Comparing: E 50 Ausf. M vs. T-22 medium

The German Army demanded that the E-series tanks had transmissions positioned in the rear. However, the E 50 and E 75 tanks used the Tiger II engine-transmission compartment, which made rear placement of the transmission impossible. The E 50 Ausf. M tank was a redesign of the E 50 project with the transmission placed in the rear.

The prototype of the A-22 hull was produced in 1949. The design incorporated rolled armor plates with maximum slope angles. Test firing showed that the hull was well-protected from high-caliber Armor-Piercing shells. The hull was used as a basis for the project of the T-22 medium tank. Development was discontinued after the preparation of the suspension and general design. Later, the best innovations were applied in the development of the Object 907.
