The S-400 is capable of destroying incoming hostile aircraft, missiles and even drones within a range of up to 400 km. It has a tracking capability of nearly 600 km.

New Delhi: India’s S-400 Triumf air defence system is currently in production in Russia and will undergo a series of trials before its arrival in the country by the end of 2021.

Sources said amid tensions with China at the Line of Actual Control in Ladakh, Russia will supply certain kinds of missiles and bombs for the Indian Air Force and the Army as part of emergency procurement.

Sources also said during the recent visit of Defence Minister Rajnath Singh to Russia, a review of all defence contracts signed and those in pipeline was done.

Diplomatic sources said India has sought emergency delivery of quite a few items.

They said India is aware that according to the contract, the delivery of the S-400 system would begin within 24 months from the payment of the first tranche of the $5.2-billion dollar deal.

Sources said even though the contract for the system, which will be India’s air defence umbrella and the main pillar of the Indian Air Force’s defence grid, was signed in October 2018, the payment took time because both countries had to find a way around the US sanctions against Russia.

Initially, it was expected that the first of the five S-400 systems will start coming in by the end of 2020. Following this, the rest of the four systems will be supplied over a period of four years.

“The production process involves a lot of computing and coding, which is very specific to the requirements of a particular customer. There are series of tests that are conducted, which are also followed up by training. The production can’t be simply sped up,” a source said.
