Australia will now receive three used Virginia-class nuclear-powered submarines from the United States. This change streamlines the AUKUS security pact. Defence Minister Richard Marles stated the move is cost-effective. The submarines will be in-service vessels from the US Navy stock. This decision simplifies supply chain and maintenance. The AUKUS submarine program is a significant part of Australia's defense strategy.

Australia will now forgo the purchase of a new build Virginia-class submarine and acquire another ex-US Navy boat instead.

The US has again demanded its allies step up their military budgets at a high-level international defence meeting in Singapore.
