Tupolev TB-6 was a proposal for a 1930s heavy bomber that did not advance beyond blueprints. Inspired by the success of ANT-20-PS-124 Tupolev in 1929 began work on an even larger aircraft powered by 12 engines and with a takeoff weight of 70 tons (155 000 lb). A 1-20 scale two-seat glider was built and test-flown to evaluate the aerodynamic soundness of the design and work was started on the first prototype.
Made by Tupolev.
