Comparing: Challenger vs. E 25

Created in 1942 based on the extended chassis of the Cromwell. One definite advantage of the new vehicle was its 17-pounder gun, which was the most powerful British gun at that time. This allowed the tank destroyer to effectively hit the enemy at distances up to 1,000 meters. However, the vehicle had a large silhouette and the chassis was overloaded. A total of about 200 vehicles were built.

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.
