IHI XF9-1
IHI XF9-1 prototype low-bypass afterburning turbofan engine developed under Japan's fighter-engine technology program. Japan's ATLA describes a 15-tonne-class (at least 153 kN) afterburning prototype with approximately 4.8 m length and 1 m inlet diameter, integrating high-temperature, high-power-extraction technologies for future fighter propulsion; the record is kept at development status and does not infer a production aircraft installation.
