1/100 SU-86 Siege Tank

One of my own designs, the monstrous SU-86 siege tank or self-propelled gun. This is based on my T-86 chassis, except that the hull is slightly deeper to make room for the relocated engine and large magazine. The SU-86 is armed with a 300 mm main gun, the type found on rail cars during World War I. Such massive weaponry merits a very heavy platform to support it; according to my calculations, the SU-86 would weigh around 120 tonnes (which is heavier than any WWI tank but still lighter than the German Maus). The SU-86 could conceivably be used as a tank destroyer, but is far more useful for bombarding enemy cities and military bases with explosive and incendiary shells.
