MiG-21’s Last Roar: IAF Bids an Emotional Farewell to Its Supersonic Warhorse Today

Today, September 26, 2025, the MiG-21, India's most iconic supersonic fighter jet will roar across the skies one last time. For more than six decades, this Cold War marvel has been the backbone of the Indian Air Force

The MiG-21, the iconic supersonic jet fighter holds a unique place in aviation history. Designed by the legendary Soviet duo Artem Mikoyan and Mikhail Gurevich, it was the first Soviet aircraft capable of flying faster than twice the speed of sound.

Sleek, versatile and relentlessly innovative, the MiG-21 combined the roles of fighter and interceptor in a single platform, evolving from a high-altitude interceptor into a true multi-role aircraft. Over 11,400 MiG-21s were built globally, making it the most-produced supersonic jet aircraft ever, and it served in more than 60 countries.

Why the USSR Built the MiG-21

The MiG-21 emerged during the 1950s, at the height of the Cold War. The Soviet Union needed a lightweight, fast, and inexpensive fighter capable of intercepting high-speed American bombers, particularly the spy planes and strategic bombers like the B-52. It was intended to outmatch early American jets and to maintain parity with the United States in aerial warfare capabilities.

Mikoyan-Gurevich's design philosophy emphasized speed, simplicity, and mass production. The MiG-21 was built to be affordable, easy to maintain, and deployable in large numbers, allowing the USSR to project air power globally and supply allied nations with cutting-edge fighters.

The MiG-21 and Its U.S. Counterparts

In the United States, the MiG-21 was closely monitored by military analysts and regarded as a formidable adversary. Its American counterparts included aircraft like the F-104 Starfighter, F-4 Phantom II, and later the F-5 Freedom Fighter in the light supersonic category. The MiG-21's high-speed climb, delta-wing design, and manoeuvrability made it a challenging opponent in dogfights, particularly in Vietnam and the Middle East.

In conflicts like the Vietnam War, MiG-21s repeatedly challenged American air superiority, scoring kills against U.S. aircraft despite being outnumbered and sometimes technologically outmatched. This earned the aircraft both fear and respect among Western pilots, who referred to its pilots as highly skilled adversaries.

Technical Marvels

The MiG-21's design was as distinctive as it was functional. With its sharp needle-like nose, delta wings, and a narrow fuselage of just 1.24 meters in width, it was built for speed and agility. Early variants required pilots to accelerate to around 340 km/h just to take off, while later models incorporated advanced features such as:

· Moving nose inlet cones for optimal airflow at supersonic speeds.

· Powerful Tumansky R-25 engines

· Multiple air brakes for high-speed maneuvering

· Ejection systems that evolved over time to enhance pilot survival

· Lightweight structure enabling Mach 2 speeds

Its simplicity, reliability, and adaptability made it the backbone of Soviet Frontal air-defense forces, with thousands exported worldwide, cementing its global influence.

India's MiG-21 Journey

India was among the largest operators of the MiG-21. In 1961, the IAF selected the aircraft, with the USSR providing technology transfer and licensing rights for local production. The first IAF pilots trained in Kazakhstan on MiG-15 and MiG-17 aircraft before transitioning to the MiG-21.

The first MiG-21 squadron, No. 28 "First Supersonics," was raised in Chandigarh in 1963 under legendary Air Marshal Dilbagh Singh. While initial plans had suggested Adampur or Hindon as bases, Chandigarh offered practical advantages. The first batch of six jets and modest facilities quickly made the squadron operational, establishing Chandigarh as the birthplace of India's supersonic era.

Over the decades, India built around 600 MiG-21s under license via Hindustan Aeronautics Limited (HAL), and at its peak, the IAF operated around 400 jets across 19 squadrons. The MiG-21 played critical roles in the 1971 Indo-Pak war, the Kargil conflict of 1999, and the 2019 aerial engagement with Pakistan, cementing its legacy as India's trusted sky warrior.

The MiG-21's Strengths

The MiG-21 was a marvel of engineering, offering unmatched speed, agility, and versatility for its time. It could operate in multiple roles: high-altitude interception, ground strikes, reconnaissance, and pilot training. Its simplicity made maintenance manageable, and the aircraft's lightweight frame allowed supersonic performance that few contemporaries could match.

The Risks and Limitations

However, the MiG-21 came with challenges. Its short range, and tricky flight characteristics made it a demanding aircraft to operate. Pilots had little margin for error during take-offs and landings. Ejecting at supersonic speeds posed severe hazards, often resulting in spinal injuries. These factors, combined with a procurement lag in replacing aging squadrons, led to tragic losses: over 400 aircraft were lost in India, claiming more than 200 pilot lives.

Transition to Tejas and the Future

The long-awaited Tejas Light Combat Aircraft (LCA) was envisioned to replace the MiG-21, but development delays meant the supersonic stalwart continued in service far longer than planned. Today, with two Tejas Mark 1 squadrons operational and four Mark 1A squadrons on order, India is finally set to retire the MiG-21 legacy while ensuring a capable future with modern multi-role fighters.

A Legacy Remembered

From its first flights in Chandigarh to its final missions in 2025, the MiG-21 served India faithfully for over six decades. It was not just a fighter; it was a symbol of courage, and the relentless spirit of the Air Force. Despite its challenges and losses, it defended India's skies and trained generations of pilots.

As the MiG-21 bows out, it leaves behind an indelible mark on Indian aviation history. For decades of service, countless daring sorties, and unwavering dedication to the nation, we salute the MiG-21-India's legendary warhorse of the skies.
