Ivanovich "Ayrtom" Mikoyan (Artem Mikoyan) and Mikhail Gurevich started their own design bureau after leaving Polikarpov. In 1939 they designed the Mikoyan-Gurevich MiG-1 in 1939 to meet a Soviet Air Force Requirement.
The MiG-1 was constructed of steel tube and wood.
The wing on the MiG-1 was low in the fuselage.
The landing gear were retractable.
The I-61 prototype flew in the spring of 1940 / March 1940.
The MiG-1 prototype, the I-200, was first flown on April 5, 1940. It took only 100 days from when the drawings were completed until it was built.
The prototypes showed poor characteristics but the MiG-1 was ordered for production.
