st-1

ST-I Soviet heavy tank (sometimes seen as ST-1)—both from concept art or digital renderings. The first image showcases its design as featured in World of Tanks material, and the second is from the official Tankopedia view, giving a clearer look at the conceptual silhouette. --- ST-I (also referred to as ST-1) – Soviet Heavy Tank Concept Historical Context & Origin The ST-I was a blueprint-only heavy tank project, developed in 1945 at Factory No. 92 by engineers V. A. Ganin and A. S. Chasovnikov, using the hull of the IS-4 (Object 701) with a newly designed turret . It never progressed beyond design documents—no prototypes were ever built . Design & Innovation Some versions of the design included a double-barrel turret, intended to greatly enhance fire accuracy and rate of fire by having two main guns supported by two loaders and a rapid-feed ammunition system . Ergonomically, the ST-I featured impressive design standards for its era: standing room for loaders was about 1680 mm, higher than virtually any WWII-era tank except perhaps the Churchill . In Gaming & Popular Culture The ST-I has appeared in popular tank combat games like World of Tanks and War Thunder, where it’s depicted as a Tier IX heavy tank with detailed stats and visual representation . Despite in-game portrayals, its true historical basis remains fictional—based solely on design drafts rather than real production . --- Summary Table Feature Details Origin Blueprint, 1945, Factory No. 92 Design IS-4 hull, new turret; some drafts with dual guns Ergonomics Impressive loader compartment height Reality Never built; purely a concept Cultural Impact Featured in tank-themed video games --- In short, the ST-I—or ST-1—was a forward-thinking Soviet heavy tank concept with advanced ergonomics and firepower potential on paper but remained on the drawing board. Its presence in popular media keeps the concept alive but historically, it's a "what-if"
