Description

This Ki-10-II (Commander) belongs to the 77th Hiko Sentai, which was created from the 8th Daitai. The unit participated in the China Incident, moving from its original base in Tachiarai, Japan, to various locations in Manchuria and China. Its main task was to support the ground troops in their offensive operations. The 8th Daitai scored several victories against Chinese planes in the early stages of the conflict, but faced more challenges when the Soviets supplied their allies with I-15 and I-16 fighters. Despite being outmatched by these faster and more modern planes, the 8th Daitai continued to use its Ki-10s alongside its limited number of Ki-27s, and even managed to shoot down some Soviet SB-2 and I-16 aircraft. On July 31st, 1938, the 8th Daitai changed its name and structure to become the 77th Sentai. The unit was separated from its maintenance crew and had no subordinate battalions, which gave it more mobility and flexibility to operate from different airfields with local ground support. The 77th Sentai also adopted a distinctive tail marking, consisting of a coloured field on the fin and rudder with thin horizontal white or blue stripes. Inside the field were two stylized arrowheads (sometimes called "seagulls") that looked like sevens on the right side (representing "77"). The colours of the field indicated the Chutai: blue for headquarters; white for 1st Chutai (with blue stripes and arrows); red for 2nd Chutai; and yellow (with blue stripes and arrows) for 3rd Chutai when it was formed.

It has been in the game since the start of the Open Beta Test prior to Update 1.27. The Ki-10-II C is no longer acquirable in the game but is retained by those who have obtained it before its removal. The Ki-10-II has a good turn rate, fair climb, low speed, and minimal armour. It is faster and climbs better than other biplanes, but has weaker guns and protection. The Ki-10-I can turn-fight well at low altitudes, but should avoid stalls and spins. Its 7.7 mm guns have low fire rate and poor belts. Stealth belt is the best choice. The Ki-10 should not attack armoured targets or bombers, but focus on other biplanes or slow monoplanes. Aim for the wings, not the fuselage. Teamwork is essential for the Ki-10.

Like many biplanes before and contemporaries of the Ki-10-II C, armour was not an option, survival was based on the pilot's grit. Armour added weight, weight the early biplanes could not afford to carry and still be a viable fighter. Flying in open cockpit and fabric-covered aircraft, the only protection the pilot had was to place his engine between him and his enemy, otherwise, the pilot was vulnerable. Typically aircraft like this have the engine at the nose of the aircraft, followed by the fuel tank and then the cockpit, all three critical components relatively crammed together. The pilot's toolbox had to contain situational awareness as he needed to know where the enemy was around him. Tracer rounds could easily ignite the fabric-covered aircraft or large fuel tanks, so it was imperative the pilot was the attacker, not the one being attacked and knowing where the enemies are at can help avoid getting shot at.

For such low-rank vehicles the order of research does not really matter. Improvements in firepower by new belts and new machine guns help a lot in arcade battles. For realistic mode, performance upgrades are more often necessary.

Usage in battles

The Ki-10-II's low speed and tight turning ability make it a great turn-fighter, like most Japanese light fighters. The Ki-10-II excels at low and slow turn fighting at very low altitudes where enemies cannot out-dive it. Additionally, it has a climb rate to climb away from enemy biplanes. Very fast dives should be avoided, as the wings will shear off at very high speeds. Similarly, turning stalls should be avoided, as the Ki-10-II has a tendency to enter uncontrollable spins.

Its twin 7.7 mm armament is the weakest in the game, as it has a lower fire rate than its contemporaries, the ShKAS, Browning, and MG 17. The belts are poor as well; Stealth is most recommended, as it has the most AP-derivative shells. Strafing attacks on all but the least armoured targets are not recommended; Artillery, Vehicles, and Landing Craft are good and soft targets, while the Ki-10-II's weak construction makes attacking AAA and bombers risky. All bombers are pretty much invulnerable to the Ki-10-II (Beaufort, A-26, etc.) unless you are extremely good at making consistent pilot shots. Cargo Ships, Tanks and pillboxes are also invulnerable to the Ki-10-II. Instead, the best Ki-10-II targets are other biplanes or slow monoplanes, such as P-26s, Fury Mk Is or Nimrod Mk Is. The best practice is to aim for the wings! The fuselage's of all planes will absorb your shells like a sponge. Like most other planes, the Ki-10-II works best in numbers. Ki-10 pilots should focus primarily on sticking together and working as a team.

History

The Kawasaki Ki-10 was the last Biplane fighter used by the Japanese Army. Introduced in 1935, it beat the competing Nakajima Ki-11 (which would later be refined as the Ki-27) as the Imperial Japanese Army Air Force placed more priority on manoeuvrability than speed. Its excellent manoeuvrability made it extremely popular with Japanese pilots, who demanded similar high manoeuvrability from newer aircraft. Over the course of its service, the fighter would be refined several times with the ultimate version, the Ki-10-II, appearing in 1937.

The Ki-10 saw service against Chinese air forces in the early stages of the Second Sino-Japanese War and against Soviet air forces during the battles of Khalkhin Gol (where it historically outperformed the Soviet I-15). It formed the backbone of the IJAAF fighter forces until 1940, but it was considered obsolete by Western military experts as early as 1938. By the start of the Pacific War, the Ki-10 had been regulated to training and courier roles, and received the Allied reporting name "Perry".

There are no known incidents where the Ki-10 engaged American- or British-crewed aircraft, though the Japanese fighter did fight Chinese National P-26s, and may have engaged British-built Gladiators, Italian CR.32s (predecessor of the CR.42), and Soviet I-15s, all crewed by Chinese pilots, during the early battles of the war.

Archive of the in-game description

Kawasaki Ki-10-II (Type 95-II, Allied reporting name: Perry) single-engine army fighter The first Ki-10 production fighters began to enter service in December 1935. Military pilots highly appreciated the new fighter's speed and rate of climb. However, Kawasaki soon began to get non-stop requests from troops asking them to improve the machine's horizontal manoeuvrability The predominant opinion in the Japanese aviation industry of that time period was that fighters should first of all meet the requirements of high manoeuvrability for the close-range combats ("dog fights") of World War I. In addition, the Ki-10 was noted to have inadequate longitudinal stability that made accurate aiming and firing more difficult. In response to these complaints, Takeo Doi presented a new version of the fighter, designated the Ki-10-II, in October 1937. The new plane had its upper wing span increased to improve manoeuvrability, which resulted in decreased wing load. Also, the tail section of the fuselage was lengthened to extend the empennage, which made the plane more stable. The designers managed to compensate completely for the increased drag after the plane's production standards were raised and, in particular, the airframe's surface was given a smoother finish. As a result, the Ki-10's manoeuvrability and takeoff/landing characteristics were noticeably improved, even though the plane retained the same engine and other flight performance parameters remained unchanged. 290 Ki-10-II fighters left the Kawasaki factory floor (located in the city of Gifu) during production, up until December 1938, when the machine's production ceased. The Ki-10-I and the Ki-10-II became the most advanced biplane fighters in Japanese aviation. They took active part in combat operations in the Sino-Japanese War and in the Khalkhyn Gol conflict. Ki-10 aircraft became obsolete by the beginning of the Pacific War, and were mainly used as training machines. In 1939, a practically undamaged Ki-10-II fighter was captured by the Chinese. This aircraft later appeared in the USSR. The machine was thoroughly studied there, and flight tests were even conducted at the Air Force Research Institute. Soviet test pilots noted that the Japanese fighter had high production standards and was easy to operate and maintain. It was not difficult to pilot, but its stability was considered inadequate, and its spin characteristics were believed to be poor. But in general, despite a number of disadvantages, the Ki-10-II was regarded as a very strong air-combat opponent which could fight Soviet I-15 fighters on an equal footing.
