NEW DELHI — Avionics failures have led to the grounding of more than 20 of India’s Sukhoi Su-30 fighter jets, with Indian and Russian officials each suggesting the problem subsystems could have been supplied by the other side.
The avionics faults have included the head-up display and the mission computer, an Indian Air Force source said.
India has contracted to acquire 272 Russian-designed Su-30 aircraft, with 140 being license-produced by state-owned Hindustan Aeronautics Ltd. (HAL).
