E 77 historical reference
A nameless project for a heavy tank considered as an alternative to the E-series. It was planned to be equipped with a compact gas-turbine engine. The transmission would have been placed in the rear part of the vehicle and the turret would have been cast. Together, these features would have made it possible to reduce the tank's weight and mount a more powerful gun. According to reports of a Soviet committee working in Germany after World War II, German designers had also been actively working on mechanized loading. However, the end of the war put paid to many developments, including this nameless project, which could have become a dangerous opponent to the latest generation of Soviet tanks.
