Somewhere in fantasy land!

I’m gonna do another pass of corrections again.

1. This is not a ZiS-22. Ignore my previous belief that this was an earlier ZiS-22



This gun with the flat mantlet and longer barrel is the ZiS-22, which was an F-22 barrel imposed onto an F-34 breech.


This KV-1 is carrying an “unmodified” F-34, which was done in February 1941. And here is also the order for it, as it was to be done before March 1st 1941.

2. The T-221 (“KV-3”) was partially built.

Just not as originally planned. After the realisation that the F-30 wouldn’t fit, the T-221 eventually morphed into the same elongated hull as the T-220 but with the 90mm armour layout of the T-150. The hull was partially built, and was later to be reused to create the object 223 prototype in order to save production time. But even this didn’t happen.

3. KV-13 (Объект 233) (1942) was not called object, just 233. And it carried a ZiS-5 cannon.

5. IS-1 Prototype (Объект 233IS) (1943) (Improved KV-13) did not use a ZiS-5 cannon, but an F-34.

Why it didn’t use a ZiS-5 I haven’t seen any explanation for.

5. The KV-13 (Объект 234) and IS-2 Prototype (Объект 234IS) are the same tank.


The proposal to mount a 122mm in the KV-13 came in late 1942, when work on the improved KV-13 (IS-1) had already begun. Though the prototype carried the KV-9 turret with U-11 howitzer, the plan was to mount an improved howitzer D-12 in the lower profile improved KV-13 turret. This never got completed by the time the prototype was built though.

This is also not a prototype for the later production IS-2. Their connection is none. They just happen to share a name and gun bore diameter.

6. Just so we’re clear, the name “KV-85G” is an unofficial one.

7. There is another KV-85 variant that could be added to the list, the “Improved KV-85”

It was a proposed counter project against the IS-1, where ChKZ SKB-2 proposed that the KV-85 could be kept in production instead of replacing it with the IS-1 by completely reworking its armour and giving it sloped front plates. No drawings have survived though.

“The front of the hull is the most interesting part. According to the description, the thickness of the armour increased to 90 mm, and the shape of the plates changed. The top plate was angled at 30 degrees, and the bottom at 60 degrees to horizontal.”

8. Note that the KV-220 never went into battle with the 85mm turret.

Both KV-220 prototypes saw service with regular KV-1 (F-32) turrets.

9.The IS-1 (object 237) prototypes were armed with S-31 and D-5T guns. The S-18 was the SPG version of the S-31.

And seperating them into “IS-85 (Объект 237)”, “IS-1 (Объект 237 Nº1)” and “IS-1 (Объект 237 Nº)” is weird. Object 237 index is simply refering to the project itself. Both prototypes (No.1 and No.2) had 6 road wheels. They hardly differed at all. And they were both initially armed with S-31, and later both rearmed with the superior D-5T.

10. There’s also the actual IS-2 model 1943 that should be added.

Initial production of the IS-2 that ran between December 1943 and March 1944 (145 tanks) were armed with an earlier variant of the D-25T that still had the interrupted screw breech and “Ferdinand type” muzzle brakes inspired by the… Ferdinand.

11. The IS-2U was never built.

The improved IS-2 design named IS-2U designed by Experimental Plant No.100 was only submitted in November 1944 and came to late to be approved. As the IS-3 prototype (Kirovets-1) was already present and impressing all higher ups.

ChKZ’s improved IS-2 design however, was built. In September 1944. But it didn’t have as catchy of a name as Experimental Plant No.100’s contender.

It too had a narrow turret. But its hull front was essentially identical to the production 1944 model. But there were many changes to the engine compartment. This, though unconfirmed, certainly served as the inspiration for the IS-3 prototype (Kirovets-1), as the team gave up on this vehicle, and started designing the Kirovets-1 at around the same time.

12. Got a source that object 252 was ever called IS-5?

I have seen some suggestions that Experimental Plant No.100 used the IS-5 name during development of their improved IS-2 designs, which led to the object 252. But I’ve never seen anything concrete. It also doesn’t make sense, as they were the ones that designed the object 248 IS-5, hence why they named their next creation IS-6 (object 252). But there’s still the possibility that they considered these new designs evolutions of their IS-5 tank already, and thus kept the name. But without a decent source I wouldn’t spout it.

13. IS-5 (object 730) was not a further development of the IS-3.

Although the design took inspiration from both the IS-3 and IS-4. It was still a completely new development. It also took heavy inspiration from the developments of the IS-7. It was the culmination of all knowledge they had at that point.

14. Unlike commonly said, Khrushchev didn’t cancel all heavy tanks in 1960.

He expressed a will to do so, but it wasn’t an order. It did effectively kill all heavy tank programs, but the object 279 project still lived on until January 1961, and the object 770 until February 1961.

A.G. Solyankin , I.G. Zheltov, K.N. Kudryashov. (2010) Domestic Armored Vehicles XX century Volume 3 1945-1965.

15. Got a source that “object 743” was used for T-10M?

To me that just looks like a spelling error. Someone accidentally swapping the 3 and 4 of object 734.

KV-3 (Obj. 223), KV-8/8S, KV-9, KV-1K, and KV-100 would all be amazing additions to the game.

Thanks as always for the help!

  1. I don’t remember where I got that from xD

  2. I think you’re right. I’ve just removed it from the list since it served no real purpase anyways.

T-42 and t-39 super heavies from the interwar period, both would lead to the development of the t-35

There is also the 1000 ton festungs panzer (fortess tank), not sure if you would count it though.

There are also the first world war landships designs like: the tsar tank

275-ton cruiser tank

There are are a few production T-35s you missed: the original obr. 1934 g. T-35, though its only differentiated from the in-game T-35 but using the 71-TK radio station instead of the later 71-TK-2 starting from 1935, and then the 71-TK-3 starting from 1936. Additionally, the obr. 1938/39 g. can be again differentiated by their radios: the first equipped with a handrail antenna, the last equipped with a whip antenna, and then the last three tanks also receiving a turret box.

The T-100 can also be differentiated into two versions: initially equipped with the weaker L-10 gun, but rearmed with the stronger L-11 gun by the time of the Winter War.

The KV-1s can also be further differentiated. In total, there were three types of turrets during their production run:

  • Welded turrets with a rectangular rear
  • Welded turrets with a rounded rear (which I personally call “composite” turrets)
  • Cast turrets with a rounded rear, used as early as the initial 1939 models despite popular perception

All three were produced at the same time throughout the KV-1’s production run. Adding even more confusion into the mix, some were also equipped with the M-17T engine instead of the standard V-2K engine starting from late 1940; though all M-17T-equipped tanks would later be converted back to a V-2K engine starting from 1942, assuming that the order was followed fully. Then including the four major models: the obr. 1939 g. with the 76-mm obr. 1938/39 g. (L-11) gun, the obr. 1940 g. with the 76-mm obr. 1939 g. (F-32) gun, the obr. 1940/41 g. or 1941 g. with the reinforced applique armour, and the obr. 1941 g. or 1942 g. with the 76-mm obr. 1939 g. (ZiS-5) gun; and you have easily over a dozen variations of the baseline KV-1.

The KV-85 can be further differentiated into two versions, the one based off of the KV-1 hull (in-game) and the one based off of the KV-1S hull. They both would perform identically, though the latter would have a bolted-up hull machine gun port.

The IS-1 also had the Object 237 prototypes, with the first one using a 85-mm S-31 gun and the second one using a 85-mm obr. 1943 g. (D-5T). Though, I don’t know if the prototypes had anything else that differentiated them from the production model, which would make them identical to the one in-game, since the S-31 has the same performance as the D-5T.

The IS-3 also had the IS-3K and IS-3MK command models, with the latter having the same upgrade as the IS-3M. Though, like the Object 237s, I’m not actually clear on what the differences they have with the normal IS-3s, though I would assume they had extra radios or longer-ranged ones that would require additional space, probably at the sacrifice of ammunition.

The IS-4 can be differentiated between 1947 and 1949 models, with the 1949 models being produced with a better transmission.

The T-10s can also be further differentiated. The T-10B had their own command model, the T-10BK. The T-10Ms and T-10MKs can be differentiated into four models: the original obr. 1957 g., the obr. 1962 g. with a 6-speed gearbox, the obr. 1963 g. with an underwater driving system, and the obr. 1964 g. with an automatic fire extinguishing system. In 1967, which is the in-game version, it was also given HEAT and APDS ammunition, though I’m not certain if that could actually be specified as an additional variant or not if the tank itself didn’t have to be modified to accommodate the new ammunition.

The different variants of Matildas and Churchills they received are as follows:

  • Matilda II Mk. III
  • Matilda II Mk. III CS
  • Matilda II Mk. IV
  • Matilda II Mk. IV CS
  • Churchill Mk. II
  • Churchill Mk. III
  • Churchill Mk. IV

The CS (Close Support) versions would be ill-advised to add into the game since the O.Q.F. 3-in Mk. I is equipped exclusively with only high-explosive and smoke projectiles, capable of 10 mm of penetration. On an unrelated note to that, later CS versions of tanks were equipped with the O.Q.F. 95-mm Mk. I with a high-explosive anti-tank capable of 127 mm of penetration, but Russia received no tanks equipped with that gun.

They also captured and used Tiger I tanks, though the only specific model I’ve been able to track down of them using is a 1942 model. I don’t know what other models of the Tiger I they used, if any. They did capture Tiger IIs, too, but never used them in combat as far as I’m aware like they did with Tiger Is and various other German tanks like the Panthers, Pz. Kpfw. IIIs, IVs, and 38 (t)s.

Edit: The White Army also received Mk. V Composites which were later incorporated into the Workers’ and Peasants’ Red Army. These saw service as late as the 1940s and were considered to be “heavy tanks” due to their weight (28 long tons~), whereas mediums were defined to be in the 15 long tons~ range (set by the 15.7 long tons Medium Mk. A Whippet) and lights were defined to be in the <10 long tones~ range (set by the 7.2 long tons Renault FT).

The in game KV-85 is already based on the KV-1S hull, no tank named KV-85 was ever built on the regular KV-1 hull

I got myself mixed up. The KV-85s were initially produced with KV-1S hulls rather than purpose-built modified hulls, resulting in the hull machine gun port having to be welded and the turret ring to be cut out further. The KV-85 in-game is a later production version that uses a purpose-built hull.

That’s fair but can you tell me where did you find that information? As far as I’ve seen the only example of the tank with a plugged mg hole is the Object 239 prototype (because it started it’s life as the second KV-1S prototype). Production KV-85s having conerted hulls seems to be an internet myth to me


“Let’s put on the move the most powerful tank of its time - IS-7

Today the Soviet heavy tank IS-7 went to the Restoration Laboratory of the Patriot Park.

In terms of total combat performance, at the time of its creation there were no tanks equal to it in the world

IS-7 is the crown of evolution of heavy tanks. You can see the only existing example of the IS-7 in Patriot Central Park!

The history of this unique machine is in an article on the website

Specialists from the Restoration Laboratory will carry out restoration work in the coming days, after which the exhibit will return to the 1st pavilion “Heavy tanks and self-propelled guns of the USSR” of the Tank Museum (Technical Center) of the Patriot Park.

If there are a lot of, we will talk about the progress of the restoration.”

Reviewing the information, you’re correct. Sorry for spreading that internet myth.
