Hindustan Aeronautics Limited (HAL) is adapting to new challenges in the production of its Tejas Mk1A fighter jets following further delays in the delivery of the crucial GE F-404 engines.

Originally expected by mid-2024, the delay in delivery 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 increase fleet capabilities.

However, ongoing delays have raised concerns within the IAF regarding the potential impact on its operational readiness.

To keep production on track, HAL has chosen Category B engines, which are adequate for pre-delivery flight tests and ensure the aircraft remains in airworthy condition. These engines will be used for necessary testing and quality assurance until the GE F-404 main engines are delivered.

A HAL official talks to India Today TVstressed that the move was necessary to maintain momentum.

“Our goal is to ensure that there is no production downtime or standby. By using Category B engines, we can conduct critical flight tests and keep pace with our production goals. Once the GE engines arrive, we will seamlessly integrate them into the aircraft. ” said the official.

The delays in engine deliveries have been attributed to ongoing disruptions in the supply chain. However, HAL’s strategic decision to use interim engines reflects its commitment to maintain production schedules and ensure 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 that the aircraft meets all performance criteria before final delivery.

This approach is seen as a pragmatic solution to address the current bottlenecks and avoid further delays in the deployment of the Tejas Mk1A, which is an important part of India’s efforts to modernize its air force with indigenously produced defense technology.
