Armour

(The Obj.452k in the images is using Improved Assembly)

Drag slider Right –> to view 258mm AP
Drag slider <– Left to view 340mm HEAT
When flat and facing head-on:
Upper plate 305mm
Hull shoulders 350mm
Lower plate 120mm
Lower-lower plate 82mm

Turret face 440-650mm
Cupola 35-45mm

---

Note that even though the upper plate is a high effective thickness (305mm), its base thickness is low, being only 105mm thick.
Normalization causes this upper plate to be quite weak, especially if a tank is looking down on your upper plate, or in close distance.

The image below shows 2 different distances, both are in fairly close range.

The image above shows the same 120mm gun with 258mm penetration, but on the left its at 56m distance, and on the right its at 22m distance. The upper plate is weaker at close distance, due to the gun of the enemy tank being higher up compared to the fairly low slung hull of the Obj.452k.

Side armour:
The Obj. 452k has 60mm base side armour, with 5mm spaced armour covering the tracks and sides.

This armour is not effective for angling, as the base 60mm is thin, and the tank also has “shoulders” which become weak when the hull is turned even slightly.

The 5mm spaced armour is very thin, and causes enemy shells to gain a high amount of shell normalization, as the low thickness causes the double overmatch mechanic to occur.

The image below displays this perfectly:

Armour vs all tier 8-10 tanks:
The armour of this tank performs roughly the same against any enemy you face.

Upper plate:
This area is somewhat strong, but not always reliable.

Its angle is around 68-69 degrees, meaning its just slightly off being an auto-ricochet. If its angled upwards slightly, then it will bounce all AP and APCR rounds.

However, due to this upper plate relying so heavily on this angle, its quite thin, at only 105mm nominal thickness. This means that normalization has quite a big effect on it, bringing down its effective armour from the listed 310mm, down to around 253mm.
(This is because AP gets 5 degrees of normalization, which basically removes 5 degrees of angling from any angled armour plate.)

Due to this, even the slightest angle downward, or an enemy being slightly taller than your tank, will cause the upper plate to be penetrable quite easily, hence why its not always reliable (its also why the upper plate is so much weaker in close ranges).

Lower plates:
This area is enormous, and very weak. Angling the hull doesn’t benefit it, and the lower plate can always be penetrated.

The lower-lower plate (this is the more angled part that’s below the lower plate), is also just too weak to bounce anything.

Both of these armour plates are very weak and easy for even “cheap HESH” to penetrate.

Turret:
The turret is impenetrable. This is shown below.

Its very thick, but its also angled back at 70 degrees, meaning that AP and APCR are useless against this turret, as they will always bounce due to auto-ricochet.

The only weakpoint on this turret is the cupola, which is very weak but also very small. It disappears when the tank uses gun depression.

Angling/sidescraping:
The Obj. 452K cannot angle or sidescrape at all. As stated above, its side armour is thin, and it has “shoulders” which are easy to penetrate when the hull is turned.

Overall armour effectiveness:

The armour of the Obj.452K is overall terrible.
-Sure, its turret is “OP”, nothing can penetrate it when the hatch is hidden. However the turret is only used in a relatively small portion of gameplay (compared to an entire battle).

-The hull is atrocious. Its very large, as in its both very wide and quite tall (compared to the short and compact turret). The lower plate is huge, and comes up very high on the tank, making it hard to hide and use gun depression without accidentally exposing the lower plate (this happens very often, most gun depression positions aren’t sufficient in hiding this very high-up lower plate).

-The wide hull causes gun depression use to be awkward, as the tracks will wedge the gun upwards in narrow or uneven hulldown positions (this causes it to have less gun depression in some positions, you can see how this is important here).

-Due to the small upper plate, the flat hull sides come far forward on the tank. It makes the hull side profile basically just a large and flat rectangle, and this means it will catch shots under the turret when you poke a corner.
This wouldn’t happen on other tanks, the E 75 for example, the hull front is far more angled, causing its hull profile to be more sleek, and it gives enemies less to shoot at when the hull side is exposed.

Essentially, the turret is impenetrable, but the hull is useless, it cant sidescrape, it can’t angle, its lower plate is enormous, and its upper plate is only sometimes effective. On top of this the tank’s hull is wide, long, and has a very tall lower plate, making it easy to catch shots when hulldown.

Playing against an Obj.452K

In a facehug:
In the images above the tank shooting the Obj.452K is an AE Phase I, a tank which is taller with a higher mounted gun than the Obj. 452K. This is common, as the 452K is so low profile.

There are a few options when facehugging this tank, and the view looks different depending on whether you point the gun up or down to aim for weakpoints.

Sidescraping:
If you see an Obj. 452K sidescrape, shoot its hull shoulders, its front track wheel, or any flat and grey area, preferably close to the front of the tank.

Its sides are very weak and don’t hold up when angled or in a sicdescrape position. Even the lowest caliber shells can easily penetrate the Obj.452K’s hull sides, at almost any angle.

HE areas:
The turret side can be penetrated by HESH with over 165mm penetration. The lower plate is penetrable to 120mm-125mm HESH penetration.

The engine deck area on the side of the tank has no spaced protection, this is only 60mm thick.

The hull rear is 50mm thick, the turret rear is 65mm thick.

When using gun depression:
When this tank hides its hull, there’s basically nothing you can do to counter it.

You can try to aim for that very small weak bar under the gun, or for the small viewport on the hull, which are both penetrable but very small.

The only other option is to try shoot HE towards the bottom of the turret so it splashes down onto the hull deck.

Gun

The Obj.452K mounts a 130mm gun

-Alpha damage is 460 on AP, 390 on HEAT, and 600 on HE
-It has a 11.6s reload, giving it 2375 DPM
-Penetration on AP is 246mm, HEAT is 320mm, and HE is 65mm.
–Estimated aim time is 4.2/4.6s
–Base aim time is 2.6s, but it can get down to 2.12s.
-Dispersion is 0.344/0.310
–Gun handling is 0.19/0.22/0.13, or 0.16/0.19/0.11 with Vertical Stabilizer.
-Gun depression is -7 degrees

Overall this gun is decent. Its penetration, aim time, and DPM are all decent, but nothing special. Gun handling is average with decent aim time & dispersion for a tier 9 heavy with 460 alpha. What’s special on this gun is its good DPM, higher than any other tier 9 heavy with such high alpha.

The gun depression of -7 degrees is decent since the tank is quite low profile.
The wide hull of the Obj.452K can make it awkward for using gun depression on uneven terrain, since the tracks just catch on the terrain and prop the gun up. The gun is also mounted on the highest point of the tank (this is good for poking ridges since it hides more of your armour, but not so good for aiming down).

Mobility

-Top speed is 40km/h forwards, and -12km/h in reverse
-Traverse speed is 34.6 deg/s on hard terrain, and 27.6 deg/s on medium terrain.
-In game acceleration rate is shown as 16.5 hp/t, it has a strong 913 horsepower engine for its 55 ton weight.
-Actual acceleration rate is 16.5 hp/t on hard terrain, and 12.7 hp/t on medium terrain.
–Terrain resistances are 1/1.3/1.8

This is great mobility overall. The top speed is good, acceleration is very impressive on both terrain types, and its traverse is decent. The only real downsides here are the slow reverse speed, and slow traverse on medium terrain. Overall this tank feels quick, its not hard to relocate in battle.

Equipment, provisions, & consumables

The Obj.452K does not have any special provisions or consumables.

Gun Rammer/Calibrated Shells:
The Obj. 452K doesn’t lack penetration. Its penetration isn’t impressive, but its also not bad; it also doesn’t lack DPM, so either equipment piece can work well on the tank.

Use gun rammer if you want to have a slight DPM advantage over other tanks with similar alpha damage.

Use calibrated shells after you’ve tried the tank in battle with gun rammer. If you feel that the tank really needs more penetration, or want the higher penetration to compensate for accuracy, then use calibrated shells.

Improved Modules:
As with any tank, every player will have a different experience with module damage, as often this depends on both how you play the tank, where you take it on the map, how you use the armour, and of course RNG.

However, due to the Obj. 452K having very weak hull armour, both on the front and sides, it is often penetrated by enemy shells. Its ammoracks just so happen to be where most enemies shoot the tank, at the front left and front right sides of the hull.
These ammo racks have very low HP, as even small caliber guns are capable of damaging them.

Improved modules will improve the ammorack durability.
(If you keep playing the tank and still find the ammoracks getting damaged often, consider using protective kit)

Improved Assembly:
The 452K’s armour relies on auto-ricochet angling, so enhanced armour doesn’t really benefit it.

The lower plate is enormous, and too weak to enhance. The upper plate would remain weak, even if it was enhanced; and the turret does not need enhancing, as its almost 700mm thick on flat ground.

Use improved assembly, it will increase the Obj.452K’s good 2100 HP up to 2226 HP.

Improved Control:
The Obj. 452K has a very strong engine for its weight, so its able to very quickly accelerate to its top speed. However its traverse speed, especially on medium terrain, isn’t good.

Good traverse speed is just as important as acceleration on a heavy tank. Traverse lets you turn the armour to face the enemy quicker (though that’s less relevant on this tank), and it lets the tank reposition and maintain its speed better. The 452K has excess acceleration, so it can afford to lose some to be able to gain traverse speed.

Using improved control will give the Obj.452K 35.75 deg/s traverse speed on hard terrain, and 28.5 deg/s on medium terrain.
Its acceleration will still be very good, with 15.5 hp/t on hard terrain, and 11.9 hp/t on medium terrain.

Vertical Stabilizer:
The Obj.452K has quite mediocre gun handling for a tier 9 heavy tank, with 0.22 dispersion on hull traverse being among the worst in tier 9.

The 452K often won’t have time to fully aim in each shot, and therefore refined gun generally won’t benefit the tank. Its better to use vertical stabilizer, as it will help the reticle to aim in faster after moving, which really helps the tank in its fairly active playstyle, and as the tank itself can get up to quite a good speed.

(Try refined gun if you really feel that the gun just doesn’t work with vertical stabilizer. Since the Obj.452K has such an impervious hulldown armour profile, it can sometimes afford to sit still and fully aim in. In situations such as this, the better accuracy of refined gun does benefit the tank.)

Gameplay advice

The Obj.452K has a very odd playstyle, its almost like other tier 9 heavy tanks, such as the WZ-111 1-4 or the IS-8, but not quite.

The 452K lacks armour more than any other tier 9 heavy, so it can’t be nearly as confident in its armour use. On the other hand, it has impressive DPM for a gun that deals 460 alpha, and its able to get into positions pretty quickly. This tank works well as a heavium tank (or just a large medium tank) only. Any situation were you would expect to have armour doesn’t work for this tank, and it will generally perform badly.

General gameplay:
The Obj. 452K is a heavium/large medium. Its hull armour doesn’t work in ANY situation, so you can’t put the tank into any situation where you would need hull armour to do well. You have to position and play this tank based around 2 things, these are its mobility and its high alpha/good DPM combination. Hulldown gameplay should be secondary and not a priority, this is explained more below.

Its hull armour won’t work no matter which enemies you face, so which side you take it to depends on the team lineup, which is different each battle.

Use the good mobility to reposition in the battle, don’t over-extend into early positions where you’re vulnerable to be rushed. The Obj.452k is bad at retreating (due to slow traverse and reverse speed), and doesn’t have the armour to hold up when being pushed, so just try not to get into situations where that may happen. For example, pushing bases without much support can be risky.

Push with allies to break through enemy flanks. The 452K does this well due to its good speed and nice DPM for its alpha.

Focus on your strongest points when playing this tank, these are its speed, and its DPM/alpha combination. Turret armour is a strong point, but doing hulldown wastes both the speed and the DPM of this tank, hence why playing a hulldown role should not be a priority in the 452K.

Don’t prioritize being hulldown:
If you prioritize hulldown positions, then you start playing the tank more like a real heavy. You fight heavies in hulldown positions, you have to trade damage like a heavy, and you’re prone to being pushed by heavies.

Do use hulldown positions in battle, but don’t prioritize them. If you put hulldown as your tank’s priority, it puts you into the same position as armoured and proper heavy tanks, which you just can’t play the role of well. This tank needs to prioritize its strongest points, which are speed, alpha, and DPM.

Hulldown positions do work for this tank, but only because of its turret, not its gun, not its hull armour. In a hulldown situation, generally your good DPM/alpha combination can’t be put to good use, since hulldown gameplay is usually just damage trading, and you can hide for as long as you need to reload.

(In the gameplay video below, you can notice that the tank is never rushed into a hulldown position at the start of the battle, despite there being hulldown positions to use. While these are specially chosen games, out of all battles played in the Obj.452K, the ones where the tank performed best were battles where the tank wasn’t played as a hulldown heavy, but instead taking the role of a big MT).

Positioning:
Where you take this tank could be different on each map. Since this tank’s performance is so different based on what map its on, who your allied heavy tanks are, and who the enemy heavy tanks are.

With positioning, prioritise hard cover, this is anything that you can hide the tank behind, such as buildings, terrain, rocks, etc. This is good for peeking enemies, shooting, then immediately into cover. Since the tank has no hull armour, hard cover is the only way to avoid damage when your hull has to be exposed.

Hulldown gun depression positions are the only positions where the tank’s armour works. Obj.452K’s turret is impervious, so will be able to bounce shots as long as the hull is hidden.
Note that hulldown positions should be secondary. Playing a hulldown role wastes both the mobility and the DPM that the tank has, 2 of the actual good traits on this tank.

Avoid trying to play this tank like an armoured vehicle, since it just won’t work. You have to position it similarly to an IS-8 or WZ-111 1-4, similar tier 9 heavies with poor hull armour but strong turrets. The -7 gun depression makes it less awkward to position than those other 2 tanks, but you still have be wary of the limitations due to the wide hull and fairly high mounted gun.

Play the tank as a heavium:
This tank has no armour. You cannot play it like the tank will bounce shots, because the tank doesn’t.
If playing the tank as a true heavy, Obj.452K has to be cautious due to its armour. This cautious nature causes its mobility and its gun to be wasted.

You have to use peek-a-boom tactics in this tank, and play it like its a strong-turreted medium tank. It won’t bounce anything if your hull is showing, and you can’t angle or sidescrape.

Due to not having armour, you may find it hard to deal damage as a heavy tank. It can’t make the plays other heavies make, plays that reward you with getting damage. It can’t push, it can’t trade damage (with bounces), it can’t sidescrape, and it can’t angle. it can’t be confident with its armour nor its gun.

Avoid facehugging enemies:
Due to having a very weak hull, and a few weakpoints on the top of the tank, the Obj. 452K cannot facehug well.

If enemies have a low enough profile, or good enough gun depression, the hull is very easy to penetrate.
If enemies can’t hit the hull, they’ll still be able to hit the cupola or the area right above the gun.

Avoid sidescraping and angling:
As discussed above, this tank has terrible side armour. Its even weaker than most medium tanks, and it means this tank cannot employ angling or sidescraping tactics in its gameplay.

If you try to sidescrape or angle in this tank, all enemies will just easily go right through the side armour or the track wheel.

Show your hull sides to HESH:
In most tanks this is completely counter-intuitive, however due to the Obj.452K having such a huge and weak lower plate, showing the side of the tank actually makes it much harder to penetrate using HE ammo types, such as HESH or premium HE (this is due to the sides being covered with spaced armour).

Turning the hull to the side against FV 183s, for example, could save you a lot of HP from taking a HESH shell.

---

The Obj.452K has very unusual and awkward gameplay due to its weak armour. It needs to prioritize using its mobility and good combination of DPM with 460 alpha damage. Hulldown positioning can be used if that’s the only option, but this shouldn’t be prioritized since it wastes the gun’s DPM and the tank’s good speed. It also forces the 452K to play as a “proper heavy”, which it just doesn’t do well.

The tank works best as a large medium tank, or a heavium.

Tank gameplay:

The 6 battles in this video are the best games out of a 20 battle session (not including the first game for 2.7k dmg).

In these 6 battles, notice that the tank isn’t initially put into positions to use its armour. The only times the armour gets used are after the tank has already flanked enemies and is in a position where it can be hulldown.

Also notice how buildings on flat ground are the preferred choice of cover, since the tank can use its alpha to trade & use the building to hide on reload, but still has the choice to change position or retreat easily.

---

Author note:
In these battles I checked the team lineups to choose where to go on the map. With heavily armoured/high hp/high alpha/hulldown/higher tier enemies, generally I’d avoid being frontline or hulldown on the heavy flank, and rather take 2nd line positions or just wait for spotting info then flank. Flanking to use the gun generally brought the best battle results, since that gameplay style emphasized the tank’s strongest points most.

I also chose the gun’s great 460 alpha combined with almost 2.4k DPM, with good speed, to be the main priorities in battle. I only defaulted to turret armour on maps where that’s the only option, such as on Mines if you’re one of the only heavy tanks. Even on the Dead Rail battle shown in the video, rather than staying in the hulldown ridge position, I used the mobility to flank.

Before doing what I mentioned above, I was focussing on using the hulldown abilities, strong turret, -7 gun depression, & good DPM/alpha on the tank. The tank performed terribly and didn’t work at all. It may just be down to player gameplay preference, but once I focussed on the mobility and DPM instead of the hulldown ability, all my stats in this tank significantly increased.
(I also switched to refined gun, hence the seemingly terrible aim time/gun handling but good accuracy in the video)

Overall

Armour – 3/10
Gun – 5/10
Mobility – 6/10
Speed – 6.5/10

Armour is overall weak. Upper plate is very small and only sometimes works. Lower plates are both huge, very weak, & hard to hide. Sides are extremely weak, armour is useless for angling or sidescraping. HE protection is good, HESH protection is mediocre.
Gun is decent. The DPM & alpha combination are great, reload time, penetration, aim time, & accuracy are decent. Gun handling is mediocre. -7 gun depression is decent.
Mobility is good, with a very strong engine and effective acceleration rate, however slow traverse speed and slow reverse speed of 12km/h.
Speed is good, 40km/h.

Overall the Obj. 452K is not a great tank. While its stats are decent, the fact it cannot use its armour in any situation other than hulldown just makes it very awkward to play as a heavy. While it works pretty well as a heavium, there are just better tier 9 heavium choices to take.

Is it worth getting?

The Obj. 452K is not worth getting. It offers absolutely nothing new to tier 9 heavies that are already in the game, in fact its a lot worse than all other tier 9 heavies due to its terrible hull armour.

Really any tech tree tank will be more comfortable to play than this tank. If you want a tank with similar alpha and good speed with turret armour, try the WZ-111 1-4, 50TP Tyszkiewicza, TNH Vz.51, or even the IS-8. All can do what the 452K does, just better or in a more comfortable manner.

If you want to get a tier 9 collector/premium heavy with great turret armour and gun depression, along with high alpha, you could just get an Obj. 752 or WZ-114 instead. Both of those tanks are both much stronger in terms of performance and competitiveness, but they are also both much more enjoyable to play due to better or more comfortable statistics & gameplay.

The Obj. 452K is worth 8,000 gold. Its an ok tank, and it definitely can perform well in battle occasionally (like all tanks can), its but its not a great tank tank. While it does offer a few traits which are a bit interesting, such as the alpha, DPM, and speed; there are just as many traits which make it frustrating to play, such as the gun handling and complete lack of hull armour.

This tank has such a low value as it offers no unique gameplay, no enjoyable aspects, its gameplay is challenging and often frustrating,  and its arguably just worse than most other tier 9 tanks.

Historical info:

The Obj. 452K is a fake tank made by WG.

It seems to use elements mainly from the Object 780 in its design. This is most noticeable with the overall design of the hull, having a fairly similar design to the Obj. 780’s hull, just with some changes to angling and how plates are shaped, etc.

The gun is the M-65K, the same gun used on the Object. 279. This gun has a very unique muzzle break, which may just be designed by WG to make the tank look cool.
