The first known example of a successful attack of air-to-air rockets on another plane took place on August 20, 1939, during the Battle of Khalkhin Gol. A group of Soviet Polikarpov I-16 fighters under command of Captain N. Zvonaryev successfully destroyed a few Japanese warplanes by launching of RS-82 rockets. Soviet RS-82 rockets were mounted on special pylons under wings of Soviet fighters.[4]
