the Philippine Air Force's MRF project. Sri Lanka It has been reported that Sri Lanka has shown interest in purchasing the Tejas to replace its aging fleets of IAI Kfir and Chengdu J-7 aircraft. The programme is for the acquisition of 8 to 12 aircraft and is to be pursued through a government-government basic agreement. In 2021, it was decided to overhaul the Kfirs, instead of buying new aircraft, which would cost around $40 million per unit compared to $49 million in total for overhauling the five Kfirs.
