The BA-I (sometimes BAI) is a Soviet three-axle armoured car. Only 82 vehicles^[1] 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.
