Rolled out of factory in October 1934. When restored after crash-landing on October 31 ANT-40.1 became a testbed for new technologies, including retractable ski gear. Second round of the factory trials took place in February 5 - July 31 1935. Wing are was decreased (while the span remained the same).
It did not became a series aircraft because the ANT-40.2 with Hispano-Suiza 12Y was considered more promising.
ANT-40.2 (SB-IS, where IS stays for Russian spelling of Hispano-Suiza) was finished at the very end of 1934 (or January 15 1935??) , and during flight tests in January 1935 speed 430km/h was demonstrated.
It was the first Soviet aircraft to be equipped with weight-compensated elevones. After minor changes (engines moved forward by 10cm, wing leading edge sweep increased from 4.5° to 9°) aircraft was adopted as a base for mass production series.
The SB series became a major bomber of the Red Army Airforce for next 5 years, used in several wars: clashes with Japanese on Mongolian border, Spanish War, Winter War, Great Patriotic War (WWII).
