T26E1-1 is the false designation for the T26 ingame

[Krapfen]

Here you go;

The T26E1-1 denomination is probably the most common mislabel. It comes from the fact that the earliest images of the first prototype show it having “T26E1-1” written on the side of the turret. The vehicle was, indeed, the first T26E1 prototype, which is where the writing on the turret originated. The writing was not modified when the vehicle received the new gun. T26E1-1 is not the designation of a new type of vehicle, but how the first T26E1 prototype was labeled. Below, the T26E1-1 vehicle can be seen before receiving the T15E1 gun.

Another development was to convert normal M26 Pershings to mounting the T54 cannon, another development of the T15E1 which featured shorter ammunition. These tanks were redesignated the M26E1, but work was halted due to issues with the guns and a cut in project funds.

In an effort to match the firepower of the Tiger II's more powerful 88 mm KwK43, the T15E1 90 mm gun was developed and mounted in a T26E1 in January 1945. This tank was designated T26E1-1. The T15E1 gun was 73 calibers in length and had a much longer high capacity chamber. This gave it a muzzle velocity of 3,750 ft/s (1,140 m/s) with the T30E16 APCR shot and could penetrate the Panther's frontal armor at up to 2,600 yd (2,400 m). This model used a single piece 50 in (1,300 mm) long ammunition and was the only Super Pershing sent to Europe.
A second pilot tank was converted from a T26E3 and used a modified T15E2 gun that used a two piece ammunition. A total of 25 of these tanks were built and designated as the T26E4. An improved mounting removed the need for stabilizer springs. Since M26 was designed to fight the heaviest German armour, weak mantlet proved to be a big problem. It wasn’t able to stop the shells from 88 mm KwK 36 used on the Tiger I, not to mention 88 mm KwK43 from the Tiger II. The designers chose crude, but effective method. They welded additional 80 mm armor plate in front of the mantlet to increase its resilience. Original plate that was welded was salvaged from the destroyed Panther tank.

*I am not at all discrediting this information*
this is just a warning for the future.

I personally have found out, I would be careful siting Tanks-Encyclopedia. I actually found plenty of errors with some of it’s tanks, it’s not a reliable resource. A lot of it’s information comes from Wikipedia as well.

the tank ingame appears to be the original prototype. Because the other T26E4 didnt have the addon armor?

One could be guided by that but, according to what I searched, what gives away the difference between the T26E1 w/ Add-on armour (Super Pershing) from the T26E4 is the gun, the T26E1 uses the T15E1 gun while the T26E4 uses the T15E2 gun, the difference between both gun is that the first uses a one piece ammunition while the second one uses a 2 piece ammunition, you can see the ammunition difference in-game if you compare the ammo the T26E1-1 uses vs the ammo the T32 and T32E1 use...

Edit: The T26E4 did have the add-on armour, according to WoT Wiki, this[wiki.gcdn.co] is a T26E4 with the add-on

As far as I am aware, their source of reference in the Super-Pershing article linked above is the same as the one used by the War Thunder wiki... As for the WoT Wiki, despite WoT being hugely innacurate, I have found they have quite a good historical matterial in their wiki...

I really dont know what you are trying to say with this but please, continue.

What I find weird is that on the WT wiki it says the T26E1 and the T32 M26E1 all use the same 90mm gun, but clearly they dont (?) Im also interested in, what the advantage was having a two ammo instead a one piece, I mean sure it was easier to move around in that cramped turret, I mean look at the size of the shell in game on the T26E1 and then the distance between the breech and the radio

[torindechoza]

i saw pictures of T26E4 without addon armor.

That the designation T26E4 is also wrong... The Designation should be T26E1

Same Caliber, but different guns, the M26 uses your average 90mm, the M26E1 uses that average 90mm with a slightly modified breach allowing it to fire bigger rounds with more propellant... The T26E1-1 uses a bigger 90mm that allows it to fire a bigger round (propellant wise, it is the same as the M26E1), the T32 uses that same big 90mm but modified so it could fire 2 pieces ammunition, that way the loader has to put the warhead and then the propellant.

Generally, 2 piece ammunition is often used when the tank interior is too cramped to allow the Loader to carry the big shell, for instance, the IS-2 uses 2 pieces ammunition compared to the T-44-122. On the other hand thou, if the loader has enough space to move the whole ammo in 1 piece, it will reload faster.

[Katokevin]

Going off some memory here, but IIRC, the version we have is the inital version to mount a long 90mm. For the vehicle, I believe they used one of the T26E1 (of which around 10 or so were built) as a test bed for the T15E1. With that, the original T26E1 designation was kept, but -1 added to the end to denote the use of the T15E1. After that, the T15E2 was selected for testing which would be noted as the T26E4. In theory, the T26E1-1 does fall into the T26E4 designation as it was a 4th test bed of the T26 series, but since an E1 test bed was used, it became T26E1-1.

A mistake on the wiki. The single piece ammunition was just to much for the loader to work with in such a confined space (similar to the T-44-122), so it was decided to switch to a 2 piece system while at the same time shortening, but widening the propellent case to get the same velocity out of a shorter charge.
