The Soviet MiG-17 fighter was built to be much more stable than its predecessor, The MiG-15 had been unstable at high rate and too tight a change may cause an uncontrolled snap roll and spin. To overcome this dilemma, the fuselage ended up being lengthened, little 'fences' were installed on the top surfaces regarding the wing to manage airflow, and also the wings swept back 45 levels. The additional space within the fuselage enabled the interior layout and systems become revised, and an even more angular end had been added. These changes provided the aircraft great security, needed for a fruitful weapons platform. The MiG-17 entered frontline service in February, 1953. The Fresco-A maintained the original VK-1 turbojet for the MiG-15. A VK -1F motor with afterburner had been then fitted to this new Fresco-C, or MiG -17F . A fixed-scan radar ended up being added to the MiG-17PF, or Fresco-D. The MiG-17PFU, Fresco-E, became the Soviet Union's very first interceptor with its cannon deleted and four air-to-air missiles included.
