MiG-21 vs. Sukhoi Su-57

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-57 "Felon" is Russia's first fifth-generation multi-role fighter aircraft, designed to have supercruise, supermaneuverability, stealth, and advanced avionics. Developed by Sukhoi Company (JSC), the Su-57 is intended to serve as the foundation of Russian air power for the future. Its development reflects Russia's aim to field a stealth fighter that can compete with Western models such as the F-22 Raptor and F-35 Lightning II.

Production History: The Su-57's development began in the early 2000s, with the first prototype, then known as the PAK FA (Prospective Aviation Complex of Frontline Aviation), taking to the skies in 2010. After an extensive testing and development phase, the aircraft was officially designated as the Su-57 and entered service in December 2020. The production aims to modernize the Russian Aerospace Forces with a platform capable of achieving air superiority and precision strike capabilities.

Design Features: The Su-57 features a unique blend of stealth characteristics, including internal weapon bays, radar-absorbent material, and a shape designed to minimize radar cross-section. It is powered by Saturn izdeliye 30 engines, enabling supercruise capability. The aircraft's design emphasizes advanced aerodynamics, allowing for exceptional agility and control at various speeds.

Operational History: Although relatively new to operational service, the Su-57 has already seen preliminary deployment in Syria for combat evaluation purposes. These deployments have allowed Russian forces to test the aircraft's performance in real-world conditions, evaluating its stealth, sensors, and weapons systems against a backdrop of active conflict.
