Historical Reference:
In the early 1950s, the US military sanctioned a range of research and development work on next-generation tanks. The result was a series of Questionmark conferences, at one of which the TS-6 tank project was proposed in June 1954.
The key idea was to create a lighter vehicle with similar performance characteristics compared to the Heavy Tank T43 (M103) and T110. Work stopped at the documentation stage.
