Islamabad, whose air force primarily operates Chinese-made jets and U.S. F-16s, has previously denied that India downed any Pakistani aircraft during the fighting.

Most of the aircraft were downed by India’s Russian-made S-400 surface-to-air missile system, citing electronic tracking data as confirmation.

India's air force announced it shot down six Pakistani military aircraft during May clashes, marking a major military confrontation. The Indian Air Chief cited the use of the S-400 missile system and electronic tracking data to confirm these strikes.

India shot down five Pakistani fighter jets and one other military aircraft during clashes in May, India's air force chief said on Saturday, the first such statement by the country months after its worst military conflict in decades with its neighbour.

Air force chief says S-400 air defence systems took down most of the Pakistani planes; Pakistan rejects statement.
