Type 23-2K (23 mm)

Jump to: navigation, search


The 23 mm Type 23-2K is a Chinese autocannon fitted to the Q-5s, replacing the 30 mm from the J-6. The weapon in-game is similar to the Soviet NR-23 and has sufficient firepower to destroy careless aerial targets if the shots land on the target.

General info

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

Available ammunition

  • Default: AP-I · HEF-I
  • Armoured targets: HEF-I · AP-I · AP-I · AP-I
  • Air targets: HEF-I · HEF-I · HEF-I · AP-I
  • Stealth: AP-I

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

A HEF-I 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 1150 RPM allows for long-range tap firing or long bursts. The largest issue is that despite the large calibre, it could be frustrating with its lack of enough punch to ensure each hit will cripple the target and lower velocity than its Soviet ancestor, yet it still tends to come with a sparse supply of ammunition. Trigger-happy pilots beware! Precise aim is required!

Pros and cons


  • Decent damage per short burst of shells
  • High fire rate for a gun of this calibre


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


While designing China's first ground attacker, the Nanchang Aircraft Corporation attempted to put 2 NR-30 (Type 30-1) cannons into the Xiongying 302 (Soaring Eagle 302) prototype (later known as Q-5) in 1965, but the ground and aerial tests showed that 2 large-calibre cannons placed in the nose of a jet attacker wasn't a good idea - as the fumes from the 30 mm autocannons caused engine stalls similar to that of the MiG-9, forcing chief designer Lu Xiaopeng (陆孝彭) to move its cannons to the root of the wing and downgrade to 23 mm NR-23 (Type 23-1) cannons; but while the smaller calibre and repositioned guns reduced fume-caused stalling of engines, the NR-23 still could cause engine stalling.

Thus, in the later prototypes and the pre-production run of the Q-5, the Nanchang Aircraft Corporation changed the cannons to the shorter and muzzle-braked Type 23-2K cannons, reducing some of its velocity while retaining the ammo count, firepower, and preventing engine stalls caused by the aforementioned muzzle fumes.

Currently, these cannons have been decommissioned by the PLAAF and only the remaining foreign users of the A-5 still use this gun.


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