Mobility

The SU-57B is sluggish at backwards speed and you will have a hard time countering an opponent behind you. Your best bet is to flee when spotted. Fortunately thanks to its great speed (43 km/h maximum) it can flee quite easily.

Armaments

Main armament

It's pretty good reload speed (6.5 seconds) allows this tank to shoot with efficiency, however, with 72 rounds of ammunition, the SU-57B has much more ammo than the ZIS-30, allowing it to shoot freely without restriction. However, keep in mind the 6.5 seconds initial reload time can be quite long when facing an opponent at close range.

Usage in the battles

The SU-57B is purely a tank hunter. With its 57mm ZIS-4 gun, and at a BR of 3,3 it can easily pierce almost any opponent in the game. Because of its weak armour, it was not capable of engaging too close and had to stay at a medium to long range.

Its APHEBC initial ammunition is effective at piercing enemy armour, but the next ammo modification is even better with the APHE round (BR-271K).

It also features a HE round that can be unlocked later, but it is preferable to stick with BR-271 or BR-217K rounds as they offer up to 142 mm of penetration which is excellent for its use and BR.

The SU-57B is best played as a sniper, preferably taking advantage of its very low profile (still not as good as the ASU-57 but almost). It excels at shooting from high vantage points or from the sides but must be repositioned after each shot to avoid retaliation fire.

With only 25 mm frontal armour at best and 16mm on the side and virtually none on the rear, a single shot would be fatal and leave the crew disabled at best. It is even susceptible to Heavy MG fire from the sides and rear.

Defensive tactics

The SU-57B is quite slow and not good at turning. It is imperative to chose a good spot where you can extract from in case you spot an enemy tank coming your way.Repositioning again is the key to survivability. When discovered you will have a hard time fleeing, so don't count on it.

Use bushes, trees and hills as cover , and use the "shoot and boom" tactic: get out of your cover, shoot, get back to cover , always hidden.

Pros and cons

Pros:

• Great forward speed
• Great 57mm ZIS-4 main gun
• Very low profile ideal for sneak attacks and sniper attacks, similar to ASU-57
• Good reload time (6,5 seconds)

Cons:

• Sluggish acceleration
• Very weak rear speed
• Poor side mobility. Don't expect to be able to turn around quickly
• Weak armour (25/16/16) and susceptible to rear and side shots or even Heavy MG

History

In 1943 the MVTU USSR design bureau proposed an 11 ton tank hunter prototype with two main gun variants:

1/ The 75mm S-1 main gun

2/ The 57 mm S-1-57 main gun

Both would be propelled with a diesel GMC-71 engine.

At the same moment, the GAZ design bureau was working on 2 designs. One named "GAZ-74b" which is the SU-57B with a long barrel, and an improved version with a 76 mm gun.The Su-57a was to be the tank hunter with the 76mm main gun. The Su-57B was not accepted for service because it was too costly to produce and because of its newer diesel engine.

Later the GAZ-74d (SU-76d) would come out with a 76mm S-1 main gun and a frontal armor of 60mm. It will also be known later as "SU-80".
