Do not fill this in!== Variants == STT-89 has 3 main variants that don't differ too much. The first two only saw two battles. * STT-89C, the first and main prototype. The 'C' stands for 'Cannon' since it's fitted with a 120mm Cannon. * STT-89SB, the second prototype. 'SB' stands for 'SmoothBore' since it's fitted with a 140mm SmoothBore Cannon. It has an unmanned turret, with the gunner sitting behind the driver. It can fire HEATFS ammo able to penetrate 210mm of armor, or APFSDS ammo able to penetrate up to 580mm of armor with 1545m/s muzzle velocity. The turret also has two 14.5mm coaxial machineguns. * STT-89SPG, the Self-Propelled Gun prototype. It's fitted with a 203mm Howitzer that can fire powerful HE ammo. The Turret does not have a mantlet, due to the works on the STT-89 tanks being halted when the SPG was being built.
