ISU-130

Last updated on 26 April, 2026.

ISU-130 is a tier 8 Soviet TD. It sports extremely high DPM combined with high alpha damage and a quick reload, making it one of the most unique TDs in Blitz. It has weak armour with average mobility.

Armour

(The ISU-130 in the image is using Improved Assembly)

Drag slider right -> to view 185mm AP
Drag slider <- left to view 245mm APCR

Armour when flat and facing head-on:
Upper plate 103mm
Lower plate 110mm
Gun mantlet 160mm

Armour performance:

Strong areas:
-There are no real strong areas of the armour, but the gun mantlet and cabin cheeks are the only areas likely to get bounced shots.

Main weakpoints:
-Both the cabin front & lower plate are weak to all standard ammo, but not penetrable to HE shells.
-The gun mantlet center is penetrable to most enemies.

Gun

Firepower:
-Ammo: AP/AP/HE
-Penetration: 245/215/65mm.
-Alpha damage: 460/530/600
-Reload time: 9.0s
-DPM: 3056 (3521 on premium AP)

Handling:
–Estimated aim time is 3.2/3.5s
–Base aim time is 2.5s, but it can get down to 1.92s.
-Dispersion is 0.308/0.262
–Gun handling is 0.12/0.12/0.1, or 0.1/0.1/0.09 with Vertical Stabilizer.

Usability:
-Shell velocities are 870/870/870 m/s.
-Gun depression is -6 degrees.
-Gun arc is 2 degrees left, 10 degrees right.

ISU-130 has by far one of the best TD guns in tier 8 in terms of its overall stats. Its very accurate, has extremely high DPM on both of its main shells, and great alpha damage. Aim time is unimpressive, but balanced out by incredible gun handling, some of the best in-game.
The only area which it slightly lacks is penetration, as its highest penetration round is 245mm; however in most situations, 245mm of AP is enough to go through most enemies’ armour.

Mobility

Raw stats:
-Forward speed is 43km/h.
-Reverse speed is -12km/h.
-Raw acceleration rate is 15.8 hp/t.
-Engine power is 748hp for its 47 ton weight.

Hard terrain mobility:
-Actual acceleration is 14.4 hp/t.
-Traverse speed is 40.8 deg/s.

Medium terrain mobility:
-Actual acceleration is 12.2 hp/t.
-Traverse speed is 34.5 deg/s.

Terrain resistance stats:
–Terrain resistances are 1.1/1.3/2.1

The mobility of the ISU-130 is quite quite average for a tier 8 TD. Its traverse speed is decent, with an unimpressive acceleration rate. Reverse speed is also quite slow, making it awkward when caught out.

Ammo loadout

The ISU-130 carries a limited 25 shells. With only an 8.8s reload, its not a huge amount of ammo.

Standard AP:
Take 8 of these shells. These are your “premium ammo” as they have increased penetration. You won’t need them very often in battle, but its always good to have enough in case you have to brawl with an E75 (for example).

Premium AP:
Take 14 of these shells. These are your “standard/default ammo” as they deal more damage. This will be the most commonly used shell in battles, so you should take a lot of them.

Note that though this ammo is “premium” its credit cost is cheap, 530 alpha for only 3,600 credits is a very low cost. Other guns with similar alpha premium ammo generally cost 4,400-5,200.

HE:
Take 3 HE shells. HE only deals 70 more damage than your 530 alpha AP shot, so often its not really worth firing. Sometimes these may be needed to clutch a kill against an enemy with 600 HP and light armour, so take a small number of HE.

Ammo usage in battle:
Premium AP should be your default ammunition, its “mechanics” are the same as standard ammo on other tanks: it deals more damage but has less penetration.

If you are not using premium AP as your default ammunition, you may as well not buy the ISU-130. The whole point of this tank is its insane DPM with very high 530 alpha shots and a quick reload.

Equipment Loadout

Gun Rammer:
ISU-130 has sufficient penetration. Even though you may think: “Well its highest penetration ammo is only the same as standard ammo on other TDs”, consider how often you actually need premium ammunition on a tank with 245mm of penetration. Its not often, especially when your tank has great accuracy and can actually snipe weakpoints. Premium ammo is often just an excuse to not aim carefully, especially on tank destroyers.

Gun rammer is what gives the ISU-130 its amazing 3.5k DPM and 9s reload. Not using gun rammer defeats the purpose of this tank, which is to put out enormous amounts of DPM with huge 530 alpha shots and a quick reload.

Camouflage Net:
ISU-130 is a tank that should start off the battle by sniping, so it should use the camo net. It also terrible view range, even with improved optics, so don’t use that equipment.
With a camo net and a level 7 camouflage crew skill, the ISU-130 has 67% camouflage when stationary, 49% camouflage when moving, and 10% when it shoots.

For quite a large and boxy tank, its camouflage is quite impressive. Though it loses almost all of it when shooting due to the large caliber of the gun

Improved Assembly:
Since the ISU-130 has effectively no armour, there isn’t any use to enhancing it.

Instead use improved assembly, it improves the HP of the ISU from an already impressive 1250 up to 1325, which is one of the highest HP pools for a tier 8 TD (one that isn’t a heavily armoured assault TD).

Refined Gun:
The ISU-130 does have a sniping playstyle, so it does benefit from having a smaller aim circle. It also already has the best gun handling of any TD in tier 8, so it does not need vertical stabilizer.
Using refined gun gives the ISU-130 a dispersion of 0.262, which is very good for its alpha damage.

Gameplay advice

ISU-130 plays the role of a typical sniper TD, its weak armour and average mobility mean its too fragile to be anywhere close to the frontlines for the majority of the game. Only later in the battle should the tank be used a bit more actively.

General gameplay:
The ISU-130 starts the battle by sniping, use the good mobility of the tank to find a good sniping position behind a bush and at long distance from the enemy.

Relocate during the battle if your position can no longer get shots on the enemy, don’t just stay in the same spot if you can’t get damage. Your only purpose as a TD is to help the team by dealing damage.

Later in the battle, you can start taking up 2nd line positions, support allied HT or MT, flank enemies, etc. Use the HP of your tank and its good mobility to progress the battle with your allies. Don’t stay sniping for the whole battle, often more active play is needed to win or get good damage.

When you do you push the tank to the 2nd line or frontline, let your allies take hits. Even though the ISU-130 has a decent amount of HP for a TD, it won’t last long if its taking hits for the team. The ISU should only use its HP to trade in a 1v1 situation where it can out-DPM and/or out-trade an enemy.

(Don’t take 2nd line or frontline positions at the start of the battle, always start by sniping from a long distance. Only when there are few tanks remaining should the ISU-130 take a more aggressive role in the battle.)

Be wary of your tank’s mobility limitations:
The ISU-130 reverses slowly, and has very limited gun traverse to the left (only 2 degrees).

This can mean that you get circled by an enemy, or they catch your side. The slow reverse speed and poor traverse arc to the left can cause it to be hard to shake the enemy off.

If an enemy does circle you, try to drive forward then traverse around. The acceleration and traverse speed of this tank are both good, making it easy to move forward and away from the enemy, then get turned around to shoot them (just make sure you have cover behind you so they can’t circle you again).

Similarly, when you play this tank actively, it can be easy to get carried away with the mobility. Going forwards, its a pretty mobile tank, but its very slow in reverse. Be careful not to over-turn your tank when going around a corner, because you won’t be able to reverse quickly, and enemies may be able to take advantage of this and hug your side.

Ammo use:
Always use premium AP.

Don’t load standard AP as your default shell, its the complete reverse logic of playing other tanks, as loading standard ammo by default in the ISU-130 is like loading premium ammo in other tanks.
It deals less damage, but has more penetration.

You should always use premium AP as your default shell. It deals the most damage and is by far the most effective shell in battle, as its penetration is still perfectly fine for a tier 8 tank.
With its sniping gameplay and good accuracy, you often won’t need very high penetration, as most tanks won’t face their armour in your direction (due to being unspotted in a bush).

If you can’t penetrate an enemy with your premium AP, then load standard AP.

Overall

Overall the ISU-130 is a very good tank. Its better than the ISU-152 due to its ability to output damage so much more effectively, along with much improved mobility and hitpoints.

The ISU-130 is a very accurate vehicle with an extremely effective gun, with both high alpha and DPM. Its camouflage rating and mobility are both good, though it lacks armour.

Is it worth getting?

ISU-130 is worth getting if you like high alpha sniping TDs. It has the role of a sniper TD, but is capable of playing a more active role later in the battle.

Players who will really appreciate this tank are players who enjoy accurate and reliable guns, and are able to play both a sniper playstyle and active playstyle during the same battle.

ISU-130 is worth 8,000 gold, its a good tank and has a very unique playstyle, with very few other tanks in the game having similar traits of both high alpha & high DPM.
