Danbooru の英語定義
The IS-6 is the fifth variant of the IS heavy tank family. It was never mass-produced and remained in the prototype stage. There was an effort to develop a replacement for the IS-2 in the closing years of World War II ('The Great Patriotic War' to the Soviets). The IS-6 (Object 252/Object 253) and IS-4 (Object 701) were created as a result of the development process. This effort was highly classified, with two competing factories creating their designs in complete secrecy for fear of exposing knowledge to one another.
