The Kalinin K-2 (Russian Калинин К-2) was a Soviet airliner designed and built by the designer Konstantin Kalinin. The aircraft was a variant of the predecessor K-1 with a stronger engine and an all-metal construction. The total weight of the construction exceeded that of the planning considerably. The first flight took place in 1926. The assembly was more complex than the K-1, but only four were built.
