Development of the MiG-21 dates back to the early 1950s, when the Mikoyan design bureau was conducting development work on a design study for a new swept-wing jet aircraft. Further work on the project led to the creation of a seperate, delta wing prototype, designated ‘Ye-4’. With test flights showing promising results, but also much room for improvement, work on the Ye-4 resumed. Further tweaks and modifications to the design eventually lead to the Ye-5 prototype, which conducted its maiden flight in January 1956.

During testing, the Ye-5 received its new designation ‘MiG-21’ and was officially ordered into production. However, production of this initial batch of MiG-21s was rather short, with only a handful of machines being built. In the meantime, an improved version of the aircraft - the Ye-6 - was being worked on. By May 1958, testing of the Ye-6 was deemed to be completed. Shortly afterwards, in July, the Ye-6 was ordered into mass production under the designation MiG-21F and was to replace the initial MiG-21 as the standard production model. The aircraft weaponry consists of two 30 mm automatic cannons. The next step was to equip the aircraft with guided “air-to-air” missiles but in to do this one of the cannons had to be removed.

From there on, the MiG-21 would go on to be produced in enormous numbers and in various different variants, both for the needs of the Soviet Union, as well as for export. Around 60 countries have or still use the MiG-21 in various capacities and modifications today.

Well over 11,000 MiG-21s have been produced, including licence-built versions (more than 2,400 models were built in China under the J-7 designation), since the start of production in 1959, with the legendary ‘Fishbed’ becoming the most mass produced combat aircraft since the Korean War and taking part in more armed conflicts than a single devblog would ever be able to cover. But as an example we can mention its participation in the Vietnam War where the MiG-21 was able to push back against the latest U.S. aircraft (which were in majority).
