  • 2 x 12.7 mm Akan m/39A machine guns, nose-mounted (350 rpg = 750 total)
  • 2 x 12.7 mm Akan m/39A machine guns, wing-mounted (325 rpg = 650 total)

Usage in battles

One way to operate this aircraft is to zoom climb up to about 2.5k-3k meters and then drop on a low and slow jet. Staying on someones tail is very easy with this plane and its defensive flying is quite effective.

Pros and cons

Pros:

  • Good turn rate compared to other jets
  • Decent armament
  • Good low-speed performance when utilising flaps

Cons:

  • Slow for a jet
  • Climb might be the worst in comparison to others in its battle rating
  • 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 If the historical reference turns out to be too long, take it to a separate article, taking a link to the article about the vehicle and adding a block "/History" (example: 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.
