S-68 (57 mm)
Contents
Description
The S-68 (C-68 in Russian), based on AZP S-60 57 mm anti-aircraft gun, is the twin-barrel variant of the latter; serving as the main weapon of ZSU-57-2.
An attempt to built field AA gun with the chassis of a T-54, the twin-barrel S-68 provided sufficient rate of fire while having very devastating firepower at close-range brawls; while it might not do well at its intended purpose of anti-aircraft operations, a solid hit on slow aircrafts can prove deadly with its caliber and explosive fillers.

General info
Available shells
- Default: HE* · APCBC - 50% of this belt are useless against tanks or planes. However, against other SPAA this belt can reliably take out crew, armament, ammo and engine. Having one belt in reserve does not hurt.
- BR-281: APCBC - For use against ground vehicles. With around 150 mm of penetration at point blank, this belt can go through side armour and take out lightly armoured targets. Actual MBTs can typically resist it from the front. It does not contain much explosive filler per round, but since the WZ305 has two cannons (each with a clip of 4 rounds) multiple penetrations have a high chance of knocking out the target.
- OR-281U: HE* - For use against planes. One or two hits usually get the job done. However, heavy armoured attackers and bombers may require several hits.
- BR-281U: APCBC · HE* - For use against ground vehicles. A solid shot projectile, it currently has the same penetration as the ordinary BR-281 APCBC and there is thus no real reason to use it.

Comparison with analogues
WA318- it's Chinese cousin, while sharing most of same traits, S-68 has a better traverse speed; but WA318 has access to HE-VT shell which vastly boost its anti-aircraft capabilities.
Usage in battles
At its tier, twin-barrel 57 mm gun stands out among vehicles at similar tiers. Thanks to its high rate of fire and penetration, for lightly-armored vehicles or those who showed their sides, this gun is the nightmare for them as the APHE/APCBC shells on it works fantastically against armored targets, 8 shots at very short time can certainly knock down most of the enemies it might ever face (aside from Maus or the rare E-100).
While S-68 doesn't do really well in its intended purpose: anti-aircraft operations (it was intended to be guided by radar and rangefinders), thanks to the sheer caliber and enough explosive filler, a solid hit on the target certainly means severe or lethal damage against them; at higher tier where helicopters are present, when aimed properly, it can score a surprise kill even at 3-4 km away.
Pros and cons
Pros:
- Devastating in brawling or flanking
- Sufficient rate of fire and ammo pool
- High explosive content
- Straight ballistic
Cons:
- Requires a solid hit on aerial targets
- Lightly-protected
- Huge profile
History
During the Great Patriotic War (Eastern Front of WWII), Soviets soon realized that their current anti-aircraft gun inventory was insufficient to handle targets at higher altitudes (both 25 mm and 37 mm wouldn't travel very far before being ineffective; larger caliber guns requires long reload time); it was deemed that a new anti-aircraft gun must be made to cover the mid-caliber range.
While they have acquired examples of Germans' 5 cm FlaK41, Soviets also acquired a prototype gun dubbed 5,5 cm Gerät 58; these became the basis of a later prototype gun with a 57 mm caliber in 1946, after years of field tests, the gun was certificated for service in early 1950s as the AZP S-60. While these guns has radar and rangefinder for target tracking, in the era of supersonic jets, S-60 were soon phrased out in favor for SAMs; although later experiences from Vietnam showed that it was still effective against low flyer and should be kept as a supplement for the underperforming SAMs at the era, where ground clutters severely affect its tracking capabilities.
Aside from the base model S-60, there were navalized version AK-725 and ZIF-72, as well as S-68 on ZSU-57-2; although most of the S-60s survived today are seen in different warfare overseas, sometimes even mounted onto a dump-truck as improvise platform, the Russian Ground Forces built a new 57 mm unmanned weapon system based on S-60, known as AU-220M and was first seen as on an Armata Universal Platform in late 2010s.
