The Straussler MBT – Hungarian tier 10 candidate

Author: Karika

Hello everyone!

I’m Károly Németh, a.k.a. Karika, a Hungarian military historian and in this article I would like to share something interesting with you, WoT community members. Today, we will take a look at the Straussler Main Battle Tank, a never before published armored fighting vehicle concept from the Cold War.

Recently I did an in-depth study of its designer, Nicholas Straussler, a Hungarian born British inventor, automotive and military vehicle designer. During this research I have found this rather interesting concept of a tank lying forgotten in the archives of the Bovington Tank Museum.

TL;DR: Here’s tank concept with outstanding mobility, an autoloading 120mm gun and probably paper armor which could be a tier 10 Hungarian TD in World of Tanks.


Disclaimer: I cannot publish the original, not too detailed blueprint for copyright reasons, so I created this basic, low polygon 3D model to give you an idea how this tank supposed to look like. This is just my artistic impression of the Straussler MBT, and it is not 100% correct, mostly because of the lack of details at some parts of the blueprints. I used this model to calculate some of the missing characteristics that are not mentioned in the description.

At first, let’s say a few words about its designer.

Nicholas Peter Sorrel Straussler (1891-1966) was born as Straussler Miklós in Isaszeg, a small town not far from Budapest, in the Austro-Hungarian Monarchy. As an adolescent he was sent to England to study and after college, he settled in London as a self-employed consultant engineer and inventor. In the 1920’s, he patented at least 20 inventions, and soon after, he founded his own company, which constructed collapsible boats and pontoon bridges – for example for the British Army.

In 1933 he got the British citizenship and in the same year, he purchased a small workshop and started to build the prototypes of his first vehicles. Through the 1930’s, he designed and prototyped many prime movers, artillery tractors, trucks/lorries alongside with a few armored cars and tank designs with moderate commercial success. For mass productions, he usually teamed up with larger factories, such as Alvis Ltd. (a British car and aero engine manufacturer) or the Weiss Manfréd Rt. (the largest Hungarian industrial firm at the time) to name a few.

Back in 1932, he laid out the first ever purpose designed armored car of the world, the Straussler AC-1, as every other armored car before that were converted from regular cars or trucks. Most British and foreign armored car designs followed his 4×4, independent suspension with rear engine configuration later on. In the second half of the 1930’s, further developed versions of this armored car design were used by the Royal Air Force in Aden and Mandatory Palestine (Alvis-Straussler Type A), by the Dutch East-Indies Armies and the Portuguese Army (AC-3D) and by the Royal Hungarian Army (39M Csaba) before and during the Second World War.

In the mid 1930’s his own, quite unorthodox wheel-cum tank design was prototyped as well. Different variants of this tank were tested by the British Army, the Soviet Red Army, the Dutch, the Polish Armies, and one was even sent to Japan. At the end, none of these countries accepted Straussler’s tank, mostly due to mechanical unreliability and some design flaws.

A variant of his tank design was built by the Weiss Manfréd for the Hungarian Army too under the name of V-3. This, and its further development, the V-4 were the first Hungarian made tanks, and the V-4 was the first tank on the European continent which performed a river crossing by itself with the help of attachable pontoons, designed by Straussler of course. However, in 1938 the V-4 fall behind the Swedish L-60 light tank (the predecessor of the later Toldi light tank family) during their comparative trials and the V-4 never entered service in Hungary.

During WWII, Straussler ceased to design vehicles – apart from one exception – and focused his genius to solve an important problem: how to make an easily useable amphibious equipment for existing tanks?

He presented his solution, the Duplex Drive or DD equipment for the British Army in late 1940. His idea was to create a canvas screen around a regular tank, held in place by inflatable tubes and metal bracing which enabled the tank to float. This was supplemented with a propeller powered by the engine of the tank to drive it in water.

This was one of the most well-known inventions of Straussler, which became famous during the Normandy landings where a number of Sherman DD tanks swam ashore on D-Day by themselves.


After the war, Straussler continued to improve his DD equipment and in the 1950’s, he patented the Lypsoid tire, which had extremely good off-road capabilities. He also designed a large number of various light, air portable vehicle designs for airborne units. Only one of these designs entered service, which became the FN AS 24 collapsible paratroop trike in the Belgian Army.


Vehicles with Straussler’s Lypsoid tire: the AS 24 (top), a West German FAUN Kraftkarren (Kraka) military quad (middle) and an experimental Straussler-made truck chassis (bottom) with Nicholas Straussler himself on the left.

He also designed a large number of other transport and armored fighting vehicles at this time, but as he was more occupied with the DD and Lypsoid related designs, and because he could not find a sponsor for these projects, none of these left the drawing board. One of these paper designs was the Straussler Main Battle Tank or Straussler MBT, which was designed sometime between 1959-1961. This idea of „the ideal tank” was presented to the leaders of the British Army in 1961, but they were not interested in this rather unconventional and unproven design, and insisted on continuing the existing next generation tank project, which later became the Chieftain main battle tank.

The Straussler Main Battle Tank

If you take a look at the appearance of the Straussler MBT, it’s visible that this ambitious, turretless tank was certainly influenced by the Swedish Strv. 103, but carried over some parts of Straussler’s former works, e.g. the upgraded, duplicated, hydraulic version of the unique Straussler-type wheel-cum suspension from the 1930’s.


Straussler’s vision of an “extremely simple” and “well-sprung” suspension…

The basic idea behind this tank was the mount the strongest available AT gun of the time cooperated with an automatic loading mechanism in the smallest and lightest vehicle possible. With this, it would have been a relatively cheaper alternative for the existing Centurion and Conqueror tanks, which however would still be able to knock out Soviet armor if a conflict broke out.

Additionally – following Straussler’s rather obsolete ideal – it would have been able to travel both on tracks, and if it’s necessary for greater distances, on its wheels as well. To achieve this, the central 4 rollers would have been hydraulically lifted, so the tank could travel onwards without its tracks on its outer 4 driven roadwheels. This would also mean that the MBT would have been able to move even if the tracks were damaged.

With the addition of Straussler’s patented Duplex Drive equipment, the Straussler MBT would also have been amphibious. Whereas this equipment blocked the view for all of the vision ports, the crew could probably only use the common periscope for lookout.6qzfd96

Implementation into World of Tanks

Even though its designation says ‘Main Battle Tank’, if the Straussler MBT would be implemented into the game, it would definitely be a tank destroyer, because another turretless main battle tank, the Strv. 103 is already that on the top of the Swedish TD line.

Also, some could argue that this is a British tank; therefore it should be placed in the British tree in the game as well. This is absolutely correct. The Straussler MBT was designed by a British citizen for the British Army.

However, in my opinion the Straussler MBT has an extremely limited chance to become a British tank destroyer in World of Tanks, since there are a number of other, also not that well known but maybe better suited, more interesting British paper designs for the same role. Moreover, the chances to get yet another, third UK TD branch in the foreseeable future are next to minimal.

Therefore I suggest this tank to be the tier 10 candidate of the (otherwise impossible) Hungarian tech tree, which would possibly look like this:sxrnz3y

The reason for this is because:

a)   The Straussler MBT had a very loose connection to it through its creator, who was born in Hungary, and maintained close connections to his fatherland throughout his whole life. He would also be represented in the Hungarian branch anyway, with the bottom tier V-3 and/or V-4 light tanks.

b)   The number of remaining tech tree content for WoT is extremely limited, especially the full, tier 1-10 lines. With the Straussler MBT on top, the Hungarian tech tree would become a “new” viable option for the future. Without it, the Hungarian tanks will probably never make it into the game, or maybe only as premium tanks.

c)   The theoretical Hungarian tree desperately needs top tier vehicles. The pre-war and WWII content for the Hungarian tree is suitable to make a full light-medium tank line and a partial tank destroyer line from tier 1 up to tier 7. But Hungary has nothing to offer for the top 8-9-10 tiers other than a yet another T-54/T-55 clone, which would still be the same as the one in WoT already anyway. With the addition of the Straussler MBT, the Hungarian tree still lacks a proper tier 8 and 9 candidate, but least it would have an interesting vehicle on top.

d) It would made the possibility of implementation more likely, which might open an opportunity for further research in this topic.

In World of Tanks

Let’s see how the abovementioned raw data would translate into WoT.

Dimensions: The Straussler MBT would have been a rather small vehicle. To put those numbers in a perspective, it roughly had the same height as the AMX ELC bis, but the MBT would have been much wider and longer than that. The closest thing for it in game is probably the size of the hull of the Bat.-Châtillon 25 t (without its turret).rqzvjatzvq0jnkThe size of the Straussler MBT compared to the 170 cm (5,6 ft) tall Mr. Pink.

Firepower: The Straussler MBT’s main armament is quite similar to the 120mm guns on the British tier 9 and 10 heavy tanks, the Conqueror and the FV215b or on the tier 9 turreted TD, the FV4004 Conway. In the game, the MBT would basically get that 120mm gun with a 3 round autoloader, because the tanks in WoT usually get the halved magazine sizes of their real life counterparts. It would certainly make this rapid, small and probably very stealthy vehicle a serious threat in WoT.

The additional ATGM can be neglected, as it was just an optional supplement.

Mobility: With those stats, this tank would be as mobile as a light tank.

Protection: Unfortunately, Straussler did not bother to write anything about the protection values of his creation in its description… But considering the low weight of the project, in my opinion its armor probably would be as thin as on a light tank.


Conclusion: In WoT the Straussler MBT would be a very small, stealthy, and rather nimble tier 10 tank destroyer, which could still deliver quite a punch with its 120mm, three shot autoloader, which means decent penetration and 1200 average damage per magazine with the current values. However, to balance this, it probably offers little to no protection against incoming enemy fire.

    1. nvm, just noticed Mizutayio posted it 🙂
      Very interesting article, though. I guess eventually, WG will have to dip into Hungarian vehicles, there’s not too many left of the others.

  1. MemeMachine says:

    Ok now we are getting ridicolus
    Whats next tibet line?
    There is more possibility of a hungarian tree than an italian one now?
    Wow whats next secret nuke lounching russian paper tanks?
    Your next line is
    “Im not saying it should come out sooner than the italian one also i dont control what wg decides im just proposing a line”

  2. It's_me says:

    Considering how many fantasy tanks (and fantasy versions of fantasy tanks) are already in the game, I don’t see why the Hungarian tech tree would be a problem to implement because of two missing tiers… And this Straussler MBT looks cool at least, it reminds me of the E25.

  3. SpeedyCraft51 says:

    That sounds like a tier X E-25. Would be interesting.

    Also I think the amphibious things are also used on Strv103 IRL ?

      1. “We must go deeper” if its happens you have a chance to get into the Bovington Tank Museum again , go deeper, Straussler had lots of “mad” idea i bet there is more tank blueprints than this one

  4. OrigamiChik3n says:

    Yes, please. More paper tanks (if ANY actual document regarding this tank exists) with autoloaders is the one and only thing we really need in WoT.

      1. OrigamiChik3n says:

        On the other hand, “introducing WT auf E100, denying it’s imbalanced, admitting it’s imbalanced, incompetently trying to balance it several times, removing it from the game. Rinse and repeat” is also what people doing it do. Do we really need to encourage them?

  5. No_Quarter says:

    Article is great but problem with the tank is that it is just another E25 meaning it’s kinda cancer.
    With 3-shell clip it is like Skoda T50 fucked E25 – that’s two op tanks in one….
    I just feel it would be really bad for the game, you cannot balance fast small tank with good gun

      1. No_Quarter says:

        still insane camo does not make gun depression a problem as tank of this size cannot be spotted easily, and 120mm is not loudest gun so even when firing it is not that bad.
        And we already have hp/t here which is insane in terms of balance, I just doubt we need E25 on T10

      2. 6 degrees of gun depression is the same on an obj 140 and any pro can tell you that they can make terrain work for the extra depression. If you want to be able to tag a tank with zero gun depression then you should start by giving it 3 degrees of Chinese medium gun depression but right now it is too average to be a downside.

        Otherwise, No_Quarter has a point that it is terribly similar to an E25 and essentially, the current Strv-103 B fills the role of an E25 at tier X anyways. This hungarian tank would essentially be a more mobile Strv-103 B but with an autoloader as well as better reaction time because the gun can traverse. The two would have very similar armor (small tank, little space for armor), same size, same alpha. You would have to give this tank significantly awful gun handling, terrain resistances, a slow interclip round (ie 3-4 sec), limited view range, and practically zero camo on firing to help balance it out.

        Personally, if you wanted to balance this tank out, throw the autoloader out of the window right now because tiny autoloaders make balance an absolute nightmare. You’ll have to wait for overmatch mechanics to be implemented so the Strv 103B becomes more differential from this hungarian tank while also looking to give this tank hydro pneumatic suspension or siege mode. Not focusing on tilting the tank but outright raising and lowering the hull to make it a unique addition to wot.

        TL;DR: Tank needs 3 degrees of gun depression, no autoloader (if not, god awful soft stats), and should have a siege mode for raising the hull on the flat, no tilting.

  6. Interesting concept, but it’s pretty clear why this never left the drawing board.

    The mechanical complexity of a tracked-trackless design and the need to basically make it out of aluminium to reduce the ground pressure of the vehicle and meet its speed targets.

    Ultimately, I’m not sure how they could balance a vehicle like this in the game. My fear is that it would essentially become a Tier X autoloading E-25, which doesn’t sound like a particularly great idea. Unless they rework how concealment works in the game entirely.

  7. ndiver says:

    Enthralling article 🙂 I loved the deeply detailed history and the reconstruction of this potential tank. I hope to read other articles like in the future !

  8. wolvenworks says:

    i think it may fit into AW lowtiers, if they decided to do paper design tanks too (which they’re currently not doing. they’re limiting the tanks to those that are actually made)

  9. Tommy_Gun says:

    Judging from the look of this tank it is probably going to be a TD. An overgrown E-25 on steroids…
    (btw. didn’t WoT developers said once that they will increase role of armor and decrease camping ? Right now we have a new armor-less dedicated to camping Swedish TD line. Just saying… )

  10. Karika, simply wonderful article, you are an outstanding researcher and it made this very fun to read. That much said is the truth. I do think you shot yourself in the foot by trying to sell your tank as a tiny autoloading E25 at tier X. If you do make a future article, I would fully recommend doing a stat compare with other tanks of similar caliber even outside of the same tier and class (ie. show a stat compare with an E25, Strv-103B, Skoda T50, TVP 50/51, or BC-25t). Even a simple excel sheet would help presentation. Your current article is better than not giving any kind of idea of how this tank could be implemented into world of tanks, definitely, but the possible implementation of an overpowered tank is pretty much what got everyone up in arms about and it would help significantly if you could dispel that stigma.

  11. Rombat says:

    wow so many people are fooled by so called historians who go deep in unknown archives of their brains to onvent some fantasy vehicles in order to get some money from wg for their nightwetdreams…

  12. Dan BT says:

    Very nice article. For sure they will implement in the future. On the other hand, for Romanian tanks there is no hope, we also had our tank concepts, like the Maresal, which was modified and implemented by the germans as the “Hetzer”…

    1. I’m not sure if you’re still active, but there are lot of currently undiscovered Romanian tanks.

      One was recently discovered by one my friends and it was referred to as the Tun Antitanc Autopropulsat.

      I’m sure you’re interested 🙂

  13. Hi Karika – I am an Alvis historian and researcher and have a number of prewar photos of Alvis/Straussler tanks manufactured in the Alvis factory in UK. Are you interested? If so we could correspond and exchange pics and info.

    Hello Mr. Németh,

    My name is Eduardo and I want to ask you about a matter.
    I like writing and now I am writing a book about Hungarian armored forces in World War II in Spanish language. I think that the graphic section in the book have to be a milestone that could increase the quality of the text. So I am interested in pictures or photographs of tanks, armored vehicles or similar.
    So, please let me know if is possible that you send me files (pictures or what you consider) about the matter.
    Of course if you send me them and I use them in the text, I´ll write the source in the credits.
    Waiting for your news.

  15. everyone here is comparing it to the E-25 being in Tier X…but what you all Forget is the E-25 is the last tank in the game that DID NOT lose cammo co-efficient while firing. if this tank has normal cammo loss while firing then it will be a decent Addition to the game and not the OP game breaker that the E-25 is. that in itself is enough to Balance out the Clip if it had 3 sec betweeen shots..6 secs to get shot at
