Object 227/U-13

The KV-7 was an experimental self-propelled gun built on a KV-1 hull in 1941, with two 45mm cannons flanking a central 76,2mm cannon in a fixed casemate. Its performance was unsatisfactory, leading to the development of the KV-7-2, also known as U-14, which replaced the two 45mm cannons with a second 76,2mm cannon. Its performance was also unsatisfactory, so the designers shrugged their shoulders and put the biggest gun they could think of in the next prototype, which ultimately led to the development of the SU-152.

Models available:

U-13 (KV-7)
