trump, are increasing the cost of building submarines for Australia's AUKUS acquisition plan.
  • Concerns grow over the US's ability to scale up Virginia-class submarine production, critical to delivering three submarines to Australia by 2032.
  • Australia faces a looming $2 billion payment deadline in 2025 to help improve US submarine shipyards, with potential requests for additional funding raising financial pressures.
  • Experts warn that transferring submarines from the US fleet to Australia could weaken American deterrence against China in the Indo-Pacific region.
  • Political uncertainty in Australia, including public scrutiny over defense spending and upcoming elections, further clouds the pact's stability and execution.
