Development of the SB-2M-103 featuring new engine cowling with tunnel variable intake radiators instead of the 'honeycomb' ones. Water-oil cooling circle was replaced by air-oil.
Test continued November 1, 1937 - January 17, 1938. Speed was increased, but aircraft required serious refinement. Those modifications continued through 1938, with few small series of SBbis3 built during this period.
In 1939 this aircraft took its final shape. Air intakes chosen fixed ones, leading edges of the wing and tail surfaces were polished. Variable pitch propellers became a standard (VISh-2, later - VISh-22).
