Manufacturer: Mitsubishi
First flight: mid-1939

Number built: 2385

The Mitsubishi Ki-51 (Army designation "Type 99 Assault Plane". Allied nickname "Sonia") was a light bomber/dive bomber in service with the Imperial Japanese Army during World War II. It first flew in mid-1939. Initially deployed against Chinese forces, it proved to be too slow to hold up against the fighter aircraft of the other Allied powers. However, it performed a useful ground-attack role in the China-Burma-India theatre, notably from airfields too rough for many other aircraft. As the war drew to a close, they began to be used in kamikaze attacks. Total production was around 2,385 units.

Charles Lindbergh, flying a P-38 Lightning shot down a Ki-51 after a vigorous dogfight in which the much slower Ki-51 utilized its low speed maneuverability and made a fight of it.

Imperial Japanese Army Air Force


In 1945, Indonesian People's Security Force (IPSF) (Indonesian pro-independence guerrillas) captured a small number of aircraft at numerous Japanese air bases, including Bugis Air Base in Malang (repatriated 18 September 1945). Most aircraft were destroyed in military conflicts between the Netherlands and the newly proclaimed-Republic of Indonesia during the Indonesian National Revolution of 1945-1949.


Communist Chinese (captured): The last 4 Ki-51s retired in 1953.


The only surviving Ki-51 is on display on Adisucipto International Airport.
