During 1936 the M-100 engine was modified, and later same year it was introduced on the SB bomber, resulting in SB-2M-100A modification. Some of series aircraft were equipped with 3-blade variable pitch (2 positions: takeoff and cruise) propellers VISh-2. Ceiling was increased by 1160m, takeoff became 150m shorter, climb rate increased, but maximum speed decreased slightly (4km/h).

During production several modifications were introduced in cockpit equipment, armament. Bomb bay was modified to allow both horizontal and vertical bomb storage.

Table presents data for aircraft with 2-blade fixed pitch propellers.

Modified SB-2M-100A with improved armament (new turret, better aiming device for the belly gun) was built and tested in May-June 1937. It had speed 412km/h and loaded weight 5810kg. Passed the tests, but did not enter series production.
