Military tanks are an impressive sight that makes enemy infantry shake in fear, but sometimes that isn’t enough. Sometimes you need to make the enemy flee in terror. That’s where the super heavy tanks come in.

Super heavy tanks is the classification for the heaviest and biggest military tanks. Almost all of the super heavy tanks were constructed by mad engineers around the time of WWII. Especially the Nazi engineers where more crazy than most – or maybe they were just allowed more freedom in a desperate attempt to turn the tide of the war.

Here are the top 10 heaviest and biggest military tanks ever.

Landkreuzer P. 1500 Monster

In 1942 Hitler approved the design and construction of an extremely large tank, but the project was cancelled in 1943 before any actual construction had begun. The tank was supposed to be more than fifteen times as big as a normal tank and it should have been armed with a 800 mm Krupp cannon (the main cannon on a normal tank like the M1 Abrams is 105 mm).

The 800 mm Krupp cannon is the largest artillery weapon ever built. Each projectile weighted 7 tons and it could be fired up to 37 km (23 miles). I haven’t seen any pictures of the Landkreuzer P. 1500 Monster, so you must make do with a picture of the Krupp cannon (check out the soldier in front of the cannon).

Landkreuzer P. 1000 Ratte

The Ratte was very similar to the Monster. It was also designed in 1942 and it was also cancelled within little more than a year. Unlike the Monster, the Ratte were supposed to be armed with a warship turret with two 280 mm cannons. Other armaments on the Ratte would have included a 128 mm cannon, eight 20 mm anti-aircraft guns and a few 15 mm machine guns.

Some German guy have built a model of the Landkreuzer P. 1000 Ratte. His last picture of the model really gives you an idea about the size of this thing.

Panzer VIII Maus

The Panzer VIII Maus is the biggest tank ever built. It was small compared with the Monster and the Ratte, but still three times bigger than a normal tank. The design was complete in 1942 and production started in 1942, but only two were completed before the war ended.

The completed tanks were armed with a 128 mm primary cannon and a 75 mm secondary cannon.

Panzer VII Maus

Germany, 1944 – 10 meters long, weight 188 ton, crew 6

E-100 Tiger-Maus

A super heavy tank very similar to the Panzer VIII Maus. This project was also started in 1942, but no models were ever completed. A single hull was built in 1944, but no turret was fitted before the war ended.

The E-100 Tiger Maus was supposed to use the same turret as the Panzer VIII Maus. Thanks to a lighter weight, it would have been faster and more practical on the battlefield than the Panzer VIII Maus.

FCM F1

The FCM F1 is the heaviest and biggest tank not of Nazi origin. It was supposed to replace the Char 2C, which is one of the heaviest tanks to ever see combat. Unfortunately France was defeated before the FCM F1 project was completed, so none of these tanks were ever built.

The FCM F1 was supposed to have a 90 mm cannon, a 47 mm cannon and six machine guns. It is worth noticing that this tank was more than 10 meters long, but still only a little bit more than 3 meters wide so it could be transported by train.

France, 1940 – 11 meters long, weight 139 ton, crew 9

O-I

The O-I was a Japanese attempt at building a super heavy tank. It has been reported that one model was completed and sent to Manchuria during WWII, but it is highly unlikely that the rumor is true. The O-I probably ended up as a cancelled project in much the same way as most of the other super heavy tank projects.

The O-I had three turrets. The main turret had a 105 mm cannon, one of the minor turrets had a 37 mm cannon and the other minor turret had three machine guns.

K-Wagen

The K-Wagen was one of the first attempts at building a super heavy tank. Again it was the mad engineers of Germany that did the attempt, but for once it was before the Nazi era.

The K-Wagen didn’t have a main turret. Instead it had four 77 mm fortress guns mounted on the sides and seven machine guns. It is the second largest tank ever built – only the Panzer VII Maus is bigger since all the other super heavy tank projects were cancelled before they could be completed.

T-28 (Gun Motor Carriage T95)

The T-28 was designed by US Military during WWII. It was supposed to be used to break through German defenses and an eventual invasion of Japan.

The T-28 didn’t have a normal turret, so one might classify it as a tank destroyer and not a super heavy tank. This is probably the reason it was renamed from T-28 to Gun Motor Carriage T95 and later back again.

It was armed with 105 mm cannon and a single machine gun. It was so heavy that it had to use four tracks instead of the normal two.

TOG2

The TOG2 was the largest British tank ever built. Just like most of the other super heavy tanks, it was designed during WWII. A single prototype was completed in 1941, but no further development occurred and no TOG2 ever saw combat.

The TOG2 was armed with a 76 mm main cannon.

A39 Tortoise

Another British super heavy tank. The problem with this one was that the first prototype weren’t completed before 1946, by which time the interest in super heavy tank development had disappeared.

The A39 Tortoise was armed with a 96 mm cannon and three machine guns.

How Big Were They Really?

Check out this diagram, that I have glued together:

The Biggest Tanks

Be aware that the two biggest tanks (Landkreuzer P. 1500 Monster and Landkreuzer P. 1000 Ratte) never made it past the design phase, so they might have ended up looking very different from above. I just glued their pictures together from pictures of other tanks, so you could get an idea about how enormous they were.

Why Did They Disappear?

It is interesting that almost all the tanks in the top 10 were built during WWII. What made the engineers at that time try to build such monsters and why have no such tanks been built ever since?

The main reason for building the super heavy tanks was immunity from enemy fire. A super heavy tank would have featured thick armor that would be impenetrable to most WWII weapons. Being able to move around on the battlefield without fearing enemy fire would have been quite an advantage, but unfortunately it wasn’t possible to be immune from everything.

Enemy aircraft would surely target a super heavy tank on the battlefield, since it would be a big and easy target. Escape would be impossible for most super heavy tanks, since they would to slow to move away from the enemy fire.

Today, enemy fire is much more powerful than during WWII. It is easy to imagine how rockets or missiles could destroy a super heavy tank much easier than a group of smaller tanks.

The lack of defenses against air strikes weren’t the only problem with the super heavy tanks. The construction of such a monster would require enormous amounts of raw materials – something that was in short supply during WWII and probably used better elsewhere.

Another problem would be the transportation of a super heavy tank. Most of them were too big to be transported by train, so they would have to rely on their own ability to move forward. Problem was that most of them were extremely slow, so they might not reach the battlefield before it was too late.

In addition, the super heavy tanks were often so heavy that they would destroy normal roads. They would therefore have to drive through fields and so on, which meant even slower movement than were possible on normal roads.

Why didn’t the engineers make the Landkreuzers able to use both railroads and normal roads?

Use the railroads for getting close to the action and then normal roads for last few kilometers. Low speed wouldn’t have been such a big problem then.

2

how about a follow-up article on the biggest tanks that were actually used?

3

Excellent idea adam. I’ll look into that soon.

4

The problem with being able to use railroads is width. It’s difficult to build a super-heavy design with enough width to fit everything that needs to be wide – like the turret, to fit the big gun – and to fit the engine in the hull – and yet also make it fit the 11 foot (~ 3.5m) width that a rail car can carry. Fitting through railway tunnels is important if you’re going to be moving big stuff by rail.

Length is also an issue, but much less of one, until you get to the size of something like the P.1500.

>> “What made the engineers at that time try to build such monsters?”

They expected that the evolution of battleships (i.e. ever larger vessels with more armour and bigger guns) would be repeated on land. This expectation dates to the invention of the internal combustion engine, as you can read in this prediction from 1900:

“Huge forts on wheels will dash across open spaces at the speed of express trains of to-day. They will make what are now known as cavalry charges.”

In fact the first British tanks in WW1 were referred to as “land ships”.

>> “why have no such tanks been built ever since?”

[1] Ships can displace a 3-dimensional volume to support their mass, but the area of land occupied by a tank is only 2-dimensional. Thus, all other things being equal, as you enlarge a tank its ground pressure will increase. It will therefore become more likely to get bogged down in soft ground.

[2] Rough ground poses problems for all sizes of tank, so road and rail networks are very attractive to tankers. These networks impose size and weight limits.

Please scroll down to the photo third from the last. There are no photos of this weird monster but two of them built.

http://www.englishrussia.com/?p=977

Supposedly, one of them snapped in half crossing a ravine, and the other was damaged when the rear turret was accidentally discharged into the center turret (no lockout, I suppose).

Does anyone have any more information on this WWII Weirdo?

The Abrams main gun is 120mm…

9

original design & 1st generation m1 were 105mm

120 gun came with a1 version mid 80s (i believe some usmc tanks were still using 105 in gulf 1)

10

that was very informative i thought, tanks rock :)

11

The reasons that they were not persued in Europe were that 1) the infrastructure couldn’t support them. Areas were too built up, roads were narrow, even the autobahn had limits on bridges both in weight and width. 2) as fuel became harder to obtain, it became logistically impossible to sustain. And 3) as was shown in the Ostfront, when the spring came, everything turned to mud. these monsters would just sink in and become a permanent fixture.

12

Here’s a concept picture of the p.1500 “Monster” from wikipedia. Seems to fit with other concept art I’ve seen of it, but this is one opf the best reditions, shown to scale with with I think is a “Maus”, and a truck.

which railroad could stand 1500 tons .
the heaviest locomotive in history was 450 tons . that tank would smash the railroads in seconds .

14

i wish to buy tanks
any make or aircraft and they dont have to be able to drive fly

Today, doctrine drives the characteristics of tank development. After WWI, Germany was best positioned to develop an armored force doctrine which emphasized speed, penetration and exploitation – perfect role for the tank. As they explored what characteristic the ideal tank should have they learned that bigger was better until they went through the ceiling and over did it. Well-armored and armed mediums became the most successful in a broad application of tasks but they had to explore the limits. The big tanks failed and went away because they were too specialized.

Jonathan, shown to scale is a king tiger and a truck. I don’t think that obtaining the amount of raw materials would be as difficult as the complexity of the design, besides the biggest problem the nazis had was the way they designed tanks, they were meant to look good on paper, that is why they started the war whit tanks that were no better than those of the allies (they believed their tanks were better). It is ironical that hitler brought germany back in power and it is he who drove it into the abys, in this matter he was no better than mussolini, he was presented something on paper and then decided what to make, the problem is he probably never saw a tank in action and he certainly wasn’t a technician. The nazis would probably be much better of if they used their resources to make something that worked, rather than wasting them on such stupid designs, perhaps if the SS would be in charge of their tank construction all along they just might have got the SCHWARZWOLF ready for production.

17

Why the not use railroad and what the heavy tank used at battlefield right now

18

The U.S.Mlitary should build scorpion tanks like in HALO. It would make a great replacement for the M1A1 Abrams in the future.

well it was long to read but really good and intresting, as i am totally intrested in tanks
they were just great
