Quick Summary

The MiG-21 is a lightweight, single-engine Soviet interceptor aircraft developed by the Mikoyan-Gurevich design bureau. First flown in 1955 and entering service in 1958, it was capable of flying at twice the speed of sound. The basic version was a simple, low-cost day fighter that was highly maneuverable, easy to maintain, and could operate from unimproved airfields. It became a principal high-altitude interceptor for North Vietnam and formed the backbone of Arab air forces through the 1970s. The MiG-21 was produced in over 9,000 units across 32 versions for the Soviet Union and more than 40 other countries, with a licensed version also produced in China.12
