The IS-7 heavy tank design began in Leningrad in 1945 by Nikolai Fedorovich Shashmurin [1] [2] [5] Weighing 68 tonnes, thickly armoured and armed with a 130mm S-70 long-barrelled gun, it was the largest and heaviest member of the IS family [4] and one of the most advanced heavy tank designs.

The Obiekt 279, or Object 279, (Объект 279) was a Soviet experimental heavy tank developed at the end of 1959. This special purpose tank was intended to fight on cross country terrain, inaccessible to conventional tanks, acting as a heavy breakthrough tank. It was planned as a tank of the Supreme Command Reserve. [citation needed]
The Obiekt 490 "Poplar", or Object 490, was an experimental Soviet tank developed in the early 1980s. [1] Two versions of the vehicle existed under the same project name, however the designs were radically different, with the second being one of the most unusual designs in the history of tank development.

The AAI High Survivability Test Vehicle (Lightweight) arrives at the U.S. Army Armor & Cavalry Collection at Fort Benning, now Fort Moore, in 2021. In early 1977 the Army selected proposals from AAI and Pacific Car and Foundry for HSTV(L) concept feasibility analysis.
The MBT-70 (German: KPz 70 or KpfPz 70) was an American–West German joint project to develop a new main battle tank during the 1960s.. The MBT-70 was developed by the United States and West Germany in the context of the Cold War, intended to counter the new generation of tanks developed by the Soviet Union for the Warsaw Pact.
In the late 1920s, the Polish Armed Forces identified a need for a new tank design. The Wojskowy Instytut Badań Inżynierii (WIBI), or "Military Engineering Research Institute", dispatched Captain Ruciński to the United States to legally acquire a Christie M1928 tank, along with its blueprints and a licence for production.
The only extant design blueprint, [5] W 1661, dated 9 April 1942, shows a 90-ton tank armed with the 105 mm L/70 gun, the originally-proposed armour requirements (120 mm front, 100 mm sides), and the 800 hp HL230, with a top speed of 23 km/h (14 mph).
It was to have been based on the hull and turret design of the T20 but with a maximum armor thickness of 30 mm (1.2 in) it would weigh only 24 short tons (22 t) been armed with the 76 mm gun, used either a torsion bar or use the vertical volute spring suspension of the M7 Medium Tank (originally known as T7 Light Tank).
