On November 4, 2025, Japan secured a significant defense contract to build upgraded Mogami-class frigates for the Royal Australian Navy as part of Australia’s naval modernization program, valued at approximately 10 billion AUD (6.5 billion USD). This historic deal involves Japan constructing the first three of eleven frigates, with the remaining vessels to be built in Australia, enhancing the Australian Navy’s capabilities with advanced automation and a versatile vertical launch system for various long-range missiles. Concurrently, Japan and New Zealand initiated discussions regarding the potential acquisition of similar upgraded Mogami-class frigates, marking a strategic alignment to bolster their naval capabilities amid rising maritime challenges, particularly from China. This trilateral defense collaboration among Australia, Japan, and New Zealand signifies a concerted effort to maintain a rules-based order and regional stability in the Indo-Pacific, with both nations committed to reinforcing maritime security and interoperability. The developments underscore the growing importance of strategic partnerships in addressing common geopolitical interests and enhancing collective defense capabilities in an increasingly contested regional environment.
