History

Designed by Mitsubishi in 1934–1935 and first flown in 1935, the Ki-18 was a clean low-wing monoplane powered by a Kotobuki radial engine. Despite achieving impressive speed figures, the Army preferred the biplane Ki-10, favouring manoeuvrability over speed — a decision that would prove costly years later.

Variants

Only a single prototype was built; no production variants followed.

Where you'll see it

The Ki-18 never entered production or operational service, having lost the evaluation to the Kawasaki Ki-10.
