| − | + | The '''{{Specs|name}}''' was a Japanese medium bomber developed in late 1930s. The development of the Ki-49 began after experience from combat with Ki-21 showed that the bomber would be unable to conduct daylight bombing missions unescorted. To remedy this issue, heavy defensive armament as well as armour was installed. The Ki-49-IIa featured more powerful Ha-109 engines as opposed to the Ha-41 engines used previously, self-sealing fuel tanks, and an improved armour scheme. | |

The Ki-49's role is a low-altitude medium 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. The defensive armament coupled with the armour also makes repelling attackers easier, especially with the dorsal 20 mm cannon. |

| + | 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. | ||
| + | |||
| + | 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. | ||

| − | This aircraft has the ability to hold up to | + | 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 and 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 loadout 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 or mini bases. Use the 500 kg bomb to destroy targets like carriers. |
| − | In arcade battles, this aircraft is particularly proficient at bombing bases, especially with a maxed reload crew skill.

Since you 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 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. |
| − | 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. 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 found 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. | + | If attacked by fighters, it is important to remember and recognize the Ki-49's turning capabilities.

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 turn fight. This way, depending on the enemy aircraft you can outmanoeuvre and distract him while teammates fly down to finish him off. Also if the enemy aircraft attacks from above, the 20 mm Ho-1 cannon can do a lot of damage. | Although unconventional, this aircraft is a fantastic weapon if you want to bait the enemy.

| − | 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.

In the bow, stern, and ventral firing positions, the 7.92 mm Type 98 machine guns were replaced with Ho-103 12.7 mm machine guns (the Type 1 Japanese version of the Browning M2 .50 calibre 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. |

Description
The Ki-49-IIa Donryu was a Japanese medium bomber developed in late 1930s. The development of the Ki-49 began after experience from combat with Ki-21 showed that the bomber would be unable to conduct daylight bombing missions unescorted. To remedy this issue, heavy defensive armament as well as armour was installed. The Ki-49-IIa featured more powerful Ha-109 engines as opposed to the Ha-41 engines used previously, self-sealing fuel tanks, and an improved armour scheme.
The Ki-49-IIa 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 medium 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. The defensive armament coupled with the armour also makes repelling attackers easier, especially with the dorsal 20 mm cannon.

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.
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.
Armaments
Suspended armament
The Ki-49-IIa 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)

- 1 x 7.7 mm Type 89 machine gun, nose turret (450 rpg)
- 1 x 7.7 mm Type 89 machine gun, ventral turret (450 rpg)
- 1 x 7.7 mm Type 89 machine gun, 2 x beam turrets (450 rpg = 900 total)
- 1 x 7.7 mm Type 89 machine gun, tail turret (900 rpg)
Usage in battles
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 and 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 loadout 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 or mini bases. Use the 500 kg bomb to destroy targets like carriers.
In arcade battles, this aircraft is particularly proficient at bombing bases, especially with a maxed reload crew skill. Since you 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 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.
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. 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 found 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.
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 turn fight. This way, depending on the enemy aircraft you can outmanoeuvre and distract him while teammates fly down to finish him off. Also if the enemy aircraft attacks from above, the 20 mm Ho-1 cannon can do a lot of damage.

History
- Nakajima Ki-49-II Donryu Army Bomber, type 100 model 2a (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 Ho-103 12.7 mm machine guns (the Type 1 Japanese version of the Browning M2 .50 calibre 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
