New Delhi: India and Russia will sign the $5 Billion S-400 missile deal on Saturday during Vladimir Putin’s visit to Goa.

The agreement would be signed at the BRICS summit where Prime Minister Narendra Modi will meet the president of Russia Vladimir Putin separately.

“An agreement on the delivery of S-400 ‘Triumph’ anti-missile defence systems and other deals will be signed as a result of the talks,” Putin’s aide Yuri Ushakov has been quoted as saying by the Russian agencies.

President Vladimir Putin on Thursday had said that Russia remained the top supplier of most advanced weapons and defence technology to its “privileged strategic partner” India.

“Russia remains in the lead in terms of both direct supplies of most advanced weapons and military equipment and conducting joint researches with India as well as producing goods for military purposes. Our countries actively collaborate in the military technical field,” Putin said in an exclusive interview.

The agreement for the helicopters was signed by the two countries during Modi’s visit to Moscow last December.

The S-400 anti-aircraft missiles are going to replace the existing Cheetah and Cheetak choppers used by the Indian armed forces.
