Tactics

The Ki-102 Otsu can be used as a heavy fighter against bombers (although not its preliminary role). It can destroy Medium and Heavy bombers with a single round from its 57mm cannon. But it is not effective against Light Bombers and other aircraft due to their size and manoeuvrability. It is recommended that you climb at an angle of around 15° to get the maximum performance out of your engines of 250kmh or higher. If your speed goes below 250kmh, lower your angle of climb. When engaging bombers, make sure you are higher than them. It is important that you can perform a steep and direct attack higher than the enemy, so you have less spread from your 57mm and a clearer, more accurate shot against them. Staying behind a bomber is a dangerous move, for any aircraft, as your aircraft is openly prone to the gunners of the bomber, and can quickly engage you with high accuracy.

History of creation and combat usage

TOAaF1X.jpg

Two-seat twin-engine Kawasaki Ki-102 Army Type 4 Assault Plane (Allied reporting name: Randy). The Ki-102 was developed from the Ki-96, when a specification was ordered for a two-seat heavy fighter instead of a single-seat. Utilising most of the Ki-96's design, the Ki-102 had the same Ha-112-II radial engines and armament, but now had a two-seat crew emplacement. Along with the Ki-96, the Ki-102 was intended to replace the already in service Ki-45, which had soon become outclassed later in the war. However, the Ki-102 remained in home-defence operations, seeing limited service.

Takeo Doi, the designer of many of the Army's aircraft including the Ki-96, developed the new Ki-102 design and presented it to the Army. After the Army had inspected the designs and estimated its performance, 3 prototypes were ordered and the first prototype made its maiden flight in March 1944. It was soon anticipated that the Ki-102 (being a development of the already successful Ki-96) showed very promising results which the Army then ordered for a further 20 pre-production aircraft.

The Ki-102 came in 3 variants. The first production model was known as the Ki-102 Ko. This was a high-altitude fighter armed with forward firing 2 x 20mm Ho-5 cannons, 1 x 37mm Ho-203 cannon and had turbo-supercharged Ha-112-II Ru engines which gave it exceptional high altitude performance. Secondly, came the Ki-102 Otsu. This was a ground-attack aircraft armed with forward firing 2 x 20mm Ho-5 cannons, 1 x 57mm Ho-401 cannon and a rear-ward facing 1 x 12.7mm Ho-103 machine gun to be used by the second crew member. Lastly, came the Ki-102 Hei which was to have been a dedicated night-fighter aircraft. It had an elongated fuselage, wider wingspan, and used the turbo-supercharged Ha-112-II Ru engines for increased high-altitude performance (same as the Ki-102 Ko). In addition, it was equipped with a radar, and armed with forward firing 2 x 30mm Ho-105 cannon and 2 x 20mm Ho-5 cannons in schräge musik configuration. The Ki-102 Hei remained a prototype when the war ended, with only 2 being built.

Although the Ki-102 was to be used in various roles, it never saw wide spread service. Only a few Ki-102 Otsu's saw limited service in Okinawa, and the rest stayed in home-defence. It was intended to use Kawasaki's Igo-1-B air-to-surface missile and act as a mother ship, carrying the Igo-1-B missile to a target. Had the Igo-1-B missile entered service, the Ki-102 Otsu would have been the designated carrier aircraft. Later in the war, the Army ordered a specification for a high-altitude fighter with a pressurised cabin. The Ki-102 would be the basis for this new specification, and was designated the Ki-108. Proving to be satisfactory during flight testing, it was proposed to make some minor adjustments to make the Ki-108 perform better in its high-altitude role. This new variant was designated the Ki-108 Kai (Kai = improved/modified) with an elongated fuselage and larger wing area. However, both aircraft remained in the prototype stage before the war ended. With the increasing intensity of the allied bombing campaign, the need for interceptors became a higher priority, and it was clear that the Ki-102 would not see wide-spread service, remaining in home-defence throughout the war.

Overall, 26 Ki-102 Ko, 207 Ki-102 Otsu and 2 Ki-102 Hei were produced, with only the Ki-102 Otsu seeing limited service.
