History
The Polikarpov U-2 biplane was designed and built during 1928 as a primary trainer for the fledgling Soviet Air Force, and it seemed to possess all of the characteristics desired by that service, including rugged all-wood construction, a low-powered but reliable power plant, and excellent flying characteristics. It was produced in massive numbers, approximately 40,000 of them eventually being manufactured in the Soviet Union and foreign countries. The type was adaptable to many uses, including training, air ambulance, night bombing, crop dusting, and a few were even used as floatplanes. During the war, the plane was re-designated Po-2 in honor of the designer, Nikolai Nikolaevich Polikarpov. A few were even used by the North Koreans during the Korean War for night harassment, as, having all-wood construction, they had a very low radar profile. There are still a few flying today, especially in Europe.
