The Mikoyan-Gurevich MiG-21 is a supersonic jet fighter aircraft, designed by the Mikoyan-Gurevich Design Bureau in the Soviet Union. It was popularly nicknamed “Balalaika”, from the aircraft’s planform-view resemblance to the Russian stringed musical instrument or pencil by Polish pilots due to the shape of its fuselage.

The Mach 2 Revolution
The 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.
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.
