Comparing: E 25 vs. SU-152

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.

Development of a tank destroyer on the basis of the KV-1S heavy tank began on January 4, 1943. The vehicle received the designation KV-14 (Object 236). A prototype underwent field trials at the beginning of February 1943 and entered service on February 14, 1943. In April, the KV-14 was renamed SU-152. By December 1943, 670 vehicles were manufactured. Thanks to its ability to successfully combat German Tiger I and Panther tanks, the SU-152 was dubbed "Hunter" by the troops.
