General info

Flight performance

Describe how the aircraft behaves in the air. Speed, manoeuvrability, acceleration and allowable loads - these are the most important characteristics of the vehicle.

Usage in battles

Describe the tactics of playing in an aircraft, the features of using aircraft 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

Summarise 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 - use substitutions with softer forms such as "inadequate" and "effective".

Pros:

• Excellent speed
• Good climb rate
• Decent maneuverability for a bomber
• Possesses offensive armament, one centrally mounted ShKAS (7.62mm) gun, coupling great accuracy with a superb rate of fire
• Great cockpit visibility (SB)

Cons:

• Very poor bomb load, will struggle at taking out armored targets (medium tanks, pillboxes, etc.), ineffective at base bombing
• Poor energy retention, bleeds speed in turns
• Vulnerable engines tend to overheat quickly at 100% throttle
• Rear gunner cannot aim below 0°, rendering you harmless to any enemies under the plane
• As with the Yak-2, pilot has little protection and can be knocked out easily

History

Describe the history of the creation and combat usage of the aircraft in more detail than in the introduction. If the historical reference turns out to be too long, take it to a separate article, taking a link to the article about the vehicle and adding a block "/ History" (example: https://wiki.warthunder.com/(Vehicle-name)/History) and add a link to it here using the main template. Be sure to reference text and sources by using <ref></ref>, as well as adding them at the end of the article with <references />. This section may also include the vehicle's dev blog entry (if applicable) and the in-game encyclopedia description (under === In-game description ===, also if applicable).

Media

Excellent additions to the article would be video guides, screenshots from the game, and photos.
