F-35 Lightning II vs. MiG-21

The Lockheed Martin F-35 Lightning II is a family of single-seat, single-engine stealth multirole combat aircraft developed by Lockheed Martin, with principal partners Northrop Grumman and BAE Systems. Designed to perform air superiority and strike missions, it also provides electronic warfare and intelligence, surveillance, and reconnaissance capabilities. The F-35 has three main variants: the conventional takeoff and landing F-35A, the short take-off and vertical-landing F-35B, and the carrier-based F-35C​​.

Production History: The F-35 was the culmination of the Joint Strike Fighter (JSF) program, which merged various combat aircraft programs from the 1980s and 90s. It descends from the Lockheed Martin X-35, which in 2001 won the JSF competition over the Boeing X-32. The program has been supported by the United States, along with NATO and close U.S. allies. Despite the criticism for its size, complexity, and cost, the F-35 first flew in 2006 and entered service with the U.S. Marine Corps F-35B in July 2015, followed by the U.S. Air Force F-35A in August 2016 and the U.S. Navy F-35C in February 2019. Over 1000 units have been produced since 2006​​​​.

Design Features: The F-35 is known for its stealth capabilities, advanced sensor package, and electronic sensors like the Electro-Optical Distributed Aperture System (DAS) and the Electro-Optical Targeting System (EOTS). The F-35 is designed to replace aging fighter inventories such as the U.S. Air Force F-16s and A-10s, U.S. Navy F/A-18s, and U.S. Marine Corps AV-8B Harriers and F/A-18s​​​​.

Operational History: The F-35 first saw combat in 2018 with the Israeli Air Force. It is planned to be a cornerstone of NATO and U.S.-allied air power, with the U.S. planning to buy 2,456 F-35s through 2044. The aircraft is expected to operate until 2070. It is designed to provide pilots with unsurpassed situational awareness, positive target identification, and precision strike in all weather conditions​​.

F-35 Lightning II vs. F-22 Raptor

Stealth and Air Superiority: While both aircraft offer advanced stealth capabilities, the F-22 is optimized for air superiority with higher maneuverability and speed. In contrast, the F-35 emphasizes multirole flexibility, with superior sensor fusion and strike capabilities.

Network-Centric Warfare: The F-35 is designed from the ground up for network-centric warfare, with the ability to share information seamlessly with allied forces. The F-22 has significant data link capabilities but does not match the F-35's level of sensor integration and information distribution.

F-35 Lightning II vs. Su-57 "Felon"

Multirole Versatility vs. Air Dominance: The Su-57 is Russia's answer to fifth-generation capabilities, focusing on air dominance with some ground attack capabilities. The F-35, while capable in air-to-air combat, provides a broader multirole function.

Global Deployment and Support: The F-35 has seen widespread adoption among U.S. allies, benefiting from a multinational development program. The Su-57, while a technological showcase for Russia, has not achieved the same level of international deployment.

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.
