The Ki-45, the Toryu (Dragon Slayer) heavy twin-engined fighter, designed according to the 1937 technical assignment, has become one of the most important combat aircraft of the Japanese Air Force.

The first 6 prototypes and 12 pre-production vehicles were tested in January 1939, but the vehicle had to be refined before the aircraft was adopted. Only in the fall of 1942, the Toryu, equipped with Na-25 1050 hp radial engines, began to enter service with the Japanese Air Force as the Ki-45 KAI-a fighter and the Ki-45 KAI-b multipurpose anti-ship aircraft.

The next modification of the Ki-45 KAI-c was a night fighter and was powered by a Mitsubishi engine.

The latest modification - Ki-45 KAI-d - was again an assault and anti-ship aircraft with modified armament and the ability to carry 500 kg of bombs. 477 Ki-45 KAI-c night fighters and 1198 vehicles of the other three modifications combined were manufactured.
