Type 30-1 (30 mm)
The 30 mm Type 30-1 is the Chinese variant of the Soviet NR-30 cannon, mounted on the J-6s and J-7s. As such, the weapon's performance is identical to the Soviet version.
Vehicles equipped with this weapon
The Type 30-1 fires 30 mm rounds at 1,000 RPM, with a muzzle velocity of 780 m/s. Thanks to the calibre of the gun, as well as the explosive mass of the HEF-I shells, the Type 30-1 is very capable of destroying opponents in only one to two direct hits, especially to the wings. However, aircraft equipped with the Type 30-1 only hold reserves of 70 rounds per gun, which combines with the rate-of-fire of 1,000 RPM to punish players with a poor aim and lacklustre trigger discipline. These factors cause the Type 30-1 to demand moderately high skill to use but rewards successful use with reliable critical damage or even swift target destructions.

Comparison with analogues
Though firing a fair amount slower, the Type 30-1's closest comparisons are the British ADEN and French DEFA cannons, both 30 mm cannons with similar ballistics and destructive capabilities. Both guns are very capable of destroying opponents in one to two hits, though planes equipped with ADENs and DEFAs tend to have the advantage of a far larger ammo supply; where the J-6A only carries 140 rounds for 2 Type 30-1s, the Hunter F.1 carries 600 shells for four ADEN cannons; the difference in endurance is clear.
Usage in battles
The Type 30-1s finds its use well in high-angle deflection shots, with great muzzle velocity allowing it to easily hit opponents who are crossing the user's nose. Try to position your fighter so that enemies will fly past your nose, even if only for a brief moment, as the Type 30-1's destructive power causes even brief exposure to end in a lethal encounter with their rounds.
Pros and cons
- High muzzle velocity (780 m/s)
- Excellent damage capabilities
- Good potential for multirole use, with APHE able to penetrate up to 60 mm of RHA
- Burst mass, per gun, exceeding that of even ADENs and DEFAs
- Relatively high rate-of-fire (1,000 RPM)
- Notably accurate out to long ranges, even when not upgraded
- Tracer rounds found in every belt choice
- Extremely poor ammunition reserves punish poor trigger discipline
