New Delhi, June 3 -- Russia is committed to delivering two more units of the S-400 air defence system, which was used in recent hostilities with Pakistan, to India by 2025-26, Russian deputy chief of mission Roman Babushkin said. India finalised a $5.43-billion deal with Russia in 2018 for five S-400 units and three have been delivered so far. Deliveries of the systems, which can engage multiple aerial threats at long ranges, were affected by Russia's conflict with Ukraine. Babushkin told the media that the delivery of the two remaining S-400 units is on track. "We heard that the S-400 performed very efficiently during the recent clashes between India and Pakistan. We have a long history of collaboration," he said.P7...
