Below the Radar: Russia’s S-400, S-500 Set to Become Invisible to Enemies

In an age when stealth is the game-changing capability everyone aspires to achieve, Russia’s top-of-the-line air defense systems, the S-400 and the S-500, will receive an upgrade that will allow them to hide from enemy satellites, spy planes and radars, Izvestiya newspaper reported, citing an anonymous source in the Russian Defense Ministry.

The S-400 Triumf with the NATO designation SA-21 Growler and the S-500 Prometey, also known as the 55R6M Triumfator-M, will become undetectable thanks to a special container that will also be used to shield mobile command centers, air defense systems, radar stations and other hardware with complex electronic equipment.
