KV-2 heavy tank. On the eve of World War II, the Soviet Northwest Command of the Soviet Union requested the installation of a 152mm howitzer for the KV-1 for four tests. The best designers of the KTZ Design Bureau were called to complete the project. Two weeks later, a new pilot model was designed. At first the designer decided to install the 152mm mod1909/1930 howitzer, which was replaced by the more modern 152mm M-10 Model 1938/1940 howitzer. The new, larger turret was also designed to accommodate this heavy-duty gun, which was named MT-1. The name "KV-2" was given as it was officially incorporated into the military, and Soviet soldiers called it a "fearless warship." It has a powerful firepower with a 152mm howitzer, and its huge body is called the "giant" by the Germans.From 1940 to 1941, a total of 202 KV-2 tanks (including trial production models) were produced.I once created a miracle that blocked a tank from a tank!
