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".
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 If the historical reference turns out to be too big, take it to a separate article, taking a link to the article about the vehicle and adding a block "/ History" (example: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>, as well as adding them at the end of the article.
Excellent additions to the article would be video guides, screenshots from the game, and photos.
Links to the articles on the War Thunder Wiki that you think will be useful for the reader, for example:
- reference to the series of the aircraft;
- links to approximate analogues of other nations and research trees.
Paste links to sources and external resources, such as:
- topic on the official game forum;
- encyclopedia page on the aircraft;
- other literature.
