T-34/76 STZ (1942)

Description

T-34 with 76 mm F-34 main gun built at Stalingrad Tractor Factory (STZ), Summer 1942, with welded turret that was shipped from factory 264. The main feature of STZ tanks built in this timeframe is the turret with cut bottom-front edges, straight gun mantlet and cast wheels with internal dampeners.

The production at STZ continued until the very last moment: it stopped completely and the remaining workers were evacuated on October 5th, 1942, when the German forces almost reached the factory buildings.

Modifications

High-Explosive Shells
OF-350

Good against soft, unarmoured or lightly armoured targets.

Mass 6.2 kg, explosives mass 710 g.
Direct hit armour penetration 20 mm, effective damage distance for light vehicles 3 m.

When fired from a F-34 / ZiS-5 gun:
Muzzle velocity: 680 m/s.
500 m: velocity: 616 m/s, drop -3.0 m.
1000 m: velocity: 558 m/s, drop -12.5 m.
2000 m: velocity: 468 m/s, drop -56.7 m.

Armour Piercing Shells
BR-350BSP

Solid armour piercing shells without explosive filling.
Good against spaced armour plates, but cause less damage inside a target than more advanced APHE.

Mass: 6.6 kg.

When fired from a F-34 / ZiS-5 gun:
Muzzle velocity 660 m/s, armour penetration at point blank range 87 mm.
500 m: armour penetration 73 mm, velocity 585 m/s, drop -3.2 m.
1000 m: armour penetration 62 mm, velocity 524 m/s, drop -13.6 m.
2000 m: armour penetration 47 mm, velocity 429 m/s, drop -63.5 m.

Armour Piercing High Explosive Shells
BR-350B

Shells armed with bursting charge warhead.
Good against armoured targets. In case of penetration do more damage inside the target than solid AP shells, but HE filling can detonate prematurely (for instance, when used against spaced armour plates).

Mass 6.5 kg, explosives mass 119 g.

When fired from a F-34 / ZiS-5 gun:
Muzzle velocity 660 m/s, armour penetration at point blank range 86 mm.
500 m: armour penetration 72 mm, velocity 584 m/s, drop -3.2 m.
1000 m: armour penetration 61 mm, velocity 522 m/s, drop -13.6 m.
2000 m: armour penetration 46 mm, velocity 427 m/s, drop -64.0 m.

Sub-Caliber Armour Piercing Shells
BR-354P

Shells armed with sub-caliber armour-piercing projectile.

Good against heavily armoured targets at short ranges: being much lighter than ordinary rounds, they have much higher muzzle velocity and armour penetration at close distances. However, because of the lower mass their velocity quickly diminishes with distance and they are worse than ordinary rounds at higher distances.

The penetrator is held in the barrel by a spool looking sabot. While reducing the round mass for increased muzzle velocity, this makes it lose velocity even more quickly because of the air drag.

Mass: 3.02 kg, penetrator calibre 28 mm.

When fired from a F-34 / ZiS-5 gun:
Muzzle velocity 950 m/s, armour penetration at point blank range 129 mm.
500 m: armour penetration 90 mm, velocity 741 m/s, drop -1.7 m.
1000 m: armour penetration 60 mm, velocity: 558 m/s, drop -8.0 m.
2000 m: armour penetration 24 mm, velocity: 295 m/s, drop -53.3 m.
