GE Aerospace Delivers 7th F404-IN20 Engine to HAL for Tejas Mk1A Production

GE Aerospace has delivered the seventh F404-IN20 turbofan engine to Hindustan Aeronautics Limited (HAL), accelerating production of the Tejas Mk1A fighter jet for the Indian Air Force.

The F404-IN20 is the derivative of General Electric’s F404 engine, jointly developed by GE and HAL under licence. It produces approximately 11,200 pounds of thrust in military power and 19,200 pounds in afterburner configuration. This variant was specifically configured for the Tejas lightweight combat aircraft programme.

The Tejas Mk1A represents an upgrade over the initial Mk1 variant, incorporating enhanced avionics, improved aerodynamics, and expanded weapon integration. The aircraft has been cleared for series production to meet the IAF’s requirement for 83 aircraft under the initial contract. Each airframe requires two engines, making engine supply a critical bottleneck in production scheduling.

HAL and GE established the F404-IN20 supply chain through a long-term development and production agreement signed in 2012. The engine comes partially assembled from GE facilities in the United States, with final assembly, testing, and integration performed at HAL’s Bangalore division. This arrangement balances technology access with indigenous production capability, aligning with India’s strategic push toward self-reliance in defence manufacturing.

The Tejas programme, initiated by DRDO in the 1980s, took nearly three decades to achieve operational clearance with the IAF in 2019. The Mk1A variant, which entered service in 2021, incorporates lessons learned from fleet operations and incorporates mid-life improvements in radar capability, sensor fusion, and electronic warfare systems without a major redesign cycle.

Engine delivery acceleration is particularly significant given the IAF’s broader modernisation timeline. The service operates over 230 fighter aircraft across platforms including Sukhoi Su-30MKI, HAL Tejas, and legacy MiG-29s and Mirage 2000s. The Tejas fleet expansion directly addresses the service’s target of maintaining 40 operational squadrons, a goal constrained by aging airframes and delayed procurement of advanced platforms.

GE Aerospace’s supply consistency has been instrumental in maintaining production momentum across defence supply chains. The company also supplies engines for India’s naval helicopter programme and provides maintenance and overhaul services at HAL facilities, creating a comprehensive partnership footprint across multiple defence platforms.

The 7th engine delivery marks steady progress in HAL’s current production run, with further deliveries expected to accelerate production cadence through 2024 and beyond as the IAF works to populate its fighter squadrons with modern, indigenous-designed aircraft.
