Mitsubishi Ki-46 "Dinah"

Mitsubishi · Japan · first flew 1939 · fighter

The Mitsubishi Ki-46 (Allied reporting name 'Dinah') was a Japanese Army twin-engine high-speed reconnaissance aircraft renowned for its outstanding aerodynamic refinement and speed. Late-war variants were converted to interceptors to combat high-flying B-29 raids.

WEFT is AircraftIQ's four-point recognition method — how it works.

Spot it by:

The extremely clean aerodynamic design with a slim fuselage, near-flush engine nacelles, and a large seamlessly blended canopy make the Ki-46 instantly recognisable; no other Japanese aircraft of the era approached its level of aerodynamic refinement.

History

First flying in November 1939, the Ki-46 was virtually untouchable by Allied fighters when it entered service in 1941 due to its high speed. As Allied aircraft improved, the Ki-46-III introduced more powerful engines and remained competitive; the Ki-46-IIIKai interceptor added a 37 mm oblique-firing cannon for attacking bomber formations.

Variants

The Ki-46-I through III series progressively improved speed with larger engines; the Ki-46-III Kai interceptor and Ki-46-IIIb with nose armament were late-war adaptations.

Where you'll see it

Served with the Imperial Japanese Army Air Force across all theatres from China to the Pacific; one of the few Japanese types that remained operationally useful throughout the war.
