Why in the news?

  • Recently, the Indian Air Force has been phasing out the MiG-21 fighter jet squadron with the phase-out expected to be completed by 2025.
  • The legacy jets will be replaced by the LCA Mark-1A manufactured by Hindustan Aeronautics Ltd (HAL).

MiG-21

What is the MiG-21?

  • The Mikoyan-Gurevich MiG 21 is a supersonic jet fighter and interceptor aircraft that was designed by the Mikoyan-Gurevich Design Bureau in the Soviet Union.
  • It is a single-engine, single-seater multi-role fighter/ground attack aircraft.
  • The MiG-21 has been used by around 60 countries on four continents.
  • Russia stopped producing the aircraft in 1985, while India continued operating the upgraded variants as it possessed full technology transfer and rights to license-build the aircraft in the country.

What role did the MiG-21 play?

  • India has procured over 700 MiG-21 aircraft of different variants such as the Type-77, Type-96 and the BIS.
  • The MiG-21 was inducted into the Indian Air Force in 1963 and became the frontline fighter jet of the IAF.
  • It was the first supersonic fighter introduced in the IAF’s service.
    • The No.4 squadron has served the country for around six decades and has significantly contributed to the Indo-Pak wars.
  • Since then, more than 800 variants of the supersonic fighter jet have been inducted into service and used in major conflicts.
    • For instance, the No.4 squadron has served the country for approximately six decades and has significantly contributed to the war effort during Indo-Pak conflicts.
  • The IAF has operated 24 fighter squadrons and four training units equipped with the MiG-21 with an average tenure of 33 years.
  • Six squadrons of MiG-21FLs participated in operations in both the Eastern and Western Sectors during the 1971 War of Bangladesh.
  • In the 1999 Kargil conflict, the MiG-21 was used in night operations.

Phasing out of the MiG-21

  • According to Air Chief Marshal, Vivek Ram Chaudhary, India will stop flying the MiG-21 fighter aircraft by 2025 and replace it with the MiG-21 squadron with the indigenous Light Combat Aircraft (LCA)-Mk1A.
  • In 2022, the No. 51 squadron ‘Swordarms’ based in Srinagar which participated in the aftermath of the Balakot air strike was phased out.
    • It was raised in 1985 and initially equipped with MiG-21 Type 75 aircraft before being upgraded to the MiG-21 Bison in 2004.

Reasons for the replacement

  • Fleet modernization: The IAF aims to phase out the MiG-21 as part of its modernization drive.
    • In 2022, the Union Ministry of Defence sealed a ₹48,000 crore deal with Hindustan Aeronautics Ltd (HAL) for the procurement of 83 Tejas fighter aircraft.
    • The IAF is also aiming to procure 114 Multi-Role Fighter Aircraft (MRFA).
    • India is also working on an ambitious $5 billion project to develop a fifth-generation medium-weight deep penetration fighter jet to significantly bolster its air power capability.
  • Accidents: Since 1963, the MiG-21 fleet experienced more than 400 accidents which led to the deaths of around 200 pilots.
    • The high rate of accidents resulted in it being nicknamed the ‘Flying Coffin”.

What is the replacement?

  • The IAF has inducted two squadrons of the LCA Tejas and two squadrons of Rafale fighter jets to increase the IAF’s squadron strength to more than 30.
  • The LCA-Mk1A will form the bulk of the force as the other jets will take time to be inducted.
  • India is looking to procure an additional 97 LCA-Mk1A at an estimated cost of ₹67,000 lakh crore, making a total of 180 Mk1A variants.
