India has begun the process of buying 125 new fighter aircraft, a senior air force official has said.
Vice Chief of Air Staff SK Malik said in the southern Indian city of Bangalore on Wednesday that all options were open.
"We will go global. Perhaps F-16s will be there. Swedish Grippen, Mirage 2000 and MiG-29 will be there," he said.
The air force modernisation plan will replace its fleet of ageing and often unreliable Russian MiG-21s.
Air Marshal Malik was speaking at the annual conference of the Indian Society of Aerospace Medicine.
"We have not short-listed any aircraft nor discounted any," he said.
Air Marshal Malik said the initial process of identifying the required aircraft would take about two years.
