Australian Government Concludes Contract with MHI for Joint Development and Production of Australia's New General-Purpose Frigates

Australian Government and Mitsubishi Heavy Industries, Ltd. (MHI) concluded a contract, for the construction of three upgraded Mogami-class frigates for Australia's General Purpose Frigate (GPF) program.

In August 2025, the Australian government selected MHI's upgraded Mogami-class frigate (4,800 ton type) as the preferred platform to proceed to the next stage in the selection process for the country's GPF program. MHI then entered into contract negotiations with the Australian government, and has now concluded an agreement.

Construction will begin at MHI's Nagasaki Shipyard & Machinery Works in cooperation with the Australian government, the Japanese government, and companies involved in building the GPFs, with the first completed frigate to be handed over by December 2029.

The broad-based participation of Japanese and Australian companies in Australia's GPF program is expected to strengthen human resource development in science and technology, as well as the foundations of the defense industry, in both countries. Through its Naval Ship & Maritime Systems business, MHI is contributing to the realization of safe and secure world.
