Russia has reportedly delivered the second S-400 Triumf air defence missile system to Kamchatka Peninsula in the Russian Far East.

A Russian Pacific Fleet’s press service statement carried by Sputnik read: "More than 670t of cargo, and that’s 36 units of equipment for the S-400 missile defence system has arrived by sea to the city of Petropavlovsk-Kamchatsky."

According to the press service, the newly delivered system is the second of five missile defence systems that are scheduled to be stationed in the 1,250km-long peninsula.

"The system is expected to form the cornerstone of Russian air and missile defence by 2020."

Each S-400 system is delivered after comprehensive testing and training of personnel at the Kapustin Yar military range in the south of the country, as reported by RT.

An upgraded version of the S-300 missile system, the S-400 Triumf is a long-to-medium-range, surface-to-air missile system, and is designed to intercept a range of ground-based and airborne targets, including stealth aircraft, strategic carriers, and cruise and ballistic missiles at a distance of 400km.

Code-named the SA-21 Growler, the system has been developed by Almaz/Antei Concern and features three different missiles including the extremely long-range 40N6, 48N6 long-range and a 9M96 medium-range missile.

According to the news agency, the system is expected to form the cornerstone of Russian air and missile defence by 2020.

As of December last year, Russia had nine anti-aircraft missile regiment equipped with the S-400 systems across the country.

Apart from Russia, the system has also attracted interest from a number of foreign countries, including Saudi Arabia, Belarus and Turkey, as reported earlier by Vedomosti.

In November last year, Russian state-arms-exporter Rosoboronexport and the Chinese Defence Ministry signed a $3bn contract for the supply of at least six S-400 battalions.
