PG99-35-2 (35 mm)

Description

The 35 mm PG99-35-2 (PG99式35毫米防空炮) is a Chinese anti-aircraft gun. It is the domestic upgraded version based of the 35 mm Oerlikon KDA GDF-002.

Vehicles equipped with this weapon

• PGZ09

General info

The PG99-35-2 has a high muzzle velocity and high penetration thanks to the APDS rounds. Its rate of fire is adequate and identical to other SPAAGs equipped with a similar calibre.

Available ammunition

• Default: API-T · HEI-T*
• DKG01A: HEI-T* · HEI-T* · HEI-T* · API-T
• DKP01A: API-T · API-T · API-T · HEI-T*
• DM23: APDS · APDS · APDS · APDS

Note: the shells are identical to NATO counterparts.

Comparison with analogues

The PG99-35-2 shares the same design as the Swiss Oerlikon KDA cannon, which was licensed back in the late 1980s. Therefore, it has the same performance as the Oerlikon KDA.

Since the gun is based on Oerlikon KDA found on different NATO SPAAGs, they shared the same traits and the selection of ammunition is identical as well, thus having the same high velocity and penetration with APDS; while having a lower rate of fire than AZP-23, M163 and Oerlikon KBA from the same company.

Usage in battles

Since the gun is identical to any other 35 mm Oerlikon KDA, its straight ballistics and high explosive mass from DKG01A means it can shoot down aircraft at its tiers and the penetration on DKP01A and DM23 is enough to gun down MBTs at similar tiers; PG99-35-2 however has a lower ammo count than his NATO counterparts so the overall firing time is shorter, it is not a good idea to be trigger-happy with PG99-35-2; the mere -2° depression angle can be embarrassing during close-quarter fights or complicated terrain.

Pros and cons

Pros:

• High explosive mass
• Sufficient rate of fire with straight ballistic
• APDS available for gunning down heavier targets

Cons:

• Lower ammo count than NATO counterparts
• Limited -2° depression angle

History

During the late 1980s, after attempts to make their own AA guns to replace the obsolete Soviet 37 mm, the PLA sought instead to purchase the renowned Swiss Oerlikon 35 mm GDF-002 cannon. In 1987, a deal was made and examples were imported along with the Skyguard system, and in 1990, China got a license for domestic production under the name PG90. When the later arms embargo in the 1990s stopped additional importation, Chinese-made domestic upgrades resulted in the PG99, which is said to be on-par with the GDF-003.

PG99-35-2 is usually seen as the field tow gun, while the later PGZ09 gives this gun mobility and it serves as one of the cornerstone of close range air-defense network, gunning down aircraft with conventional shells or cruise missiles with AHEAD programmable shells.
