For decades, Japan’s defense industry operated under a simple rule: build weapons, but don’t sell them to anyone. That era is over.
Japan is actively marketing its Mogami-class frigate to international buyers, anchored by a contract signed in April 2026 with Australia for 11 upgraded variants of the vessel. The deal represents Japan’s largest postwar defense export initiative. Mitsubishi Heavy Industries serves as the prime contractor, with the first delivery of three frigates expected by 2029.
What makes the Mogami-class worth buying
The Mogami-class frigate is designed for multi-mission operations spanning anti-submarine warfare, anti-surface engagements, and air defense, all wrapped in a stealth-optimized hull that reduces radar signatures.
The ship can operate with a crew of roughly 90 personnel. For context, comparable frigates from other nations typically require crews well north of 100. Fewer sailors per ship means lower operating costs, easier crew rotation, and faster deployment cycles.
