Armaments

Offensive armament

Weapon 14 x 12.7 mm LKk/42 machine gun
Ammunition1 300 rounds
Fire rate1 100 shots/min
Main article: LKk/42 (12.7 mm)

The B-239 (Sweden) is armed with:

  • 2 x 12.7 mm LKk/42 machine guns, nose-mounted (250 rpg = 500 total)
  • 2 x 12.7 mm LKk/42 machine guns, wing-mounted (400 rpg = 800 total)

Usage in battles

You are pretty manoeuvrable and can win a dogfight against most enemies, the exception being Spitfires and Japanese single engine fighters. Be wary of you poor energy retention though, this leads you to gain an advantage in the first couple of turns in your dogfight but you should try to avoid longer fights, by any means. You can use flaps to get the maximal turn rate possible. You can also climb at the beginning of a match, get to 3-4 km while climbing at 220 km/h IAS. Once you see enemy fighters, level out and stay above 280-300 km/h, this ensures you can at least follow one or two turns, to get a good shot in. If this fails, dive away and reposition.

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".

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 If the historical reference turns out to be too long, take it to a separate article, taking a link to the article about the vehicle and adding a block "/History" (example: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.
