Gazelle missles are short range.
This topic is very classifid till now.
The Russian air force has said that it will start testing S-400 against "ICBM classs" targets
Actually the S-400 regiments are still in deployment stage they have not been fielded in sufficent
But no words are heard from MoD about the capabilities of S-400.
Although we know that S-400 radar has capacity to rival the best of ABM radars in the world.
Russia’s missile-attack warning radars are far superior to any foreign counterparts, a top defense official said Friday.
Russia has an “absolute lead,” “no one else can match these stations,” Deputy Defense Minister Yury Borisov said after visiting a Voronezh-M radar in Siberia’s Irkutsk Region.
The Voronezh-M has greatly surpassed previous-generation systems, in particular the Dnepr, the official said, adding that the Voronezh-M had a range of 6,500 kilometers, higher resolution and a broader field of vision.
The radar system will “reliably protect our southeastern sector and the northeastern part of the Pacific,” he said.
His comments echoed ones last month by General Staff chief Valery Gerasimov, who said Russia was building a new aerospace defense system that would guarantee detection of enemy ballistic and long-range cruise missiles at blastoff.
russian ABM radars are best
