MiG 21 vs Tejas : The MiG-21 and Tejas are two iconic fighter aircraft from India’s aviation history, representing different generations of combat aircraft. The MiG-21, known as the “Fishbed,” has been a workhorse of the Indian Air Force (IAF) for several decades, while the Tejas, India’s indigenous Light Combat Aircraft (LCA), represents the country’s aspirations for self-reliance in defense production. In this article, we’ll compare these two aircraft in terms of design, performance, and their roles in India’s air defense.
MiG 21 vs Tejas Detail Comprision
Design and Development:
MiG-21: The MiG-21, designed by the Soviet Union, first flew in the 1950s and quickly became one of the most widely produced and exported supersonic fighter aircraft. It played a pivotal role in several conflicts worldwide and was in service with the IAF for over five decades. While it was a formidable aircraft in its time, its design and avionics became outdated over the years.
Tejas: The Tejas, designed and developed by India’s HAL (Hindustan Aeronautics Limited), represents a leap in indigenous defense production. It is a fourth-generation multirole fighter designed to meet the IAF’s modern requirements. The Tejas program faced several developmental challenges, but it has steadily matured into a capable aircraft.
Performance and Speed:
MiG-21: The MiG-21 had a top speed of around Mach 2 (twice the speed of sound) and good climb rates. However, its limited range and outdated avionics put it at a disadvantage in modern aerial combat.
Tejas: The Tejas is designed to achieve speeds of around Mach 1.6 and has a modern avionics suite. While it may not match the top speeds of the MiG-21, it offers better overall performance and maneuverability.
MiG-21: The MiG-21 had a limited operational range, making it less effective for long-distance missions.
Tejas: The Tejas features improved range capabilities, allowing it to undertake a broader range of missions, including beyond visual range engagements.
Weapons and Armament:
MiG-21: The MiG-21 was equipped with a 23mm twin-barrel cannon and could carry a mix of air-to-air and air-to-ground munitions. However, its limited payload capacity restricted its versatility.
Tejas: The Tejas is armed with a 23mm GSh-23 twin-barrel cannon and can carry a wide range of modern weaponry, including Beyond Visual Range (BVR) missiles, precision-guided munitions, and air-to-ground missiles.
Avionics and Sensors:
MiG-21: The MiG-21’s avionics were basic by modern standards, with limited radar and targeting capabilities.
Tejas: The Tejas is equipped with advanced avionics, including an AESA radar, Electronic Warfare (EW) suite, and modern sensor fusion, enhancing its situational awareness and combat effectiveness.
Role in Air Operations:
MiG-21: The MiG-21 served primarily as an interceptor and point defense fighter during its heyday. It played a significant role in the 1971 India-Pakistan war and other conflicts.
Tejas: The Tejas is designed as a multirole fighter, capable of air superiority, ground attack, and reconnaissance missions. It aims to provide the IAF with a versatile platform for modern warfare.
Impact on Modern Warfare:
The Tejas represents India’s shift towards indigenous defense production and self-reliance. While the MiG-21 had its glory days, the Tejas is better suited to meet the challenges of modern air warfare. Its advanced capabilities and versatility make it a valuable asset for India’s defense forces.
