The two new systems have several advancements over the S-400 and S-300, Sputnik reported without specifying the features stating that they are classified.

Russian S-500 and S-350 air defence systems, successors to the S-400 and S-350 respectively, are ‘almost ready,’ for deployment.

"The Armed Forces will soon begin receiving the S-350 systems," Aerospace Forces Deputy Commander Lieutenant General Yuri Grekhov told Krasnaya Zvezda.

He added that the development of the S-500, the successor to the S-300 and S-400 air defence systems has reached its final stage.

"The S-350 is tasked with "defence of administrative-political centres, most important objects and regions of the country, armed forces groups, from massive air strikes, including tactical and operative-tactical ballistic missiles," Grekhov said.

Accordingto Grekhov, the system has already passed the state's testing.

"The S-500, S-350 and the new radars feature high mobility and are able to deploy to and function in unprepared positions, he said.

The S-500 system is reportedly able to destroy targets up to 600 kilometres away. It is also believed to be able to track and simultaneously strike up to 10 ballistic targets moving at speeds up to 7 km/s (approximately Mach 20), according to the report.
