The D-8 Armored vehicle, designed in 1931 by N. I. Dyrenkov, was relatively light and had no turret. The design utilized a licensed passenger car Ford A chassis. Two machine guns were used on hull's sides, not providing a 360-degree coverage. The D-8 had a two-man crew sitting back to back so that the rear man could fire a rear-mounted machine gun. In 1932, the D-8 was upgraded with small turrets and had the DT machine gun mounted in it in order to reduce the vehicle's vulnerability. The D-8 was quickly phased out of production in lieu of the heavier and better equipped FAI armoured car.
