Russia has started delivering the S-400 Triumf surface-to-air missile systems to India, the deliveries are going as planned, Director of the Federal Service for Military-Technical Cooperation (FSMTC) Dmitry Shugaev told Sputnik ahead of the Dubai Airshow.

"The supplies of the S-400 air defense system to India have started and are proceeding on schedule," Shugaev said.

The S-400 has already entered service in China and Turkey. Russia and India signed a contract on the delivery of S-400s in October 2018.
