The MiG-21 and F-4 Phantom II represent two distinct approaches to fighter aircraft design during the Cold War period. The MiG-21, manufactured by Mikoyan-Gurevich in the Soviet Union, conducted its maiden flight in 1955 and entered service in 1959. This single-engine, delta-wing aircraft was engineered as a lightweight interceptor capable of Mach 2+ speeds, with a focus on simplicity and cost-effective mass production.
Over 11,000 units were eventually manufactured, making it one of the most widely produced supersonic fighters in history. The F-4 Phantom II, developed by McDonnell Aircraft Corporation (later McDonnell Douglas), first flew in 1958 and entered U.S. Air Force service in 1963.
This twin-engine, twin-seat aircraft was designed as a multi-role platform capable of air superiority, ground attack, and reconnaissance missions. The F-4 featured advanced radar systems, could carry a substantial weapons payload of up to 18,650 pounds, and achieved a maximum speed of Mach 2.23. During the Vietnam War (1955-1975), these aircraft frequently engaged in combat operations.
The North Vietnamese Air Force operated MiG-21s primarily in interceptor roles against U.S. bombing formations, while American F-4 Phantoms served in both air-to-air combat and ground attack missions. The F-4 became the primary fighter-bomber for U.S.
forces, with over 5,000 units produced across all variants. Both aircraft continued to serve with various air forces worldwide for decades, with some remaining operational today.
