A distinctive feature of the Soviet boats was their small size, and consequently, they had a small displacement and weak armor. But at the same time, they were able to develop high speed and good maneuverability. Basically this series of boats were the G-5 and Komsomolets. Based on these features, their methods of attack were developed. Observers could conclude that the Soviet boat actions could seem like madness at times, but they acted on the basis of the characteristics of their boats and on a correct assessment of enemy action.
