The Mitsubishi A7MReppū was designed as the successor to the Imperial Japanese Navy's A6M Zero, with development beginning in 1942. Performance objectives were to achieve superior speed, climb, diving, and armament over the Zero, as well as better maneuverability – all parameters that were ultimately achieved towards the end of its development in 1945. However, limitations on Japanese industry towards the end of the war prevented the A7M from ever entering mass production or being deployed for active duty, and it never saw active service. Its Allied reporting name was "Sam".
The Nakajima Ki-43 Hayabusa, formal Japanese designation Army Type 1 Fighter is a single-engine land-based tactical fighter used by the Imperial Japanese Army Air Service in World War II.
The Mitsubishi J2M Raiden is a single-engined land-based fighter aircraft used by the Imperial Japanese Navy Air Service in World War II. The Allied reporting name was "Jack".
The Mitsubishi Ki-46 was a twin-engine reconnaissance aircraft that was used by the Imperial Japanese Army in World War II. Its Army Shiki designation was Type 100 Command Reconnaissance Aircraft (一〇〇式司令部偵察機); the Allied brevity code name was "Dinah".
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-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-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-70 "Clara" was a high speed photo reconnaissance aircraft that was tested for the Japanese Air Force in prototype form but never entered production. The Ki-70 was the intended successor to the Mitsubishi Ki-46 but was difficult to handle and was slower than the Mitsubishi Ki-46. The Ki-70 was first flown in 1943 but was found unsatisfactory and the program was terminated. Three aircraft were built.
The Tachikawa Ki-17 was a basic training aircraft of the Imperial Japanese Army Air Force built by Tachikawa Aircraft Company Ltd in the 1930s. It was known to the Allies under the nickname of Cedar during World War II.
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-36 was a Japanese army co-operation aircraft of World War II. It was a two-seat, low-wing monoplane with a single piston engine and fixed, tailwheel-type undercarriage.
The Nakajima Ki-87 was a Japanese prototype 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 Tachikawa Ki-74 was a Japanese experimental long-range reconnaissance bomber of World War II. A twin-engine, mid-wing monoplane, it was developed for the Imperial Japanese Army Air Service but never deployed in combat. The Ki-74 was designed for high altitude operation with a pressurized cabin for its crew.
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-30 was a Japanese light bomber of World War II. It was a single-engine, mid-wing, cantilever monoplane of stressed-skin construction with a fixed tailwheel undercarriage and a long transparent cockpit canopy. The type had significance in being the first Japanese aircraft to be powered by a modern two-row radial engine. During the war, it was known by the Allies by the name Ann. It was mistakenly identified by the British as the Mitsubishi Army 97 Ann.
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 Mitsubishi Ki-2 was a light bomber built by Mitsubishi for the Imperial Japanese Army Air Service (IJAAS) in the 1930s. Its Allied nickname was "Louise". Despite its antiquated appearance, the Ki-2 was successfully used in Manchukuo and in North China during the early stages of the Second Sino-Japanese War, in areas where danger from enemy fighter aircraft was minimal. It was later used in a training role.
The Mitsubishi Ki-18 was an unsuccessful and unsolicited attempt by Mitsubishi to meet a 1934 requirement issued by the Japanese Army for a modern single-seat monoplane fighter suitable to the needs of the Imperial Japanese Army Air Force. During this competition, Nakajima entered the Nakajima Ki-11, and Kawasaki entered the more maneuverable Kawasaki Ki-10 biplane. The competition was won by Kawasaki, but the new fighter was not accepted by the IJAAF with much enthusiasm.
The Mitsubishi J4M Senden or Navy Experimental 17-Shi Otsu B Type Interceptor Fighter Senden, Allied reporting name Luke, was a Japanese World War II fighter aircraft proposed by Mitsubishi Heavy Industries for use by the Imperial Japanese Navy. The J4M project did not proceed beyond the design stage.
The Mansyū Ki-98,, was a Japanese ground-attack aircraft proposed by Mansyū during World War II for use by the Imperial Japanese Army Air Force. The still unassembled components of the first prototype were deliberately destroyed before Japan surrendered.
