Tupolev Tu-80 - The Tupolev Tu-80 was a Soviet prototype for a longer-ranged version of the Tupolev Tu-4 bomber built after World War II. It was canceled in 1949 in favor of the Tupolev Tu-85 program which offered even more range. The sole prototype was used in various test programs before ending its days as a target.
