Armaments
Suspended armament
The Ki-21-I hei can be outfitted with the following ordnance:
- 20 x 50 kg Army Type 94 GPHE bombs (1,000 kg total)
- 10 x 100 kg Army Type 94 GPHE bombs (1,000 kg total)
- 4 x 250 kg Army Type 92 GPHE bombs (1,000 kg total)
- 2 x 500 kg Army Type 92 GPHE bombs (1,000 kg total)
Defensive armament
The Ki-21-I hei is defended by:
- 1 x 7.7 mm Type 89 'special' army machine gun x2, dorsal turret (450 rpg = 900 total)
- 7 x 7.7 mm Te-1 army machine gun (483 rpg = 3381 total)
Usage in battles
The main difference between the Ki-21-Ia and this Ki-21-Ic is armament, 2 x Te-1's compared to 7 x Te-1's which are simply the best 7.7 mm's Japan can offer, with a 950 rpm firerate, 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 1000 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.
Pros and cons
Pros:
- Very manoeuvrable
- Extensive bombload for a rank I Japanese bomber
- Decent cruising speed
- Durable, can take some hits
- Above average defensive armament for its BR
- Internal payload
Cons:
- Loses effectiveness with altitude
- No armour
- Falls quickly when attacked by multiple foes
- Head on attacks are usually fatal because of lack of protection for the pilots
- Gunners can be knocked out easily
History
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).
Media
Excellent additions to the article would be video guides, screenshots from the game, and photos.
