This model, operated by a crew of two, doubled the ANT-III's 50 horsepower (37 kW) with its new Bristol engine, and outperformed the ANT-V's 100 horsepower (75 kW) Fiat engine.
In 1930 the ANT-IV began regular trips between Cheboksar and Kanash, carrying mail and priority passengers.
The following year the ANT-IVs were overhauled with Soviet-produced M-11 radial aviation engines, allowing them to travel at 28 km/h.
In 1934, an ANT-IV was delivered aboard the Smolensk to Ualen where it helped rescue remotely stranded explorers from the icebreaker Chelyuskin.
