The ANAO could assess the Department of Defence’s (Defence) procurement process for the acquisition of General-Purpose Frigates for the Royal Australian Navy. Following recommendations from the 2023 Defence Strategic Review, an independent review of the Navy’s Surface Combatant Fleet was commissioned by the Australian Government and published in 2024. The review recommended the acquisition of General Purpose Frigates with specified capabilities. In August 2025, the government announced that, following a competitive process, Japan’s Mitsubishi’s Heavy Industries Mogami-class frigate was the successful design. The first three vessels are to be built in Japan, with delivery to Australia from 2029 and entry into service by 2030. The remaining eight are to be constructed in Western Australia, subject to the successful consolidation of the Henderson precinct.
