The Indian Air Force (IAF) finds itself in a challenging position, forced to extend the service life of its aging MiG-21 Bison fighter jets beyond their planned retirement date of December 2025. This decision comes as a result of delays in the induction of the indigenously developed Tejas Mk1A, which was intended to replace the MiG-21s.
The IAF had envisioned establishing its first Tejas Mk1A squadron by July 2024 at Nal Air Force Base in Rajasthan. However, production setbacks, primarily caused by delays in engine supply, have hindered Hindustan Aeronautics Limited's (HAL) ability to meet this timeline.
The MiG-21 Bison, despite undergoing various upgrades, has long exceeded its intended service life. While it boasts a storied combat history, participating in numerous conflicts and even shooting down a Pakistani F-16 in the 2019 Balakot airstrikes, it has also garnered the grim nickname "flying coffin" due to a high number of accidents and pilot casualties.
The Tejas Mk1A, with its advanced AESA radar, enhanced electronic warfare systems, and greater weapons-carrying capacity, represents a significant technological leap over the MiG-21. However, until its production and induction catch up to the planned schedule, the IAF has no choice but to continue operating the MiG-21 Bison, despite the inherent safety concerns.
This situation underscores the challenges faced by the IAF in modernizing its fighter fleet. Operating below its sanctioned strength of 42 squadrons, the IAF urgently needs new fighter jets to maintain operational readiness. The continued reliance on the MiG-21 Bison highlights the critical need to accelerate the production and delivery of indigenous platforms like the Tejas Mk1A.
HAL is actively working to resolve supply chain issues and increase production rates. In the meantime, the IAF is committed to ensuring the MiG-21 Bison fleet remains mission-capable. The extension of the MiG-21 Bison's service life, while a necessary stopgap measure, serves as a stark reminder of the importance of timely execution of indigenous defence programs to ensure the IAF's long-term capabilities and the safety of its pilots.
