The Polikarpov TB-2 (Russian: Поликарпов ТБ-2) was a Soviet heavy bomber prototype designed and tested in the 1920s. It was a wooden-construction sesquiplane with engines mounted on the bottom wing. Work on the sole prototype began in 1927 and it was tested in 1930. Although TB-2 performance was superior to that of the Tupolev TB-1 in service at the time it was deemed insufficient for 1930 and the project was abandoned.
