MiG-21 vs. Sukhoi Su-27

The Mikoyan-Gurevich MiG-21, known by its NATO reporting name "Fishbed," is one of the most produced jet fighters in aviation history, with over 11,000 units built by the Soviet Union from 1959 into the 1980s. This aircraft served as the backbone of the Soviet Air Force and its allies throughout the Cold War, making it one of the most widely exported fighters ever, used by over 60 countries across four continents.

Production History: The development of the MiG-21 began in the early 1950s, with the first prototype taking flight in 1956. It was introduced into service in 1959, marking a significant leap in Soviet fighter technology with its Mach 2 capabilities. The MiG-21 was continuously improved and produced in various versions, including interceptor, fighter-bomber, and reconnaissance variants.

Design Features: The MiG-21's design is characterized by its delta wing and unique fuselage, which houses a single Tumansky turbojet engine. This configuration provided the aircraft with excellent speed and agility. The aircraft's relatively small size and simple design also contributed to its low production and maintenance costs. Despite its compact frame, the MiG-21 was capable of carrying a range of weapons systems, including air-to-air missiles, bombs, and an internal autocannon.

Operational History: The MiG-21 saw extensive combat use in several conflicts during the latter half of the 20th century, including the Vietnam War, where it engaged in dogfights with American F-4 Phantoms and F-105 Thunderchiefs. The aircraft continued to see action in various regional conflicts around the world, proving its effectiveness in both air-to-air and air-to-ground roles.

MiG-21 vs. F-4 Phantom II

Role and Capabilities: While both aircraft were primary fighters of their respective air forces during the Vietnam War, the MiG-21 was lighter, faster, and more agile, designed for quick intercept missions. In contrast, the F-4 Phantom II was a larger, more versatile fighter-bomber capable of performing a wide range of missions.

Performance: The MiG-21's design focused on high-speed interception and agility, making it especially effective in close-range dogfights. The F-4, however, had a greater payload, longer range, and was equipped with advanced radar and missile systems, allowing it to engage enemies beyond visual range effectively.

MiG-21 vs. F-5 Freedom Fighter/Tiger II

Design Evolution: Both aircraft were developed around the same time and shared roles as lightweight, cost-effective fighters for their respective allies. The F-5 was designed with a focus on ease of maintenance and versatility, while the MiG-21 was optimized for speed and altitude performance.

Operational Capabilities: The MiG-21 and F-5 were considered well-matched adversaries, with similar sizes and speeds. However, the MiG-21's delta wing provided it with a slight edge in maneuverability at higher speeds, whereas the F-5 offered better visibility and weapon accuracy at lower speeds.

The Sukhoi Su-27 "Flanker" is a highly maneuverable, twin-engine supersonic fighter aircraft developed by the Soviet Union and introduced into service in the early 1980s. Designed primarily for air superiority missions, the Su-27 was a direct response to U.S. fourth-generation fighters such as the F-15 Eagle.

Production History: Development of the Su-27 began in the early 1970s, with the first prototype taking flight in 1977. Its introduction into service in 1985 marked a significant advancement in Soviet air combat capabilities, with production continuing into the 1990s. The Su-27 platform has spawned a number of variants and developments, including the Su-30, Su-33, Su-34, and Su-35, each tailored for specific mission profiles ranging from long-range interception to ground attack.

Design Features: The Su-27 features a large airframe with a distinctive blend of integrated forebody and wing, known as a blended wing-body design, which contributes to its high lift and agility. Powered by two Saturn AL-31 turbofan engines, it is capable of reaching speeds over Mach 2. The aircraft is equipped with a sophisticated radar and fire-control system, allowing it to engage multiple targets simultaneously with a variety of air-to-air missiles.

Operational History: The Su-27 has been actively involved in numerous military engagements and exercises since its introduction. Its combat debut occurred in the Ethiopian-Eritrean conflict, where it demonstrated superior air combat capabilities. The Su-27 has also been involved in patrolling and air defense missions in several regions, showcasing its versatility and effectiveness as an air superiority fighter.
