India, in 2018, signed a USD 5.43 billion deal with Russia for five squadrons of the S-400 Triumf missile system, a state-of-the-art air defence platform capable of engaging multiple aerial threats at long ranges. Out of the five, three squadrons have already been delivered.

This hypersonic cruise missile will be inspired by Russia’s 3M22 Zircon missile, which is a scramjet missile and is also equipped with nuclear capability.
