General info

Tell us about the tactical and technical characteristics of the cannon or machine gun.

Available ammunition

• Default: AP-I · FI-T
• Armoured targets: FI-T · AP-I · AP-I · AP-I
• Air targets: FI-T · FI-T · FI-T · AP-I
• Stealth: AP-I
• Default (turret): AP-I · FI-T
• Universal (turret): AP-I · AP-I · AP-I · FI-T
• FI-T (turret): FI-T · FI-T · FI-T

It is possible to achieve penetration American MBTs' roofs (Abrams, MBT-70) with the AP-I round, although this task can prove to be difficult.

A FI-T hitting the inner wing or central fuselage will act like a "mini flak shell" and can cause fuel leaks, oil leaks, engine damage, and inner wing damage.

Comparison with analogues

Give a comparative description of cannons/machine guns that have firepower equal to this weapon.

Usage in battles

This weapon makes for a fairly dangerous encounter, whether for you or your enemy. The slightly above average rate of fire of 900 RPM allows for long-range tap firing or long bursts. The largest issue is that despite the large calibre, it lacks enough punch to ensure each hit will cripple the target, yet it still tends to come with a sparse supply of ammunition. Trigger happy pilots beware! Precise aim is required!

Pros and cons

Pros:

• Higher fire rate than predecessor (NS-23 found on Mig-15 standard)
• Decent damage per short burst of shells (about four or more shells, a burst of three can work about 50% of the time)
• High fire rate for a gun of this calibre

Cons:

• Low velocity
• One or two shells usually won't cause a critical or destroy an enemy (two may impact performance for a follow-up)
• Occasional sparks
• Generally low ammunition supply

History

Examine the history of the creation and combat usage of the weapon 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 If the historical reference turns out to be too long, take it to a separate article, taking a link to the article about the weapon and adding a block "/History" (example: https://wiki.warthunder.com/(Weapon-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 />.

Media

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