PG87 (25 mm)

Description

The PG87 25 mm anti-aircraft gun (PG87式25毫米双管高射炮) is the enlarged version of the previous PG85 23 mm anti-aircraft gun, the reverse-engineered version of Soviet's ZU-23-2.

Vehicles equipped with this weapon

• PGZ04A
• ZSD63/PG87

General info

The overall design of PG87 is very similar to its reverse-engineered Soviet counterpart, ZU-23-2 while being larger and used 25x183 mmB cartridge as its selected ammunition; giving it a straight ballistic and higher velocity (1050 ms;970-980 ms) than ZU-23-2, comparable to NATO's Oerlikon KBA 25 mm autocannon.

Available ammunition

• Default: AP-T · FI-T*
• Type 87 HE: FI-T*
• Type 87 AP: AP-T

Penetration statistics
Belt	Penetration @ 0° Angle of Attack (mm)
	10 m	100 m	500 m	1,000 m	1,500 m	2,000 m
Default	63	60	47	35	26	19
Type 87 HE	2	2	2	2	2	2
Type 87 AP	63	60	47	35	26	19

Comparison with analogues

Thanks to the overall larger cartridge of 25 mm ammunition, PG87 has a straighter trajectory compare to Soviet's ZU-23-2 and its quad-mount AZP-23 found on ZSU-23-4, although the lesser choice on ammunition might seem disappointing at first glance; the default penetration from Type 87 AP-T round can penetrates most NATO vehicles' sides, its RoF also helps it gunning down its targets.

While shared similar traits to Oerlikon KBA, PG87 doesn't come with any type of APDS round (however, ZPT90 based on PG87 does), which could be a drawback against vehicles with thicker sides.

Usage in battles

At first glance, the gun does looks like a ZU-23-2 from Soviet Union, but its 25 mm caliber become the major difference between these two guns; it was aimed to be comparable to NATO's Oerlikon KBA, thus having a higher velocity and higher penetration than ZU-23-2. The default belt itself has a balanced arrangement of shells of AP-T and FI-T, more than enough to gun down even the toughest aircrafts at their tiers if they are careless enough to enter its kill-zone.

While overall being better than its Soviet counterpart, there is a major drawback for PG87: its reload rate. For the towed gun version found on ZSD63, it takes up to 35 seconds to reload, which is very fatal in heated fight, so do conserve ammo and wait until the target is within 800 m- the target will have lesser chance to escape the short burst of 25 mm shells; it also doesn't compatible with ZPT90's 25 mm APDS shell found on IFVs, thus leading to a lower penetration than Oerlikon KBA (M791 with 91 mm penetration at point-blank); while Type 87 AP is still enough to gun down tanks with thinner sides, but it struggles to penetrate Soviet tanks with thicker sides.

Pros and cons

Pros:

• Higher velocity and penetration than ZU-23-2
• High rate of fire
• Type 87 FI-T round has high explosive mass

Cons:

• Small ammo pool for the towed version

• Slow reload time (takes up to 35 seconds to reload for the towed version)
• Type 87 AP-T round still struggles to penetrate tanks with over 70 mm side armor

History

After the certification of the reverse-engineered PG85 23 mm anti-aircraft gun in 1985, an upgraded version of this gun with 25 mm caliber in view of NATO's Oerlikon KBA, dubbed PG87 was then passed certification in 1987 with new IR tracking gunsight, serving as an enhanced version of PG85 and was used as field tow AA gun or as the composition of the later PGZ95/04A SPAAG.
