The Indian Air Force has been significantly enhancing deployment of its front line jets, attack helicopters in all its key bases guarding the LAC. This is in view of heightened border tension with China in eastern Ladakh. The Indian and Chinese armies are engaged in a tough standoff in multiple locations in eastern Ladakh for the last seven weeks. The tension escalated after 20 Indian soldiers were killed in a violent clash in Galwan Valley on June 15. The Chinese side also suffered casualties.
