The SU-100Y was a 130mm self-propelled gun of the Soviet Red Army . It was equipped with a ship's gun and was therefore also called a marine self-propelled gun.

development

The SU-100Y should be used as a self-propelled gun to fight heavy bunkers . It was created on the hull of the only heavy tank prototype T-100 , which was tested under field conditions in the Finnish-Russian winter war of 1939/1940 and did not prove itself because the armament consisting of a 76.2 and a 45 mm cannon was Finnish Couldn't destroy bunker. First, a larger 152mm cannon was to be installed on the T-100. This model was designated as the T-100-Y, but was soon discontinued because of the KW-1 and KW-2 with its superior 152mm howitzer.

On January 8, 1940, new plans for the successor, the T-100-X, were completed and sent to the Ischorawerke (Factory No. 185). The T-100-X had a box-shaped structure and was equipped with a 130 mm ship cannon. A torsion bar suspension was installed for mobility. In the further development of the prototype, the shape of the structure was modified in order to reduce the ammunition loading time. The new design became known as the SU-100Y (sometimes called the SU-100-Y). The drafts of the SU-100Y were sent to the Ischora factory on February 24, 1940. The only prototype was completed in March 1940. By the time the prototype was completed, the winter war had already ended, which meant that the SU-100Y could no longer be tested under combat conditions and series production was never possible.

construction

The SU-100Y was created by converting the hull of the only prototype of the T-100. The GAM34 torpedo boat engine, a variant of the Mikulin AM-34 aircraft engine, served as drive .

The SU-100Y was equipped with a 130 mm B-13 ship gun in a non-rotating and particularly striking closed box-shaped structure.

commitment

The only SU-100Y was used in the winter of 1941 at the height of the Battle of Moscow, with no record of the exact use and possible successes. The SU-100Y survived the war and is now on display in the Kubinka Tank Museum.
