Comparing: Bat.-Châtillon 155 55 vs. 212A

A 155-mm SPG design project developed in 1955. The vehicle was intended to be manufactured on the chassis of the U.S. M47 medium tank, which was exported to France. However, the chassis of the French medium tank Batignolles-Châtillon 25 t was preferred over other variants. The initial version existed only in blueprints.

Technical requirements for the 212A self-propelled gun were developed in August 1940. The Special Design Bureau No. 2 of the Leningrad Kirov Plant started development based on the KV-220. Blueprints for the vehicle were ready by February 24, 1941, but a prototype was never manufactured. By August of 1941, development was passed on to the UHMP (Ural Heavy Machinery Plant), but a prototype was never built.
