Number built One

The 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 the first high-mounted gull wing on a Soviet aircraft and all-metal construction.

The test flight program was completed in 1933 but despite good performance the aircraft did not enter mass production, in part because the Soviet Union had no plans to purchase the Curtiss V-1570 engine.[1]
