“"The MiG-21’s delta wing and thirsty Tumansky turbojet mad..."”
The MiG-21’s delta wing and thirsty Tumansky turbojet made it a Mach 2 interceptor of ruthless simplicity. It served in the air forces of roughly sixty nations across four continents, and seven decades after its maiden flight it remains in limited service in several countries, notably India into the 2020s (Cuba’s MiG-21s are not currently conducting operational patrols). Guinness World Records recognises the type as the most-produced jet-powered military aircraft of all time[^17]. Its longevity is a study in pragmatic engineering: easy to build, easier to maintain, and lethal in the hands of a skilled pilot. In an era of stealth and sensor fusion, the MiG-21 endures as a reminder that numbers, too, are a form of airpower.
The engineering principles pioneered here—The MiG-21’s delta wing and thirsty Tumansky turbojet made it a Mach 2 intercept—are still embedded in the aircraft you fly today.
