In a landmark defense agreement, Australia will invest US$6 billion to acquire 11 advanced Mogami-class frigates from Japan's Mitsubishi Heavy Industries, marking one of Japan's most significant defense export deals since World War II. The announcement, made by Defense Minister Richard Marles on Tuesday, represents a major step in Australia's strategic military modernization efforts in the Indo-Pacific region.
Strategic Partnership and Naval Expansion
The procurement is part of Australia's ambitious plan to expand its naval fleet from 11 to 26 major warships over the next decade. This expansion aligns with Australia's broader strategic positioning in international relations, particularly in response to regional security challenges.
Advanced Military Capabilities
The Mogami-class frigates feature advanced stealth technology and impressive offensive capabilities, including:
- 32 vertical launch cells for long-range missiles
- Advanced stealth technology
- Next-generation combat systems
- Tomahawk cruise missile capability
Strengthening Regional Alliances
This deal further solidifies the growing security partnership between Australia and Japan, both members of the Quad alliance alongside India and the United States. As Australia continues to strengthen its Indo-Pacific partnerships, this military procurement represents a significant shift in regional defense cooperation.
"This is clearly the biggest defense-industry agreement that has ever been struck between Japan and Australia," stated Defense Minister Richard Marles, emphasizing the strategic importance of the deal.
Timeline and Implementation
The first Mogami-class vessel is expected to be operational by 2030, replacing Australia's aging Anzac-class fleet. The total investment of AUS$10 billion will be distributed over the next decade, representing one of Australia's most significant defense acquisitions in recent history.
