The old Soviet-made SU-100 tank killer still in service with the Vietnamese armed forces 12609152

Of course, SU-100 cannot be used to destroy modern main battle tanks but the ammunition can penetrate armour of light tanks, infantry fighting vehicles and armoured personnel carrier. SU-100 APC-T can penetrate armour of 180mm at maximum of 1,000 m.

The SU-100 was developed from the same chassis as the T-34 main battle tank, but replaced its turret with a casement installation allowing larger guns to be fitted.

Many Warsaw Pact countries also used the SU-100, as did Soviet allies such as Egypt, Angola and Cuba. A few SU-100 were delivered to Yugoslavia after the war, under the designation M-44.

The main armament of the SU-100 consists of one 100mm D-10S which is able to fire AP (Armor-Piercing) and HE -FRAG (High-Explosive / Fragmentation) ammunition. The vehicle carries a total of 33 x100mm projectiles.

The production of the SU-100 was started in 1944, which was essentially an SU-85 fitted with the more powerful 100mm gun M1944 (D-10S), a variant of the gun of the weapon fitted to the Soviet-made T-54/55 main battle tank.

The hull of the SU-100 is all welded with the fighting compartment at the front of the hull and the engine at the rear. The suspension consists on each side of five dual rubber tyred road wheels with the drive sprocket at the rear and the idler at the front. There are no track return rollers.
