MOSCOW, October 9. /TASS/. Russia’s Defense Ministry will receive a complete set of S-400 Triumf air defense systems on October 10, prior to the scheduled date, the Russian defense concern Almaz-Antey’s press service said on Thursday.

Russian troops will receive the air defense systems on the single acceptance day at the Kapustin Yar training range, near Astrakhan, Volga Region, the press service said.

“The S-400 air defense systems will be delivered in the new format. The first supplies were made by different manufacturers in form of separate items to the Russian Armed Forces and the systems were directly integrated in troops. Now the complete set of S-400 air defense systems is being supplied,” the press service said.

S-400 Triumf air defense systems were put on combat duty in Russia's Southern Military District at the end of 2012 to replace S-300PM missiles.

Supplies of new air defense systems to the 4th Air Force and Air Defense Command in the District began in 2009. Since then, more than 60 pieces of new military hardware have been delivered and put into service.

The Triumf system is twice as effective as the previous systems and can attack 10 targets with up to 20 missiles. The S-400 uses 3 different missiles to cover its entire performance envelope.

According to the concern’s press service, the S-400 separate items have been modified, thus, the system due to be given to the armed forces on October 10 "considerably differs from the first systems, manufactured in 2007."

The single acceptance day was held in July 2014 for the first time on the decision of Russian Defense Minister Sergey Shoigu. Supplies of new, upgraded types of weaponry and hardware are growing. By 2020 the Russian Armed Forces will have at least 70% of advanced weapons.
