Tejas Mk1A Production Set to Accelerate as GE Plans 20–22 More Engine Deliveries by Year-End

Hindustan Aeronautics Ltd (HAL) is expected to receive 20–22 additional F404-IN20 engines from GE Aerospace by the end of 2026, a development that could significantly ease production constraints for the Tejas Mk1A fighter aircraft. The additional engine deliveries are expected to help HAL accelerate aircraft assembly after earlier supply delays slowed production and deliveries to the Indian Air Force (IAF).

The improved engine supply comes at a crucial stage for India's indigenous fighter programme, with HAL aiming to deliver one complete Tejas Mk1A squadron by March, subject to the timely arrival of engines from GE Aerospace.

GE Aerospace to Supply 20–22 More F404-IN20 Engines

According to the latest update, GE Aerospace expects to deliver 20–22 additional F404-IN20 engines to HAL before the end of the year. The engines will power the Light Combat Aircraft (LCA) Tejas Mk1A, India's next-generation indigenous fighter jet developed for the Indian Air Force.

The fresh deliveries are expected to reduce one of the biggest production bottlenecks that affected the Tejas Mk1A programme over the past year.

Engine Supply Delays Had Slowed Tejas Production

Production of the Tejas Mk1A programme had been impacted by delays in engine deliveries, restricting HAL's ability to complete aircraft assembly and hand over fighter jets to the Indian Air Force.

With a more consistent supply of F404-IN20 engines, HAL is expected to increase production rates and accelerate the assembly of aircraft already in various stages of manufacturing.

The improved engine availability is expected to help the company gradually clear production backlogs while supporting scheduled deliveries over the coming months.

HAL Targets One Tejas Mk1A Squadron by March

HAL is working towards delivering one complete Tejas Mk1A squadron to the Indian Air Force by March, provided engine deliveries continue as planned.

A full squadron induction would mark an important milestone for India's indigenous defence manufacturing programme and strengthen the IAF's ongoing fleet modernisation efforts.

The Tejas Mk1A programme is considered a key component of India's strategy to replace ageing fighter aircraft with domestically manufactured platforms featuring advanced avionics, electronic warfare systems and improved combat capabilities.

Stronger Engine Supply to Boost Defence Manufacturing

A steady flow of F404-IN20 engines is expected to improve HAL's production planning and manufacturing efficiency.

Higher engine availability will allow the company to synchronise aircraft assembly lines, reduce delivery delays and gradually increase annual production capacity for the Tejas Mk1A programme.

The development also supports India's broader objective of expanding domestic defence manufacturing while reducing dependence on imported military platforms.

HAL Continues to Benefit From Strong Defence Order Book

HAL remains one of India's largest defence manufacturers with a strong order pipeline across fighter aircraft, helicopters, aero-engines and maintenance services.

The company has secured several major defence contracts in recent years, including orders for Light Combat Helicopters (LCH), Su-30MKI aircraft, AL-31FP engines and upgrades for Dornier-228 aircraft.

The continued execution of these projects, along with the Tejas Mk1A programme, is expected to remain a key growth driver for the company over the medium term.
