The '''Ki-21-Ic''', designated as the '''Type 97 Heavy Bomber ({{Annotation|九七式重爆撃機|Kyū Nana-Shiki Jū-Bakugekiki}})''', was the third variant of the Ki-21 production series. Following the improvements from the Ki-21-Ib to the control surfaces, it also came with more machine guns and larger fuel tanks increasing its range.

The '''{{Specs|name}}''' was introduced during [[Update 1.65 "Way of the Samurai"]] as a reward vehicle for the [[wt:en/news/4416-special-war-thunder-winter-holiday-en|2016 "Winter Holiday"]] event. It was later made available as a battle trophy vehicle in the Warbond shop from the [[Battle Pass: Season I, 75th Anniversary of the Great Victory]] until the end of the [[Battle Pass: Season IV, "Fearless Voltigeur"]]. While on the surface, the Ki-21-Ic looks like another Ki-21 with a name change, the amount of machine guns was tripled, with two MGs added on each side of the plane and a remote-controlled gun directly in the tail which will destroy any plane directly on the six of the Ki-21.

The main difference between the [[Ki-21-Ia]] and this Ki-21-Ic is armament, 2 x Te-1s compared to 7 x Te-1s which are simply the best 7.7 mm Japan can offer, with a rate of fire of  950 rpm, API - IT belts in the universal belt which do a lot of damage and covers the whole plane.
 +
 
 +
If attacked by fighters, it is important to remember and recognize the Ki-21's turning capabilities. It is actually possible to win lateral turn fights against fighters with this aircraft as she is one of the most manoeuvrable bombers if not the most manoeuvrable bomber in game.
 +
 
 +
This aircraft has the ability to hold up to 1,000 kg of bombs in several different variations: 20 x 50 kg, 10 x 100 kg, 4x 250 kg, and 2 x 500 kg. Use the 20 x 50 kg or 10 x 100 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 that have an abundance of non-moving targets (light pillboxes) or lightly armoured targets (armoured cars or AA trucks for example). Use either of the 4 x 250 kg or 2 x 500 kg payload to destroy heavier targets such as medium tanks, pillboxes, destroyers, and cargo ships.
 +
 
 +
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 out manoeuvre and distract him while teammates fly down to finish him off.

'''About the plane'''
 +
 
 +
The first-generation Ki-21, or Ki-21-I Kô (Model IA), was a full-metal monoplane bomber. Its cantilever wing was implanted in the middle position. The crew positions were largely glazed, providing good visibility for the five crewmen. The landing gear included two train legs fitting almost completely into the two engine nacelles, plus a non-retractable tailwheel. The two engines were Nakajima Ha-5 Kai, with unit power of 850 hp (1,000 hp at takeoff), each driving a three-bladed metal propeller with variable pitch. Serial production really began in 1938 in the Mitsubishi and Nakajima factories.
 +
 
 +
'''Combat usage'''
 +
 
 +
The first available aircraft were engaged in China during Summer 1938, where they were well-received by the crews of the army. The first reports on the commitment of these planes enabled Mitsubishi to make changes, particularly in terms of armaments. This led to the development of new versions, such as Ki-21-Ib (乙, otsu) and finally Ki-21-Ic (丙, hei).

The Ki-21-Ic, designated as the Type 97 Heavy Bomber (九七式重爆撃機), was the third variant of the Ki-21 production series. Following the improvements from the Ki-21-Ib to the control surfaces, it also came with more machine guns and larger fuel tanks increasing its range.

The Ki-21-I hei was introduced during Update 1.65 "Way of the Samurai" as a reward vehicle for the 2016 "Winter Holiday" event. It was later made available as a battle trophy vehicle in the Warbond shop from the Battle Pass: Season I, 75th Anniversary of the Great Victory until the end of the Battle Pass: Season IV, "Fearless Voltigeur". While on the surface, the Ki-21-Ic looks like another Ki-21 with a name change, the amount of machine guns was tripled, with two MGs added on each side of the plane and a remote-controlled gun directly in the tail which will destroy any plane directly on the six of the Ki-21.

About the plane

The first-generation Ki-21, or Ki-21-I Kô (Model IA), was a full-metal monoplane bomber. Its cantilever wing was implanted in the middle position. The crew positions were largely glazed, providing good visibility for the five crewmen. The landing gear included two train legs fitting almost completely into the two engine nacelles, plus a non-retractable tailwheel. The two engines were Nakajima Ha-5 Kai, with unit power of 850 hp (1,000 hp at takeoff), each driving a three-bladed metal propeller with variable pitch. Serial production really began in 1938 in the Mitsubishi and Nakajima factories.

Combat usage

The first available aircraft were engaged in China during Summer 1938, where they were well-received by the crews of the army. The first reports on the commitment of these planes enabled Mitsubishi to make changes, particularly in terms of armaments. This led to the development of new versions, such as Ki-21-Ib (乙, otsu) and finally Ki-21-Ic (丙, hei).
