Introduction

The Mikoyan-Gurevich MiG-21 is one of the most iconic fighter jets in aviation history. Designed during the Cold War era, this Soviet-origin aircraft became the world’s most produced supersonic jet and served in the air forces of more than 60 countries. Known by NATO as “Fishbed,” the MiG-21 combined exceptional speed, agility, and cost-effectiveness, making it a favorite among pilots and defense strategists.

For India, the MiG-21 holds a special place as it became the backbone of the Indian Air Force (IAF) for over five decades. From guarding the skies during critical wars to being a reliable training platform, the MiG-21 shaped modern Indian aerial warfare and contributed to national security for generations.

Origins and Development

The MiG-21 was developed by the Soviet design bureau Mikoyan-Gurevich in the early 1950s. Engineers Artem Mikoyan and Mikhail Gurevich sought to create a lightweight fighter that could achieve Mach 2 speeds while remaining easy to produce. The first prototype, designated Ye-1, flew in 1955, showcasing a revolutionary delta-wing design. After several test flights and refinements, the production variant MiG-21F entered service with the Soviet Air Force in 1959.

Its distinctive triangular delta wings allowed for excellent climb rates and high-speed performance, though they demanded careful handling at low speeds. The aircraft’s simplicity, combined with advanced radar and missile systems for its time, made it an attractive export product for Soviet allies across Asia, Africa, and Europe.

Introduction to India

India’s quest for a modern supersonic fighter in the late 1950s led to a historic defense collaboration with the Soviet Union. After evaluating multiple Western and Eastern aircraft, the Indian Air Force selected the MiG-21 in 1961 for its speed, affordability, and upgrade potential. The first batch of MiG-21F-13 aircraft arrived in India in 1963, marking the country’s entry into the supersonic era.

A landmark agreement followed between India and the USSR for licensed production. Hindustan Aeronautics Limited (HAL) set up manufacturing lines in Nasik, Maharashtra, allowing India not only to assemble but eventually to produce the MiG-21 indigenously. This collaboration helped strengthen India’s aerospace industry and reduced dependence on foreign suppliers.

Production and Manufacturing

Globally, more than 11,000 MiG-21s were produced, making it the most manufactured supersonic jet ever. In India, HAL produced several upgraded variants under license, including the MiG-21FL, MiG-21M, and MiG-21bis. Production in India continued for decades, with the final aircraft rolling out in the mid-1980s. HAL’s Nasik division became a hub for not just assembly but also research, upgrades, and maintenance, enabling the Indian Air Force to operate a large fleet with self-reliance.

MiG-21 in Indian Wars

The MiG-21 became India’s first line of defense in multiple wars and conflicts. Its role in shaping the Indian Air Force’s combat reputation cannot be overstated. Despite being lightweight, it often went head-to-head with advanced enemy aircraft and proved its worth on the battlefield.

Indo-Pak War of 1965

The MiG-21 entered combat for the first time during the Indo-Pak war of 1965. Although inducted shortly before the war, it still saw limited action due to operational training stages. However, its mere presence gave India a supersonic edge over Pakistan, which relied on the American-supplied F-86 Sabres and F-104 Starfighters.

Indo-Pak War of 1971

By 1971, the MiG-21 fleet had grown in strength and was fully operational. In this decisive war that led to the creation of Bangladesh, the MiG-21 became the star performer. The IAF used MiG-21s in both air superiority and ground attack roles. Pakistani F-104 Starfighters, considered technologically superior, were shot down in dogfights, proving the MiG-21’s agility and missile capabilities.

One of the most famous encounters was when Flight Lieutenant Bharat Bhushan Soni shot down a PAF F-104 Starfighter using an air-to-air missile, demonstrating the MiG-21’s lethality.

Kargil War 1999

During the Kargil conflict, MiG-21s were deployed for ground attack and reconnaissance missions. Though older by this time compared to modern jets, they played a significant role in providing close air support to Indian Army troops fighting at high altitudes. The aircraft faced challenges due to advanced surface-to-air missiles but continued to operate under difficult conditions.

Balakot Airstrike (2019)

The MiG-21 entered headlines again in 2019 during the Balakot airstrike aftermath. In a dogfight on February 27, Wing Commander Abhinandan Varthaman flying a MiG-21 Bison engaged Pakistani F-16s. Despite the technological disadvantage, Abhinandan shot down an F-16 before his aircraft was lost. This was an extraordinary moment in modern aerial combat history, highlighting the MiG-21’s continuing relevance even six decades after its introduction.

International Collaborations

India acquired the MiG-21 under a 1962 Indo-Soviet agreement that allowed licensed production in India. This collaboration extended beyond just manufacturing; it helped India build technical know-how, maintenance capability, and defense independence at a time when Western powers were reluctant to share technology.

The collaboration with the Soviet Union marked the beginning of a long-lasting defense partnership that would later see advanced aircraft like MiG-29s, Su-30MKIs, and modern missile systems supplied to India.
