  1. 1. Should the T-34 Model 1941/42 be implemented?

    • Yes, in the tech tree
    • Yes, as a premium (please explain)
    • Yes, as a rare/gift (please explain)
    • No (please explain)

Throughout the production history of the T-34, several minor and a few major changes were made along the production lines, the most significant of which we designate as different year-models (i.e. Model 1942). However, this is a rather sloppy system, as it leaves a transitional T-34 Model 1941/1942, bearing features characteristic of both the Model 1941 and 1942, as its name suggests. In fact, there are several types of "Model 1941/42" tanks, each signifying a different stage in the T-34's evolution. 


Many Western sources call this model of tank the Model 1942, while the current Model 1942 with the hexagonal turret is called Model 1943.



An earlier production Model 1941/42 produced at Factory No. 112.




The specific Model 1941/42 I'm presenting is an earlier production model from the end of 1941 to summer of 1942. Other versions of the Model 1941/42 were produced, sometimes up into 1943, but they are not what I am suggesting. This particular vehicle has the solid "dish"-type road wheels, the new 12-spoke idler wheel, the new tow hooks, and the new driver's hatch. The turret is the cast Model 1941 turret, and the bow machine gun and rear transmission access hatch are of the older type as well. 


These models were primarily produced at Factory No. 112 and Stalingrad Tractor Factory. In fact, this tank is very similar to the T-34E (STZ) but without the extra armor. Considering this, the T-34 (1941/42) would fit very nicely at BR 3.7, between the T-34 (1941) and T-34 (1942) in some way.





The extra handlebars and cast turret are clearly visible on this T-34. 


The same T-34 (or T-34s, rather) from a different angle. These also have the square stowage bins installed on the rear.


A close-up of one of Factory No. 112's turrets. This is a later production vehicle, as it contains the newer hull machine gun. The extra handrails and interlocking armor is clearly visible.


One final picture of the No. 112 tank. Most of the defining characteristics of the No. 112 tank are here, such as the road wheels, handrails, and the interlocking armor.




This Model 1941/42 clearly has the new driver's hatch and tow hooks, as well as the characteristic handrails of No. 112. However, the old hull machine gun, as well as an older type of track, are clearly visible. The interlocked armor is less visible, but it is there.


A captured Model 1941/42. It is hard to see, but the driver's hatch is definitely the new, uparmored type. Otherwise, this tank has seen some small modifications, such as the German headlight on the left front of the hull, but the original handrails are clear. The interlocked armor plates can be seen here as well.


The handrails on the rear of the hull are clearly visible here.


More pictures of the side of the tank. The handrails on the engine deck are visible.




In June 1940, Factory No. 183 in Kharkov began the construction of the T-34 tanks. Initially, these were all built with the welded turret, mounted the L-11 gun, and had the SPKO periscope in the turret roof hatch. In January 1941, the transition from the L-11 to the F-34 began, as well as production at the STZ factory. Around this time, the cast turrets also began production simultaneously with the welded turrets.


From January to June 1941, KhPZ and STZ produced tanks nearly identical to each other, with a few minor differences in tooling. The major differences between these Model 1941 tanks and the old Model 1940 tanks was the removal of the SPKO periscope from the roof (this actually was removed before Model 1941 production began), and the defining feature, the F-34 gun. 


In September 1941, welded turrets received a new rear plate, secured by 8 bolts to allow easier access to the gun for maintenance. KhPZ began its evacuation to Nizhny Tagil to create UTZ. Factory No. 112 in Gorky also began production, using kits from KhPZ. These were all constructed with cast turrets. These tanks were also constructed with the new driver's hatch and tow hooks, creating the first Model 1941/42 tanks. However, these tanks used the M-17 petrol engine due to a shortage of the V-2 diesel. An all but 5 of the 161 tanks produced at No. 112 in 1941 were produced to this standard, the other 5 containing the V-2 diesel. KhPZ and UTZ also produced tanks to this standard. STZ would wait until November 1941 for these changes to take effect, but with their own unique signatures: a sharp-edged welded turret and a full set of steel wheels with internal shock absorbers.


In late 1941, probably in November, No. 112 also introduced the new round transmission hatch with 4 access bolts, along with the interlocking armor plates. By January 1941, the V-2 diesel was available in sufficient numbers to become production standard. In May or June 1942, the new hull machine gun was introduced. Factory No. 112 had one other major characteristic of their design: handrails everywhere. On a standard T-34 from KhPZ, UTZ, or STZ, there were only 4 handrails on the hull sides, sometimes two on the engine deck, and one on each side of the turret. Factory No. 112 put two on each side of the turret, and also two on the front and rear hull, and four on the engine deck. The transmission access hatch usually also had one.


The model of T-34 Model 1941/42 produced from January-April 1942, with the V-2-34 diesel but the old hull machine gun, is the variant that I am suggesting.


STZ would also continue the same production standard until it was overrun during the Battle of Stalingrad in October 1942. The interlocking armor plates created by No. 112 were also used here. It is probable that STZ tanks never received the new hull machine gun design. 


UTZ would continue producing the Model 1941/42 tanks until April, when the new hexagonal turrets were introduced into production. Later on, the design would evolve further, with more tweaks and changes. 


After the end of 1942, the differentiation between models and when they were produced becomes spotty at best. The only other production feature worth noting is the uparmored tanks, which were produced in small numbers in February 1942 in all 3 major factories. These were 15 mm plates welded to the front hull and sometimes to the turret. The production of these tank was also inconsistent, with at least one example of the hexagonal turret being fitted to the uparmored hull despite being produced nearly 2 months later.

 ("Tanks" refers to Model 1941/42 tanks of early 1942 production)


1 - Tanks at No. 112 Factory were produced exclusively with the cast turret

2 - The armor plates on these tanks are interlocked, just as on the T-34E STZ in-game

3 - The road wheels are all the solid type, as on the T-34 1941 in-game.

4 - The handrails were applied as in the photographs. Two on the front hull, four on each hull side, four on the engine deck, two on the hull rear, and one on the transmission access hatch.

5 - These tanks had the original hull machine gun mount.

6 - These tanks had their front hull completely welded; there should not be any bolts as found on the T-34 1941.

7 - This tank is overall similar to the T-34E, just without the armor. In fact, the T-34E was also produced by Factory No. 112, but in early 1943.

8 - The transmission access hatch had only 4 bolts, not the traditional 7.
