Comparing: SU-100M1 vs. E 25

Developed at the UHMP (Ural Heavy Machinery Plant) on the basis of the T-34-85. The fighting compartment was located in the rear. The vehicle superceded by the SU-100M-2, based on the basis of the T-44, and never manufactured.

Development of the E 25 was a part of the "E" program, aimed at unifying the manufacture of the German armored forces. The program was supervised by the Waffenprüfamt 6 committee, directed by General Kniepkamp. The E 25 was developed by the Argus company (Karlsruhe, Germany). No prototypes were manufactured, the vehicle never underwent trials or saw service. However, according to some sources, by January 23, 1945, several hulls were produced and remained in Katowice waiting for trials.
