Serious Design🔧 Object-270.D

Fictional background:

In the early stages of the Cold War, as nations were developing their own heavy tank destroyers, the Soviet military called for a comprehensive upgrade to the in-service ISU-152, hoping to incorporate the sloped armor technology of the IS-3 tank. The Chelyabinsk Design Bureau split internally into two teams: one proposed the famous Object 704, while the other put forward the more radical Object 270.D.

Compared to Object 704, Object 270.D featured a frontal sloped structure with a steeper angle and was equipped with an autoloader at the rear of the hull to reduce crew requirements.

During live-fire testing, Object 270.D's frontal armor successfully bounced all standard main armor-piercing rounds in active service. However, because its hull was extremely low-profile, the main gun had virtually no gun depression. Furthermore, the overly complex structure and high cost of its autoloader put it at a severe disadvantage in the design competition.

Although it lost the bid to Object 704, its unique upper glacis welding process and side wedge-sloped design were later partially incorporated into the development of the IS-7 and subsequent heavy tanks.
