The Mitsubishi Ki-46, also known as the “Dinah”, was a twin-engine reconnaissance aircraft developed by Mitsubishi Heavy Industries for the Imperial Japanese Army Air Force during World War II. It was designed to carry out long-range reconnaissance missions over enemy territory, and was one of the fastest reconnaissance aircraft of the war.

The Ki-46 had a streamlined, low-wing design with a twin-engine configuration and retractable landing gear. It was armed with two 12.7mm machine guns and could carry up to 800 kg (1,764 lbs) of bombs or cameras for reconnaissance missions.

The Ki-46 was used extensively throughout the war, including in operations in China, the Philippines, and the Pacific theater. It was known for its speed and maneuverability, and was often used to outrun and outmaneuver enemy fighters.

In addition to its reconnaissance role, the Ki-46 was also used as a bomber and interceptor, and was equipped with a radar system in later models to improve its night-fighting capabilities.

Despite its success, the Ki-46 was eventually overshadowed by newer, more advanced reconnaissance aircraft such as the Nakajima Ki-43 Oscar and the Kawasaki Ki-45 Toryu. Production of the Ki-46 ceased in 1945, and today, no Ki-46s survive, although some scale models and replicas have been built by aviation enthusiasts.
