Japan’s next-generation anti-ship missile program is taking shape, promising greater range and resilience for island defense.
The effort, led by Japan’s Acquisition, Technology & Logistics Agency (ATLA), combines advanced propulsion, guidance, and data-link systems in a compact, low-observable airframe.
The missile’s modular design features internal bays for mission-specific payloads and control systems, part of an “open architecture” strategy that allows rapid integration of new technologies.
The first prototype, slated for development in fiscal 2025, will be powered by the XKJ301-1 turbojet engine to test propulsion, guidance, and seeker integration.
The system is expected to engage naval targets at extended ranges while maintaining survivability against enemy countermeasures.
Expanded Trials Ahead
A follow-on phase in fiscal 2027 will test two airframes, designated A and B, to evaluate advanced sensor packages including electro-optical and infrared seekers.
These variants will also test a high-speed data-link system for networked targeting, improved flight control surfaces, and composite materials optimized for reduced radar visibility.
The program builds on Japan’s Type 12 modernization and ongoing standoff missile research.
While ATLA has not disclosed range details, the missile’s larger fuselage and turbojet propulsion suggest a significant leap beyond current surface-launched systems.
