Type 30-1 (30 mm)

Description

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

• J-6A
• J-7II
• J-7E

General info

The Type 30-1 fires 30 mm rounds at 1,000 RPM, with a muzzle velocity of 800 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.

• Default: HEF-I · HEFI-T · APHE

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

Pros:

• High muzzle velocity (800 m/s)
• Excellent damage capabilities
• Good potential for multirole use, with APHE able to penetrate up to 41 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

Cons:

• Tracer rounds found in every belt choice
• Extremely poor ammunition reserves punish poor trigger discipline

History

Type 30-1 was the licensed version of the Soviet NR-30 cannon found on their mid-1950s to late 1960s interceptors; the NR-30 was imported into Mainland China alongside the knock-down kits of MiG-19. Prototypes were built in 1957 and sample guns were tested in 1959, which passed state certifications and was installed on multiple PLAAF jets from J-6 to J-8I series. The gun then received an upgrade for better maintenance and efficiency in the 1980s.

The gun is still in PLAAF service on the remaining J-7E and Gs, as well as foreign customers who are still using F-7 at present.
