Canberra – Australia has chosen Japan to construct a fleet of next-generation warships in a landmark $6 billion (Rp 98.2 trillion) deal, signaling a significant shift in its defense strategy and a deepening security partnership with Tokyo. The agreement, announced Tuesday by Defense Minister Richard marles, will see the purchase of 11 Mogami-class frigates from Mitsubishi Heavy Industries.
“This is clearly the largest defense industry agreement ever agreed between Japan and Australia,” Marles stated, highlighting the scale of the collaboration. Mitsubishi Heavy Industries secured the contract, surpassing competition from German firm Thyssenkrupp Marine Systems.
The decision comes as Australia undertakes a major overhaul of its military, focusing on long-range strike capabilities to counter the growing influence of the Chinese navy. The Mogami-class frigates are designed as sophisticated stealth warships, equipped with advanced weaponry including 32 vertical launch cells capable of deploying long-distance missiles, and are expected to be capable of launching Tomahawk cruise missiles.
These new vessels will replace AustraliaS aging Anzac-class frigates, with the first Mogami-class warship anticipated to be operational by 2030.Defense Industry Minister Pat Conroy emphasized the impact of the acquisition, stating it will make the Australian navy “bigger, and more deadly.”
This move builds on Australia’s broader defense initiatives, including a 2021 agreement to acquire nuclear-powered submarines from the United States, replacing a previously planned deal with France. The combined investments underscore Australia’s commitment to bolstering its naval power and strengthening alliances in the Indo-Pacific region.
What are the potential benefits of technology transfer from Japan to Australia regarding Australia’s defense industry?
Japan to Construct Australia’s Next Generation of Warships
The Landmark Defence Partnership
Australia and Japan have solidified a groundbreaking defence agreement: Japan will lead the construction of Australia’s next generation of warships,marking a notable shift in australia’s naval capabilities and regional security dynamics. This collaboration, announced in early 2024 and now progressing rapidly in 2025, centers around the growth and building of a new class of frigates, perhaps based on Japan’s advanced Mogami-class multi-role frigates. This represents a major step in the Australia-Japan security relationship, fostering deeper interoperability and technological exchange.
Project Details: SEA 5039 phase 4
The project, formally known as SEA 5039 Phase 4, aims to replace Australia’s aging Anzac-class frigates.Key aspects of the program include:
Warship Type: While not definitively confirmed, the Mogami-class frigate is the leading contender. This vessel boasts advanced stealth technology, a refined combat management system (CMS), and the capacity to undertake a wide range of missions, including anti-submarine warfare (ASW), anti-surface warfare (ASuW), and mine countermeasures.
Construction Location: A significant portion of the construction will take place in Australia, specifically at the Osborne Naval Shipyard in South australia. This commitment to local build is crucial for developing australia’s sovereign shipbuilding capabilities. japanese industrial partners will work alongside Australian companies, facilitating knowledge transfer and skills development.
Technology Transfer: A core component of the agreement is the transfer of advanced shipbuilding and defence technology from Japan to Australia. This will not only enhance Australia’s naval capabilities but also create a enduring,high-tech industrial base.
Timeline: The first warships are anticipated to enter service in the early 2030s. the program is expected to span several decades, ensuring a continuous pipeline of advanced naval vessels for the Royal Australian Navy (RAN).
Estimated Cost: The project is estimated to cost upwards of AUD $30 billion, making it one of australia’s largest defence investments.
Why Japan? Advantages of the Partnership
Australia’s decision to partner with japan on this critical project stems from several key advantages:
Technological Prowess: Japan is renowned for its advanced shipbuilding technology and its commitment to innovation in naval warfare.the Mogami-class frigate represents a cutting-edge design, incorporating the latest advancements in stealth, sensors, and weapon systems.
Proven Reliability: Japanese naval vessels are known for their reliability and operational effectiveness. This is a crucial factor for Australia, which requires warships capable of operating in a demanding maritime habitat.
Strategic Alignment: Australia and Japan share a common strategic outlook and a commitment to regional security and stability. This shared vision strengthens the foundation for a long-term defence partnership.
Industrial Collaboration: The partnership fosters closer industrial collaboration between Australia and Japan, creating economic opportunities and strengthening bilateral ties.
Reduced Risk: Leveraging an existing, proven design like the Mogami-class reduces the technical and program risks associated with developing a entirely new warship class from scratch.
the introduction of these next-generation frigates will substantially enhance Australia’s naval capabilities in several key areas:
Enhanced Anti-submarine Warfare (ASW): The frigates will be equipped with advanced sonar systems and ASW weaponry, improving Australia’s ability to detect and counter submarine threats.
Improved Air defence: The vessels will feature sophisticated air defence systems, providing enhanced protection against aerial attacks.
Increased Littoral Warfare Capabilities: The frigates will be well-suited for operating in littoral (near-shore) environments, enabling Australia to project power and protect its maritime interests.
Greater Interoperability: The frigates will be designed to operate seamlessly with other Australian defence Force assets and with those of key allies, including the United States and Japan.
Expanded Maritime Domain Awareness: Advanced sensors and surveillance systems will provide enhanced maritime domain awareness, enabling Australia to monitor and respond to threats more effectively.
Sovereign Shipbuilding and Australian industry Involvement
A central tenet of the agreement is the commitment to maximizing Australian industry involvement. This will be achieved through:
Local Construction: A significant portion of the warships will be constructed at the Osborne Naval Shipyard in South Australia, creating thousands of jobs and stimulating economic growth.
Supply Chain Opportunities: Australian companies will be given opportunities to participate in the supply chain, providing components, systems, and services for the frigates.
Skills Development: The project will drive investment in skills development and training, ensuring that the Australian workforce has the expertise needed to support the construction and maintenance of these advanced warships.
* Technology Transfer: The transfer of technology from Japan will enable Australian companies to develop their own capabilities in advanced shipbuilding and defence technology.
