Mikoyan/Gurevich MiG-17Development: Only gradually did Western observers recognise the MiG-17 as not merely a slightly modified MiG-15 but a completely different aircraft. Even then it was generally believed it had been hastily designed to rectify deficiencies shown in the MiG-1 5’s performance in Korea, but in fact the design began in about January 1949, long before the Korean war. This was because from the first the MiG-1 5 had shown bad behaviour at high speeds, and though the earlier fighter was eventually made completely safe (partly by arranging for the air brakes to open automatically at Mach 0-92) it was still a difficult gun platform due to its tendency to snake and pitch. The MiG-17 – which was probably the last fighter in which Gurevich played a direct personal role — had a new wing with thickness reduced from 11 per cent to about 9 pet cent, a different section and planform and no fewer

three fences. Without taper and with inboard sweep of 47° this made a big difference to high-Mach behaviour, and in fact there are reasons to believe the MiG-17 can be dived to make a sonic bang. With a new tail on a longer rear fuselage the transformation was completed by considerable revision of systems and equipment, though at first the VK-1 engine was unchanged. In 1958 the first limited all-weather version, the -17P, went into modest production with longer nose housing the same Izumrud (”Scan Odd") Al radar and ranging avionics as was also in production for the MiG-19. With the introduction of an afterburning engine the airbrakes were moved aft of the wing, away from the hot back end, but this was not a good position and they were returned (in enlarged rectangular form) to the tail in the most important sub-type the -17F. This was made in Poland as the Lim-5P (the -5M being a rough-field close-support version with larger tyres and drag chute), in Czechoslovakia as the S-104 and in China as the F-4. The PF was the afterburning all-weather version, and the final model was the PFU with guns removed and wing pylons for four beam-riding "Alkali" air-to-air missiles. Total production for at least 22 air forces must have considerably exceeded 5.000, exports from China alone exceeding 1,000. Many 17F remained in use in the mid-1970s.
