Comparing: Object 907 vs. T-22 medium

The decision to start development of a next-generation medium tank was made on July 13th, 1953. Development was carried out by Research Institute No. 100. The project was submitted in March 1954, and at the beginning of 1955 the hull of the new vehicle was tested for shell resistance. However, later the project was canceled.

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.
