Hello everyone, with the World of Tanks patch 8.10 we will get two new hightier Soviet vehicles – Object 430V2 (rear turret) and Object 430 tier 10 tank. While the tier 9 version is actually quite distinctive, the tier 10 tank somewhat reminds us of the other two vehicles. Let’s check its characteristics then to find the difference between these tanks. As you might have guessed, all three tanks follow pretty much the same pattern: fairly mobile, 100mm gun, decent sloped frontal armor, weak sides, very thick turret. The differences are in details. Size – here, you can see the size difference between Object 140, T-62A and Object 430. Object 430 is kinda small, smallest of the three. Pictures source is a LJ post here. Here, Object 140 is on the left, 430 on the right Here, 140 on the right, 430 on the left And here, size comparison with T-62A (430 is the one without camo) Basics The basic data however are the same: Object 140 and 430 have the same amount of hitpoints (1900) and ALL the module hitpoints (the engine on the Object 430 prototype was quite unreliable and it was expected to be implemented by lowering the engine hitpoints, but that did not happen). T-62A has 50 hitpoints more than 430 (1950). All 3 tanks have the same viewrange (400), 140 and 430 have also identical radios (R-113M, 730 range), while the T-62A has 850 range. All 3 vehicles cost the same (6,1 mil creds) and have the same MM weight (120). Armor For armor estimates, I used the Tank Inspector. The armor of all 3 tanks is different for each. Upper frontal plate for Object 430 is nominally 120mm thick, for Object 140 it is 100mm and for T-62A 102mm. In effective armor terms (calculating in the slope), the upper frontal plate of 430 is 190 to 220mm thick (not a sigle angle slope, the slope gets sharper towards the turret), lower frontal plate (with the same 120mm nominal armor) has around 230 effective armor when shooting from the front. Calculating effective armor is tricky in this case, as most “theoretical examples” simply count the nominal slope and armor thickness, whereas in the game, you will not be shooting at this tank from ideal plane, but from slightly above. Using the same point of view, the frontal plate of Object 140 is cca 175 to 200mm thick (the slope angle changes) and the one of T-62A is notably thinner (cca 160-180mm, depending on the POV). All three tanks have very effective turret armor. 430 has 248mm nominal frontal turret armor, effectively it’s 280 to 300+ armor. Nominally, the thickest armos is near the turret center and on the lower half of the turret, but as the slope progresses, even though the armor zones above the thickest zone are thinner (210mm), their effective thickness is in fact higher due to sharper angle. T-62A has pretty streamlined tough frontal slope armor (from 250mm+ EFF, nominally 240mm), 140 has it more segmented, but effectively the frontal armor of all three tanks is very tough and roughly the same (250-300mm EFF). All three tanks have the hatches on the top of roughly the same thickness (160mm nominal), but T-62A has thicker turret sides (161mm-200mm EFF) with only the rear of the turret being truly vulnerable, while Object 430 side turret armor nominally ranges from 130, over 90 to 50 and 63 at the back and the roof is more exposed (30mm thick), making it theoretically easier to hit. Side armor of the Object 430 is sloped (55mm at cca 60 degress), creating 90mm of EFF armor – the part behind the tracks is thinner however (80mm, no slope), but tracks themselves give you 15mm extra armor. Object 140 side armor is marginally more vulnerable (cca 70mm EFF, 57 nominal sloped) and so is the side armor of T-62A (75mm, no slope). Rears of all three tanks are of course vulnerable. The conclusion is that out of the three, Object 430 is best armored, but not by much and probably not enough to make a difference. Mobility This one is tricky. I tested all three on the 8.10 server to compare them to each other and from what I’ve seen, Object 430 feels slightly, tiny little bit less mobile than the other two (difference between which is small by itself). Object 430 weights (without equipment) 35 tons, 140 weights 35,7 and T-62A 36,7 tons. ALL three have a 580hp engine (the only difference between them is the fact that the 140 engine has a higher chance of catching fire (12 compared to 10 of the other two)). That gives 430 the power to weight ratio of 16,43 hp/t (16,27 with all the equipment), T-62A has 15,68 hp/t without equipment and 140 has 16,11 hp/t. On the other hand, Object 430 has worst terrain resistance of all 3 (0,6/0,7/1,6 – T-62A: 0,5/0,6/1,4 – 140: 0,55/0,65/1,5). Both 430 and 140 have maximum speed of 55 km/h (T-62A has 50). All in all, the tanks are on par, the difference is really small again. Firepower Well, this is going to be easy, as all 3 tanks use the SAME gun: U-8TS. Or, is it? Well, there is a difference. For one, there is the ROF: Object 430 ROF is the worst of the three (8,7 – the other have 9,09), giving it theoretical DPM of 2784, compared to 2909 of the other two. Aimtime is also worse for Object 430 (2,3 compared to 2,1 and 2 of the other two). It’s not that big of a difference, but it is there. The turret rotates the same way as the one of 140 (40 deg/s, T-62A has 48), the depression is practically identical to T-62A (430 has -5/+16,2 140 has -6/+17 and T-62A has -5/+17), just slightly worse. Firepower-wise, 430 comes off as the worst one. Additionally, it has worse accuracy on the move and when turning the turret. Conclusion Object 430 trades a bit more frontal slope armor for a bit less firepower and possibly mobility (it’s still unclear how to measure this exactly). It’s definitely not an OP tank the way it is. It’s possible that the vehicle will be changed, I think it might deserve a bit more boost in the DPM department, but that’s just me. Overall, I believe it will be just fine as a tier 10 tank, just don’t expect miracles: there was a lot of hype about it based on the wikipedia articles (a lot of folks expected it to be OP from what I’ve seen). Those who expected something radically different from the other two tier 10 Continue reading →
