Japan's new-generation multi-mission frigate with advanced stealth design, representing a radical departure from previous JMSDF surface combatant concepts. Displacement of 5,500 tonnes full load with a highly automated crew of just 90 — approximately half that of comparable vessels, achieved through extensive automation and unmanned systems integration. Features a faceted stealth hull form with enclosed mast and reduced radar cross-section. The FFM is designed for mine countermeasures (incorporating an Unmanned Surface Vehicle and Unmanned Underwater Vehicle mine hunting system), anti-submarine warfare, and surface combat. Armed with Mk 41 VLS for ESSM and VL-ASROC, 8x Type 17 anti-ship missiles, 1x Mk 45 Mod 4 127mm gun, SeaRAM CIWS, and torpedo tubes. Features the OPY-2 AESA multi-function radar and OQQ-25 sonar system. 22 ships planned — the largest JMSDF surface combatant programme in decades.

- Highly automated; 90-person crew vs. 200+ on comparable frigates
- 22-ship class provides massive fleet renewal for JMSDF
- Stealth shaping reduces RCS significantly
- Mine countermeasures capability built-in; replaces dedicated MCM fleet
- OPY-2 radar is advanced Japanese AESA system
- Only 16-cell VLS; limited air defense magazine for frigate-sized ship
- Mine countermeasures role may compromise combat warfighting optimization
- New OPY-2 radar unproven in fleet operations
- 76mm gun light for a 5,500-tonne warship

SIGN INThe crew ergonomics improvements here translate directly to reduced decision latency under fire.
Mobility cross-country is more operationally significant than top speed on paved surfaces. This platform understands that.
Electronic warfare suite depth is what separates this from comparable platforms in its class.
