The Ki-49's role is a low-altitude light bomber capable of destroying ground targets such as pillboxes and tanks. Although hindered by a low total bomb capacity, this aircraft is renowned for its impressive manoeuvrability. This being said, it is very easy for the Ki-49 to hover above an area and drop all of its payloads rather quickly. Heavy bombers such as the G8N1 Renzan have a harder time due to their sheer size and slow rate of turn. Make sure to select the 4 x 250 kg bomb loadouts if attacking targets like tanks, pillboxes, or smaller ships.

Being a bomber, speed is not necessarily an important attribute, however, payload and armament are. Upgrading the bombs allows for more target flexibility and damage potential while turret upgrades will help survivability. The turret belts and the "new turrets" upgrades are useful. The "new turrets" upgrade will allow you to fire the turrets for longer periods of time and having access to multiple ammunition belts is also helpful. The engine upgrades are also useful in that they will help you reach your target faster and will control engine temperature. Having all of the weapons upgrades will help drastically in unlocking the other modules on this aircraft.

{{main|Army Type 94 GPHE (50 kg)|Army Type 92 GPHE (250 kg)|Army Type 92 GPHE (500 kg)}}
 +
 
 +
The '''''{{PAGENAME}}''''' can be outfitted with the following ordnance:
 +
 
 +
* 12 x 50 kg Army Type 94 GPHE bombs (600 kg total)
 +
* 4 x 250 kg Army Type 92 GPHE bombs (1,000 kg total)
 +
* 1 x 500 kg Army Type 92 GPHE bomb (500 kg total)
 +
 
 +
The Ki-49-IIb/L shares the same somewhat lacking bombload options as all other members the [[Ki-49 (Family)|Ki-49 family]] , able to carry a maximum bomb load of 1,000 kg (in the form of 4 x 250 kg bombs). By comparison many bombers around this battle rating can carry double that. The best loadout is generally the 4 x 250 kg bombs as it is by far the largest total load; the 12 x 50 kg bombs are not much use on account of their small size and thus limited damage. Although a reduction in total bomb load the single 500 kg bomb can be useful if you want to kill a ground target, due to it's larger blast radius.

The '''''{{PAGENAME}}''''' is defended by:
 +
 
 +
* 1 x 20 mm Ho-1 cannon, dorsal turret (180 rpg)
 +
* 1 x 12.7 mm Ho-104 machine gun, nose turret (250 rpg)
 +
* 1 x 12.7 mm Ho-104 machine gun, ventral turret (250 rpg)

 +
* 1 x 7.7 mm Type 89 machine gun, 2 x beam turrets (414 rpg)
 +
 
 +
The defensive armament of the Ki-49-IIb/L is identical to the preceding [[Ki-49-IIb]] , and similar to all other members of the [[Ki-49 (Family)|Ki-49 family]]. While the 20 mm cannon is certainly nice to have, its effectiveness is somewhat limited by being blocked from shooting directly rearwards by the aircraft's tail; it also cannot shoot downwards thanks to its location on the top of the aircraft. The rest of the defensive armament is un-remarkable consisting of single 12.7 and 7.7 mm machine guns.

 +
This aircraft has the ability to hold up to 1,000 kg of bombs in several different variations. 12 x 50 kg bombs, 4 x 250 kg bombs, 1 x 500 kg bomb. Use the 12 x 50 kg bombs to attack light tanks and light pillboxes. They are not viable against bigger targets since direct hits are needed to destroy. This payload is particularly useful on maps like Zhengzhou where there is an abundance on non-moving targets (light pillboxes). Use the 4 x 250 kg bomb versions to destroy heavier targets such as medium tanks, pillboxes, destroyers, and cargo ships. Use the 500 kg bomb to destroy targets like carriers or mini-bases.
  
−
=== Suspended weaponry ===
+
If attacked by fighters, it is important to remember and recognize the Ki-49's turning capabilities. It is actually possible to win lateral turn fights against fighters with this aircraft in arcade battles. Try not to act like a "sitting duck" because the Ki-49 features little armour protection and has limited defensive capabilities as far as weapons go. If you are in a sticky situation, the hard-hitting 20 mm dorsal cannon is deadly. The only problem is that it's not located directly on the tail. If an enemy is directly behind or below the Ki-49, the 20 mm tail gunner's arc will not reach it. Therefore, you may need to change altitude in order to have the enemy plane both above and behind you. Pulling hard manoeuvres will throw the enemy off and allow you to set up for more defensive fire.

=== Defensive weaponry ===
+
In arcade battles, this aircraft is particularly proficient at bombing bases, especially with a maxed reload crew skill. Since the Ki-49 can virtually turn on a dime, instead of having to line up longer bombing runs like heavy bombers you can "hover" over the base or airfield and attempt dive attacks. The 500 kg bomb is particularly useful here because you only have to drop one bomb instead of spamming multiple. It's also possible to use this same tactic against pillboxes or tanks. With fighter cover, a good reload time skill and good aim it's possible to destroy dozens of ground units.

== Usage in the battles ==
+
Although unconventional, this aircraft is a fantastic weapon if you want to bait the enemy. Ideally, you would want to attract a higher flying enemy down to you and to get into a turnfight. This way, depending on the enemy aircraft you can outmanoeuvre and distract him while teammates fly down to finish him off.

 +
The best way of grinding with this aircraft is to play cautiously and to use communication. As with any bomber, if you're caught alone or off guard you are as good as dead. Although not a sure tactic, having a fighter escort will boost RP gains drastically. This goes for both Arcade and Realistic battles. Generally, try to destroy as many targets as possible without wasting bombs. If done in a speedy fashion it is possible to drop multiple payloads in RB. The same goes for simulator battles. In Arcade battles, having a high reload speed and a fighter escort will allow for constant bombardment. If done correctly, flying the Ki-49 in all modes will net you large amounts of RP.
 +
 
 +
In realistic battles, your gunners might deter the stray fighter, but won't deter a horde of them. American fighters think you are the perfect target for .50 cal machine guns. What to do? Wait out the battle patiently. In all Realistic Battles, fights will get dragged to lower altitudes, and you can start climbing and head into the main are once you are high enough. One other strategy is to rush attack. Take out the 250 kg bombs and destroy four Pillboxes and then run back to base immediately to restock. This will allow for fighter support to come to you while you head back to base.

;Nakajima Ki-49-II Donryu Army Bomber, type 100 model 2 (code name "''Helen''")
 +
 
 +
Prior to the outbreak of the War in the Pacific, the Japanese utilised the Ki-49 in China where it served well. It wasn't until the spring of 1942 that the Japanese military determined that the Ki-49 should be fitted with upgraded engines, namely the Nakajima Ha-109 radial piston engines which were rated at 1450 hp. Upgrading the engines, however, required slight modification of the engine nacelles to accommodate the newer engines even though they were roughly the same size as the original engines. Unfortunately, the oil cooler would not fit inside the nacelle along with the new engine and was instead mounted on the exterior of the nacelle. Other changes were also made to improve combat conditions of this aircraft: upgraded armour protection protecting the aircrew was installed along with self-sealing fuel tanks and a bombsight. The defensive armament remained similar to that of the Ki-49-I, however, the Type 89 machine guns were replaced with Type 98 7.92 mm machine guns (which were based on the Rheinmetall-Borsig MG.15). The normal bomb-carrying capacity of the aircraft was increased to 1,000 kg. A few short months later in August of 1942, this new version of the Donryu entered production under the designation Ki-49-IIa (model 2 Ko).
 +
 
 +
Quickly it was determined that the defensive machine guns were proven to be ineffective against Allied fighters and this required a new modification, which became the Ki-49-IIb (model 2 Otsu) implemented with stronger defensive weaponry. In the bow, stern, and ventral firing positions, the 7.92 mm Type 98 machine guns were replaced with 12.7 mm Ho-103 machine guns (the Type 1 Japanese version of the .50 cal Browning M2 machine guns). The two guns on the aircraft's sides were replaced with the original 7.7 mm Type 89 machine guns removed during the Ki-49-Ia upgrade. The bomb load remained unchanged at 1,000 kg. In later series, the Ki-49-IIb's common exhaust tube was replaced with several individual pipes. Even though the Ki-49-II bombers went through several revisions and upgrades, they were unable to completely replace the older models still in service. These bombers were used mainly in New Guinea, and China, and, in October of 1944, they were transferred to the Philippines where they actively participated in the Battle of Leyte Gulf. The Ki-49 was utilised as a jack-of-all-trades aircraft as she was used as both a day and a night bomber, long-range reconnaissance, transport, and anti-submarine patrols to name a few. Towards the end of the war, the Ki-49s were assigned to kamikaze units and modified for such action. Modifications for the kamikaze missions included stripping out all of the defensive armaments, the crew was reduced to two pilots and the bomb load was increased to 1,600 kg. Production of the Ki-49 ceased in December of 1944. In all its different variants, a total of 819 Ki-49s were constructed.
 +
 
 +
The first unit to receive Donryus was the 61st Sentai in China. An unknown amount of Ki-49s was involved in the Battle of Okinawa in 1945.

Nakajima Ki-49-II Donryu Army Bomber, type 100 model 2 (code name "Helen")
 +
 
 +
In the spring of 1942, it was decided that the Ki-49 should be fitted with new engines, the Nakajima Ha-109 radial piston engines, rated at 1450 hp. This required only a slight modification of the engine nacelles, as the new engine was a similar size to that of its predecessor. However, the oil cooler could not fit inside the nacelle along with the engine and was put outside, instead. Other changes were made to improve combat conditions: the armour protecting the airplane's crew was upgraded and self-sealing fuel tanks were installed, as well as a new bomb sight.
 +
 
 +
The defensive armament remained similar to that of the Ki-49-I, but the Type 89 machine guns were replaced with 7.92 mm Type 98 machine guns (which were based on the Rheinmetall-Borsig MG.15). Normal bomb carrying capacity was increased to 1,000 kg.
 +
 
 +
In August of 1942, the new version of the Donryu entered production, under the designation Ki-49-IIa (model 2Ko). However, the fighters' machine guns were soon proven to be ineffective against Allied fighters, so a new modification, the Ki-49-IIb (model 2Otsu) was designed with stronger defensive weaponry. In the bow, stern, and lower firing locations, the 7.92 mm Type 98 machine guns were replaced with 12.7 mm Ho-103 machine guns (the Type 1 Japanese version of the .50 cal Browning M2). The two guns on the aircraft's sides were replaced with the original 7.7 mm Type 89 machine guns. The bomb load remained unchanged.
 +
 
 +
In later series, the Ki-49-IIb's common exhaust was replaced with several separate pipes.
 +
 
 +
The Ki-49-II bombers were unable to completely replace the older models in service. They were used mainly in New Guinea and China, and, in October of 1944, they took active participation in the Battle of Leyte.
 +
 
 +
The Ki-49 was used as both a day and a night bomber as well as for long-range reconnaissance, transport, and anti-submarine patrols. Towards the end of the war, they were used in kamikaze units. For kamikaze missions, the Ki-49 was stripped of all defensive armaments, the crew was reduced to two pilots, and the bomb load was increased to 1,600 kg.
 +
 
 +
Production of the Ki-49 ceased in December of 1944. In all, 819 Ki-49s were constructed, including all variants.

Description

The Ki-49-IIb Donryu /Late is a rank III Japanese bomber with a battle rating of 3.7 (AB/RB) and 4.0 (SB). It has been in the game since the start of the Open Beta Test prior to Update 1.27.

The Ki-49's role is a low-altitude light bomber capable of destroying ground targets such as pillboxes and tanks. Although hindered by a low total bomb capacity, this aircraft is renowned for its impressive manoeuvrability. This being said, it is very easy for the Ki-49 to hover above an area and drop all of its payloads rather quickly. Heavy bombers such as the G8N1 Renzan have a harder time due to their sheer size and slow rate of turn. Make sure to select the 4 x 250 kg bomb loadouts if attacking targets like tanks, pillboxes, or smaller ships.

Being a bomber, speed is not necessarily an important attribute, however, payload and armament are. Upgrading the bombs allows for more target flexibility and damage potential while turret upgrades will help survivability. The turret belts and the "new turrets" upgrades are useful. The "new turrets" upgrade will allow you to fire the turrets for longer periods of time and having access to multiple ammunition belts is also helpful. The engine upgrades are also useful in that they will help you reach your target faster and will control engine temperature. Having all of the weapons upgrades will help drastically in unlocking the other modules on this aircraft.

Unlike the G4M1 and Ki-21-Ia, the Ki-49-IIb/L can fire its frontal turret at a slightly upwards angle and not just downards.
Main articles: Army Type 94 GPHE (50 kg), Army Type 92 GPHE (250 kg), Army Type 92 GPHE (500 kg)

The Ki-49-IIb/L can be outfitted with the following ordnance:

  • 12 x 50 kg Army Type 94 GPHE bombs (600 kg total)
  • 4 x 250 kg Army Type 92 GPHE bombs (1,000 kg total)
  • 1 x 500 kg Army Type 92 GPHE bomb (500 kg total)

The Ki-49-IIb/L shares the same somewhat lacking bombload options as all other members the Ki-49 family , able to carry a maximum bomb load of 1,000 kg (in the form of 4 x 250 kg bombs). By comparison many bombers around this battle rating can carry double that. The best loadout is generally the 4 x 250 kg bombs as it is by far the largest total load; the 12 x 50 kg bombs are not much use on account of their small size and thus limited damage. Although a reduction in total bomb load the single 500 kg bomb can be useful if you want to kill a ground target, due to it's larger blast radius.

The Ki-49-IIb/L is defended by:

  • 1 x 20 mm Ho-1 cannon, dorsal turret (180 rpg)
  • 1 x 12.7 mm Ho-104 machine gun, nose turret (250 rpg)
  • 1 x 12.7 mm Ho-104 machine gun, ventral turret (250 rpg)
  • 1 x 12.7 mm Ho-104 machine gun, tail turret (250 rpg)
  • 1 x 7.7 mm Type 89 machine gun, 2 x beam turrets (414 rpg)

The defensive armament of the Ki-49-IIb/L is identical to the preceding Ki-49-IIb , and similar to all other members of the Ki-49 family. While the 20 mm cannon is certainly nice to have, its effectiveness is somewhat limited by being blocked from shooting directly rearwards by the aircraft's tail; it also cannot shoot downwards thanks to its location on the top of the aircraft. The rest of the defensive armament is un-remarkable consisting of single 12.7 and 7.7 mm machine guns.

Usage in battles

The front gunner will be an important asset in RB. Once you have expended the bomb payload, this gunner can take out soft ground targets.

This aircraft has the ability to hold up to 1,000 kg of bombs in several different variations. 12 x 50 kg bombs, 4 x 250 kg bombs, 1 x 500 kg bomb. Use the 12 x 50 kg bombs to attack light tanks and light pillboxes. They are not viable against bigger targets since direct hits are needed to destroy. This payload is particularly useful on maps like Zhengzhou where there is an abundance on non-moving targets (light pillboxes). Use the 4 x 250 kg bomb versions to destroy heavier targets such as medium tanks, pillboxes, destroyers, and cargo ships. Use the 500 kg bomb to destroy targets like carriers or mini-bases.

If attacked by fighters, it is important to remember and recognize the Ki-49's turning capabilities. It is actually possible to win lateral turn fights against fighters with this aircraft in arcade battles. Try not to act like a "sitting duck" because the Ki-49 features little armour protection and has limited defensive capabilities as far as weapons go. If you are in a sticky situation, the hard-hitting 20 mm dorsal cannon is deadly. The only problem is that it's not located directly on the tail. If an enemy is directly behind or below the Ki-49, the 20 mm tail gunner's arc will not reach it. Therefore, you may need to change altitude in order to have the enemy plane both above and behind you. Pulling hard manoeuvres will throw the enemy off and allow you to set up for more defensive fire.

In arcade battles, this aircraft is particularly proficient at bombing bases, especially with a maxed reload crew skill. Since the Ki-49 can virtually turn on a dime, instead of having to line up longer bombing runs like heavy bombers you can "hover" over the base or airfield and attempt dive attacks. The 500 kg bomb is particularly useful here because you only have to drop one bomb instead of spamming multiple. It's also possible to use this same tactic against pillboxes or tanks. With fighter cover, a good reload time skill and good aim it's possible to destroy dozens of ground units.

Although unconventional, this aircraft is a fantastic weapon if you want to bait the enemy. Ideally, you would want to attract a higher flying enemy down to you and to get into a turnfight. This way, depending on the enemy aircraft you can outmanoeuvre and distract him while teammates fly down to finish him off.

The best way of grinding with this aircraft is to play cautiously and to use communication. As with any bomber, if you're caught alone or off guard you are as good as dead. Although not a sure tactic, having a fighter escort will boost RP gains drastically. This goes for both Arcade and Realistic battles. Generally, try to destroy as many targets as possible without wasting bombs. If done in a speedy fashion it is possible to drop multiple payloads in RB. The same goes for simulator battles. In Arcade battles, having a high reload speed and a fighter escort will allow for constant bombardment. If done correctly, flying the Ki-49 in all modes will net you large amounts of RP.

In realistic battles, your gunners might deter the stray fighter, but won't deter a horde of them. American fighters think you are the perfect target for .50 cal machine guns. What to do? Wait out the battle patiently. In all Realistic Battles, fights will get dragged to lower altitudes, and you can start climbing and head into the main are once you are high enough. One other strategy is to rush attack. Take out the 250 kg bombs and destroy four Pillboxes and then run back to base immediately to restock. This will allow for fighter support to come to you while you head back to base.

Nakajima Ki-49-II Donryu Army Bomber, type 100 model 2 (code name "Helen")

Prior to the outbreak of the War in the Pacific, the Japanese utilised the Ki-49 in China where it served well. It wasn't until the spring of 1942 that the Japanese military determined that the Ki-49 should be fitted with upgraded engines, namely the Nakajima Ha-109 radial piston engines which were rated at 1450 hp. Upgrading the engines, however, required slight modification of the engine nacelles to accommodate the newer engines even though they were roughly the same size as the original engines. Unfortunately, the oil cooler would not fit inside the nacelle along with the new engine and was instead mounted on the exterior of the nacelle. Other changes were also made to improve combat conditions of this aircraft: upgraded armour protection protecting the aircrew was installed along with self-sealing fuel tanks and a bombsight. The defensive armament remained similar to that of the Ki-49-I, however, the Type 89 machine guns were replaced with Type 98 7.92 mm machine guns (which were based on the Rheinmetall-Borsig MG.15). The normal bomb-carrying capacity of the aircraft was increased to 1,000 kg. A few short months later in August of 1942, this new version of the Donryu entered production under the designation Ki-49-IIa (model 2 Ko).

Quickly it was determined that the defensive machine guns were proven to be ineffective against Allied fighters and this required a new modification, which became the Ki-49-IIb (model 2 Otsu) implemented with stronger defensive weaponry. In the bow, stern, and ventral firing positions, the 7.92 mm Type 98 machine guns were replaced with 12.7 mm Ho-103 machine guns (the Type 1 Japanese version of the .50 cal Browning M2 machine guns). The two guns on the aircraft's sides were replaced with the original 7.7 mm Type 89 machine guns removed during the Ki-49-Ia upgrade. The bomb load remained unchanged at 1,000 kg. In later series, the Ki-49-IIb's common exhaust tube was replaced with several individual pipes. Even though the Ki-49-II bombers went through several revisions and upgrades, they were unable to completely replace the older models still in service. These bombers were used mainly in New Guinea, and China, and, in October of 1944, they were transferred to the Philippines where they actively participated in the Battle of Leyte Gulf. The Ki-49 was utilised as a jack-of-all-trades aircraft as she was used as both a day and a night bomber, long-range reconnaissance, transport, and anti-submarine patrols to name a few. Towards the end of the war, the Ki-49s were assigned to kamikaze units and modified for such action. Modifications for the kamikaze missions included stripping out all of the defensive armaments, the crew was reduced to two pilots and the bomb load was increased to 1,600 kg. Production of the Ki-49 ceased in December of 1944. In all its different variants, a total of 819 Ki-49s were constructed.

The first unit to receive Donryus was the 61st Sentai in China. An unknown amount of Ki-49s was involved in the Battle of Okinawa in 1945.

  • 95th Sentai, Papua New Guinea 1943
  • 61st Sentai, French Indochina 1944
  • 7th Sentai, 2nd Chutai 1944-45
  • 24th Sentai, 2nd Chutai Philippines 1944-45
  • 62nd Sentai 3rd Chutai Burma 1944

In the spring of 1942, it was decided that the Ki-49 should be fitted with new engines, the Nakajima Ha-109 radial piston engines, rated at 1450 hp. This required only a slight modification of the engine nacelles, as the new engine was a similar size to that of its predecessor. However, the oil cooler could not fit inside the nacelle along with the engine and was put outside, instead. Other changes were made to improve combat conditions: the armour protecting the airplane's crew was upgraded and self-sealing fuel tanks were installed, as well as a new bomb sight.

The defensive armament remained similar to that of the Ki-49-I, but the Type 89 machine guns were replaced with 7.92 mm Type 98 machine guns (which were based on the Rheinmetall-Borsig MG.15). Normal bomb carrying capacity was increased to 1,000 kg.

In August of 1942, the new version of the Donryu entered production, under the designation Ki-49-IIa (model 2Ko). However, the fighters' machine guns were soon proven to be ineffective against Allied fighters, so a new modification, the Ki-49-IIb (model 2Otsu) was designed with stronger defensive weaponry. In the bow, stern, and lower firing locations, the 7.92 mm Type 98 machine guns were replaced with 12.7 mm Ho-103 machine guns (the Type 1 Japanese version of the .50 cal Browning M2). The two guns on the aircraft's sides were replaced with the original 7.7 mm Type 89 machine guns. The bomb load remained unchanged.

In later series, the Ki-49-IIb's common exhaust was replaced with several separate pipes.

The Ki-49-II bombers were unable to completely replace the older models in service. They were used mainly in New Guinea and China, and, in October of 1944, they took active participation in the Battle of Leyte.

The Ki-49 was used as both a day and a night bomber as well as for long-range reconnaissance, transport, and anti-submarine patrols. Towards the end of the war, they were used in kamikaze units. For kamikaze missions, the Ki-49 was stripped of all defensive armaments, the crew was reduced to two pilots, and the bomb load was increased to 1,600 kg.

Production of the Ki-49 ceased in December of 1944. In all, 819 Ki-49s were constructed, including all variants.
