Italys' repsonse to British cruiser tanks. None entered service due to the armistice.
The 1940 design for a heavy tank armed with a 75mm gun. None entered service due to shifting priorities and lack of resources.
A redesigned version of the P43 heavy tank armed with a 42-caliber 90mm gun.
Japans interim solution to superior American tanks by using a Type 1 hull with a down-sized version of the Type 4s turret with a shorter-barreled 75mm gun.
The Type 3 with the Type 4s turret with the same 75mm gun as the Type 4.
The Type 4 Chi-To was Japans attempt at making a tank to counter the superior American tanks being fielded. Has a long-barreled 75mm gun.
Phase 1 of the Chi-Ri using the Type 4s turret.
Phase 2 of the Chi-Ri, using an auto-loading 75mm gun.
The Type 5 Ke-Ho was the latest design of Japanese light tank:
The most modern and capable native tank design of Poland during the war.
The British contemporary of the US T14 heavy tank. Two units were built, one with a 6-pdr gun, and one with a 75mm gun.
The first production variant of the Centurion. Armed with a 17-pdr gun.
Britains first post-war heavy tank design. Armed with a 32-pdr gun.
Heavy tank using the Caernarvon hull, and with a new turret to mount a modified version of the same 120mm gun used on the M103.
The first post-liberation French tank design. Initially armed with a 75mm gun, then redesigned for a 90mm gun. Did not enter service due to using outdated technology.
Somuas competing design to AMX M4/AMX-50 for a heavy tank.
Lorraines design for a 40t medium tank armed with the same 90mm gun as the FCM 50t/AMX M4.
First variant of the AMX-50. Two pilot vehicles were built using differing turrets mounting the same 100mm gun.
The first AMX-50 that used the 120mm gun in an oscillating turret. Was redesigned with heavier armor and a pike-nose. Variant did not see further development due to its tall height.
A redesigned variant of the AMX-50 using a cast lower hull, redesigned front and a lighter turret. To remedy the height issue the hull was redesigned with an angle so the rear was brought lower.
A vehicle designed for taking out forifications of the Maginot line. Two vehicles armed with a 10,5cm gun was built. Both saw service on the Eastern front as tank destroyers where both were ultimately lost.
A war-time design for a heavy tank using a 76mm gun and HVSS suspension. M6 variant used a cast hull.
Same tank, but wielded hull.
The M6A2E1 was to serve as the testbed for the 105mm gun to be used on the T29. As such, a larger turret was made and extra armor was added frontally.
Designed as a light tank to replace the M3/M5 Stuart, it ultimately grew in size and weight comparable to a medium tank. Was cancelled in favour of the M24 Chaffee.
The T20 program was an attempt at replacing the M4 Sherman with a lower profile vehicle with superior protection and firepower. Multiple versions were made that tested out different suspsensions and guns from a 75mm gun to 90mm guns.

T21 light tank
T22E1
T23
T23E3
With the cancellation of the T20 program, a new program was developed for a larger medium tank with thicker armor and a bigger gun. The program was utlimately cancelled in favour of the even heavier T26 program using the same turret and 90mm gun.
The T26E4 was the pilot program for the Super Pershing, which has a 73-caliber version of the 90mm gun. It had a spring stabilizer outside above the gun to help stabilize it as a stop-gap solution. When it arrived in Europe some extra armor plates from a Panther were added to the front and sides of the turret for added protection (the wings on the side were for counter-balance.)
Here's the actual production model of the Pershing, the M26.
The T29 was an attempt at making a tank comparable to the Tiger II. Having a very well armored turret that was large enough to mount the same 105mm gun used on the T28/T95.
The T30 was a T29 modified to mount a 155mm gun.
The T34 was converted from one T29 and one T30 to mount the M1 120mm AA gun. Tests of the T34 would lead to the M103.
The T32 was essentially an enlarged Pershing with heavier armor and a larger turret to mount the same 105mm gun as the T28 and T29.
The T54 used the M48 hull with a conventional turret mounting an auto-loading 105mm gun.
The T54E1 used the M48 hull with an oscillating turret mounting an auto-loading 105mm gun.
The T54E2 used the M48 hull with an conventional turret mounting a non auto-loading 105mm gun.
The T57 used the T43/M103 hull with a large oscillating turret mounting a 120mm gun.
The T69 used the T42 hull with an oscillating turret mounting a 90mm gun.
The T42 was a development intended to replace the M26 and M46 medium tanks with a completely new design. The tank scare during the Korean war ended the program as it was quicker to simply add the T42s turret onto the M46 hull, creating the M47 Patton.
The T-43 was a program to replace the T-34 and fixing some of the issues with said design. Was ultimately cancelled in favour of making T-34s with the 85mm gun.
The T-44 was another attempt at replacing the T-34, using a smaller and lighter tank. Armed with a 85mm gun.
A lengthened variant of the T-44 using a 100mm gun.
Same variant, but with a 122mm gun.
