Durchbruchswagen 1

The Durchbruchswagen 1 was the first in a series of heavy tank designs that ended with the Panzer VI Tiger, and was produced after several years of discussion within the German military establishment.

The first concrete steps came late in 1935, when Maybach was asked to produce a specialised tank engine, so that the German army could avoid using modified aircraft engines. The aim was to produce 600-700hp engines, but they wouldn't arrive in time for the DW prototypes, which were powered by the 300hp Maybach HL 120 of 1936.

The second step came in November 1936, when Krupp was asked to produce a design for a turret armed with a 7.5cm gun, suitable for use on a 30 ton tank.

The third step came in January 1937, when the tank design office of the ordnance department (Wa Prw 6), asked Henschel to design the chassis for a 30 ton tank. At this stage the new tank was named the Begleitwagen (verstaerkt) or 'escort tank, (strengthened), suggesting that it was seen as having a similar role as the Panzer IV, the original Begleitwagen.

On 12 March 1937 the name was changed to Infanteriewagen, suggesting an infantry support role.

On 27 April 1937 the name was changed once again, this time to Durchbruchswagen (D.W.), or break-through tank. In 1939, after the adoption of the VK designation system, the D.W. became the VK 30.01 alte Konstrucktion (old design), an acknowledgement that was the precursor of the VK 30.01.

The D.W. 1 had a simple boxy hull and superstructure. The superstructure was the same width as the hull, so didn't overlap the tracks. The front of the superstructure was over the front road wheel. The D.W.I had cast steel road wheels with solid rubber double tires, and a 300mm track pitch. It used torsion bar suspension with cushioning to make the ride smoother. It probably had five road wheels on each side, and three return rollers. The hull was built in two sections (at this point the available steel mills couldn't produce a long enough piece of rolled steel to allow for a single piece) and bolted together just to the rear of the fighting compartment. A vertical stiffener was added to strengthen the join. The turret ring had a diameter of 1500mm. The sole example was built from soft steel, 50mm thick on the front, sides and rear and 20mm thick on above and below.

Steering was provided by Cletrac three stage steering gears arranged in series. Each Cletrac stage contained an idler that slowed down the track it was connected to by a fixed amount, produced a different fixed turning circle.

The D.W.1 was followed by the similar Durchbruchswagen 2, which had a modified automotive system. The Krupp turret didn’t arrive in time to be used on either vehicle and they were tested without it during 1939 (see D.W. 2 for more details of the turret). Work then moved onto the VK 30.01 (H), which was authorised on 9 September 1938.

In 1939 one further D.W. chassis and superstructure was ordered from Krupp, to be built from the correct armour, for use as a target hull. By the time this was delivered late in 1940 the design had been changed to more closely match the VK 30.01 neue Konstrucktion, with a different arrangement of armour and a single piece hull.

Durchbruchswagen 1 - History

When comparing the small number of Tigers produced (only 1347) to the more than 120,000 T-34s and Shermans combined, one can appreciate the psychological impact of this model, at least from the Allied tank crew perspective. In its concept laid the very core of the German conception of a heavy tank. Something which targeted absolute excellence in design, combining lethality with the best possible protection, only given to elite crews, all this regardless of the cost. Excellent engineering and training versus numbers underlined all this philosophy and was reflected later in small tactical unit operations.

The Tiger was a formidable machine that pushed the boundaries of armored warfare and forced the Allies to devise better tanks. It powerfully symbolized all the might of the Nazi war machine as dreamt off by Hitler, and later turned through propaganda into a "Wunderwaffe" (wonder weapon) in a mostly defensive war. However, behind the curtain, the Tiger clearly sacrificed mobility and ease of maintenance, but it was always deadly effective (with a 10:1 up to 19:1 kill ratio), earning a capital of fear that was unrivaled during the war. Allied crews found themselves hopeless with their inadequate machines, having to improvise costly tactics to deal with it. The Tiger gave fame to a few WWII tank aces, like Michael Wittman, something unheard of since the life expectancy of a tank crew was always quite shorter than that of fighter pilots.


Its roots can be traced back to January 1937, when Wa Pruef 6 asked Henschel to develop designs for a 30 ton tank armed with a 7,5cm cannon.

The Panzer project was initially called B.W. (Begleit Wagen verstaerkt, reinforced escort tank), implying a similar role as the similarly named Panzer IV design.
The name and intended tactical role didn't last long and on 28 April 1937 it was changed to D.W., Durchbruchswagen, or breaktrough tank.

The design specified a 30 ton tank with 50mm armor all around, pushed by a 300HP MB HL-120TRM to a maximum speed of 35km/h and the 75mm L/24 cannon.
Turret ring was 1500mm, close to Panzer III specs meaning it could accept pretty much the same turrets and guns.

Developed in parallel to the VK 30.01, VK 65.01 was to be a heavy breakthrough tank.
The focus was put on protection, with armor upgraded to 80mm all around to give protection from 5cm cannons, while top speed was lowered to 20-25kmh.

The turret was to share components and general design with D.W/VK 3001, only with thicker armor.
In January 1939 Krupp proposed 3 different guns for the tank: the basic 75mm L/24, a 75mm L/40 and a 105mm L/20.
75mm cannons were preferred due to better performance against bunkers and easier to store ammunition.

The tank was to be truly massive, with a hull that had to be dismounted in 3 pieces in order to fit railway profile.
A Maybach HL224 engine rated 600HP was chosen as power plant, pushing the 65 tons tank at 20kmh.

The project was scrapped after the defeat of France because of bridge restrictions and because Wa Pruef 6 felt that tanks above 30 tons were operationally of limited use.

In june 1940 specifics for a 30 ton class tank were laid, including a 10,5cm cannon as main armament.
Later on, the need of a high penetration weapon resulted in the proposal of mounting the Konical 7,5cm Waffe 0725.

The turret deserves a bit of attention on itself:
In 1939 a turret with 100mm armor mounting a 10,5cm cannon was developed, for a speculative design called A.W., Artilleriewagen.
Unfortunately no design specs survive other than the fact it would have been in the 80 tons class.
As tanks over 30 tons were deemed unsuitable for army needs, the panzer design was scrapped, while Krupp was asked to adapt the turret design (now finalized to use the 10,5cm LEFH 18) to the D.W. chassis.
This was achieved by reducing armor to 80mm front and 50mm sides, with an 80mm thick mantlet.

The D.W./VK3001 was then redesigned to take this improved turret, with increased weight to 36 tons.
The initial design called for 80mm frontal armor, 50mm side armor and was powered by a 450HP Maybach HL 174 engine.

Requests for up-armoring came up soon enough and the design was brought to 100mm frontal armor and 60mm sides, bringing the tank up to 40 tons.
Tungsten shortages brought the project to a halt, especially as the turret ring couldn't support the 88mm L/56 gun, making development switch priority to the larger and heavier VK 45.01 design, the well known Tiger.

This wasn't the death of the plans though, as in 1942 the 7,5cm L/70 was proposed for the design along with the Tiger and VK 30.02, although after this details are lost in Tiger's development.
The only produced VK 36.01 chassis ended up as towing tractor, while the 6 turrets produced for it became part or the atlantic wall.

VK 45.01 (H), aka the Tiger

In May 1941 Henschel was awarded a contract to redesign the VK 36.01 chassis so that it would house a turret suitable to mount the 8,8cm KWK, already developed for the Porsche chassis.
The redrawn specs brought the project to 45 tons, with many components taken from the VK 36.01, while side armor was raised to 80mm.

A new engine was specified, the 600HP Maybach HL 210, while a Rheinmetall turret suitable to house a 75mm L/60 gun, then 75mm L/70 was also considered.
A conversion to use the 88mm L/71 was also planned for late 1942, but never carried out.

Historical VK3001H

today, we are going to have a look at what will happen to the VK3001H in patch 8.8.

But first, in order to explain the logic behind WG’s decision, we have to have a look at the history of the VK3001H. Some very basic info can be found on the World of Tanks wiki page – the data written in the article are unfortunately quite incorrect.

VK3001H (the ingame designation will most likely be VK 30.01 (H) in order to adhere to Doyle’s system) is further development of the Durchbruchswagen concept. The DW vehicles (DW1 and DW2) were – as their name in German suggests – attempts to create a breakthrough tank (in other words, essentially a heavy tank). On 9.9.1938, it was decided to continue with the DW 30 ton category development. On 19.1.1939, Krupp decided that the new vehicle should be equipped with a 75mm L/24 cannon, the crew should be equal to that of Panzer IV and the tank should have 50mm armor all around. On 31.1.1939, this new vehicle program was renamed to Panzerkampfwagen VI (7,5cm), but the new experimental designation for it was VK30.01 (experimental/tracked vehicle, 30 tons, 1st prototype). At the same time, the old DW projects were renamed to VK30.01 (Alte Konstruktion), while the new VK30.01 was referred to as “Neue Konstruktion” (new design).

Design-wise, it was a classical German tank, with typical Henschel suspension (that would eventually evolve into the Tiger one via VK3601. The roadwheels had torsion bar suspension.

3 prototypes were ordered. The hulls were made by Krupp in Essen and delivered to Henschel in Kassel for final assembly in 1940 (1st hull – 15.3., 2nd – 15.4. and 3rd – 15.5.). Turrets were also ordered and Krupp was supposed to deliver them in 1940. However, these came later and most likely were never installed on any prototype machines. The three prototypes instead had a concrete cube installed instead of the turret to simulate the turret weight. The vehicles were equipped with 300hp Maybach HL116 engines and their maximum road speed was 35km/h.

29.5.1941, first order for 0-series 8 VK3001H tanks was signed. Between October 1941 and January 1942, Henschel also recieved the 8 turrets from Krupp, that were to be mounted on the 0-series vehicles. The first 0-series hull was delivered on 8.8.1941 and 15.11.1941, first 0-series VK3001H (with a mounted turret) was tested in Sennelager. This first 0-series VK3001H was by no means finished however (some components were missing) and it was sent back to Henschel. The last hull was delivered on 10.11.1941 and the last turret on 21.1.1942. Maybach also built 18 engines in total for the VK3001 between 1941 and 1943.

On 30.1.1942, based on the preliminary tests (which did not show the vehicle in very positive light), it was decided to reduce the amount of the 0-series tanks being built to only 4 vehicles, which were built in March (2) and October 1942 (another 2). These tanks were sent to training units and were used for crew training.

The armament (which was still the 75mm L/24, quite insufficient for the 1942 battlefield) was also discussed – Krupp proposed on 7.10.1941 following options to the Waffenprüfamt 6:

- 75mm KwK L/34,6 (prolonged version of L/24)
- 50mm KwK L/50
- 50mm KwK L/60
- 75mm Waffe 0725 (which WoT players will know as 75mm Konisch on VK3601, but it was shown later that this cannot be installed).

WaPA 6 responded in the sense that they’d like the 75mm KwK 40 L/43 installed. Krupp replied that in order to do that, either the gun would have to be modified, or the turret would have to be bigger. In January 1942, the re-arm project was scrapped.

Two hulls were subsequently used to build the two 128mm tank destroyers 󈫼,8cm Kanone 40 L/61 auf VK 30.01(H)”, known as “Sturer Emil”. Additional turrets, that were already manufactured before the 0-series VK3001H project was reduced, were actually used for fixed emplacements in France (Atlantic Wall).

The remaining machines were used for crew training and testing various equipment until the end of the war, when they were scrapped.

VK3001H in World of Tanks

Now, you are probably already seeing already how unhistorical the VK3001H is in the game. The problem also is the reliability of facts. Rarely have I encountered so many contradictory messages, so I will rely on Jentz and Doyle in addition to Spielberger.

In the light of the vehicle’s history, it should be no surprise that being the successor of the DW series and the predecessor of the VK3601, this vehicle was spiritually (if not weight-wise) destined to be a heavy tank. Its armor and speed were made to fit this role, as you will see further.

Let’s start with the hull armor. Currently, the VK3001H (in an effort to make it into an agile medium tank, something it was never designed to do) is underarmored. In real life, it had 50mm armor all around (with the exception of certain frontal and rear armor heavily sloped parts, which were only 35mm thick). Why 50mm? Because in 1941, 50mm was believe to be an adequate protection from the 37mm L/46 PaK anti-tank gun, which was taken as some sort of baseline for tests. So, that’s good news for the players – more side armor, while keeping the weight, right? Well, there’s more and you won’t like that.

Expect extreme drop. The real life VK3001H was powered by a 300hp Maybach HL116 engine, allowing it to go around 35km/h (some sources state 25km/h, current ingame maximum speed is 55km/h). For 32 tons, you can expect the drop of power-to-weight ratio to around 9,3 hp/t (50 percent drop). All the current VK3001H ingame engines are not historical. Some might be kept, but most will be dropped.

Expect the stock turret to remain, but the 2nd turret (the Grossturm aka Schmalturm) will definitely disappear (VK3001H couldn’t mount the Schmalturm due to small turret ring). A bit of an info from WG: 2nd turret will most likely resemble the VK3601 stock turret, as that was its historical development. However, due to the loading strain, I’d expect reduced armor, something like 80/60/60, while looking like this:

Now, here’s a pickle. As you can see, the choice is quite broad. However, it’s pretty sure that for tier 5, the Konisch won’t be installed (it couldn’t be even historicall). 75mm L/24, 50mm L/60 could both fit into the stock turret and they are most likely to appear. 105mm L/28 was never considered, so that will not show up I think. The top gun will most likely be the 75mm L/43 (L/48 was never considered, but theoretically could fit too).

So, historical gun choice: 75mm L/24 (stock), 50mm L/60, 75mm L/43 in the 2nd turret.

What you will get is much slower vehicle, more compact than other tier 5 heavies, but packing some punch. With a buffed engine, I believe it might be the most mobile of the tier 5 heavies, but also the most fragile one, with 50mm hull armor (unless they buff it unhistorically).

You are in luck cortz, that I'm a digital packrat and still have the email I sent you with the PDF 5 years ago now. No clue where the PDF is hiding on my computer, although it might have been moved to a flash drive ages ago before I even got this laptop. So I re-downloaded it.

To my knowledge, almost all of them had various issues. Hitler OTL requested additional armor for what became the Panther (30.02 M) and Tiger which also helped balloon the weight as well, so if that's still happening here, it needs to be accounted for. There's the Daimler-Benz VK 30.01 D (and its interleaved raodwheels variant, the VK 30.02 D), but this looks like a T-34 clone to an extent. Not entirely sure what that ended up weighing.

The Henschel VK 30.01 H was a further evolution from the Durchbruchswagen, or Breakthrough tank that had been requested back in the late 1930s. However, there's only 50mm of armor on the front, so while it's close to the weight mark of 30 tons, it's not that capable. Armament was only the 7.5cm L/24 that the Pz.Kpfw. IV used, and Krupp was not confidant in the turret being able to mount anything better without significant modifications.

The VK 30.02 M by MAN, is what evolved into the Panther itself, and was already overweight IIRC, even before the armor increase.

The Porsche VK 30.01 P/Typ 100 was never really built as such, only a single test hull was made. Given the 80mm of frontal armor and the 8.8cm L/56 in a Krupp designed turret (which later evolved into the turret mounted on the Tiger I), I kind of doubt it would have been around 30 tons too.

That being said, before the VK 30.02 M (nobody has found anything on a 30.01 M), MAN was working on something like a standardized version of a Pz.Kpfw. III or IV with torsion bar suspension (the VK 20.01 M), and its improved version (with a different drive train) in August or so of 1941. By November, the vehicle had been redesigned with sloped armor due to experience against Soviet tanks. Both versions had 50mm of armor, with the sloped variant having 50mm at a 55 degree angle. There is also some speculation that this redesigned vehicle might by the mythical VK 24.01 M mentioned by MAN postwar. So if the weight were to be increased to 80mm or so, and using say the Pz.Kpfw. IV's turret with the 7.5cm L/43 or L/48, you would probably have a smaller Panther-like vehicle relatively close to 30 tons, which is also keeping with German vehicles being heavier than they initially started out being designed.

Panzer IV mit Schachtellaufwerk

Post by Jarnob » 30 Oct 2015, 22:05

i have this new photograph in my collection with a very interesting setting.
At first i thought it was a 'fahrschule' - but looking closely it all seem different tanks.
One tank is very interesting in particular: it looks like a Panzer IV Ausf. E mit Schachtellaufwerke.
As far as i know there are no photographs of this tank?
I can not find any photo online or in one of my books. can anyone confirm?

Besides that tank others are visible:
2x Panzer 38 with open engine hoods
2x Panzer III - one light coloured, one dark coloured (no. 132)
1x Panzer I fahrschule (no. V12)
1x Panzer III fahrschule (?) (no. V17)
1x Panzer IV berge ? (no V..)

Does anyone recognizes the location? Can't find that one neither.

in the book "Die deutschen Panzer 1926 - 1945" I could find some information to this vehicle:
"The type "Durchbruchswagen/DW 1", developed at the beginning of the year 1937 by the firm Henschel, had a similar appearance to the Panzer IV with a weight of 30 tons. There were tested fundamental modifications of the "Fahrgestell". The "Schachtellaufwerk" was now tested the first time."

Re: Panzer IV mit Schachtellaufwerk

Post by Jarnob » 31 Oct 2015, 10:46

but it seems that these "Durchbruchswagen" all have 3 return rollers - like Panzer III's.
The panzer on my photo has 4 returnrollers - like a panzer IV.
Besides that it has 8 main (overlapping) roadwheels - not 7.
So ireally think it has to be an experimental Panzer IV

Spielberger (page 12) gives the official designation of the vehicle as VK 2002 (MAN) whereas the Krupp prototyp had the designation VK 2001 (K).

I checked some of my other literature about the Pz IV, panzer rarities and german panzer tracks. None of the books has a photo, some don't even mention the VK 2002.

Well on page 257 of the original Begleitwagen book we have Hilary Doyle’s drawing, dated 1994, which is of a relatively normal Pz.Kpfw.IV Ausf.E with four return rollers. But the Wheels are the larger ones in Schachtellaufwerk configuration just as we see in the photo.

In the history among other things it mentions one such vehicle with Chassis Number 81005 was at the Schule Fuer Heeresmotisierung in Wundsdorf in December 1942 being used as a test vehicle. Jarnob’s great photo just proves the work, from primary sources, of these masters of Panzer History.


I号B型坦克:一号A型的风冷式柴油机存在严重的缺陷,因此1935年德国武器局命令使用LK B2 样车和一号A型的部件开发新的型号,在换装了马巴赫液冷式汽油机后,定型为一号坦克B型。B型的车体加长,发动机盖改为纵置式,每侧有5个负重轮(后4个装在平衡架上)和4个托带轮。从1935年8月至1937年6月共生产了675辆B型。其中部分车辆改装了向上排气装置并加上了空气滤清器,适合于热带气候,它被称为一号Tp坦克并配属非洲装甲军。

D型 德国武器局还计划试验性地发展一种一号“重装甲步兵突破坦克”,顾名思义就是牺牲部分机动性,带有厚重装甲用来掩护步兵冲击敌军要塞的支援坦克。 1940年在一号A型坦克和VK601的混合基础上开发出VK1801样车,它也称为一号D型,由于拥有重装甲而达到20吨的重量。

而德国的古德里安在富勒《装甲战》思想的基础上对装甲兵作战理论进一步发展,提出了坦克集中应用突破敌防线的作战思想。简而言之就是利用大规模的装甲部队担任尖刀作用,在战役层面打开战役缺口。尔后利用其机动性优势迅速向敌后方进攻,瘫痪敌后勤指挥系统,由摩托化步兵跟随其后填补战场空缺,最后装甲部队回应配合步兵完成对包围圈内敌人的围歼,这也是二战期间德军所采用的战术思想,并与之配合发展了1号、 2号 、3号 、4号、 5号黑豹、 6号虎式 、7号虎王共7型主力坦克。

在1号和2号坦克发展的同时,古德里安就指示各军火公司研制一种15吨级装备37或者50mm火炮的中型坦克作为未来装甲部队的主力坦克。1937年5月陆军部选中了奔驰公司的设计方案,定型后的坦克被命名为PZKPFW3型,简称3号坦克。3号坦克自1939年入役到战争结束各种改进型号多达12中,其中A B C D为实验型号,产量很小。1939年开始生产的Z型是初生产型号,Z型后期装备一门50mm短管火炮,是入侵波兰的主力。1941年德军又开发了F. G. H三种型号,它们和J 型早期型都装备了50mm或37mm的火炮,1941年至1943年又增加了J G M N四种型号。除了N型和J型早期型,其他型号都装备一门50mm长身管火炮,N型装备一门短身管75mm火炮。截止战争结束3型坦克各种型号共生产了6000余辆。

The Panzer I was a light tank produced in Germany in the 1930s. The name is short for the German Panzerkampfwagen I ("armored fighting vehicle mark I"), abbreviated PzKpfw I. The tank's official German ordnance inventory designation was SdKfz 101 ("special purpose vehicle 101").

Design of the Panzer I began in 1932 and mass production began in 1934. Intended only as a training tank to introduce the concept of armored warfare to the German Army, the Panzer I saw combat in Spain during the Spanish Civil War, in Poland, France, the Soviet Union and North Africa during the Second World War, and in China during the Second Sino-Japanese War. Experiences with the Panzer I during the Spanish Civil War helped shape the German Panzerwaffes' invasion of Poland in 1939 and France in 1940. By 1941, the Panzer I chassis design was used as the basis of tank destroyers and assault guns. There were attempts to upgrade the Panzer I throughout its service history, including by foreign nations, to extend the design's lifespan. It continued to serve in the Spanish Armed Forces until 1954.
The Panzer I's design history can be traced to the British Carden Loyd tankette of which it borrowed much of its track and suspension design. After six prototype Kleintraktor were produced the cover name was changed to Krupp-Traktor whereas the development codename was changed to Landwirtschaftlicher Schlepper (La S) (Agricultural Tractor). The La S was intended not just to train Germany's panzer troops, but to prepare Germany's industry for the mass production of tanks in the near future a difficult engineering feat for the time. The armament of production versions was to be two 7.92 mm MG 13 machine guns in a rotating turret. Machine guns were known to be largely useless against even the lightest tank armour of the time, restricting the Panzer I to a training and anti-infantry role by design. The final official designation, assigned in 1938, was Panzerkampfwagen I (M.G.) with special ordnance number Sd.Kfz. 101.[16] The first 150 tanks (1./LaS, 1st series LaS, Krupp-Traktor), produced in 1934, did not include the rotating turret and were used for crew training. Following these, production was switched to the combat version of the tank. The Ausf. A was under-armoured, with steel plate of only 13 millimeters (0.51 in) at its thickest. The tank had several design flaws, including suspension problems, which made the vehicle pitch at high velocities, and engine overheating. The driver was positioned inside the chassis and used conventional steering levers to control the tank, while the commander was positioned in the turret where he also acted as gunner. The two crewmen could communicate by means of a voice tube. Machine gun ammunition was stowed in five bins, containing various numbers of 25-round magazines. 1,190 of the Panzerkampfwagen I Ausf. A were built in three series (2.-4./LaS). Further 25 were built as command tanks.

The Panzer I's performance in combat was limited by its thin armour and light armament of two machine guns. As a design intended for training, the Panzer I was not as capable as other light tanks of the era, such as the Soviet T-26. Although weak in combat, it formed a large part of Germany's tank forces and was used in all major campaigns between September 1939 and December 1941. The small, vulnerable light tank would be surpassed in importance by other German tanks, such as the Panzer IV, Panther, and Tiger nevertheless, the Panzer I's contribution to the early victories of Nazi Germany during World War II was significant. Later in that war the turrets of the then obsolete PzKpfw Is and PzKpfw IIs were repurposed as gun turrets on specially built defensive bunkers, particularly on the Atlantic Wall.

World of Tanks Sandbox: Tech Tree Changes in More Detail

World of Tanks Sandbox New Balance has brought big changes to seven of the eleven tech trees. The major changes will happen in the USSR, USA, Germany, France and the UK, but almost all nations will have vehicles relocated from their Tech Tree. In total, 92 vehicles will be relocated.

The simplification of tech trees it’s way to make the game easier to new players by giving them fewer choices and make focus on moving up to Tier V or Tier VI much quickly. Existing players won’t lose any vehicles, researched or not-researched because any vehicle from Tier II to V that isn’t in the Tech Tree anymore, will still be available to anyone who wants them, just in a different way. For existing players, the following will happen:

  • Owned vehicles present in the garage, will stay there.
  • Unowned vehicles will be available in a new area of the shop called Collection Vehicles.
  • Vehicles will only cost Credits, no further need to spend Experience to unlock them.
  • All vehicles will still have modules to be researched.

The main advantage will be the fact existing players can just buy any vehicle outright without the need to research them, and of course, spending no experience at all. For new players, the main difference is that these vehicles are only available after a Tier VI vehicle is researched, before that they won’t be able to buy them.

Tier I to V vehicles are not classified as Reward or Premium vehicles, they are still Regular vehicles, meaning while they will have Elite status, they won’t give any additional bonus. Here’s a list of all vehicles that will be relocated by nation and comparison images of the Tech Tree.

What happens to vehicles of Tier VI and above?

It’s still unknow what will happen exactly with any vehicle of Tier VI and above. There are in total 13 vehicles that will be relocated and there are no plans to when and how they will be back. One thing is certain, if you have them in your garage already, you get to keep them, so its always worth grinding and buying these if you haven’t already. Here’s the list of vehicles:

U.S.S.R Germany USA France UK China
– KV-85
– KV-13
– T-62A
– VK 30.01 D
– Jagdpanther II
– T21
– M4A3E2
– T71 DA
– AMX 30
– AMX 30 B
– Churchill GC
– Sherman Firefly
– 113

All the above vehicles have been converted into Elite Reward vehicles, this means they don’t have any modules to be researched and they give the same bonus as other Reward vehicles: More Free Experience and Crew Experience, Free transferring crew members without penalty and they lost their Credit price and received a price in Gold. They won’t give more credits per battle, as they are not Premium vehicles.

At the moment, any information about how they will be available is pure speculation, but I do have concerns that Wargaming is going to try to capitalize on these vehicles. By capitalize, I mean profit on them, by maybe making them available on Black Market Auctions, Bond Shop or some sort of Reward Marathon. If you don’t want to have to earn them later on, it would be wise to invest your time grinding these vehicles.

Overall Opinion

While I can see what is tried to be achieved with these changes on the lower Tier levels, I’m not keen on having them implemented. The main reason is that I strongly believe that the simplification won’t have the effect Wargaming is expecting to have. World of Tanks is not a new game anymore, it’s almost 10 years old, Wargaming should be focusing on maintaining the current player base, not making the game much simpler so it’s easier to get new players and in the process alienate the old player base.

Let’s face it, who hasn’t heard of World of Tanks by now? And if they aren’t playing it, are they really going to start?

Second, why remove vehicles above Tier VI, especially Tier X and a respective mini-branch? Yes, the Tech Trees needed some rework, but mainly was some tanks to be moved around and some links to be removed or created, not the removal of 92 vehicles from the tech tree! I really don’t see the point of removing the AMX 30 and AMX 30 B, or the T-62A or the 113, these tanks were there to give players a choice, not to just fill a place.

Together with this, the whole spectacle of not knowing when and how these will be available is quite unacceptable. To add into, Wargaming has no plans to return any Experience used to unlock these vehicles back to players. At the moment in the Sandbox, all the experience ended up in some of the removed vehicles waiting to be converted into Free XP. If this is Wargaming plan, isn’t that yet another way to capitalize on players, expecting them to buy Gold and use it to convert a huge amount of experience?

When I first heard that Wargaming had plans to revisit the Tech Trees, back at Tankfest 2017 in a conversation with Thaine Lyman, I was under the impression that useless modules were going to be removed, some tanks would be moved around and links between branches were going to be updated to make some sort of sense. Thaine is long gone and what we got, was the relocation, that for me is the removal, of 92 vehicles, some of them converted into Reward vehicles that no one seems to know how and when we can get them, and the useless modules are left intact? I understand that it would be hard work to rebalance all these low tiers, but is removing them from the Tech Tree really a solution or is it just kicking the can down the line and pretend the problem doesn’t exist anymore?

To me, these changes are pure laziness and burying the head in the sand from Wargaming, in hopes they won’t have to do anything about it after. Let me know your thoughts in the comment section.
