Maa	URSS
Rooli	Yliäänisuihkuhävittäjäkoneet
Ensimmäinen lento	14. helmikuuta 1956
Rakennettu	11496

Nniiden Mikojan-Gurevitš MiG-21 on yliääninen suihkuhävittäjä, jonka on suunnitellut Mikojan-Gurevich Design Bureau Neuvostoliitossa. Se sai suositun lempinimen "Balalaika", koska puolalaiset lentäjät muistuttivat lentokoneen planform-näkymää, joka muistutti venäläistä kielisoitinta tai lyijykynää sen rungon muodon vuoksi.

The Mach 2 Revolution

Nniiden MiG-21F was the first major production variant of the legendary MiG-21 family. Designed as a short-range, high-altitude “point defense” interceptor, it was built for speed and climb rate above all else. Its iconic delta-wing and pencil-like fuselage made it a symbol of Soviet air power during the Cold War. While early versions like the “F” (Forsirovannyy – Uprated) were limited in terms of radar and fuel, they established the “lightweight fighter” philosophy that would challenge Western air superiority for decades.

Engineering the Pencil with Wings

The Shock Cone (Translating Inlet): To fly at Mach 2, the MiG-21 used a circular nose intake with a moving center cone. This cone automatically adjusted its position based on speed to manage the shock waves and ensure the engine received air at subsonic speeds.
Delta-Wing Aerodynamics: The 57-degree swept delta wing provided low drag at supersonic speeds and a large surface area for lift, though it caused the aircraft to lose energy rapidly during hard, high-G turns.
The “F-13” Transition: The most famous early sub-variant, the MiG-21F-13, removed one of the two internal 30mm cannons to save weight and make room for the K-13 air-to-air missile, a Soviet reverse-engineered version of the American Sidewinder.
Simple Ejection System: Early MiG-21s featured a unique “canopy-shield” ejection system where the canopy would stay attached to the seat to protect the pilot from the supersonic windblast before falling away.

Combat Legacy: Vietnam and Beyond

The Vietnam Threat: North Vietnamese MiG-21Fs used “hit-and-run” tactics against U.S. strike packages. Their small size made them difficult to spot visually, and their high climb rate allowed them to ambush F-4 Phantoms from below or above.
The “Pilot’s Plane”: Pilots loved the MiG-21 for its responsiveness and speed, but criticized its poor rearward visibility and the “nose-heavy” handling when low on fuel.
Mass Production: Over 11,000 MiG-21s were built (including Chinese J-7 copies). It has served in the air forces of over 60 nations and remains in active service in several countries today, more than 60 years after its debut.
The “MiG-21 Bis” Evolution: Later versions eventually solved the fuel and radar issues of the “F” model, adding a massive “spine” fuel tank and sophisticated radar, though this increased weight and reduced the pure agility of the original design.
