Yokosuka K5Y Type 93 Intermediate Trainer (Willow)

Here are some images of Entex (Nitto molds) 1/32 scale Yokosuka K5Y Type 93 Intermediate Trainer (Willow).

From Wikipedia"
The Yokosuka K5Y was a two-seat unequal-span biplane trainer (Allied reporting name: "Willow") that served in the Imperial Japanese Navy during World War II. Due to its bright orange paint scheme (applied to all Japanese military trainers for visibility), it earned the nickname "aka-tombo", or "red dragonfly", after a type of insect common throughout Japan.
A K5Y of the Kamikaze Special Attack Corps 3rd Ryuko Squadron was credited with sinking the destroyer USS Callaghan on July 29, 1945, the last US warship lost to kamikaze attack during the war.
 The aircraft was based on the Yokosuka Navy Type 91 Intermediate Trainer, but stability problems led to a redesign by Kawanishi in 1933. It entered service in 1934 as Navy Type 93 Intermediate Trainer K5Y1 with fixed tail-skid landing gear, and remained in use throughout the war. Floatplane types K5Y2 and K5Y3 were also produced. After the initial 60 examples by Kawanishi, production was continued by Watanabe (556 aircraft built), Mitsubishi (60), Hitachi (1,393), First Naval Air Technical Arsenal (75), Nakajima (24), Nippon (2,733), and Fuji (896), for a total of 5,770. These aircraft were the mainstay of Imperial Japanese Navy Air Service's flight training, and as intermediate trainers, they were capable of performing demanding aerobatic maneuvers. Two further land-based versions, the K5Y4 with a 358 kW (480 hp) Amakaze 21A engine and the K5Y5 with a 384 kW (515 hp) Amakaze 15, were projected but never built.
 Indonesian People's Security Force (the precursor of Indonesian Air Force) operated derelict aircraft against Dutch colonial rule. On July 29 1947, Indonesia using 2 units of Yokosuka K5Y (Called "Cureng/Churen" by Indonesian fighters) with one "Guntei Bomber" (Mitsubishi Ki-51 from Maguwo Air Force Base, Yogyakarta for bombing Dutch strategic positions in Ambarawa, Salatiga and Semarang. On its original plan, Nakajima Ki-43 "Hayabusa" also planned to be involved too in this operation, but cancelled as the aircraft suffered technical difficulties. It is currently on display at Jakarta.

Nakajima A6M2-N Rufe

Here are some images of Trumpeter's 1/24 scale Nakajima A6M2-N Rufe.
Back in the day the very idea of a 1/24 scale Rufe would have been very unlikely.
But thanks to Trumpeter there are now not only a Rufe, but a Spitfire float plane and a Spitfire Mk VI  various Mk V's and now coming soon a Junkers 87 A. Back then these aircraft in model kit form would have either only been found in garage kit form or a limited release special edition, let alone in 1/24 scale. The Rufe itself was a straight forward build with no real issues. An impressive display on any shelf.

From Wikipedia"
The Nakajima A6M2-N (Navy Type 2 Interceptor/Fighter-Bomber) was a single-crew floatplane based on the Mitsubishi A6M Zero Model 11. The Allied reporting name for the aircraft was Rufe.
 The A6M2-N floatplane was developed from the Mitsubishi A6M Type 0, mainly to support amphibious operations and defend remote bases. It was based on the A6M-2 Model 11 fuselage, with a modified tail and added floats. A total of 327 were built, including the original prototype.

The aircraft was deployed in 1942, referred to as the "Suisen 2" ("Hydro fighter type 2"), and was only utilized in defensive actions in the Aleutians and Solomon Islands operations. Such seaplanes were effective in harassing American PT boats at night. They could also drop flares to illuminate the PTs which were vulnerable to destroyer gunfire, and depended on cover of darkness.

A6M2-Ns at Attu, Alaska

The seaplane also served as an interceptor for protecting fueling depots in Balikpapan and Avon Bases (Dutch East Indies) and reinforced the Shumushu base (North Kuriles) in the same period. Such fighters served aboard seaplane carriers Kamikawa Maru in the Solomons and Kuriles areas and aboard Japanese raiders Hokoku Maru and Aikoku Maru in Indian Ocean raids. In the Aleutian Campaign this fighter engaged with RCAF Curtiss P-40, Lockheed P-38 Lightning fighters and Boeing B-17 Flying Fortress bombers.^{[citation needed]} The aircraft was used for interceptor, fighter-bomber, and short reconnaissance support for amphibious landings, among other uses.
Later in the conflict the Otsu Air Group utilized the A6M2-N as an interceptor alongside Kawanishi N1K1 Kyofu ("Rex") aircraft based in Biwa lake in the Honshū area.
The last A6M2-N in military service was a single example recovered by the French forces in Indochina after the end of World War II. It crashed shortly after being overhauled.
The large float and wing pontoons of the A6M2-N degraded its performance by only about 20%. However, this caused the A6M2-N to be unable to confront the first generation of Allied fighters

Yokosuka MXY-7 Ohka Model 11

Here are some images of HpH Models 1/32 scale Yokosuka MXY-7 Ohka Model 11.
In my opinion this is the saddest aircraft ever created.

From Wikipedia"
The Yokosuka MXY-7 Ohka (櫻花^? Ōka, "cherry blossom"; 桜花 in modern orthography) was a purpose-built, rocket powered human-guided anti-shipping kamikaze attack aircraft^[1] employed by Japan towards the end of World War II. United States sailors gave the aircraft the nickname Baka (ばか^?, "fool" or "idiot")).

The MXY-7 Navy Suicide Attacker Ohka was a manned flying bomb that was usually carried underneath a Mitsubishi G4M2e Model 24J "Betty" bomber to within range of its target. On release, the pilot would first glide towards the target and when close enough he would fire the Ohka's three solid-fuel rockets, one at a time or in unison, and fly the missile towards the ship that he intended to destroy.
The design was conceived by Ensign Mitsuo Ohta of the 405th Kōkūtai, aided by students of the Aeronautical Research Institute at the University of Tokyo. Ohta submitted his plans to the Yokosuka research facility. The Imperial Japanese Navy decided the idea had merit and Yokosuka engineers of the Yokosuka Naval Air Technical Arsenal (Dai-Ichi Kaigun Koku Gijitsusho, or in short Kugisho) created formal blueprints for what was to be the MXY7. The only variant which saw service was the Model 11, and it was powered by three Type 4 Mark 1 Model 20 rockets. 155 Ohka Model 11s were built at Yokosuka, and another 600 were built at the Kasumigaura Naval Air Arsenal.
The final approach was difficult for a defender to stop because the aircraft gained high speed (650 km/h (400 mph) in level flight and 930 km/h (580 mph) or even 1,000 km/h (620 mph) in a dive. Later versions were designed to be launched from coastal air bases and caves, and even from submarines equipped with aircraft catapults, although none were actually used in this way. It appears that the operational record of Ohkas includes three ships sunk or damaged beyond repair and three other ships with significant damage. Seven U.S. ships were damaged or sunk by Ohkas throughout the war. The USS Mannert L. Abele was the first Allied ship to be sunk by Ohka aircraft, near Okinawa on 12 April 1945.
The Ohka pilots, members of the Jinrai Butai (Thunder Gods Corps), are honored in Japan at Ohka Park in Kashima City, the Ohka Monument in Kanoya City, the Kamakura Ohka Monument at Kenchō-ji Kamakura, and the Yasukuni Shrine in Tokyo.

Thermojet powered Model 22, note the jet intake

The only operational Ohka was the Model 11. Essentially a 1,200 kg (2,646 lb) bomb with wooden wings, powered by three Type 4 Model 1 Mark 20 solid-fuel rocket motors, the Model 11 achieved great speed, but with limited range. This was problematic, as it required the slow, heavily laden mother aircraft to approach within 37 km (20 nmi; 23 mi) of the target, making them very vulnerable to defending fighters. There was one experimental variant of the Model 11, the Model 21, which had thin steel wings manufactured by Nakajima. It had the engine of the Model 11 and the airframe of the Model 22.
The Ohka K-1 was an unpowered trainer version with water ballast instead of warhead and engines, to provide pilots with handling experience. 45 were built by Dai-Ichi Kaigun Koku Gijitsusho.^[10]
The Model 22 was designed to overcome the short standoff distance problem by using a Campini-type thermojet engine, the Tsu-11. This engine was successfully tested, and 50 Model 22 Ohkas were built at Yokosuka to accept this engine. The Model 22 was to be launched by the more agile Yokosuka P1Y3 Ginga "Frances" bomber, necessitating a shorter wing span and much smaller 600 kg (1,320 lb) warhead. None appears to have been used operationally, and only three of the experimental Tsu-11s engines are known to have been produced.
The Model 33 was a larger version of the Model 22 powered by an Ishikawajima Ne-20 turbojet with an 800 kg (1,760 lb) warhead. The mothership was to be the Nakajima G8N Renzan. Model 33 was cancelled due to the likelihood that the Renzan would not be available.
Other unbuilt planned variants were the Model 43A with folding wings, to be launched from submarines, and the Model 43B, a catapult/rocket assisted version, also with folding wings so that it could be hidden in caves. A trainer version was also under development for this version, the two-seat Model 43 K-1 Kai Wakazakura (Young Cherry), fitted with a single rocket motor. In place of the warhead, a second seat was installed for the student pilot. Two of this version were built.
Finally, the Model 53 would also use the Ne-20 turbojet, but was to be towed like a glider and released near its target.
The Yokosuka MXY7 Ohka was used mostly against U.S. ships invading Okinawa, and if launched from its mothership, could be effective because of its high speed in the dive.^[13] In the first two attempts to transport the Ohkas to Leyte Gulf using aircraft carriers, the carriers Shinano and Unryu were sunk by the U.S. submarines Archerfish and Redfish.
Attacks intensified in April 1945. On 1 April 1945, six "Bettys" attacked the U.S. fleet off Okinawa. At least one made a successful attack; its Ohka was thought to have hit one of the 406 mm (16 in) turrets on the battleship West Virginia, causing moderate damage. Postwar analysis indicated that no hits were recorded and that a near-miss took place. The transports Alpine, Achernar, and Tyrrell were also hit by kamikaze aircraft, but it is unclear whether any of these were Ohkas from the other "Bettys". None of the "Bettys" returned.
The U.S. military quickly realized the danger and concentrated on extending their "defensive rings" outward to intercept the "Betty"/Ohka combination aircraft before the suicide mission could be launched. On 12 April 1945, nine "Bettys" attacked the U.S. fleet off Okinawa. The destroyer Mannert L. Abele was hit, broke in two, and sank, witnessed by LSMR-189 CO James M. Stewart. Jeffers destroyed an Ohka with AA fire 45 m (50 yd) from the ship, but the resulting explosion was still powerful enough to cause extensive damage, forcing Jeffers to withdraw. The destroyer Stanly was attacked by two Ohkas. One struck above the waterline just behind the ship's bow, its charge passing completely through the hull and splashing into the sea, where it detonated underwater, causing little damage to the ship. The other Ohka narrowly missed (its pilot probably killed by anti-aircraft fire) and crashed into the sea, knocking off the Stanly's ensign in the process. One Betty returned. On 14 April 1945, seven "Bettys" attacked the U.S. fleet off Okinawa. None returned. None of the Ohkas appeared to have been launched. Two days later, six "Bettys" attacked the U.S. fleet off Okinawa. Two returned, but no Ohkas had hit their targets. Later, on 28 April 1945, four "Bettys" attacked the U.S. fleet off Okinawa at night. One returned. No hits were recorded.
May 1945 saw another series of attacks. On 4 May 1945, seven "Bettys" attacked the U.S. fleet off Okinawa. One Ohka hit the bridge of a minesweeper, Shea, causing extensive damage and casualties. Gayety was also damaged by an Ohka's near miss. One "Betty" returned. On 11 May 1945, four "Bettys" attacked the U.S. fleet off Okinawa. The destroyer Hugh W. Hadley was hit and suffered extensive damage and flooding. The vessel was judged beyond repair. On 25 May 1945, 11 "Bettys" attacked the fleet off Okinawa. Bad weather forced most of the aircraft to turn back, and none of the others hit targets.
On 22 June 1945, six "Bettys" attacked the fleet. Two returned, but no hits were recorded. Postwar analysis concluded that the Ohka's impact was negligible, since no U.S. Navy capital ships had been hit during the attacks because of the effective defensive tactics that were employed.

Kyushu J7W1 Shinden

Here are some more images of Zoukei-mura's (ZM) 1/32 scale Kyushu J7W1 Shinden in Hypothetical markings.
I would argue that the Shinden would be a serious contender for the worlds most beautiful aircraft ever created.

From Wikipedia"

The Kyūshū J7W1 Shinden (震電, "Magnificent Lightning") fighter was a World War II Japanese propeller-driven aircraft prototype that was built in a canard design. The wings were attached to the tail section and stabilizers were on the front. The propeller was also in the rear, in a pusher configuration.
Developed by the Imperial Japanese Navy (IJN) as a short-range, land-based interceptor, the J7W was a response to B-29 Superfortress raids on the Japanese home islands. For interception missions, the J7W was to be armed with four forward-firing 30 mm cannons in the nose.
The Shinden was expected to be a highly maneuverable interceptor, but only two prototypes were finished before the end of war. Plans were also drawn up for a gas turbine–powered version, but this never even reached the drawing board.
The "J-" designation referred to land-based fighters of the IJN and the "-W-" to Watanabe Tekkōjo, the company that oversaw the initial design; Watanabe changed its name in 1943 to Kyūshū Hikōki K.K.
The idea of a canard-based design originated with Lieutenant Commander Masayoshi Tsuruno, of the technical staff of the IJN in early 1943. Tsuruno believed the design could easily be retrofitted with a turbojet, when suitable engines became available. His ideas were worked out by the First Naval Air Technical Arsenal (Dai-Ichi Kaigun Koku Gijitsusho), which designed three gliders designated Yokosuka MXY6, featuring canards. These were built by Chigasaki Seizo K. K. and one was later fitted with a 22 hp Semi 11 (Ha-90) 4-cylinder air-cooled engine.
The feasibility of the canard design was proven by both the powered and unpowered versions of the MYX6 by the end of 1943, and the Navy were so impressed by the flight testing, they instructed the Kyushu Aircraft Company to design a canard interceptor around Tsuruno's concept. Kyushu was chosen because both its design team and production facilities were relatively unburdened,and Tsuruno was chosen to lead a team from Dai-Ichi Kaigun Koku Gijitsusho to aid Kyushu's design works.
The construction of the first two prototypes started in earnest by June 1944, stress calculations were finished by January 1945, and the first prototype was completed in April 1945. The 2,130 hp Mitsubishi MK9D (Ha-43) radial engine and its supercharger were installed behind the cockpit and drove a six-bladed propeller via an extension shaft. Engine cooling was to be provided by long, narrow, obliquely mounted intakes on the side of the fuselage. It was this configuration that caused cooling problems while running the engine while it was still on the ground. This, together with the unavailability of some equipment parts postponed the first flight of the Shinden.
Even before the first prototype took to the air the Navy had already ordered the J7W1 into production, with quotas of 30 Shinden a month given to Kyushu's Zasshonokuma factory and 120 from Nakajima's Handa plant. It was estimated some 1,086 Shinden could be produced between April 1946 and March 1947.
On 3 August 1945, the prototype first took off, with Tsuruno at the controls, from Itazuke Air Base. Two more short flights were made, a total of 45 minutes airborne, by war's end. Flights were successful, but showed a marked torque pull to starboard (due to the powerful engine), some flutter of the propeller blades, and vibration in the extended drive shaft.

The two prototypes were the only Shinden completed. After the end of the war, one prototype was scrapped; the other J7W1 was claimed by a US Navy Technical Air Intelligence Unit in late 1945, dismantled and shipped to the United States. (Some sources claim that the USN took the first built while others state that it was the second.)
The sole remaining J7W1 was reassembled, but has never been flown in the United States; the USN transferred it to the Smithsonian Institution in 1960. It is currently in storage at the National Air and Space Museum in Washington DC.^[4][10] In 1998 it was reported to be located at Building 7 of the U.S. National Air And Space Museum Garber Facility in Suitland, Maryland.

Nakajima Ki-27Otsu Nate

Here are some images of Special Hobby's 1/32 scale Nakajima Ki-27Otsu Nate.

From Wikipedia"
The Nakajima Ki-27 (九七式戦闘機 Kyūnana-shiki sentōki, or Type 97 Fighter) was the main fighter aircraft used by the Imperial Japanese Army Air Force 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 Type 96 carrier-borne A5M with retractable landing gear and an enclosed cockpit.
In 1935, the Imperial Japanese Army held a competition between Nakajima, Mitsubishi, and Kawasaki to design a low-wing monoplane to replace the Kawasaki Ki-10 (Army Type 95 Fighter) biplane. The new fighter was to have also a better performance than the experimental Mitsubishi Ki-18.^[4]
The results were the Nakajima Ki-27, the Kawasaki Ki-28, and the Mitsubishi Ki-33 (a modification of the Mitsubishi A5M carrier-based fighter). The Nakajima design was based on its earlier Ki-11 monoplane fighter which lost to the Ki-10 in the Type 95 Fighter competition. When the follow-up Nakajima Ki-12 proposal with a liquid-cooled engine and retractable landing gear was deemed too complex by the Japanese officials, the Ki-27 was designed by Koyama Yasushi to have an air-cooled radial engine and fixed landing gear. The aircraft had the Nakajima trademark wing with a straight leading edge and tapered trailing edge which would reappear again on the Ki-43, Ki-44, and Ki-84.
The Ki-27 made its first flight on 15 October 1936. Although it had a slower top speed and worse climb performance than its competitors^. the Army chose the Nakajima design for its outstanding turning ability granted by its remarkably low wing loading. The Army ordered 10 pre-production samples (Ki-27a) for further testing, which featured an enclosed cockpit with sliding canopy and larger wings.
The type was officially accepted into service in 1937 as the Army Type 97 Fighter. In addition to Nakajima, the Ki-27 was also manufactured by Tachikawa Aircraft Company Ltd and Manshukoku Hikoki Seizo KK, with a total of 3,368 built before production ended in 1942.


The Ki-27 was the Imperial Japanese Army Air Force's main fighter until the start of World War II. When placed into combat service over northern China in March 1938, the Ki-27 enjoyed air superiority until the introduction of the faster Soviet-built Polikarpov I-16 fighters by the Chinese.

In the 1939 Battle of Khalkhin Gol against the USSR in Mongolia, the Ki-27 faced both Polikarpov I-15 biplane and Polikarpov I-16 monoplane fighters. In the initial phase of the conflict, its performance was a match for the early model I-16s, and was considerably superior to the I-15 biplane. With better trained Ki-27 pilots, the IJAAF gained aerial superiority. The Ki-27 was armed with two 7.7 mm (.303 in) machine guns and as with most aircraft of the period, lacked armor protection for the pilot, as well as self-sealing or fire suppression in the fuel tanks.
Later, the Soviet Air Force received improved I-16s. The faster, more heavily armed (with twin wing-mounted 20mm cannon) and armored I-16 now nullified the Ki-27s previous advantages and it could now escape from the Ki-27 in a dive. The VVS introduced new tactics consisting of flying in large tightly knit formations, attacking with altitude and/or speed advantage and hit-and-run (high-energy) tactics much as Claire Chennault would later formulate for the 1941-era Flying Tigers (likewise to fly against Japanese forces).
Japanese losses mounted but despite this they claimed 1,340 downed aircraft (six times the admitted Soviet losses and three times as many as Soviet aircraft admitted to being in the theatre) though similar discrepancies were common worldwide before gun cameras became widespread. Japanese losses numbered 120 (including Ki-10s) while the Russians claimed 215 vs. a peak Japanese strength of 200 fighters. Top scoring pilot of the incident and top scoring IJAAF pilot on the Ki-27 and overall World War II IJAAF ace was Warrant Officer Hiromichi Shinohara, who claimed 58 Soviet planes (including an IJAAF record of 11 in one day) whilst flying Ki-27s, only to be shot down himself by a number of I-16s on 27 August 1939.
The preference of Japanese fighter pilots for the Ki-27's high rate of turn caused the Army to focus excessively on maneuverability, a decision which later handicapped the development of faster and more heavily armed fighters. The Ki-27 served until the beginning of World War II in the Pacific, escorting bombers attacking Malaya, Singapore, Netherlands East Indies, Burma and the Philippines (where it initially fared poorly against the Brewster F2A Buffalo).
The type also saw extensive action against the American Volunteer Group in the early months of the war. Soon outclassed by the American Curtiss P-40 Warhawks, the Ki-27 was replaced in front line service by the Nakajima Ki-43, while surviving examples continued to serve as a trainer.
The Ki-27 was also exported for use with Manchukuo and Thai armed forces, seeing combat with both. In Thai service, Ki-27s reportedly damaged two North American P-51 Mustangs and shot down one Lockheed P-38 Lightning.
In the final months of the war, desperate lack of aircraft forced the Japanese to utilize all available machines, and the Ki-27 and 79 were no exception. Some were equipped with up to 500 kg (1,100 lb) of explosives for kamikaze attacks, but some were redeployed as fighters, suffering terrible losses as on 16 February 1945 when the 39th Educational Flight Regiment scrambled 16 Ki-79 trainers from Yokoshiba Airfield to oppose a massive air raid from U.S. Task Force 58 carrier group, losing six aircraft with more damaged and five pilots killed, in return damaging at least one Hellcat and possibly downing a second.

Mitsubishi A5M2b Claude

Here are some images of Special Hobby's 1/32 scale Mitsubishi A5M2b Claude.

From Wikipedia'
The Mitsubishi A5M, Japanese Navy designation was "Type 96 carrier-based fighter" (九六式艦上戦闘機) was a Japanese carrier-based fighter aircraft. It was the world's first monoplane shipboard fighter and the direct ancestor of the famous Mitsubishi A6M 'Zero'. The Allied reporting name was Claude.
In 1934, the Imperial Japanese Navy prepared a specification for an advanced fighter, requiring a maximum speed of 350 km/h (220 mph) at 3,000 m (9,840 ft) and able to climb to 5,000 m (16,400 ft) in 6.5 minutes. This 9-shi (1934) specification produced designs from both Mitsubishi and Nakajima.

First prototype with inverted gull wing

 

Mitsubishi assigned the task of designing the new fighter to a team led by Jiro Horikoshi (later responsible for the famous A6M Zero). The resulting design, designated Ka-14 by Mitsubishi, was an all-metal low-wing fighter, with a thin elliptical inverted gull wing and a fixed undercarriage, which was chosen as the increase in performance (estimated as 10% in drag, but only a mere 3% increase in maximum speed) arising from use of a retractable undercarriage was not felt to justify the extra weight. The first prototype, powered by a 447 kW (600 hp) Nakajima Kotobuki 5 radial engine, flew on 4 February 1935. The aircraft far exceeded the requirements of the specification, with a maximum speed of 450 km/h (279 mph) being reached. The second prototype was fitted with a revised, ungulled wing, and after various changes to maximize maneuverability and reduce drag, was ordered into production as the A5M.
With the Ka-14 demonstrating excellent performance, the Imperial Japanese Army Air Force ordered a single modified prototype for evaluation as the Ki-18. While this demonstrated similar performance to the Navy aircraft and hence was far faster than the IJAAF's current fighter, the Kawasaki Ki-10 biplane, the type was rejected by the army owing to its reduced maneuverability. The Army then produced a specification for an improved advanced fighter to replace the Ki-10. Mitsubishi, busy turning the Ka-14 into the A5M, submitted a minimally changed aircraft as the Ki-33, this being defeated by Nakajima's competing aircraft, which was ordered into service as the Ki-27.

The aircraft entered service in early 1937, soon seeing action in pitched aerial battles at the start of the Second Sino-Japanese War, including air-to-air battles with the Republic of China Air Force's Boeing P-26C Model 281 "Peashooters" in what was the world's first-ever aerial dogfighting and kills between monoplane fighters built of mostly metal.

Chinese Nationalist pilots, primarily flying the Curtiss Hawk III, put up a valiant fight against the Japanese, but the A5M was the better of almost every fighter aircraft it encountered. Though armed with only a pair of 7.7 mm machine-guns, the new fighter proved effective and damage-tolerant, with excellent maneuverability and robust construction. Later on A5M's also provided much-needed escorts for the then-modern but vulnerable Mitsubishi G3M bombers.
The Mitsubishi team continued to improve the A5M, working through versions until the final A5M4, which carried an external underside drop tank to provide fuel for extended range.
The A5M's most competitive adversary in the air was the Polikarpov I-16, a fast and heavily armed fighter flown by both Chinese Air Force regulars and Soviet volunteers. Fierce air battles in 1938, especially on 18 February and 29 April, ranked among the largest air battles ever fought at the time. The battle of 29 April saw 67 Polikarpov fighters against 18 G3Ms escorted by 27 A5Ms. Each side claimed victory: the Chinese/Soviet side claimed 21 Japanese aircraft (11 fighters and 10 bombers) shot down with 50 of its own airmen killed; the Japanese claimed only two G3Ms and two A5Ms shot down with no less than 40 Chinese planes shot down.
104 A5M aircraft were modified to accommodate a two-seater cockpit. This version, used for pilot training, was dubbed the A5M4-K. K version planes continued to be used for pilot training long after standard A5Ms left front-line service.
Almost all A5Ms had open cockpits. A closed cockpit was tried but found little favor among Navy aviators. All had fixed, non-retractable undercarriage. Wheel spats were a feature of standard fighters but not training planes.
The Flying Tigers encountered the Type 96, although not officially, and one was shot down at Mingaladon airfield, Burma on 29 January 1942.
Some A5Ms remained in service at the end of 1941 when the United States entered World War II in the Pacific. US intelligence sources believed the A5M still served as Japan's primary Navy fighter, when in fact the A6M 'Zero' had replaced it on first-line aircraft carriers and with the Tainan Air Group in Taiwan. Other Japanese carriers and air groups continued to use the A5M until production of the Zero caught up with demand. The last combat actions with the A5M as a fighter took place at the Battle of the Coral Sea on 7 May 1942, when two A5Ms and four A6Ms of the Japanese carrier Shōhō fought against US planes that sank their carrier.
In the closing months of the war most remaining A5M airframes were used for kamikaze attacks.

Nakajima Ki-43 Oscar

Here are some more images of Hasegawa's 1/32 scale Nakajima Ki-43 Oscar with Manchukuo air corps markings. From Wikipedia "

The Nakajima Ki-43 Hayabusa (隼, "Peregrine Falcon") was a single-engine land-based tactical fighter used by the Imperial Japanese Army Air Force in World War II. The army designation was "Army Type 1 Fighter" (一式戦闘機); the Allied codename was "Oscar", but it was often called the "Army Zero" by American pilots for its resemblance to the Mitsubishi A6M Zero. Like the Japanese Navy's A6M Zero, the radial-engined Ki-43 was light and easy to fly. The Ki-43 was legendary for its combat performance in East Asia in the early years of the war.

It could outmaneuver any opponent, but did not have armor or self-sealing tanks. Its armament was poor until the last version in 1944. In spite of its drawbacks, the Ki-43 shot down more Allied aircraft than any other Japanese fighter and almost all the JAAF'S aces achieved most of their kills in it. Allied pilots often reported that the nimble Ki-43s were difficult targets, but burned easily or broke apart with few hits.

Total production amounted to 5,919 aircraft. Many of these were used during the last months of the war for kamikaze missions against the American fleet.

The Manchukuo Imperial Air Force (Chinese: 大満州帝国空軍 Dà Mǎnzhōu Dìguó Kōngjūn) was established in February 1937, initially with 30 men selected from the Manchukuo Imperial Army and trained at the Japanese Kwantung Army aircraft arsenal in Harbin. The official air force's predecessor was the Manchukuo Air Transport Company (later re-named the Manchukuo National Airways) a paramilitary airline formed in 1931, which undertook transport and reconnaissance missions for the Japanese military.

The first air unit of the Manchukuo Air Force was established at the airfield in Xinjing, under the command of 1st Lieutenant Uta, and initially had only one aircraft: a French-built Nieuport-Delage NiD 29 biplane. Kawasaki Type 88 (KDA-2) light bombers and Nakajima Type 91 fighters were later supplied from Japan.

A second air unit was established in Fengtien and the third air unit in Harbin from 1938-1939. In July 1940, an Air Defense HQ was created in Xinjing.

Initially, only Japanese pilots and ground crews were also deployed. After 1940, the Japanese allowed native ethnic Manchus to receive pilot training. On 30 August 1940, a flight school was established in Fengtien to teach both military and civil pilots. The training program received a severe setback in January 1941 when approximately 100 pilot cadets rebelled, and fled to join to anti-Japanese guerillas after killing their instructors. During September to October 1942 the school received more than twenty training aircraft, including Tachikawa Ki-9 "Spruce", Tachikawa Ki-55 "Ida" and Mansyū Ki-79 advanced trainers

In addition, a transport section with three Nakajima Ki-34 passenger aircraft was established to serve the needs of the imperial court. Additional Junkers Ju-86Z-2, Tachikawa Ki-54 "Hickory" and Manshū Hayabusa provided for government transportation needs.

From 1944, the Manchukuo Imperial Air Force came under the command of the Japanese 2nd Air Army. At that point, it had around 100 to 120 combat aircraft.

From 1941 to the end of World War II, the main equipment of the Manchukuo Air Force was the Nakajima Ki-27b "Nate" light fighter. Money to pay for these fighters was “donated” by various Japanese companies based in Manchukuo. Primarily a fighter force, the only tactical bomber in Manchukuo service during World War II was the Kawasaki Ki-32.

The Manchukuo Air Force requested Type 1 Nakajima Ki-43 IIa Hayabusa "Oscar" and Type 2 Nakajima Ki-44 IIb Shoki "Tojo" fighter/interceptors from Japan in early 1945. However, these more advanced aircraft were supplied in only small numbers.

As American air raids against Manchukuo increased in frequency towards the end of the war, the Manchukuo Air Force resorted to kamikaze tactics, with the first successful ramming attack (by a Ki-27) on a USAAF B-29 Superfortress strategic bomber occurring in December 1944. The Manchukuo Air Force also suffered from a chronic shortage of fuel, as Japanese military aviation had first claim to supplies.

In 1945, the American air raids against Manchuria decreased and the threat of the Soviet invasion increased. The Manchukuo Air Force changed its training from interception to emphasize ground attack against armored vehicles. During the Soviet Union's invasion of Manchukuo, the Japanese 2nd Air Army ordered the Manchukuo Air Force to train for suicide attacks against Soviet tanks. However, the war ended before attack plans could be executed.
