The Nakajima Ki-116 was a late-World War II aircraft developed for the Imperial Japanese Army Air Force. It was essentially a Ki-84 Hayate with the Nakajima Ha-45 engine replaced with a Mitsubishi Ha-112. The design was handled by Mansyū Aircraft in Manchukuo, and thus it is often designated Mansyū Ki-116.
The Kawasaki Ki-61 Hien is a Japanese World War II fighter aircraft. Used by the Imperial Japanese Army Air Service, it was designated the "Army Type 3 Fighter" (三式戦闘機). Allied intelligence initially believed Ki-61s were Messerschmitt Bf 109s and later an Italian Macchi C.202, which led to the Allied reporting name of "Tony", assigned by the United States War Department. The design originated as a variant of the Kawasaki Ki-60, which never entered production. The Ki-61 became the only mass-produced Japanese fighter of the war to use a liquid-cooled inline V engine. Over 3,000 Ki-61s were produced. Initial prototypes saw action over Yokohama during the Doolittle Raid on 18 April 1942, and continued to fly combat missions throughout the war.
The Kawasaki Ki-100 (キ100) is a single-seat single-engine monoplane fighter aircraft used by the Imperial Japanese Army Air Service during World War II. The Japanese Army designation was "Type 5 Fighter". It was not assigned an Allied code name.
The Mitsubishi Ki-67Hiryū was a twin-engine bomber produced by Mitsubishi Aircraft Company and used by the Imperial Japanese Army Air Service and Imperial Japanese Navy Air Service in World War II. While its original official designation was "Army Type 4 Heavy Bomber", in all of its key parameters, the Ki-67 was similar to the contemporaneous medium bombers of other countries. Japanese Navy variants included the P2M and Q2M.
The Nakajima Ki-84 Hayate is a single-seat fighter flown by the Imperial Japanese Army Air Service in the last two years of World War II. The Allied reporting name was "Frank"; the Japanese Army designation was Army Type 4 Fighter. The Ki-84 is generally considered the best Japanese fighter to operate in large numbers during the conflict. The aircraft boasted high speed and excellent maneuverability with an armament that gave it formidable firepower. The Ki-84's performance matched that of any single-engine Allied fighter it faced, and its operational ceiling enabled it to intercept high-flying B-29 Superfortress bombers. Pilots and crews in the field learned to take care with the plane's high-maintenance Nakajima Homare engine and a landing gear prone to buckling. The difficulties of Japan's situation late in the war took a toll on the aircraft's field performance as manufacturing defects multiplied, good quality fuel proved difficult to procure, and experienced pilots grew scarce. Nevertheless, a well-maintained Ki-84 was Japan's fastest fighter. A total of 3,514 aircraft were built.
The Kawasaki Ki-45 Toryu was a two-seat, twin-engine heavy fighter used by the Imperial Japanese Army in World War II. The army gave it the designation "Type 2 Two-Seat Fighter"; the Allied reporting name was "Nick". Originally serving as a long-range escort-fighter, the design — as with most heavy fighters of the period — fell prey to smaller, lighter, more agile single-engine fighters. As such, the Ki-45 instead served as a day and nighttime interceptor and strike fighter.
The Kawasaki Ki-10 was the last biplane fighter used by the Imperial Japanese Army, entering service in 1935. Built by Kawasaki Kōkūki Kōgyō K.K. for the Imperial Japanese Army, it saw combat service in Manchukuo and in North China during the early stages of the Second Sino-Japanese War. Its reporting name given by the Allies was "Perry".
The Nakajima Ki-27 was the main fighter aircraft used by the Imperial Japanese Army Air Service up until 1940. Its Allied nickname was "Nate", although it was called "Abdul" in the "China Burma India" (CBI) theater by many post war sources; Allied Intelligence had reserved that name for the nonexistent Mitsubishi Navy Type 97 fighter, expected to be the successor to the carrier-borne Type 96 with retractable landing gear and an enclosed cockpit.
The Kawasaki Ki-60 was an experimental Japanese pre-World War II fighter aircraft that used a license-built (Kawasaki) DB 601 liquid-cooled engine. This was at that time an unusual choice because the majority of Japanese aircraft at that time used air-cooled radial engines.
The Mitsubishi Ki-51 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 theater, notably from airfields too rough for many other aircraft. As the war drew to a close, the Japanese began using them in kamikaze attacks. Total production was around 2,385 units.
The Kawasaki Ki-102 or Type 4 Attack Plane was a Japanese warplane of World War II. It was a twin-engine, two-seat, long-range heavy fighter developed to replace the Ki-45 Toryu. Three versions were planned: the Ki-102 Kō day fighter, Ki-102 Otsu ground-attack and Ki-102 Hei night fighter. This aircraft's Allied reporting name was "Randy".
The Tachikawa Ki-94 was a single-seat fighter-Interceptor aircraft project undertaken by the Tachikawa Aircraft Company and to be operated by the Imperial Japanese Army. The project refers to two aircraft designs: the Ki-94-I and the Ki-94-II, both of which did not advance beyond the mock-up and prototype stage respectively.
The Tachikawa Ki-55 was a Japanese advanced trainer.
The Kawasaki Ki-96 was a Japanese single seat, twin-engine heavy fighter of World War II. It was intended to replace the Kawasaki Ki-45s of the Imperial Japanese Army Air Service. However, it was not adopted and only three prototypes were built.
The Nakajima Ki-87 was a Japanese high-altitude fighter-interceptor of World War II. It was a single seat, exhaust-driven turbo-supercharged engined, low-wing monoplane with a conventional undercarriage.
The Nakajima Ki-49Donryu was a twin-engine Japanese World War II heavy bomber. It was designed to carry out daylight bombing missions, without the protection of escort fighters. Consequently, while its official designation, Army Type 100 Heavy Bomber, was accurate in regard to its formidable defensive armament and armor, these features restricted the Ki-49 to payloads comparable to those of lighter medium bombers – the initial production variant could carry only 1,000 kg (2,200 lb) of bombs.
The Mitsubishi Ki-83 (キ83) was a Japanese experimental long range heavy fighter designed near the end of World War II. It did not reach production status.
The Kawasaki Ki-28, World War II Allied reporting name "Bob", was an experimental fighter aircraft designed for the Imperial Japanese Army and meant as a replacement for the Kawasaki Ki-10. It flew in 1936, but was never produced for actual use as the Army chose the Nakajima Ki-27.
The Rikugun Ki-93 was a prototype Japanese twin-engined fighter aircraft of the Second World War. Designed by the Army Aerotechnical Research Institute, to be a heavy fighter armed with large calibre cannon to serve in the anti-shipping or bomber destroyer roles, only one example of the Ki-93 was completed; this was damaged on its maiden flight, and destroyed by American bombing before it could be flown again.
The Kawasaki Ha40, also known as the Army Type 2 1,100 hp Liquid Cooled In-line and Ha-60, was a license-built Daimler-Benz DB 601Aa 12-cylinder liquid-cooled inverted-vee aircraft engine. The Imperial Japanese Army Air Service (IJAAS) selected the engine to power its Kawasaki Ki-61 fighter.
