[Client Values; Actual values in
Specifically, the mismatch in crew values caused by commander's 10% crew skill bonus. Outside of a crew of 1 commander only, 100% crew is a fiction. The client values, given for 100% crew, will normally be taken into battle with 110% crew skill members aside from specific functions, causing their actual performance to deviate from the expected client value. These differences are taken into account in tooltip boxes.

IS-3A


VIII

annoR115_IS-3_auto.png

12190

The IS-3A is a Soviet tier 8 premium heavy tank.

In 1956–1957, the Military Armored Forces Academy developed a speculative design for a new loading system on the IS-3 and T-10 heavy tanks. The IS-3 variant featured a double-row ammo rack with an automatic loading system. The crew was reduced to three members: commander, gunner, and driver. The turret was redesigned in order to accommodate the loading mechanism. The vehicle existed only in blueprints.

Player Opinion

Pros and Cons

Pros:


  • Decent penetration for Russian premium heavy (Slightly worse than the BL-9 on the IS-3)
  • APCR as standard ammunition yields higher velocity at the cost of penetration over distance
  • Improved DPM over the regular IS-3 (2,043 vs 1,835 on the BL-9)
  • Top speed is 2 km/h higher than the regular IS-3, though it is rarely reached unless going downhill


Cons:


  • Terrible power-to-weight ratio severely limits achievable mobility (10.61 hp/t vs 14.26 hp/t on the IS-3)
  • Turret armor less effective than regular IS-3's due to reduction in angle and thickness
  • Extremely poor gun aim time and dispersion values lead to frequent misses
  • Three-man crew limits usefulness as a crew trainer
  • Ammunition is more expensive than the IS-3's (155/400 credits more for standard/premium)


Performance

This tank generally plays like a regular IS-3 with improved DPM, but at the expense of many crippling drawbacks:

The IS-3A has a measly 520 horsepower engine that is even weaker than the stock engine on the IS-3. This severely limits the IS-3A's mobility, especially when trying to climb. Its marginally higher top speed of 40 km/h is difficult to reach, unless going downhill. As a result, it pays to keep the IS-3A on flat terrain, and, if possible, on city streets.

Compared to the regular IS-3, the gun has decent penetration and a superior rate of fire, but is plagued by abysmal soft stats, which make getting those signature IS-3 snapshots extremely unlikely. Having some of the worst accuracy of tier 8 combined with the inconveniently low ammunition capacity of 28 rounds means it is highly recommended to limit most engagements to within 100 meters, where the IS-3A will be able to leverage its higher DPM most effectively.

Unlike the other Tier 8 Russian heavies, the IS-3A gets HEAT ammunition for its premium ammunition, rather than APCR. This requires more careful target selection to avoid hitting sloped or spaced armor, which, when combined with the gun's poor accuracy, can be a problem. It also means that there is a huge difference in shell velocity between standard and premium rounds (1400 vs 820 m/s), which makes hitting moving targets more difficult. However, the standard ammunition performs sufficiently well that it is quite possible to run this tank without loading any premium ammo. In light of the small ammunition load, this can be a very attractive option.

The IS-3A has good armor, with a hull identical to that of the IS-3. The turret, however, is thinner and flatter on the sides and rear, meaning that shots which would have ricocheted off the side of an IS-3's turret are likely to penetrate the IS-3A's. Incidentally, both the gunner and commander are considered "loaders" and it may be worthwhile to train safe-stowage on one of them if a player intends to use the IS-3A competitively.

Overall, the IS-3A is effectively a stock IS-3 with a thicker turret front, improved ammunition, and marginally higher DPM (only 59 DPM more than the 122 D-25T), but with even thinner (and flatter) turret side and rear armor, an even worse engine (worse than the stock IS-3 by 130 horsepower), slower hull traverse, and worse gun handling. All of this combined with the likelihood of seeing tier 10 vehicles regularly makes the IS-3A a tier 8 heavy better suited for more skilled players who can more capably compensate for its many crippling weaknesses.


Early Research

As a premium tank, the IS-3A has no upgrades. Research not required.
