There existed two different JS-6s: the Object 253 was an attempt to develop a practical
electrical transmission system for heavy tanks. Similar systems had been tested
previously in France and the United States and had been used with limited success in the
German Elefant/Ferdinand tank destroyer during World War II. The experimental
transmission proved unreliable and was dangerously prone to overheating, and
development was discontinued. The alternative Object 252 shared the same hull and
turret as the Object 253, but used a different suspension with no return rollers, and a
conventional mechanical transmission. The design was deemed to offer no significant
advantages over the JS-2, just the reload time was less, and the JS-6 project was halted.

Since the JS-6 proved to have no significant advantages over JS-2 and its rival JS-4, in
November 1944, they decided to dramatically upgrade the tank. The project was called
"Object 252U" (U stands for "Improvement" in Russian). The tank featured a heavily
sloped pike-nose armor, a new 122mm D-13T gun, and more slope on the sides and rear.
The design proved to be problematic in terms of crew comfort since the interior was too
cramped and the design was cancelled.
