The Albanese Government has taken a major step towards delivering a larger and more lethal surface combatant fleet with contracts now signed for Australia’s first three general purpose frigates.

Built by Mitsubishi Heavy Industries (MHI), the ships will be of the upgraded Japanese Mogami class frigate design, with the first scheduled to be delivered to the Royal Australian Navy in 2029.

The Albanese Government is working closely with the Japanese Government and industry with future ships to be constructed in Western Australia, subject to consolidation of the Henderson Defence Precinct, in line with the Government’s commitment to continuous naval shipbuilding.

Defence is also working with Japanese industry and the Japan Maritime Self-Defense Force to develop an initial capability to sustain and operate the upgraded Mogami class frigates in Australia, supported by Australian industry and workers.

The upgraded Mogami class frigate has a range of up to 10,000 nautical miles and a 32-cell Vertical Launch System. It will be equipped with surface-to-air and anti-ship missiles, crewed by 92 Royal Australian Navy sailors and officers, and capable of operating Navy’s MH-60R Seahawk maritime combat helicopter.

The decision to acquire upgraded Japanese Mogami class frigates accords with the Albanese Government’s commitment to more than double the size of Navy’s surface combatant fleet, following the 2024 independent analysis of Navy’s surface combatant fleet. In the 2026 Integrated Investment Program released this week, the Government committed to the investment of up to $20 billion over the decade into general purpose frigates.

The contract-signing was marked by the Deputy Prime Minister and his counterpart, the Japanese Minister of Defense, Koizumi Shinjirō signing the ‘Mogami Memorandum’, reaffirming the Australian and Japanese Governments’ shared commitment to the successful delivery of Australia’s general purpose frigates and deeper defence industry cooperation.

Royal Australian Navy personnel trained with the Japanese Maritime Self-Defense Force aboard the Mogami class frigate Japan Ship Kumano during its transit to Australia for Exercise Kakadu, further strengthening interoperability and the longstanding defence relationship between Australia and Japan.

The next two decades will see tens of billions of dollars invested in defence capabilities in Western Australia, including the build of future upgraded Mogami class frigates at the Henderson Defence Precinct, supporting around 10,000 high-skilled jobs.

Quotes attributable to Deputy Prime Minister, Richard Marles:

“Acquiring upgraded-Mogami class frigates demonstrates the Albanese Government’s focus on investing in the capabilities we need to keep Australians safe.

“Our surface fleet is more important than at any time in decades. These general purpose frigates will help secure our maritime trade routes and northern approaches as part of a larger and more lethal surface combatant fleet.”

Quotes attributable to Minister for Defence Industry, Pat Conroy:

“This is the fastest acquisition for the Royal Australian Navy in peacetime. We are working closely with Japanese and Australian industry partners as we acquire one of the most, if not the most, advanced general-purpose frigate in the world.

“We are delivering these commitments at pace, supporting and creating jobs for Australians, and deepening Australia’s industrial base. The first three frigates will be built offshore in Japan. We will then transition to an onshore build in line with the Government’s commitment to continuous naval shipbuilding and a future made in Australia.”
