Comparing: T-22 medium vs. Centurion Action X

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.

The Action X turret was planned to be used for later variants of the Centurion tank. One prototype of the turret was mounted on the chassis of the Centurion Mark 7, and another was used for ballistic trials. The vehicles with the Action X turret never entered mass production or saw service.
