FAKE.FAKE.FAKE.FAKE

E-100 "Krokodil"


Another very popular "design", that keeps appearing from time to time. This time it doesn't come from a computer game, but probably from some modeller. Even this vehicle has fake history accounts on the internet, that can confuse people. The main reason it is so popular is because it looks great, however, it was never concieved by German engineers. Sorry. The whole "Jagdpanzer E-100" business was a pretty odd affair anyway - basically it was just a thought design - some guy somewhere had an idea that it would be cool to put a huge gun on the E-100 chassis and make it a superheavy tank destroyer. Nothing more, not even the type of the gun was decided. Mr. Hilary Doyle (a German tanks expert) confirmed this is a fake - the only thing that actually WAS real was a part of the weapons mount, but that didn't even fit the E-100 hull. The Jagdpanzer E-100 currently in the game is a result of what Wargaming thinks it might have looked like - the most realistic one at least. As was again confirmed by Mr. Doyle, the Krokodil wouldn't work for various reasons (the weight distribution, suspension strain... there are many threads about this on WoT forums). Either way - sorry, we won't see the Krokodil in the game.

The Mouse that Hunts
Posted on August 15, 2014 by Silentstalker

Hello everyone,

a mouse is usually a small animal being hunted instead of doing the hunting… but – what if we gave it the teeth of the crocodile?

Why is it needed? Where would it go?

Let’s start from the beginning. There are basically two reasons why a new German tank destroyer would be needed.

First:

Some time ago, the Waffenträger E-100 line was implemented. After some time, it was found out that the Waffenträger E-100 is far from ideal. While fragile, it was also overpowered and with its phenomenal firepower, it was able to chew through practically any tier 10 vehicle within a single autoloader cycle. That of course was not exactly an ideal situation and in 9.2, WT E-100 was nerfed, but it still remains one of the most feared predators on the battlefield.

Apart from being overpowered, it has another issue – it’s completely unhistorical – in other words, a Wargaming-made fake. There have been some hints as to the willingness of Wargaming to replace something else, IF a suitable candidate is found. So far, it was not.

Second:

As you probably know, there have been tons of historical Waffenträger designs in the past. Most are based (such as the ingame RhB) on the Panzer 38t or 38d suspension, while others are based on either the Panzer IV (also in the game) or the Panther. Generally speaking, these Waffenträgers could be built into a line, ranging from lower tiers, with tiers 7 and 8 covered by 38t/d based WT’s and tier 9 by a Panther Waffenträger. These vehicles are all historical and I covered them in several previous articles. The problem with such a line is, there is no tier 10 for it. Even the best Panther Waffenträgers (carrying no better weapons than the ingame Panzer IV WT) would fulfill the tier 9 slot unfortunately, without some serious unhistorical buffing at least – and even IF a WT Panther was dragged to tier 10, it would have to fight with pure stealth, its chassis being very fragile compared to other tier 10 vehicles. And more “invisible sniper from bushes” vehicles is not exactly what this game needs.

The Mouse That Hunts

Probably the most obvious candidate for either WT E-100 replacement or new tier 10 vehicle would be the Sturmgeschütz Maus, also (incorrectly) called the Jagdpanzer Maus, or Jagdmaus. It was a historical competing project to the Sturmgeschütz E-100, designed by Porsche. Note that the Jagdpanzer E-100 (or Jagdpanzer Maus) is not historical, the vehicle was intended to be a heavy assault gun, not a tank destroyer – so if you ever read anywhere about the StuG E-100, it’s the same project as the Jagdpanzer E-100. The official designation of the vehicle was 15/17cm Sturmgeschütz auf Mausfahrzeug. It is covered in Panzer Tracts 6-3, page 48.

It was a very short-lived project (from May to July 1944, when Hitler stopped the superheavy development, facing the crisis on the eastern front). It seems that a small-scale mockup was possibly made, but no drawings or photos survived the war.

What we do know about it:

- it was to be equipped with 15cm L/63 or 17cm L/53 gun
- Porsche wanted a flak turret on the vehicle, this was declined due to the fact the vehicle would be escorted by an AA tank
- Porsche design in May 1944 was only in concept stage, it was judged too tall, “exceeding the railroad profile”
- Porsche later on wanted a 3cm flak turret on the vehicle at the expense of gun recoil
- Vehicle was to carry 85 rounds of ammunition
- a gun, considered for the E-100 competitor was also 15cm L/68, that however was a Krupp thing

What we do NOT know about it:

- how it looked, dimensions
- how thick was its armor
- the gun performance
- the engine that was to power it
etc.

As you can see, very little is known about the project, apart from the fact it existed. If it was to be – say – implemented into World of Tanks, the developers would have a lot of potential room to operate. It however must be noted that any such implementation would have to be marked specifically as “artist’s impression”, as there is no way of knowing how the real vehicle would have looked like. Still, better than WT E-100 – and this is where the real fun begins.

Crocodile’s Teeth

trump1_35jagdpanzere100

This is the Jagdpanzer E-100 “Krokodil”. It’s a notorious fake, that appears every now and then on the internet. No such vehicle was ever planned and the author of this look was not a German engineer, but a modeller, specifically the Trumpeter company. Alternative looks of the “Krokodil” exist on the internet, they are all fake. Nevertheless, at one point (a long time ago), Krokodil was actually seriously considered for implementation in World of Tanks by the developers. There are however two serious issues with the vehicle:

- it’s unhistorical: even if the Sturmgeschütz E-100 (not Jagdpanzer!) existed, it would not likely be of this setup. There are tons of issues with the frontal gun layout: the gun is long and the vehicle was of titanic weight, exceeding the capabilities of WW2 level metallurgy. Sure, ISU-152 worked with the frontal gun, but the gun was shorter and most importantly, the vehicle weighed 47 tons, not 150. The frontal part of the suspension would be overstressed, it would be difficult to maneuver etc. – there is a lot of problems with that design and that was why Wargaming decided to implement the rear-casemate version, that is more realistic. The Wargaming version of Jpz E-100 is what Krupp likely intended it to be – that, or an oversized Jagdtiger with mid-casemate.

- it’s copyrighted: yep, it’s art, so it’s protected by law. Unless WG bought the rights to this design, well… too much hassle I guess.

But… there is a way. What if Wargaming made the StuG Maus into some sort of KrokoMaus? Noone knows how it looked. The short version is: make it frontal casemate as the picture above, give it the 15cm L/63 and Maus suspension. And there you have it, the Maus with some nasty teeth.

The Design

As I mentioned it above, noone knows how the StuG Maus looked like. While it is historically unlikely that the German engineers chose the frontal casemate variant (the Maus design would require some serious overhaul in this case), it is certainly more attractive design. What I am thinking is something like this.

krokomaus

The goal would be to create something lighter than the Jagdpanzer E-100 in the game, but with some nasty punch of the 150mm gun.

The armor – well, nothing is known, so it’s a purely balance measure. I’d suggest something that would give it roughly the same level of protection as the Soviet tank destroyers have, so somewhere between 200-250mm effective armor with LFP weakness. Sides would be weaker, but the sideskirts could compensate for some of that. Alternatively, the armor could be significantly lighter for increased performance and gun soft stats.

The gun – 150mm L/63, its historical performance is not known, so anything goes. I would suggest something like:

Penetration – 290/350/90
Damage – 750/750/1100
Accuracy – 0,32
Aimtime – 2,5s
RPM – 3,33

The mobility – probably Maybach Neues Projekt engine, 1200hp in the game. The actual performance depends on the weight of course, but I’d put it somewhere between WT E-100 and Jpz E-100.

Naturally, the camo factor of this beast would be mediocre (we don’t need invisible TD’s).

So, what do you think?

StuG E-100 "Krokodil" (fake)
publicado a la‎(s)‎ 19 sept. 2014 10:16 por ACB el Mutie   [ actualizado el 19 sept. 2014 15:27 ]

Internet es una buena fuente de información, pero muy a menudo se filtran imágenes y textos de vehículos que nunca existieron. Modelistas y aficionados los disfrazan con una buena historia para que parezcan creíbles. En este caso hablaremos del StuG E-100 "Krokodil" (cocodrilo). Antes de explicar por qué no es real, pongamos una foto del vehículo en cuestión:

Al igual que ha habido muchos diseños que no salieron del papel, del StuG E-100 no hay imágenes ni bocetos, sólo es citado en algunos textos como intento de crear un cañón de asalto (StuG) superpesado basado en el chasis del carro de combate E-100. Dada la falta de diseños, la marca de maquetas Trumpeter diseñó este modelo que rápidamente tuvo una buena acogida entre los aficionados a los carros de combate alemanes.

El diseño es bonito en su forma, similar al JagdPanther. Sin embargo, este diseño iba a ser mucho más pesado que su hermano pequeño y la instalación de un cañón tan grande junto con un blindaje frontal tan pesado, haría que la suspensión estuviese sobrecargada. La solución más normal sería instalar el cañón en la parte trasera, lo cual facilitaría el reparto del peso del vehículo entre la parte delantera y la trasera.

La información que tenemos sobre la existencia de planos del StuG E-100 proviene del siguiente extracto sacado de Panzer Tracts No.6-3":

El 9 de mayo de 1944, durante una reunión con Krupp en Obering, Schmidt (Porsche) presentó un juego de dibujos de unos 15 cm L/63 y 17cm L/53 sturmpanzers creados por Krupp que iban a ser desarrollados por Porsche en su Maus en competición con el E-100 de Adlerwerke.

Sin embargo, dichos planos nunca transcendieron. Es posible que sean documentación clasificada y por eso no son accesibles actualmente, pero eso es algo que no sabemos, por lo que el dibujo del "krokodil" es totalmente inventado. No hay una sola publicación seria que pueda avalar dicho proyecto y de hecho no aparece en ningún libro de Hilary Doyle, Thomas L. Jentz o Walter J. Spielberger, los mayores historiadores sobre carros de combate alemanes. De hecho, el propio Hilary Doyle afirmó en una entrevista que varios vehículos que pululan por internet no existieron jamás.

Wargaming to reconstruct Maus…
Posted on April 11, 2014 by Silentstalker



Honestly, I am not sure whether this is real or some sort of PR or elaborate trolling. Reconstructing a tank of this state (especially something as unique as Maus) is very, very expensive. And I don’t mean “looking for Spitfires in Burma” expensive. We are talking about several million Euro expensive (only the engine rebuilt from scratch – IF that is even possible – I would estimate at 3 million Euro – this is based on the fact that reconstructing a “big cat” engine in the past costed 1 mil GBP and that was not as exotic as this stuff).

But if they make it, holy crap.

y lo que dijo el museo


Kubinka Museum says “Fuck You” to Maus Restoration Hype
Posted on May 12, 2014 by Silentstalker

Hello everyone,

this is actually pretty entertaining. Looks like things will be not as “hot” with the Maus restoration as Wargaming would have the world believe. At first, I ran into this post in the LJ community, reprinting the Kubinka Museum VK status.

For those who do not know – VK means “Vkontakte”, it’s basically a Russian Facebook service, a social network largely used in the CIS. Kubinka has a webpage there and as you can see, it’s quite popular (over 6000 “likes”). Yesterday, a status appeared on the webpage (by then it was still accessible to outsiders and not a “closed group”, you can see that in google cache):

kub1

It says:

“Central Museum of Armored Vehicles” of the Ministry of Defense of Russian Federation officially states, that the information of the restoration works on the tank “Maus”, which appeared in various mass media, is not true. It’s a perspective project, which is in the state of negotiations and approval. The Museum staff is outraged by the insolence, ignorance and absolute lack of patriotism of the employees of the aforementioned mass media.

The Museum will never prioritize the restoration of the German tank “Maus”, or any foreign tank to any of the Russian military anniversaries, let alone the Day of Victory celebration, which is the most important celebration for us. The restoration of the German tank is not “a great honor for us” as the journalists write, but a simple planned work. Restoration works on this projects, if they happen at all, will be carried out following the order of work.

Currently, the Museum, exclusively on its own, restores the legendary Soviet tank T-35 to be ready for the 70th Anniversary of the Great Victory, for which we are rightfully proud.

Furthermore, the information about our exclusive partnership with company Wargaming is not true. An “exclusive” partnership with any organization is out of the question, as the Museum is a public institution, that in the past cooperated and always will cooperate with all organizations and institution for the good of our Motherland within the framework of joint projects and programs, aimed at the Museum development, patriotic education and prevention of historical facts falsification.

With kind regards
Administration of the Museum”

This harsh text is apparently a reaction on earlier news articles (here for example), bombastically claiming the exclusive partnership of Kubinka with Wargaming. Bravo, WG PR department!

Shortly after this post, the group was closed for public (since this angry post got widely reposted on Russian forums and blogs) with one last message:

kub2

“Dear friends, the Museum is asking for your help with maximal spreading of the news, posted below (SS: the angry post). Thanks to the companies, that sponsor the spread of false information in mass media, the Museum loses its credibility and respect of its visitors and of all those, who follow our work. Thanks in advance! With kind regards, the group administration”

Looks like the future of the Maus restoration future is as gloomy as the proverbial Teutonic genius… if it will happen at all.

Wargaming Patents E-50M
Posted on November 19, 2014 by Silentstalker

Hello everyone,

we all knew that the E-50M is a Wargaming-invented fake, but now, we have a legal document to prove it! Smile Many thanks to Alpha_Dude for finding this info.

On 24.7.2012, Wargaming filed a patent application (no. 29/427,959) to protect the E-50M design. The proceedings took more than two years and on 9.9.2014, the patent protection of the E-50M design was approved. It’s now protected for 14 years.

Funnily enough, the “inventor” of the patented vehicle is noone else than Sergei Burkatovskyi (aka SerB). There you have it, SerB is officially the inventor of the E-50M Smile

The legal document follows:








wargaming creo el e-50m para llenar la rama del e-50 con un tanque lo mas parecido a la realidad



E-50 Ausf. M

Here it gets more complicated really. E-50 existed, at least as a concept (mind you, it was not a "Wunderwaffe" superdesign, the aim of the E series was to streamline and simplify the tank production as much as possible). E-50 Ausf. M however is a Wargaming fabrication. For all intents and purposes it's a fake, but a "realistic" one. At the end of the war, the (civillian) designers started coming up with all sorts of stuff. One of the things they came up with was the powerpack engine concept (in which the engine and the transmission form one block, that can be easily replaced on the field - well, at least more easily than the earlier engines). This would require the turret to be moved to the front and various other modifications. The Germans never did such a thing, this was done by Wargaming with the help of Yuri Pasholok and Hilary Doyle. So, it's a sort of half-fake. It never existed, but it's realistic.

O-I by Seon Eun Ae
Author: Seon Eun Ae

The O-I (オイ車 Oi-sensha) was a super-heavy tank prototype designed by the Imperial Japanese Army during the Second Sino-Japanese War after the Battles of Nomonhan in 1939. The O-I is one of the Second World War’s more secretive tank projects, with documentation regarding the tank being kept private for over 75 years at Wakajishi Shrine, Fujinomiya. Surviving files have been purchased by FineMolds Inc., and publicly previewed in mid-2015. The multi-turreted 150-ton tank was designed for use on the Manchurian plains as a supportive pillbox for the Imperial Japanese against the Soviet Union. The project was disbanded four years after the initial development began, deemed unsatisfactory for continuation in 1943 after the lack of resource material for the prototype.
History and development

After 1939, the Imperial Japanese Army quickly came to realize that previous forms of mechanized warfare were proved inefficient after their defeat at Khalkhin Gol.

Development of the super-heavy project was spearheaded by Colonel Hideo Iwakuro, the head of the Ministry of War of Japan (陸軍省 Rikugun-shō). Iwakuro opposed Japan’s advances towards the Soviet Union in 1939, and with the Japanese defeat, he decided to initiate a project to construct a heavily armored tank capable of withstanding large-calibre field cannons. Iwakuro assigned Colonel Murata of the 4th Technical Research Group to design and construct the super heavy tank in 1939. Colonel Murata noted Iwakuro’s words as described;



「満州の大平原で移動トーチカとして使えるような巨大戦車を作ってほしい。極秘でだ。」
“I want a huge tank built which can be used as a mobile pillbox in the wide open plains of Manchuria. Top secret.”


「今の戦車の寸法を2倍に延ばして作れ。」
“Make the dimensions twice that of today’s tanks.”


The 4th Technical Research Group began designing the super-heavy vehicle throughout 1940, attempting to meet Colonel Iwakuro’s vague instructions on the ultimate goal of the project. By March 1941, the research group had finished initial tank design and was ready to begin construction. The following month, a group of pre-selected engineers were chosen to partake in the building of the super-heavy tank. One recorded engineer was Shigeo Otaka, who stated they were sent to the 4th Technical Research Group’s previous headquarters in Tokyo. There, they were guided through a barracks containing multiple small fitting rooms, where they were to conduct meetings and reports on the progress of construction of the super-heavy vehicle. Towards the end of the barracks facility was a fully-enclosed room devoid of windows, with soundproofed walls to prevent external personnel from overhearing discussions related to the project. Each officer present possessed a portion of the project’s blueprint, which, when assembled, projected the full design of the tank, labelled "Mi-To". The name originated from a collection of the Mitsubishi industry and the city, Tokyo; given to the vehicle to uphold secrecy of the tank’s project.


Colonels Murata and Iwakuro


The chosen engineers voiced their concerns regarding the Mi-To’s design noting that previously, the largest-sized Japanese tank had been the prototype Type95 Heavy in 1934. Issues that had been noted with heavy tank experiments in the years preceding the Mi-To showing Japan’s generally unsuccessful testing on multi-turreted vehicles exceeding the weight of standard armored vehicles. However, with the threat of a second Russo-Japanese conflict becoming more apparent, the project continued despite the engineer’s doubts on the size and mobility of the vehicle.


Four engineers who survived to record the dealing had with the project


On April 14th 1941, the engineers began the construction of the Mi-To under secretive means. This entailed privately-made mechanical parts and equipment being shipped to the construction zone. Colonel Murata’s original concept was to complete the super-heavy tank three months after the initiation of Mi-To’s construction. This, ultimately, did not come into fruition; as technical issues on the project began to arise. Due to the limitation on material consumption by the government, the amount of parts that could be secretly shipped-in began to dwindle. By the first month of construction, essential construction resources had been depleted and the issues with the vehicle’s cooling system further caused delays. The construction of the Mi-To was postponed until January 1942, a delay of nine months.


After the Mi-To’s construction was resumed, the hull was completed on February 8th 1942. The tank had reached near-completion and was being prepared for mobility testing. Mitsubishi built the four turrets for the tank in May of the same year. Initial assembly of the tank’s armament took place soon after the turret’s superstructures were completed. However; the project once again did not have the necessary resources needed for the few remaining parts required for the final assessment. Due to this, the primary turret was removed as it lacked a 35-millimetre-thick roof plate, which had not yet arrived. Thus, the project was put on standby, until further development could continue. The total weight of the vehicle at the time was 96 tons, due to the lack of remaining structural plates and absent 75mm bolted-on armor.


O-I documents previewed by FineMolds

The date on which the construction of the tank resumed is unknown, although active testing of the tank was scheduled for late 1943. The tank was unveiled to the Imperial Japanese Army’s highest command in 1943, and received a name change to O-I. This followed Japanese naming convention (O translating to Heavy, I for First, making it "First Heavy") that was standard. In his place was Lieutenant Colonel Nakano, Murata's assistant and colleague. Tomio Hara, head of the Sagamia Army Arsenal, was also present. Following the demonstration, senior officials within the IJA requested that field trials begin in August of the same year. The tank was disassembled at 2:00 AM one night in June of 1943 and sent to the Sagami Army Arsenal in Sagamihara, 51 kilometres from Tokyo. The vehicle arrived at the depot in June, and was reassembled and tested on the 1st of August.

On the day of the trials, the O-I performed satisfactorily until the second hour of the tests. While manoeuvring on off-road terrain, the tank sank into the ground by up to a meter; attempts at traversing the hull to extricate the vehicle proved fruitless, resulting in further sinking due to the vehicle’s suspension coils compressing. The tank was eventually towed out, and further testing was continued on concrete. However, the earlier damage to the suspension resulted in vehicle’s movement damaging the concrete, which in turn, further damaged the suspension bogies to the point that further testing could not continue. The trials were postponed, and later cancelled the following day.


Nevertheless, the trials conducted at the testing field were considered to be a success, and the vehicle was deemed ready for use in spite of its flaws. The engineers began disassembly of the tank on the 3rd of August due to resources being limited and the inability to maintain the tank in the field. Disassembly of the tank was completed on August 8th. Two days later, the engineers noted in a log that they were to inspect the parts and conduct research to fix the issues the O-I would face.


The fate of the O-I after its field-trials which took place on the 1st of August is unclear. Russian reports claim the Japanese were in possession of a wooden O-I mock-up mounting a Daimler-Benz DB 601A engine in 1945, however other sources point to the scrapping of the remaining parts of the same year. The remains of the O-I reside at the Wakajishi Shrine, with a track link of the prototype still present.

Design
The O-I was conceived out of the necessity to produce an armored vehicle capable of withstanding modern weaponry being able to return fire with similar firepower. The O-I was designed to act as a mobile pillbox, supporting infantry and mechanized groups along the border of the Soviet Union. The tank had a length of 10.1 meters, width of 4.8 meters, and a height of 3.6 meters. The dimensions of the vehicle closely matched those of the Panzer VIII Maus. The tank was envisioned to have a standard thickness of 150 millimeters front and rear, in order to protect against common anti-tank weapons of the time, yet it was constructed with armor 75 millimeters thick. However, an additional armor plate could be bolted on to bring the total thickness of the armor to 150 millimeters. The use of additional armor allowed for ease of construction and transportation, while also providing the tank with additional defense. Side armor on the hull superstructure was 70 millimeters thick. The additional armor plates were 35 millimeters thick, but armor surrounding the suspension was only 35 millimeters thick. This made the tank’s theoretical armor on the side 75 millimeters. There were eight wheel-supporting beams located on both sides of the suspension area which added an additional 40 millimeters of armor to specific locations on the side of the O-I. 40 ladder pieces were placed around the tank to provide crew with the ability to climb onto of the vehicle with ease.


The two 47mm cannons used in the two frontal turrets were also modified to fit the armor layout of the tank. The weapon’s barrels were reinforced with steel to secure them to the tank, due to the standard gun not adequately fitting into the turret.

The tank was both designed and built with two inner armor plates to divide the interior into three sections; walls with two doors each and an ultimate thickness of 20mm. This allowed the crew and modules to remain relatively safe while the structure was kept safe with supporting stands. These supports allowed the interior armor plates to stay stable and also prevented collapse. Inside the O-I were two Kawasaki V-12 engines, both located in the rear, parallel lengthwise, to give room for the rear turret operator and transmission. The transmission copied that of the Type97 Chi-Ha’s, but used larger parts and gears making the total weight heavier. The vehicle had a coil spring system, with eight 2 wheeled boggies, totalling 16 individual wheels.
