Though the MiG-17 still strongly resembles its forebear, it had an entirely new thinner and more highly swept wing and tailplane for speeds approaching Mach 1. While the F-86 introduced the "all-flying" tailplane which helped controllability near the speed of sound, this would not be adopted on MiGs until the fully supersonic MiG-19. The wing had a "sickle sweep" compound shape with a 45° angle like the U.S. F-100 Super Sabre near the fuselage (and tailplane), and a 42° angle for the outboard part of the wings. The stiffer wing resisted the tendency to bend its wingtips and lose aerodynamic symmetry unexpectedly at high speeds and wing loads.
