== Usage in battles ==
''Describe the tactics of playing in the 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 ===
The best way to play this plane is to zoom climb up to 2.5k-3k meters and drop on a low and slow jet. Staying on someones six is very easy with this plane and its defensive flying is pretty effective.

'''Pros:'''
*Good turn rate compared to other jets
*Decent armament
*Good low speed performance with flaps

'''Cons:'''
*Slow for a jet
*Climb might be the worst in its br
*Bad energy retention

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 If the historical reference turns out to be too long, take it to a separate article, taking a link to the article about the vehicle and adding a block "/History" (example: 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

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