GE to Double F404 Engine Output for HAL by 2027
In a major boost to India’s indigenous fighter jet program, GE Aerospace has committed to ramping up production of the F404-IN20 engines to 24 units per year by 2027. These engines power the Tejas Mk1A fighter jets being produced by Hindustan Aeronautics Limited (HAL), a crucial part of India’s push for self-reliance in defense manufacturing.
GE to Ramp Up F404 Engine Production
The decision follows a previous 14-month delay in F404-IN20 deliveries, which had adversely impacted the Tejas Mk1A production timeline. The F404-IN20 engine is a high-thrust derivative of GE’s proven F404 platform, delivering 84 kN thrust and featuring improved components such as a higher-flow fan, Full Authority Digital Engine Control (FADEC), and single-crystal turbine blades.
This engine is uniquely suited for the Tejas Mk1A, a light combat aircraft designed for the Indian Air Force (IAF). GE’s increased output will ensure HAL can maintain its production targets and avoid further delays in aircraft delivery.
Boost to Tejas Mk1A Deliveries and IAF Modernization
Under a ₹48,000 crore contract signed in 2021, the IAF ordered 83 Tejas Mk1A fighters, with another 97 aircraft reportedly in the procurement pipeline. HAL is targeting a production rate of 24 jets per year to fulfill both orders by FY2031–32. A steady supply of F404-IN20 engines is critical for this schedule.
Any disruption could significantly impact IAF squadron strength, which is projected to fall to just 27 by 2032 if aircraft deliveries lag. The increased engine output will also help accommodate the additional order, raising the total fleet to 180 aircraft—essential for maintaining air superiority in the region.
Deepening the HAL-GE Strategic Partnership
This production ramp-up strengthens the long-standing HAL-GE collaboration, which also covers the co-development of the more powerful F414 engines for the upcoming Tejas Mk2 and the fifth-generation Advanced Medium Combat Aircraft (AMCA). An agreement signed in 2023 includes 80% technology transfer from GE to HAL for F414 engine production, aligning with India’s ‘Make in India’ and defense self-reliance objectives.
The F414 engine will enable future platforms to surpass current performance limits and provide critical technological edge amid regional threats from both Pakistan and China.
