The Higashikuni-Coda model no.840 Suzume or "Sparrow" (Allied code name: Coraline) was an experimental asymmetric aircraft designed to test out the potential of asymmetrical structured fighters. The HiC-840 was surprisingly effective with its combination of its Tsuginori Li-7 Thermojet engine and its underplaced Toku-Ro.2 (KR10) bi-fuel rocket motor with approximately 40 minutes of fuel.

The HiC-840 was initially built off of a piston powered HiC-84 8-Gata sentoki or "Type 8 fighter" with an shortened nose.

Notable events

On July 19th, 1951, during a flight test of the HiC-840 no°3 at the Tongying training Airbase, two Iosian YB-16a Daedalus and escort aircraft were detected en route for the airbase as a support for the Nordenvok military, as the airbase's only armed aircraft that was flight ready after a tropical storm hit the area just days before, the HiC-840 no°3 piloted by Inai Miyo attempted to intercept the bomber and its escort fighters in an effort to hold off the attack until other Hon-Kain fighters could arrive.

Inai Miyo's HiC-840 no°3 was heavily damaged upon take off but managed to take out one of the YB-16a Daedalus bombers before the main engine gave out; causing the aircraft to go into an uncontrollable spin. Inai Miyo managed to bail out from the HiC-840 with only minor injuries including a bruised leg from when the aircraft grazed her upon ejection.

This marks the only kill on record for the HiC-840 Suzume no°3.
