Development of the IS-1, planned as a pre-production aircraft. The IS-2 had a smaller-diameter (and more powerful) engine and generally cleaned up lines. It was flown, but did not enter trials program. Analysis suggested that wing area should be decreased to 17m2 (or even to 14m2). But in this case all advantages in takeoff/landing were too small to justify extra weight of the wing retraction mechanism .

Concerns remained also about the complexity and vulnerability of the wing retraction mechanism.
