The Ki-45 ko Toryu is a Rank I Japanese twin-engine fighter with a battle rating of 2.0 (AB), 2.3 (RB), and 2.7 (SB). It was introduced in Update 1.31.

  Being a classed as a heavy fighter, the Ki-45 isn't the best in the maneuverability category. However, for a heavy fighter, it maneuvers very well. It is even capable of out-turning aircraft such as the P-47D-25. Unlike heavy fighters of other nations, the Ki-45 series does not feature aircraft with large amounts of heavy weaponry. This is a major downside, considering how heavy fighters traditionally give up maneuverability and speed for armament. Instead, the Ki-45s utilize more of an equilibrium between maneuverability, speed, and armament. These are what makes the Ki-45 both a capable dog-fighter, and bomber hunter.

  The first variant of the Ki-45, the Ki-45 ko, features the least "hard hitting" armament of the series. Wielding two Ho-103 12.7 mm machine guns and one Ho-3 20 mm cannon, this aircraft is the best suited for dog-fighting as it has the largest total ammunition pool out of all the Toryus. Sitting at tier 1, this beast is more than capable of shooting down anything it may face.

  The Ki-45 also has a very good turn rate, unlike other heavy fighters. Although the aircraft itself is large and presents an "easy target" in many players' minds, the Ki-45 is rather nimble. Use this to your advantage when engaging enemy aircraft. Unfortunately, the Ki-45 is a heavy fighter, meaning its turn time is still not on par with other aircraft such as the F2A-3. In certain cases, the Ki-45 pilot may have to rely on his or her tail gunner to get the job done. The "ko" version of the Ki-45 features a 7.92 mm Type 98 machine gun with 1050 rounds. Although lackluster, with shot placement it is possible to destroy enemies on the aircraft's tail. Aim for the pilot or the engine, as those are generally the weakest points on most aircraft. If the tailing enemy is a bi-plane, aim for the wings since they are very fragile.

  The Toryu is also rather fragile for a heavy fighter. Although it does feature two engines, the Ki-45 does not have very much armor protection. Only the back of the pilot's seat has armor, leaving both the gunner and engines unprotected. This can prove costly in a fight. If one does find themselves tailed, call upon teammates for assistance.

Survivability and armour

  • 16 mm Steel plates behind the pilot.


Offensive armament

The Ki-45 ko is armed with:

  • 1 x 20 mm Ho-3 cannon, belly-mounted (100 rpg)
  • 2 x 12.7 mm Ho-103 machine guns, nose-mounted (350 rpg = 700 total)

Defensive armament

The Ki-45 ko is defended by:

  • 1 x 7.92 mm Type 98 machine gun, dorsal turret (1,050 rpg)

Usage in the battles

The Ki-45 ko's armament is much more suited for dog-fighting than its later, 37 mm cannon-armed variants. With a moderate ammunition pool, it is easily possible to destroy multiple enemies with this aircraft. It is recommended to use the 20 mm cannon only when the pilot is sure he or she will hit the enemy aircraft, as it only holds 100 shells. The 12.7 mm machine guns are where most of the damage will be done at a range.

  • Instead of focusing on armament like other heavy fighters, the Ki-45 is more balanced between armament and flight performance. While the default ammunition belts for both weapons on the Ki-45 ko are workable, it can help to upgrade. Unlocking the flight performance modules will help drastically in dogfights and turn fights.

Pros and cons


  • 7.92 mm tail gun
  • Fairly good speed
  • 16.5 mm of armor in pilot's seat
  • Good maneuverability
  • Two engine design
  • Effective armament
  • Very good climb rate


  • Beat in turn fights by some aircraft
  • Prone to fuel and engine fires
  • Locks up at high speeds
  • Mediocre roll rate, gets worse as speed increases (compression)
  • Limited ammunition for all weapons
  • Lack of protection around fuel tanks, engines, and gunner


Initially designed to be a bomber escort, the Ki-45 was first deployed in what is now China and Vietnam. It was found to be easily outclassed by P-40s piloted by the Flying Tigers. As a result, the Ki-45's role was changed to anti-shipping and ground attack, where it performed satisfactorily. Nonetheless, the Ki-45's greatest strength proved to be its bomber intercepting capabilities. Heavily armed with 37 mm cannon, the Toryu (Dragon Slayer) could destroy heavy bombers with ease. As the war progressed, the need for an interceptor to defend the Japanese mainland was ever present. Soon, the Ki-45 was deployed to counter B-29 Superfortress raids. Although its armament was clearly deadly enough, the Ki-45 suffered at high altitudes. Pilots soon resorted to ramming attacks against the Superfortress'. Special attack groups specifically designed for this purpose formed, but by late 1945 Imperial Japan's fate had been sealed.
