Survivability and armour
Examine the survivability of the aircraft. Note how vulnerable the structure is and how secure the pilot is, whether the fuel tanks are armoured, etc. Describe the armour, if there is any, and also mention the vulnerability of other critical aircraft systems.
Describe the aircraft's suspended armament: additional cannons under the wings, bombs, rockets and torpedoes. This section is especially important for bombers and attackers. If there is no suspended weaponry remove this subsection.
Defensive armament with turret machine guns or cannons, crewed by gunners. Examine the number of gunners and what belts or drums are better to use. If defensive weaponry is not available remove this subsection.
Usage in battles
Describe the tactics of playing in an aircraft, the features of using vehicles in a team and advice on tactics. Refrain from creating a "guide" - do not impose a single point of view, but instead, give the reader food for thought. Examine the most dangerous enemies and give recommendations on fighting them. If necessary, note the specifics of the game in different modes (AB, RB, SB).

Pros and cons
Summarize and briefly evaluate the vehicle in terms of its characteristics and combat effectiveness. Mark its pros and cons in the bulleted list. Try not to use more than 6 points for each of the characteristics. Avoid using categorical definitions such as "bad", "good" and the like - they can be substituted with softer forms such as "inadequate" and "effective".
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.
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-I Otsu and finally Ki-21-I Hei.
Excellent additions to the article would be video guides, screenshots from the game, and photos.
