quote: The Tupolev Tu-4 ... was a reverse-engineered copy of the U.S.-made Boeing B-29 Superfortress.The Soviet Union used the metric system, thus 1/16 inch (1.6 mm) thick sheet aluminum and proper rivet lengths were unavailable. The corresponding metric-gauge metal was thicker; as a result, the Tu-4 weighed about 3,100 lb (1,400 kg) more than the B-29, with a corresponding decrease in range and payload.
