MiG-15 success has allowed the OKB-155 to receive from the senior management of the country a kind of carte blanche for further improvement of this machine. So, IV. Stalin at the proposals of other fighter OKB on new aircraft types each time the object: "We have a good MiG-15, and there is no point in the near future to create new fighters, better to follow the path of modernization of MiG…"Moving in this direction, EDO team launched the modernization of MiG-15.

MiG-15 was taken to finalize the engine VC-1. The upgraded machine, except the trade name "SI", It was known as the MiG-15bis 45. Designers had to tie a new wing to the load-bearing frames of the fuselage MiG-15. As a result, obtained the double wing sweep of the leading edge: from the onboard rib semispan to about - 49 °, and then - 45,30 °. The front part of the fuselage left unchanged, extended back to 900 mm, introduced airbrakes increased area, Keel also slightly increased. Horizontal tail carried out again and found the ventral ridge. Armament fighters was similar armament of the MiG-15bis.
In July 1949 g. factory number 155 completed assembly of the first copy of "SI", however LII airfield passed until the end of the year. Test pilot was appointed I.T. Ivashchenko, who joined in the bureau in 1945 g. The first flight of the prototype took place 14 January 1950 g. At the beginning of factory testing has been established, maximum speed "SI" is greater than the MiG-15bis rate of approximately 40 kmh. 1 February 1950 g. in the next flight at a height of Ivashchenko 2200 m dispersed aircraft to a speed 1114 kmh. Soon, at the height of 10 200 m able to get the maximum speed 1077 kmh, that corresponds to the number M = 1.0. 20 Martha 1950 g. aircraft crashed. The plane went into a steep dive, and, despite all his experience, Ivashchenko could not cope with the situation. The plane crashed into the ground at high speed. pilot killed, and the car were only small fragments.
Continued testing of the MiG-15 military test pilot GA. Sedov, who joined in the bureau of the Civil Code of the Air Force Research Institute. During the tests, the aircraft collided with Sedov aileron reversal due to insufficient rigidity of the wing. After completions in April 1951 g. the aircraft was transferred to the state tests in GK Research Institute of the Air Force, that ended 8 August. In the final act of the Commission recorded: "Modified MiG-15bis with wing sweep 45 ° and a new tail has an advantage over a serial MIG-15".
Order of MAP 1 September 1951 g. instructed to begin production of the MiG-17 to five plants. During the production of fighter design repeatedly being finalized. Serial machines could carry two bombs on the locks of 50 or 100 kg. New brake pads of different shapes and areas have been established. From the end 1953 g. were installed ejection seats with curtain, thus expanding the range of emergency escape. On the basis of the MiG-17 combat and experienced several modifications were built. The plane was built in series for more than 30 years, not only in our country, but also abroad (Poland and China). He participated in two dozen wars and numerous armed incidents. All were released 10 367 MiG-17 (in our country 7999 pcs) various modifications.
