Hindustan Aeronautics Limited (HAL) has signed a $1 billion deal with the American firm GE Aerospace for the procurement of 113 F404 jet engines and a support package. These engines are intended to power the indigenous Light Combat Aircraft (LCA) Tejas Mark 1A fighters, which are set to replace the Indian Air Force's ageing MiG-21 fleet. This agreement strengthens the defense partnership between India and the US and is crucial for maintaining the operational readiness and indigenization drive of India's fighter jet program. Deliveries are expected to span from 2027 to 2032.
