Obiekt 140

Soviet experimental medium tank

The Obiekt 140, or Object 140, was a prototype medium tank developed from 1953 to 1958 in Nizhny Tagil, Russia to replace the T-54 medium tank. Two prototypes were completed before the project was cancelled in 1958 in favor of the Object 430 Project, which would become the T-64. Several features of the Object 140 design would find their way into the T-55 and T-62 designs.
