The BA-I (sometimes BAI) is a Soviet three-axle armoured car. Only 82 vehicles of this type were built in 1932–1934, nevertheless the design initiated a series of heavy armoured cars of Izhorskij plant: BA-3, BA-6, BA-9, and BA-10. Some vehicles were used in World War II, despite being obsolete at the time.

==Background== In 1931, the first Soviet 6x4 chassis was created, a design based on adding Timken tandem rear axles to the American Ford AA chassis, and because of that called Ford-Timken. This immediately initiated the development of armoured cars. By the end of the year assembly was taking place at the plant "Gudok Oktyabrya" in Kanavin, near Nizhniy Novgorod. In autumn of the same year at the Repair Base of Nº2 in Moscow hull from the BA-27 armoured car was first attached to the new chassis. About 20 such cars were built, having the designation BA-27M. At the same time, and with the same chassis, but at the Izhorskij plant, several dozen D-13 armoured cars were built, developed by N. I. Dyrenkov.
