High command
The official request for the new tank from the High command was however given only in 1949 (all the previous army involvement was on an unofficial level). The Škoda project received thus an official designation - T-50, the ČKD project received the T-51 designation, but by 1950, both projects were unified under the designation of T-50/51. Forced by the Soviet Union and pressed into accepting the Soviet tanks into their army, the Czechoslovak High Command had to abandon the support of the project. Few months later, all the independent design and construction works in Czechoslovakia were ended and that marked the end of the last truly independent Czechoslovak tank project.
