Tejas Mk1A project: Engine delay forces defence firm to invoke contingency plan

Hindustan Aeronautics Limited (HAL) is adapting to fresh challenges in the production of its Tejas Mk1A fighter aircraft following further delays in the delivery of the crucial GE F-404 engines.
Initially expected by mid-2024, the delay in the supply of these engines has forced HAL to implement a contingency plan that involves using Category B F-404 engines for the early production models of the Tejas Mk1A.
The Tejas Mk1A represents a key advancement for the Indian Air Force (IAF), incorporating upgraded avionics and advanced radar systems to boost fleet capabilities.
However, ongoing delays have raised concerns within the IAF regarding the potential impact on its operational readiness.
To keep the production on track, HAL has opted for Category B engines, which are adequate for pre-delivery flight tests and ensure the aircraft remains in a flyable condition. These engines will be used for essential testing and quality assurance until the main GE F-404 engines are delivered.
A HAL official, speaking to India Today TV, emphasised that the move was necessary to maintain momentum.
“Our goal is to ensure there is no lapse in production or readiness. Using Category B engines allows us to conduct essential flight tests and keep up with our production targets. Once the GE engines arrive, we will seamlessly integrate them into the aircraft,” the official said.
The delay in engine deliveries has been attributed to ongoing supply chain disruptions. However, HAL’s strategic decision to use interim engines reflects its commitment to maintaining production schedules and ensuring that the Tejas Mk1A remains on track for eventual delivery to the IAF.
Once the GE F-404 engines are available, HAL plans to conduct 2-3 pre-delivery flight tests in collaboration with the IAF to ensure the aircraft meets all performance criteria before final delivery.
This approach is seen as a pragmatic solution to address the current bottlenecks and avoid any further delays in the Tejas Mk1A’s rollout, which is a key part of India’s efforts to modernise its air force with domestically produced defence technologies.
