Laville DI-4 (Russian: Лавиль ДИ-4) was a prototype two-seat fighter aircraft developed in the Soviet Union in the 1930s. The chief designer Henri Laville was one of several French aviation specialists invited to work in the Soviet Union and not surprisingly the DI-4 layout was typical of the French trend at the time with a high-mounted gull wing (first for a Soviet aircraft) and all-metal construction.
