History

Developed to replace the OH-6 in the scout role, the OH-1 first flew in 1996 powered by two Mitsubishi turboshafts. It entered limited service with the Japan Ground Self-Defense Force from the turn of the century.

Variants

The production OH-1 has remained close to its prototype configuration, with study proposals for armed and re-engined derivatives that were not pursued in quantity. It retains its distinctive shrouded tail rotor throughout.

Where you'll see it

It serves solely with the Japan Ground Self-Defense Force in the armed reconnaissance role and has no UK counterpart in service, the British Army having used the Gazelle and later Wildcat for scouting.
