The Mitsubishi J4M1 was discovered in a captured document, receiving the allied code name ‘Luke’. Although featuring in a December 1944 recognition manual, the prototype was never completed.

Mitsubishi B-97 Darai Doris
Widely described early in the war, and included in the first allied code list, the Darai medium bomber, or anything like it, was never produced or imported by Japan. It does look like the American Bennet BTC-1 described in a 1940 Japanese magazine.
Mitsubishi Shinten / Ha-6
The Mitsubishi Shinten (震天) was a two-row, 14-cylinder air-cooled radial engine built by the Mitsubishi Aircraft Company for the Imperial Japanese Army Air Service (IJAAS) and the Imperial Japanese Navy Air Service (IJNAS). The company model designation was A6(7) while it was an experimental engine project. Once accepted, it was known as the “Shinten” MK1 by IJNAS, and Ha-6 by the IJAAS.
A development of the Mitsubishi Kinsei engine, the stroke of the Kinsei was increased from 150 mm (5.91 in) to 160 mm (6.30 in) on the Shinten model 11 and to 170 mm (6.69 in) on the Shinten model 21 and 21Kai designs.
Lengthening the stroke increased the displacement from the Kinsei’s 32.3 L (1,970 cu in) to 36.1 L (2,200 cu in) for the Shintin model 11. The increased displacement raised the horsepower from 1,070 hp (1,080 PS) to 1,200 hp (1,200 PS) at take-off power.
Initially Ha-6 Shintens were to be installed on Mitsubishi Ki-21 bomber aircraft, but it was decided to use a competing engine, the Nakajima Ha-5 instead. Furthermore Mitsubishi was ordered to produce Nakajima’s engine at its factory under license. So only 113 Shinten engines were made and they were installed on only few types of aircraft.
In order to beat the rival and also to develop a more powerful engine for the new Navy Attack Bomber that became famous Mitsubishi G6M Betty, Mitsubishi Shinten was developed into the Mitsubishi Kasei by increasing the bore from 140 mm (5.51 in) to 150 mm (5.91 in) which in turn brought the displacement to 42 L (2,600 cu in) and increased power to 1,500 hp (1,500 PS).

The Ki-167 was a redesigned Ki-67 bomber intended for kamikaze attacks. First combat use was on April 17, 1945.

Mitsubishi Ki-109
Derived from the Ki-67 Hiryu bomber as a heavy interceptor, the Ki-109 was originally conceived in two versions, the Ki-l09Ko mounting two obliquely-firing 37-mm cannon and the Ki-l09 Otsu equipped with radar and a 15.75-in (40-cm) searchlight, the intention being that the two aircraft would work as a team. Soon thereafter the Ki-109 project was redefined as a bomber interceptor mounting a 75-mm Type 88 cannon with which it could attack its quarry while remaining beyond the range of opposing defensive armament. Converted from a Ki-67 airframe and retaining the dorsal, lateral and tail gun positions of the bomber, and the Mitsubishi Ha-104 engines each rated at 1,900 hp for take-off, the first Ki-109 prototype was completed in August 1944. The second prototype was powered by Ha-104Ru engines with Ru-3 turbosuperchargers, and it was intended that these would be installed in the final 22 aircraft of an initial batch of 42 Ki¬109s. The first series Ki-109 dispensed with the dorsal and lateral gun positions, retaining only the tail position which mounted a single 12,7-mm machine gun, primary armament being the single 75-mm cannon with 15 shells individually loaded by the co-pilot. In the event, production difficulties with the Ru-3 turbosupercharger prevented its application to any series Ki-109s, and only 20 production aircraft were completed, these having standard Ha-104 engines.

Mitsubishi Ki-83
Intended to meet a requirement formulated in 1943 for an advanced two-seat long-range escort fighter. the Ki-83 was designed by a team headed by Totnio Kubo, who had previously been responsible for the Ki-46.
Aerodynamically exceptionally clean and powered by two turbo-supercharged Mitsubishi Ha-211ru 18-cylinder radials, the Ki-83 possessed an armament of two 20-mm and two 30-mm cannon.
The first of four prototypes was flown on 18 November 1944, demon¬strating spectacular performance and remarkable maneuverability for its size – a 2,200-ft (670-rn) diameter loop being executed at 403 mph (648 km/h) at 9,500 ft (2900 m) within 31 sec. However, definitive plans for the series manufac¬ture of the Ki-83 were still being finalised when hostilities terminated.

Mitsubishi Ki-67 Hiryu
To take the place of the Mitsubishi Ki-21 ‘Sally’ and the Nakajima Ki-49 ‘Helen’, the Air Office (Koku Hombu) issued specifications for a new bomber to the Mitsubishi concern in November 1940. The work was led by Chief Engineer Ozawa on an aircraft based on the beautiful Japanese lines and powered by the new generation of Ha-100 double-row 18- cylinder radial engines.
Three prototypes of the Ki-67-I were completed between December 1942 and March 1943, the first making its initial flight on 27 December 1942. The Ki-67-I proved to be fast (though not as fast as originally specified), and extremely manoeuvrable with loops and barrel-rolls being carried out with ease in an unloaded configuration.
Although adopted for service as the Army Type 4 Heavy Bomber, such was the promise of the Ki-67-I that even the Imperial Japanese Navy was impressed, and made early representations to Mitsubishi. On 5 January 1943 Mitsubishi received an order to convert 100 Ki-49s as torpedo-bombers, with internal racks capable of handling the standard 450mm Navy Type 91 Model II aerial torpedo. These saw service with the 762nd Kokutai (air group) from the autumn of 1944 onwards. The Ki-67- I was issued in small numbers to the 7th, 14th, 16th, 61st, 62nd, 74th, 98th and 110th Hikosentais (air regiments) and saw limited action over China, Biak and Sansapor in north western New Guinea, and Sumatra in the summer of 1944.
Comparitively few Ki.67-1a were completed before being superceded by the Ki.677-1b, which continued in production to the end of the war.
Three other manufacturers, Kawasaki, Nippon and Rikugun, were in the production team, but only completed just over 100 aircraft between them.
The type was recognized as such for the first time by the Allies in October 1944, code named ‘Peggy”, during the US 3rd Fleet’s attacks on Formosa and the Ryukyus where the Hiryu served in the 8th Hikoshidan (air division) based on Formosa under navy control. Thereafter Ki-67-Is were encountered over the Philippines, off Iwo Jima, in the strikes on the US 20th Air Force’s bases on Saipan and Tinian, and in the Okinawa campaign where it was used as a suicide aircraft.
For suicide missions the JAAF used modified Peggys known as the Ki-61-I KAI with armament removed and a solid nose packed with explosive. Only two of the more powerful Ki-67-II variant were made, production of army and navy Ki-67-Is amounting to 696.

Mitsubishi MC-20 / Ki-57 / L4M1
With interest shown by Japan Air Lines for a civil version of the Mitsubishi Ki-21 bomber, the company built a Mitsubishi Ki-57 prototype with the civil designation MC 20, which was flown in August 1940.
Essentially, the Ki 57 (Topsy to the Allies) was a low wing version of the Ki 21 I bomber, except for a redesigned fuselage which accommodated a crew of two and up to 11 passengers. The powerplant consisted of two 950 hp Nakajima Ha 5 Kai 14 cylinder radials. The main wheels retracted into the engines nacelles.
Following satisfactory testing the type was ordered into production in 1940 for civil and military use under the designations MC-20-1 and Army Type 100 Transport Model 1 respectively (Mitsubishi Ki-57-I), 100 series aircraft being built.
After 101 of these had been built, Mitsubishi in 1942 replaced this version on the production line with the Ki 57 II Army Type 100 Transport Model 2 /MC 20 II, generally similar but with 1080 hp Mitsubishi Ha 102 radials. They continued in production until January 1945, by which time 406 of this improved model had been completed.
A small number of Ki-57-IIs transferred for use by the Japanese navy were redesignated L4M1 or Navy Type 0 Transport Model 11, and all of these versions had the Allied codename ‘Topsy’.
The Ki 57 featured most notably in the paratroop attack on the airfield at Palembang and neighbouring oil refineries in February 1942.

Mitsubishi Ki-51 / Tachikawa Ki-71 / Watanabe Ki-51
To meet an Imperial Japanese Army specification of December 1937 for a two seat ground-attack aircraft, which it was suggested could be a development of the Ki-30 light bomber, Mitsubishi produced two prototypes under the designation Mitsubishi Ki-51.
The Ki 51 was a cantilever low wing monoplane, with a ‘trousered’ and spatted non retractable main landing gear and a fixed tail wheel. The powerplant for both prototype and production aircraft was a single 940 hp Mitsubishi Ha 26 II 14 cylinder air cooled radial engine, driving a three blade variable pitch metal propeller. The greenhouse canopy was shorter than that on the Ki 30, bringing the two man crew closer together, and a degree of armour protection was provided for the occupants and the engine. The Ki 51 differed from the Ki 30 in having no internal bomb bay, the normal 200-kg (440 lb) weapon load being carried externally. Overall construction was of metal except for the control surfaces, which were fabric covered.
Two prototypes, designated Ki 51, were completed in June and August 1939, followed immediately by a pre series batch of 11 more, all completed by the end of that year. They differed from the prototypes by incorporating a number of modifications, including the introduction of fixed leading-edge slots to improve slow-speed handling and armour plate beneath the engine and crew positions.
After a virtually problem free flight test programme, and only a few minor modifica¬tions, the Ki 51 entered production in January 1940 as the Army Type 99 Assault Aircraft. From then until March 1944 Mit¬subishi’s Nagoya factory manufactured a total of 1459. Four months later a second production line was established by Tachikawa, which had completed a further 913 by July 1945. Standard armament at first consisted of three 7.7 mm (0.303 in) Type 89 machine guns, one in each wing and one in a movable mounting in the rear cockpit. On later aircraft, the wing mounted pair were exchanged for Type 1 guns of 12.7 mm (0.5¬in) calibre, and the aircraft’s range was increased by installing a 68 litre (15 Imp gal) fuel tank in each wing leading edge. The Ki¬-51 served with at least eight Sentais (groups) and a dozen or more independent squadrons of the Japanese army air force, from 1940 until the end of the Second World War. It established a reputation for being reliable and capable of surviving considerable battle dam¬age, which made it popular with its crews. It was given the Pacific codename Sonia by the Allies. Adapted, inevitably, for the kamikaze role towards the end of the war, it was flown as a single seater, carrying a 250 kg (550 lb) bomb beneath the fuselage.
In addition to the standard production aircraft, there were attempts to develop dedicated reconnaissance versions, initially by the conversion of one Ki-51 service trials aircraft which had the rear cockpit redesigned to accommodate reconnaissance cameras. Test and evaluation of this aircraft, redesignated Ki-51a, brought a realization that the standard Ki-51 could be modified to have provisions for the installation of reconnaissance cameras, and this change was made on the production line.
Three prototypes were completed at Tachikawa of the Ki 71 (codenamed Edna), an improved, retractable gear version with a 1500 hp / 1119kW Mitsubishi Ha-112-11 engine and two 20mm wing cannon, but no production orders for this type were placed.
Allocated the Allied codename ‘Sonia’, the Ki-51 was used initially in operations against China, and was deployed against the Allies until the end of the Pacific war. In more intensely contested areas the fairly slow Ki-51s were easy prey for Allied fighters, but in secondary theatres, where an ability to operate from rough and short fields was valuable, these aircraft gave essential close support in countless operations. In the closing stages of the war they were used in kamikaze attacks.

Mitsubishi Ki-46
The Mitsubishi Ki-46 was designed to meet an Imperial Japanese Army requirement of 1937 for a higher performance reconnaissance aircraft to supersede the Ki-15. The specification called for an endurance of six hours at 250mph (400 km/h), between 13,500 and 20,000 ft (4,000 and 6,000m) and a maximum speed of 375mph (604km/h) at 13,500 ft (4,000m). The man responsible for the design was Tomio Kubo, who was assisted by the Aeronautical Research Institute of the University of Tokyo.
Work on the design started in December 1937, as a cantilever low-wing monoplane with retractable tailwheel landing gear, powered by two 900 hp / 671kW Mitsubishi Ha-26 radial engines. Kubo selected a small diameter fuselage with the main fuel tank located between pilot and observer, and thin section wings.
The two-seat Ki-46 prototype was flown (by Major Fujita) for the first time in late November 1939 from Kagamigahara in Gifu Prefecture, north of Nagoya. Early testing showed that maximum speed of the Ki-46 was some 10% below specification (540 km/h / 335 mph) at 4000 m / 13,000 ft), but as its speed and overall performance was better than in-service army and navy aircraft the type was ordered into production as the Army Type 100 Command Reconnaissance Plane Model 1 (Ki-46-l), later allocated the Allied codename ‘Dinah’.
The entire Model 1 production (34 were built between 1939 40) plus the prototype were delivered to the Shimshizu flying school and to a special experimental reconnaissance unit. The aircraft was known as the Shintei in Japanese service, but was soon better known to the allies under its simplified identification name, the Dinah.
The Ki-46-1 series was soon replaced by the Ki-46II, which utilised the more powerful Ha102 engines, fitted with two-speed supercharger and rated at 1,080 hp each. The increase in available horsepower meant that the performance of the II improved, maximum speed rose to 375 mph (604 kph) at 19,030 ft (5,800 m). The transition to the new series was not without its problems, vapour locks were experienced and it was only after extensive research that the cause was found. Relocation of the fuel lines around the engines and a change from 87 to 92-octane fuel seemed to cure it. Poor aileron and rudder response, overheating of the oil and an unreliable oxygen system that to crew anoxia, were all problems which had to be overcome. Another problem involved the undercarriage, due to the aircraft’s high rate of sink it was quite a common occurrence for the undercarriage to collapse on landing. Although stronger auxiliary rear struts were fitted this problem was to persist throughout the Ki-46’s operational life.
The first Model 2 appeared in March 1941, the airframe was identical with the Model 1 and production soon gathered momentum. The Type 100 was delivered from July 1941 onwards to the 18th, 50th, 51st, 70th, 74th, 76th and 81st Independent Chutais (squadrons) based in China and Manchuria. Chinese air opposition was poor and the escape capability of Ki 46 such that the sole defensive armament, a single 7.7 mrn (0.303 in) Type 89 machine gun on a flexible mounting operated by the observer, was seldom used in action.
During October 1941 Ki 46s based in French Indo China reconnoitred the Japanese army’s planned landing zones for the December invasion of Malaya. From December 1941 onwards, Ki 46s were deployed in small detachments in every army zone of operations, enjoying considerable success and remaining virtually unmolested for the first year of fighting. Such was the esteem in which the type was held that the Luftwaffe attempted to arrange licence production, and the army’s greatest rival, the navy, managed to acquire a few for its own use.
As the losses suffered by the Ki-46II units increased the Koku Hombu, in May 1942, they instructed Mitsubishi to upgrade the Ki-46-II. This was achieved with the installation of two Mitsubishi Ha 112-II engines, rated at 1,500hp each, this boosted the top speed to 404 mph (650 km/h) and increased the range to 2,485 miles and endurance by an hour. The new design was designated the Ki-46-III and with it came a whole new shape. Gone was the stepped canopy of the II series and in came a completely aerodynamic nose, with the canopy glazing extending right to the front of the aircraft in a smooth slope. The reason for the re-designed front was a simple, not just one born of aerodynamic necessity. The new engines required more fuel and the thin wing adopted in the original design allowed no room for fuel cells, it was therefore decided to fit an additional tank in front of the pilot. This tank held 52 Imp Gal (220 litres), provision was also made for the fitment of a ventral drop tank, holding 101.2 Imp Gal (460 litres). The undercarriage was beefed up and the provision for a single flexible machine gun in the rear cockpit was dispensed with.
As supply of the III series increased, some II’s were converted into three seat radio navigation trainers, designated the Ki46-II Kai, they operated with the Shimoshizu Rikugun Hikogakuko (Shimoshizu Army Flying School).
609 Ki-46-III were built, a small number being converted later as Ki-46-III KAI fighter interceptors and Ki-46IIIb ground-attack aircraft.
The Ki-46-II and the Ki46-IIKai (Kai=KAIZO “Modified”) trainer were the main production version of the Ki-46 design, with 1,093 being built.
In June 1943, the Rikugun Kokugijutsu Kenkyujo, or Army Aerotechnical Research Institute, began to study the adaptation of the Ki-46-III reconnaissance aircraft for the high-altitude interceptor fighter role. Development was actively pursued from May 1944 as the Ki-46-III KAI, or Army Type 100 Air Defence Fighter, and the Army Air Arsenal at Tachikawa instituted a conversion programme.
The nose was redesigned a new stepped cockpit canopy, and to accommodate two 20-mm Ho-5 cannon and the top centre fuselage fuel tank was removed to provide space for a Ho-203 37-mm cannon firing forward and upward at an angle of 30 deg. The two Mitsubishi Ha-112-lI engines rated at 1,500 hp for take-off were retained, and the first Ki-46-IIl KAI two-seat interceptor was completed by Tachikawa Dai-lchi Rikugun Kokushok and flown in October 1944, deliveries to operational units commencing during November. Operational results were disappointing owing to the poor climb rate of this type, but the conversion programme was continued at Tachikawa until March 1945, a substantial number being delivered. One unit was the 16th Dokuritsu, Hikotai, which operated in the latter months of the war.
With more powerful 1500-hp Mitsubishi Ha 112 11 engines and increased range, thanks to enlarged internal tankage and the introduction of a 460 litre (101 Imp gal) ventral drop tank, Model 3 showed a 26 km/h (16 mph) improvement in top speed over Model 2 and achieved a maximum range of 4000 km (2500 miles). External appearance was greatly changed by the new canopy over the pilot’s cockpit, without the conventional step between the nose and top of fuselage which had characterized the earlier versions. Performance was so good that defensive armament was dispensed with. Production at Mitsubishi’s Nagoya factory was hindered by earthquake damage in December 1944, and a further 100 of the type were built at Toyama.
Late production Ki-46-III’s coming from both plants were fitted with individual exhaust stacks providing some thrust augmentation, which increased their speed and range slightly.
Operational trainer modifications of the Model 2 serving with the specialist Shimshizu flying school had a third, stepped up cockpit fitted immediately behind the pilot’s seat.
A few Ki 46 IIIb assault aircraft, devel¬oped from the intercepter, were built, and four Ki 46 IV high altitude prototypes during 1943 & 44, pow¬ered by 1,100 hp / 1119kW (at 33,465 ft / 10,200 m) Mitsubishi Ha 112 Ru supercharged engines, were tested from February 1944 onwards. Difficulties with the superchargers prevented production of the proposed reconnaissance and fighter versions. Total production of the Ki 46 in all variants was 1742 of which 902 were the III series, all built by Mitsubishi. All were initially manufactured by Mitsubishi at their Nagoya plant, but when this was damaged by an earthquake in December 1944, as well as being pounded by the B-29’s of the US Air Force, production was transferred to their new plant at Toyama. Only about one hundred aircraft came out of this plant by wars end.
