About this vehicle
Blueprints for the NST (noviy sredniy tank or new medium tank) were completed in 1966. One distinctive feature of the vehicle was its four-loop chassis with a drive for each loop. The transmission allowed the amount of power transferred to each track loop to be regulated. The project remained in blueprints.
