Origen

Mikoyan-Gurevich MiG-21 (Russian: ?????? ? ??????? ??? - 21, NATO designation: Fishbed) - is a fighter jet, originally built by the Mikoyan-Gurevich design bureau in the Soviet Union. It was popularly known by Polish pilots as "balalaika", given its similarity to this stringed instrument of Russian origin. Approximately 12,000 were produced, including around 2000 copies of its many variants.[2] It is the second most produced military aircraft after World War II, after the Lockheed C-130 Hercules. The first versions are considered as second generation fighters, while the latest versions are considered third generation fighters. Around 50 countries on four continents used the MIG-21 and it is still in service with many nations, half a century after its maiden flight. This aircraft set records: at least in name, it is the most produced supersonic aircraft ever in the history of aviation, and the most produced combat aircraft after the Korean War, and is also the combat aircraft with the longest production run ever, taking into account its different versions (1959-1985). In 1966, through Operation Diamond, the Mossad took to Israel a MiG-21 stolen from the Iraqi air force and, the reverse engineering of which it was subject, revealed technological secrets that were shared by the Israeli and American air forces.[3]
