This video is a World War 2 Soviet aviation film highlighting the Tupolev SB2 high speed bomber.

It was numerically the most important bomber in the world in the late 1930s, and it was the first modern stressedskin aircraft produced in quantity in the Soviet Union. Many versions saw extensive action in Spain, the Republic of China, Mongolia, Finland and at the beginning of the War against Germany in 1941.
