Armament. Two 30-mm guns No-155 (80 rounds per barrel) and two 20-mm guns No-5 (160 rounds per barrel), two 50-kg or one 250-kg bomb on an external sling.
Structurally, the Ki-83 fighter was a twin-engined all-metal monoplane. The wing of the laminar profile, in the area of the center section, had a transverse V of 2 °, the consoles were straight. Automatic slats - along almost the entire leading edge of the wing. The fuselage and wing skins are made with large-area duralumin sheets to minimize the number of seams. The vertical tail was structurally borrowed from the previous Ki-46 reconnaissance aircraft.
Engines - Na-211-Ru with a takeoff power of 2200 hp, at an altitude of 6800 m they developed 2130 hp, and at 10300 meters - 1920 hp. The propellers are metal, four-blade variable pitch with a diameter of 3.5 m. The exhaust system was original. The manifolds from the cylinders through the turbocharger were brought out to the rear of the engine nacelles, without protruding beyond their dimensions and creating additional jet thrust (see photo).
Tricycle landing gear with a tail wheel, completely retracted, the main supports - in the engine nacelles, the tail - in the fuselage.
Armament was installed in the forward fuselage. Below were two 30-mm No-155 cannons with 80 rounds of ammunition per barrel, slightly higher, shifted inward - a pair of 20-mm No-5 cannons, 160 rounds per barrel. The barrels of the guns did not protrude beyond the dimensions of the glider. External suspension of a pair of 50 kg bombs or one 250 kg bombs was also allowed.
Teardrop-shaped cockpit canopy, the bullet-resistant windshield was 60 mm thick. The pilot's seat is one-piece stamped from a 12-mm armor plate with an 8-mm armored headrest. A 12-mm armor plate was located in front of the cockpit. Behind the pilot there is an 8-mm armored partition separating the cockpit from the 1560 liter main fuel tank located behind. The tank was fully sealed with 16 mm thick multi-layer rubber. Two wing tanks with a volume of 170 and 250 liters were also sealed and had the ability to transfer fuel from one tank to another. The total fuel volume was 2400 liters. All tanks had an automatic fire extinguishing system. A pair of 220-liter outboard tanks could be hung under the wings.
Closer to the tail was the second crew member's cockpit, which did not protrude beyond the fuselage contours. Only on both sides there were two small windows and a small window on top. The navigator's seat was directed along the flight path and was also made of 12 mm armor plate. From the navigator's back, she was protected by an 8-mm armored wall.
The fighter's instrumentation was quite sophisticated, including an autopilot rare for Japanese aircraft. It is unlikely that the Ki-83 fighter, if it were adopted, could have a strong influence on the outcome of the war, but it certainly could have caused a lot of unpleasant moments for American aviation.
By the time the war ended, the Japanese command planned to create a reconnaissance version of the Ki-83-Otsu on the basis of the Ki-83, another Ki-95 reconnaissance aircraft, into which one of the destroyed Ki-83 prototypes began to be rebuilt with the replacement of the tail section. The Ki-95 scout was seen as a promising replacement for the famous Ki-46.
