GE Aerospace has reaffirmed its dedication to India’s Light Combat Aircraft (LCA) Tejas Mk1A program, committing to a revised schedule that will see 12 F404-IN20 engines supplied to Hindustan Aeronautics Limited (HAL) by the close of 2025. This development is a significant encouragement for the indigenous fighter jet initiative.
The first of the 99 engines under contract was delivered on March 25, 2025. Despite a mutually agreed short pause in the delivery timeline, GE plans to ship two additional engines beginning in July.
This schedule is anticipated to enable HAL to make the Indian Air Force’s (IAF) first Tejas Mk1A squadron operational by the end of the year, a crucial move to address the nation's diminishing fighter squadron numbers.
The F404-IN20 engine, specifically adapted with high thrust for the Tejas Mk1A, is central to India's self-reliant fighter aircraft program.
The initial engine's delivery in March 2025 concluded an approximate two-year delay. This setback was attributed to worldwide supply chain disruptions and the challenges of restarting the F404-IN20 production line, which had been inactive since 2016 after fulfilling a previous order for 65 engines for the earlier Tejas Mk1 version. This first engine reached HAL facilities on April 3, 2025.
With a commitment to deliver two more engines each month starting from July, GE is set to provide a total of 12 engines by December 31, 2025. This figure includes the unit already delivered plus an additional 11 engines, aligning with HAL's target to manufacture at least eight Tejas Mk1A aircraft—comprising six fighters and two trainers—which is enough to establish the IAF's first squadron of 18 aircraft.
A brief interruption in deliveries, mutually decided by GE and HAL, was aimed at stabilising the supply chain. This chain had experienced difficulties due to the COVID-19 pandemic and a five-year interval in orders between 2016 and 2021.
Overcoming these obstacles, GE's enhanced delivery strategy, facilitated by its proprietary FLIGHT DECK operating model, aims to ensure a consistent supply of engines to maintain operations at HAL’s production facilities in Bengaluru and Nashik.
HAL has reportedly already finished assembling three Tejas Mk1A airframes, with the aircraft LA 5033 undertaking its inaugural flight in March 2024 using reserve Category-B engines. Furthermore, 11 additional jets are in advanced stages of assembly.
The 12 engines scheduled for delivery in 2025 will empower HAL to achieve its objective of delivering 12 jets by the year's conclusion, a target confirmed by HAL Chairman D.K. Sunil during Aero India 2025.
The Tejas Mk1A is an upgraded version of the Light Combat Aircraft, featuring improved avionics, an active electronically scanned array (AESA) radar, and superior electronic warfare capabilities, making it vital for the IAF's modernisation plans.
The timely arrival of these engines is critical as the IAF currently operates with 31 squadrons against a sanctioned strength of 42.5, and is in the process of retiring its aging MiG-21 fleet.
The significance of the program is highlighted by an order for 83 aircraft signed in February 2021, valued at ₹48,000 crore, and an in-principle approval for an additional 97 jets.
GE’s commitment to increase engine production to 20 units annually from 2026 will further bolster HAL’s expanded manufacturing capacity of 24 jets per year. This will allow the IAF to induct one complete squadron and partially establish a second one each year, significantly enhancing its operational preparedness and national defence capabilities.
