India has successfully engaged Russian S-400 Triumph air defense systems in the operation against terrorist targets in Pakistan and is now eyeing the latest S-500 Prometei systems, the Indian Defense News reported.

It said S-400 proved effective in combat conditions and intercepted targets at record distances. The engagement experience made Indian experts discuss the acquisition of S-500. India is interested in it also due to the changing situation in the region on the background of reports about the delivery to Pakistan of J-35A stealth fighter jets.

S-500 is "a strategic defensive asset of Russia and its export demands permission of the top national leadership," the portal said. However, a deal is not ruled out due to long-standing and trustworthy cooperation between Russia and India in the defense sphere.
